GNU GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The GNU General Public License is a free, copyleft license for
software and other kinds of works.
The licenses for most software and other practical works are designed
to take away your freedom to share and change the works. By contrast,
the GNU General Public License is intended to guarantee your freedom to
share and change all versions of a program--to make sure it remains free
software for all its users. We, the Free Software Foundation, use the
GNU General Public License for most of our software; it applies also to
any other work released this way by its authors. You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
them if you wish), that you receive source code or can get it if you
want it, that you can change the software or use pieces of it in new
free programs, and that you know you can do these things.
To protect your rights, we need to prevent others from denying you
these rights or asking you to surrender the rights. Therefore, you have
certain responsibilities if you distribute copies of the software, or if
you modify it: responsibilities to respect the freedom of others.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must pass on to the recipients the same
freedoms that you received. You must make sure that they, too, receive
or can get the source code. And you must show them these terms so they
know their rights.
Developers that use the GNU GPL protect your rights with two steps:
(1) assert copyright on the software, and (2) offer you this License
giving you legal permission to copy, distribute and/or modify it.
For the developers' and authors' protection, the GPL clearly explains
that there is no warranty for this free software. For both users' and
authors' sake, the GPL requires that modified versions be marked as
changed, so that their problems will not be attributed erroneously to
authors of previous versions.
Some devices are designed to deny users access to install or run
modified versions of the software inside them, although the manufacturer
can do so. This is fundamentally incompatible with the aim of
protecting users' freedom to change the software. The systematic
pattern of such abuse occurs in the area of products for individuals to
use, which is precisely where it is most unacceptable. Therefore, we
have designed this version of the GPL to prohibit the practice for those
products. If such problems arise substantially in other domains, we
stand ready to extend this provision to those domains in future versions
of the GPL, as needed to protect the freedom of users.
Finally, every program is threatened constantly by software patents.
States should not allow patents to restrict development and use of
software on general-purpose computers, but in those that do, we wish to
avoid the special danger that patents applied to a free program could
make it effectively proprietary. To prevent this, the GPL assures that
patents cannot be used to render the program non-free.
The precise terms and conditions for copying, distribution and
modification follow.
TERMS AND CONDITIONS
0. Definitions.
"This License" refers to version 3 of the GNU General Public License.
"Copyright" also means copyright-like laws that apply to other kinds of
works, such as semiconductor masks.
"The Program" refers to any copyrightable work licensed under this
License. Each licensee is addressed as "you". "Licensees" and
"recipients" may be individuals or organizations.
To "modify" a work means to copy from or adapt all or part of the work
in a fashion requiring copyright permission, other than the making of an
exact copy. The resulting work is called a "modified version" of the
earlier work or a work "based on" the earlier work.
A "covered work" means either the unmodified Program or a work based
on the Program.
To "propagate" a work means to do anything with it that, without
permission, would make you directly or secondarily liable for
infringement under applicable copyright law, except executing it on a
computer or modifying a private copy. Propagation includes copying,
distribution (with or without modification), making available to the
public, and in some countries other activities as well.
To "convey" a work means any kind of propagation that enables other
parties to make or receive copies. Mere interaction with a user through
a computer network, with no transfer of a copy, is not conveying.
An interactive user interface displays "Appropriate Legal Notices"
to the extent that it includes a convenient and prominently visible
feature that (1) displays an appropriate copyright notice, and (2)
tells the user that there is no warranty for the work (except to the
extent that warranties are provided), that licensees may convey the
work under this License, and how to view a copy of this License. If
the interface presents a list of user commands or options, such as a
menu, a prominent item in the list meets this criterion.
1. Source Code.
The "source code" for a work means the preferred form of the work
for making modifications to it. "Object code" means any non-source
form of a work.
A "Standard Interface" means an interface that either is an official
standard defined by a recognized standards body, or, in the case of
interfaces specified for a particular programming language, one that
is widely used among developers working in that language.
The "System Libraries" of an executable work include anything, other
than the work as a whole, that (a) is included in the normal form of
packaging a Major Component, but which is not part of that Major
Component, and (b) serves only to enable use of the work with that
Major Component, or to implement a Standard Interface for which an
implementation is available to the public in source code form. A
"Major Component", in this context, means a major essential component
(kernel, window system, and so on) of the specific operating system
(if any) on which the executable work runs, or a compiler used to
produce the work, or an object code interpreter used to run it.
The "Corresponding Source" for a work in object code form means all
the source code needed to generate, install, and (for an executable
work) run the object code and to modify the work, including scripts to
control those activities. However, it does not include the work's
System Libraries, or general-purpose tools or generally available free
programs which are used unmodified in performing those activities but
which are not part of the work. For example, Corresponding Source
includes interface definition files associated with source files for
the work, and the source code for shared libraries and dynamically
linked subprograms that the work is specifically designed to require,
such as by intimate data communication or control flow between those
subprograms and other parts of the work.
The Corresponding Source need not include anything that users
can regenerate automatically from other parts of the Corresponding
Source.
The Corresponding Source for a work in source code form is that
same work.
2. Basic Permissions.
All rights granted under this License are granted for the term of
copyright on the Program, and are irrevocable provided the stated
conditions are met. This License explicitly affirms your unlimited
permission to run the unmodified Program. The output from running a
covered work is covered by this License only if the output, given its
content, constitutes a covered work. This License acknowledges your
rights of fair use or other equivalent, as provided by copyright law.
You may make, run and propagate covered works that you do not
convey, without conditions so long as your license otherwise remains
in force. You may convey covered works to others for the sole purpose
of having them make modifications exclusively for you, or provide you
with facilities for running those works, provided that you comply with
the terms of this License in conveying all material for which you do
not control copyright. Those thus making or running the covered works
for you must do so exclusively on your behalf, under your direction
and control, on terms that prohibit them from making any copies of
your copyrighted material outside their relationship with you.
Conveying under any other circumstances is permitted solely under
the conditions stated below. Sublicensing is not allowed; section 10
makes it unnecessary.
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological
measure under any applicable law fulfilling obligations under article
11 of the WIPO copyright treaty adopted on 20 December 1996, or
similar laws prohibiting or restricting circumvention of such
measures.
When you convey a covered work, you waive any legal power to forbid
circumvention of technological measures to the extent such circumvention
is effected by exercising rights under this License with respect to
the covered work, and you disclaim any intention to limit operation or
modification of the work as a means of enforcing, against the work's
users, your or third parties' legal rights to forbid circumvention of
technological measures.
4. Conveying Verbatim Copies.
You may convey verbatim copies of the Program's source code as you
receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice;
keep intact all notices stating that this License and any
non-permissive terms added in accord with section 7 apply to the code;
keep intact all notices of the absence of any warranty; and give all
recipients a copy of this License along with the Program.
You may charge any price or no price for each copy that you convey,
and you may offer support or warranty protection for a fee.
5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to
produce it from the Program, in the form of source code under the
terms of section 4, provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified
it, and giving a relevant date.
b) The work must carry prominent notices stating that it is
released under this License and any conditions added under section
7. This requirement modifies the requirement in section 4 to
"keep intact all notices".
c) You must license the entire work, as a whole, under this
License to anyone who comes into possession of a copy. This
License will therefore apply, along with any applicable section 7
additional terms, to the whole of the work, and all its parts,
regardless of how they are packaged. This License gives no
permission to license the work in any other way, but it does not
invalidate such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display
Appropriate Legal Notices; however, if the Program has interactive
interfaces that do not display Appropriate Legal Notices, your
work need not make them do so.
A compilation of a covered work with other separate and independent
works, which are not by their nature extensions of the covered work,
and which are not combined with it such as to form a larger program,
in or on a volume of a storage or distribution medium, is called an
"aggregate" if the compilation and its resulting copyright are not
used to limit the access or legal rights of the compilation's users
beyond what the individual works permit. Inclusion of a covered work
in an aggregate does not cause this License to apply to the other
parts of the aggregate.
6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms
of sections 4 and 5, provided that you also convey the
machine-readable Corresponding Source under the terms of this License,
in one of these ways:
a) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by the
Corresponding Source fixed on a durable physical medium
customarily used for software interchange.
b) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by a
written offer, valid for at least three years and valid for as
long as you offer spare parts or customer support for that product
model, to give anyone who possesses the object code either (1) a
copy of the Corresponding Source for all the software in the
product that is covered by this License, on a durable physical
medium customarily used for software interchange, for a price no
more than your reasonable cost of physically performing this
conveying of source, or (2) access to copy the
Corresponding Source from a network server at no charge.
c) Convey individual copies of the object code with a copy of the
written offer to provide the Corresponding Source. This
alternative is allowed only occasionally and noncommercially, and
only if you received the object code with such an offer, in accord
with subsection 6b.
d) Convey the object code by offering access from a designated
place (gratis or for a charge), and offer equivalent access to the
Corresponding Source in the same way through the same place at no
further charge. You need not require recipients to copy the
Corresponding Source along with the object code. If the place to
copy the object code is a network server, the Corresponding Source
may be on a different server (operated by you or a third party)
that supports equivalent copying facilities, provided you maintain
clear directions next to the object code saying where to find the
Corresponding Source. Regardless of what server hosts the
Corresponding Source, you remain obligated to ensure that it is
available for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided
you inform other peers where the object code and Corresponding
Source of the work are being offered to the general public at no
charge under subsection 6d.
A separable portion of the object code, whose source code is excluded
from the Corresponding Source as a System Library, need not be
included in conveying the object code work.
A "User Product" is either (1) a "consumer product", which means any
tangible personal property which is normally used for personal, family,
or household purposes, or (2) anything designed or sold for incorporation
into a dwelling. In determining whether a product is a consumer product,
doubtful cases shall be resolved in favor of coverage. For a particular
product received by a particular user, "normally used" refers to a
typical or common use of that class of product, regardless of the status
of the particular user or of the way in which the particular user
actually uses, or expects or is expected to use, the product. A product
is a consumer product regardless of whether the product has substantial
commercial, industrial or non-consumer uses, unless such uses represent
the only significant mode of use of the product.
"Installation Information" for a User Product means any methods,
procedures, authorization keys, or other information required to install
and execute modified versions of a covered work in that User Product from
a modified version of its Corresponding Source. The information must
suffice to ensure that the continued functioning of the modified object
code is in no case prevented or interfered with solely because
modification has been made.
If you convey an object code work under this section in, or with, or
specifically for use in, a User Product, and the conveying occurs as
part of a transaction in which the right of possession and use of the
User Product is transferred to the recipient in perpetuity or for a
fixed term (regardless of how the transaction is characterized), the
Corresponding Source conveyed under this section must be accompanied
by the Installation Information. But this requirement does not apply
if neither you nor any third party retains the ability to install
modified object code on the User Product (for example, the work has
been installed in ROM).
The requirement to provide Installation Information does not include a
requirement to continue to provide support service, warranty, or updates
for a work that has been modified or installed by the recipient, or for
the User Product in which it has been modified or installed. Access to a
network may be denied when the modification itself materially and
adversely affects the operation of the network or violates the rules and
protocols for communication across the network.
Corresponding Source conveyed, and Installation Information provided,
in accord with this section must be in a format that is publicly
documented (and with an implementation available to the public in
source code form), and must require no special password or key for
unpacking, reading or copying.
7. Additional Terms.
"Additional permissions" are terms that supplement the terms of this
License by making exceptions from one or more of its conditions.
Additional permissions that are applicable to the entire Program shall
be treated as though they were included in this License, to the extent
that they are valid under applicable law. If additional permissions
apply only to part of the Program, that part may be used separately
under those permissions, but the entire Program remains governed by
this License without regard to the additional permissions.
When you convey a copy of a covered work, you may at your option
remove any additional permissions from that copy, or from any part of
it. (Additional permissions may be written to require their own
removal in certain cases when you modify the work.) You may place
additional permissions on material, added by you to a covered work,
for which you have or can give appropriate copyright permission.
Notwithstanding any other provision of this License, for material you
add to a covered work, you may (if authorized by the copyright holders of
that material) supplement the terms of this License with terms:
a) Disclaiming warranty or limiting liability differently from the
terms of sections 15 and 16 of this License; or
b) Requiring preservation of specified reasonable legal notices or
author attributions in that material or in the Appropriate Legal
Notices displayed by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or
requiring that modified versions of such material be marked in
reasonable ways as different from the original version; or
d) Limiting the use for publicity purposes of names of licensors or
authors of the material; or
e) Declining to grant rights under trademark law for use of some
trade names, trademarks, or service marks; or
f) Requiring indemnification of licensors and authors of that
material by anyone who conveys the material (or modified versions of
it) with contractual assumptions of liability to the recipient, for
any liability that these contractual assumptions directly impose on
those licensors and authors.
All other non-permissive additional terms are considered "further
restrictions" within the meaning of section 10. If the Program as you
received it, or any part of it, contains a notice stating that it is
governed by this License along with a term that is a further
restriction, you may remove that term. If a license document contains
a further restriction but permits relicensing or conveying under this
License, you may add to a covered work material governed by the terms
of that license document, provided that the further restriction does
not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you
must place, in the relevant source files, a statement of the
additional terms that apply to those files, or a notice indicating
where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the
form of a separately written license, or stated as exceptions;
the above requirements apply either way.
8. Termination.
You may not propagate or modify a covered work except as expressly
provided under this License. Any attempt otherwise to propagate or
modify it is void, and will automatically terminate your rights under
this License (including any patent licenses granted under the third
paragraph of section 11).
However, if you cease all violation of this License, then your
license from a particular copyright holder is reinstated (a)
provisionally, unless and until the copyright holder explicitly and
finally terminates your license, and (b) permanently, if the copyright
holder fails to notify you of the violation by some reasonable means
prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is
reinstated permanently if the copyright holder notifies you of the
violation by some reasonable means, this is the first time you have
received notice of violation of this License (for any work) from that
copyright holder, and you cure the violation prior to 30 days after
your receipt of the notice.
Termination of your rights under this section does not terminate the
licenses of parties who have received copies or rights from you under
this License. If your rights have been terminated and not permanently
reinstated, you do not qualify to receive new licenses for the same
material under section 10.
9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or
run a copy of the Program. Ancillary propagation of a covered work
occurring solely as a consequence of using peer-to-peer transmission
to receive a copy likewise does not require acceptance. However,
nothing other than this License grants you permission to propagate or
modify any covered work. These actions infringe copyright if you do
not accept this License. Therefore, by modifying or propagating a
covered work, you indicate your acceptance of this License to do so.
10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically
receives a license from the original licensors, to run, modify and
propagate that work, subject to this License. You are not responsible
for enforcing compliance by third parties with this License.
An "entity transaction" is a transaction transferring control of an
organization, or substantially all assets of one, or subdividing an
organization, or merging organizations. If propagation of a covered
work results from an entity transaction, each party to that
transaction who receives a copy of the work also receives whatever
licenses to the work the party's predecessor in interest had or could
give under the previous paragraph, plus a right to possession of the
Corresponding Source of the work from the predecessor in interest, if
the predecessor has it or can get it with reasonable efforts.
You may not impose any further restrictions on the exercise of the
rights granted or affirmed under this License. For example, you may
not impose a license fee, royalty, or other charge for exercise of
rights granted under this License, and you may not initiate litigation
(including a cross-claim or counterclaim in a lawsuit) alleging that
any patent claim is infringed by making, using, selling, offering for
sale, or importing the Program or any portion of it.
11. Patents.
A "contributor" is a copyright holder who authorizes use under this
License of the Program or a work on which the Program is based. The
work thus licensed is called the contributor's "contributor version".
A contributor's "essential patent claims" are all patent claims
owned or controlled by the contributor, whether already acquired or
hereafter acquired, that would be infringed by some manner, permitted
by this License, of making, using, or selling its contributor version,
but do not include claims that would be infringed only as a
consequence of further modification of the contributor version. For
purposes of this definition, "control" includes the right to grant
patent sublicenses in a manner consistent with the requirements of
this License.
Each contributor grants you a non-exclusive, worldwide, royalty-free
patent license under the contributor's essential patent claims, to
make, use, sell, offer for sale, import and otherwise run, modify and
propagate the contents of its contributor version.
In the following three paragraphs, a "patent license" is any express
agreement or commitment, however denominated, not to enforce a patent
(such as an express permission to practice a patent or covenant not to
sue for patent infringement). To "grant" such a patent license to a
party means to make such an agreement or commitment not to enforce a
patent against the party.
If you convey a covered work, knowingly relying on a patent license,
and the Corresponding Source of the work is not available for anyone
to copy, free of charge and under the terms of this License, through a
publicly available network server or other readily accessible means,
then you must either (1) cause the Corresponding Source to be so
available, or (2) arrange to deprive yourself of the benefit of the
patent license for this particular work, or (3) arrange, in a manner
consistent with the requirements of this License, to extend the patent
license to downstream recipients. "Knowingly relying" means you have
actual knowledge that, but for the patent license, your conveying the
covered work in a country, or your recipient's use of the covered work
in a country, would infringe one or more identifiable patents in that
country that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction or
arrangement, you convey, or propagate by procuring conveyance of, a
covered work, and grant a patent license to some of the parties
receiving the covered work authorizing them to use, propagate, modify
or convey a specific copy of the covered work, then the patent license
you grant is automatically extended to all recipients of the covered
work and works based on it.
A patent license is "discriminatory" if it does not include within
the scope of its coverage, prohibits the exercise of, or is
conditioned on the non-exercise of one or more of the rights that are
specifically granted under this License. You may not convey a covered
work if you are a party to an arrangement with a third party that is
in the business of distributing software, under which you make payment
to the third party based on the extent of your activity of conveying
the work, and under which the third party grants, to any of the
parties who would receive the covered work from you, a discriminatory
patent license (a) in connection with copies of the covered work
conveyed by you (or copies made from those copies), or (b) primarily
for and in connection with specific products or compilations that
contain the covered work, unless you entered into that arrangement,
or that patent license was granted, prior to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting
any implied license or other defenses to infringement that may
otherwise be available to you under applicable patent law.
12. No Surrender of Others' Freedom.
If conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot convey a
covered work so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you may
not convey it at all. For example, if you agree to terms that obligate you
to collect a royalty for further conveying from those to whom you convey
the Program, the only way you could satisfy both those terms and this
License would be to refrain entirely from conveying the Program.
13. Use with the GNU Affero General Public License.
Notwithstanding any other provision of this License, you have
permission to link or combine any covered work with a work licensed
under version 3 of the GNU Affero General Public License into a single
combined work, and to convey the resulting work. The terms of this
License will continue to apply to the part which is the covered work,
but the special requirements of the GNU Affero General Public License,
section 13, concerning interaction through a network will apply to the
combination as such.
14. Revised Versions of this License.
The Free Software Foundation may publish revised and/or new versions of
the GNU General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the
Program specifies that a certain numbered version of the GNU General
Public License "or any later version" applies to it, you have the
option of following the terms and conditions either of that numbered
version or of any later version published by the Free Software
Foundation. If the Program does not specify a version number of the
GNU General Public License, you may choose any version ever published
by the Free Software Foundation.
If the Program specifies that a proxy can decide which future
versions of the GNU General Public License can be used, that proxy's
public statement of acceptance of a version permanently authorizes you
to choose that version for the Program.
Later license versions may give you additional or different
permissions. However, no additional obligations are imposed on any
author or copyright holder as a result of your choosing to follow a
later version.
15. Disclaimer of Warranty.
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. Limitation of Liability.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES.
17. Interpretation of Sections 15 and 16.
If the disclaimer of warranty and limitation of liability provided
above cannot be given local legal effect according to their terms,
reviewing courts shall apply local law that most closely approximates
an absolute waiver of all civil liability in connection with the
Program, unless a warranty or assumption of liability accompanies a
copy of the Program in return for a fee.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
state the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software: you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation, either version 3 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program. If not, see <https://www.gnu.org/licenses/>.
Also add information on how to contact you by electronic and paper mail.
If the program does terminal interaction, make it output a short
notice like this when it starts in an interactive mode:
<program> Copyright (C) <year> <name of author>
This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, your program's commands
might be different; for a GUI interface, you would use an "about box".
You should also get your employer (if you work as a programmer) or school,
if any, to sign a "copyright disclaimer" for the program, if necessary.
For more information on this, and how to apply and follow the GNU GPL, see
<https://www.gnu.org/licenses/>.
The GNU General Public License does not permit incorporating your program
into proprietary programs. If your program is a subroutine library, you
may consider it more useful to permit linking proprietary applications with
the library. If this is what you want to do, use the GNU Lesser General
Public License instead of this License. But first, please read
<https://www.gnu.org/philosophy/why-not-lgpl.html>.

Port of GNU Make to 32-bit protected mode on MSDOS and MS-Windows.
Builds with DJGPP v2 port of GNU C/C++ compiler and utilities.
New (since 3.74) DOS-specific features:
1. Supports long filenames when run from DOS box on Windows 9x.
2. Supports both stock DOS COMMAND.COM and Unix-style shells
(details in 'Notes' below).
3. Supports DOS drive letters in dependencies and pattern rules.
4. Better support for DOS-style backslashes in pathnames (but see
'Notes' below).
5. The $(shell) built-in can run arbitrary complex commands,
including pipes and redirection, even when COMMAND.COM is your
shell.
6. Can be built without floating-point code (see below).
7. Supports signals in child programs and restores the original
directory if the child was interrupted.
8. Can be built without (a previous version of) Make.
9. The build process requires only standard tools. (Optional
targets like "check:" still need additional programs, though,
see below.)
10. Beginning with v3.78, the test suite works in the DJGPP
environment (requires Perl and auxiliary tools; see below).
To install a binary distribution:
Simply unzip the makNNNb.zip file (where NNN is the version number)
preserving the directory structure (-d switch if you use PKUNZIP).
If you are installing Make on Windows 9X or Windows 2000, use an
unzip program that supports long filenames in zip files. After
unzipping, make sure the directory with make.exe is on your PATH,
and that's all you need to use Make.
To build from sources:
1. Unzip the archive, preserving the directory structure (-d switch
if you use PKUNZIP). If you build Make on Windows 9X or Windows
2000, use an unzip program that supports long filenames in zip
files.
If you are unpacking an official GNU source distribution, use
either DJTAR (which is part of the DJGPP development
environment), or the DJGPP port of GNU Tar.
2. If you have a working Make already, you can run:
make -f Basic.mk
3. If you don't have a working Make already you can bootstrap one
by running:
.\builddos.bat
4. If you are building from outside of the source directory, you
need to tell Make where the sources are, like this:
make -f c:/djgpp/gnu/make/Basic.mk SRCDIR=c:/djgpp/gnu/make
or:
c:/djgpp/gnu/make/builddos.bat c:/djgpp/gnu/make
5. To run the test suite, type "make check". This requires a Unix
shell (I used the DJGPP port of Bash 2.03), Perl, Sed, Fileutils
and Sh-utils.
6. To install copy make.exe to the preferred location.
Since GNU Make 4.3, support for customized platform installations
has been removed. If you'd like to collaborate on reinstating
these capabilities, contact bug-make@gnu.org.
Notes:
-----
1. The shell issue.
This is probably the most significant improvement, first
introduced in the port of GNU Make 3.75.
The original behavior of GNU Make is to invoke commands
directly, as long as they don't include characters special to
the shell or internal shell commands, because that is faster.
When shell features like redirection or filename wildcards are
involved, Make calls the shell.
This port supports both DOS shells (the stock COMMAND.COM and its
4DOS/NDOS replacements), and Unix-style shells (tested with the
venerable Stewartson's 'ms_sh' 2.3 and the DJGPP port of 'bash' by
Daisuke Aoyama <jack@st.rim.or.jp>).
When the $SHELL variable points to a Unix-style shell, Make
works just like you'd expect on Unix, calling the shell for any
command that involves characters special to the shell or
internal shell commands. The only difference is that, since
there is no standard way to pass command lines longer than the
infamous DOS 126-character limit, this port of Make writes the
command line to a temporary disk file and then invokes the shell
on that file.
If $SHELL points to a DOS-style shell, however, Make will not
call it automatically, as it does with Unix shells. Stock
COMMAND.COM is too dumb and would unnecessarily limit the
functionality of Make. For example, you would not be able to
use long command lines in commands that use redirection or
pipes. Therefore, when presented with a DOS shell, this port of
Make will emulate most of the shell functionality, like
redirection and pipes, and shall only call the shell when a
batch file or a command internal to the shell is invoked. (Even
when a command is an internal shell command, Make will first
search the $PATH for it, so that if a Makefile calls 'mkdir',
you can install, say, a port of GNU 'mkdir' and have it called
in that case.)
The key to all this is the extended functionality of 'spawn' and
'system' functions from the DJGPP library; this port just calls
'system' where it would invoke the shell on Unix. The most
important aspect of these functions is that they use a special
mechanism to pass long (up to 16KB) command lines to DJGPP
programs. In addition, 'system' emulates some internal
commands, like 'cd' (so that you can now use forward slashes
with it, and can also change the drive if the directory is on
another drive). Another aspect worth mentioning is that you can
call Unix shell scripts directly, provided that the shell whose
name is mentioned on the first line of the script is installed
anywhere along the $PATH. It is impossible to tell here
everything about these functions; refer to the DJGPP library
reference for more details.
The $(shell) built-in is implemented in this port by calling
'popen'. Since 'popen' calls 'system', the above considerations
are valid for $(shell) as well. In particular, you can put
arbitrary complex commands, including pipes and redirection,
inside $(shell), which is in many cases a valid substitute for
the Unix-style command substitution (`command`) feature.
2. "SHELL=/bin/sh" -- or is it?
Many Unix Makefiles include a line which sets the SHELL, for
those versions of Make which don't have this as the default.
Since many DOS systems don't have 'sh' installed (in fact, most
of them don't even have a '/bin' directory), this port takes
such directives with a grain of salt. It will only honor such a
directive if the basename of the shell name (like 'sh' in the
above example) can indeed be found in the directory that is
mentioned in the SHELL= line ('/bin' in the above example), or
in the current working directory, or anywhere on the $PATH (in
that order). If the basename doesn't include a filename
extension, Make will look for any known extension that indicates
an executable file (.exe, .com, .bat, .btm, .sh, and even .sed
and .pl). If any such file is found, then $SHELL will be
defined to the exact pathname of that file, and that shell will
hence be used for the rest of processing. But if the named
shell is *not* found, the line which sets it will be effectively
ignored, leaving the value of $SHELL as it was before. Since a
lot of decisions that this port makes depend on the gender of
the shell, I feel it doesn't make any sense to tailor Make's
behavior to a shell which is nowhere to be found.
Note that the above special handling of "SHELL=" only happens
for Makefiles; if you set $SHELL in the environment or on the
Make command line, you are expected to give the complete
pathname of the shell, including the filename extension.
The default value of $SHELL is computed as on Unix (see the Make
manual for details), except that if $SHELL is not defined in the
environment, $COMSPEC is used. Also, if an environment variable
named $MAKESHELL is defined, it takes precedence over both
$COMSPEC and $SHELL. Note that, unlike Unix, $SHELL in the
environment *is* used to set the shell (since on MSDOS, it's
unlikely that the interactive shell will not be suitable for
Makefile processing).
The bottom line is that you can now write Makefiles where some
of the targets require a real (i.e. Unix-like) shell, which will
nevertheless work when such shell is not available (provided, of
course, that the commands which should always work, don't
require such a shell). More important, you can convert Unix
Makefiles to MSDOS and leave the line which sets the shell
intact, so that people who do have Unixy shell could use it for
targets which aren't converted to DOS (like 'install' and
'uninstall', for example).
3. Default directories.
GNU Make knows about standard directories where it searches for
library and include files mentioned in the Makefile. Since
MSDOS machines don't have standard places for these, this port
will search ${DJDIR}/lib and ${DJDIR}/include respectively.
$DJDIR is defined automatically by the DJGPP startup code as the
root of the DJGPP installation tree (unless you've tampered with
the DJGPP.ENV file). This should provide reasonable default
values, unless you moved parts of DJGPP to other directories.
4. Letter-case in filenames.
If you run Make on Windows 9x, you should be aware of the
letter-case issue. Make is internally case-sensitive, but all
file operations are case-insensitive on Windows 9x, so
e.g. files 'FAQ', 'faq' and 'Faq' all refer to the same file, as
far as Windows is concerned. The underlying DJGPP C library
functions honor the letter-case of the filenames they get from
the OS, except that by default, they down-case 8+3 DOS filenames
which are stored in upper case in the directory and would break
many Makefiles otherwise. (The details of which filenames are
converted to lower case are explained in the DJGPP libc docs,
under the '_preserve_fncase' and '_lfn_gen_short_fname'
functions, but as a thumb rule, any filename that is stored in
upper case in the directory, is a valid DOS 8+3 filename and
doesn't include characters invalid on MSDOS FAT filesystems,
will be automatically down-cased.) User reports that I have
indicate that this default behavior is generally what you'd
expect; however, your input is most welcome.
In any case, if you hit a situation where you must force Make to
get the 8+3 DOS filenames in upper case, set FNCASE=y in the
environment or in the Makefile.
5. DOS-style pathnames.
There are a lot of places throughout the program sources which
make implicit assumptions about the pathname syntax. In
particular, the directories are assumed to be separated by '/',
and any pathname which doesn't begin with a '/' is assumed to be
relative to the current directory. This port attempts to
support DOS-style pathnames which might include the drive letter
and use backslashes instead of forward slashes. However, this
support is not complete; I feel that pursuing this support too
far might break some more important features, particularly if
you use a Unix-style shell (where a backslash is a quote
character). I only consider support of backslashes desirable
because some Makefiles invoke non-DJGPP programs which don't
understand forward slashes. A notable example of such programs
is the standard programs which come with MSDOS. Otherwise, you
are advised to stay away from backslashes whenever possible. In
particular, filename globbing won't work on pathnames with
backslashes, because the GNU 'glob' library doesn't support them
(backslash is special in filename wildcards, and I didn't want
to break that).
One feature which *does* work with backslashes is the filename-
related built-in functions such as $(dir), $(notdir), etc.
Drive letters in pathnames are also fully supported.
Bug reports:
-----------
Bugs that are clearly related to the MSDOS/DJGPP port should be
reported first on the comp.os.msdos.djgpp news group (if you cannot
post to Usenet groups, write to the DJGPP mailing list,
<djgpp@delorie.com>, which is an email gateway into the above news
group). For other bugs, please follow the procedure explained in
the "Bugs" chapter of the Info docs. If you don't have an Info
reader, look up that chapter in the 'make.i1' file with any text
browser/editor.
Enjoy,

Port of GNU Make to OS/2.
Features of GNU Make that do not work under OS/2:
- remote job execution
- dynamic load balancing
Special features of the OS/2 version:
Due to the fact that some people might want to use sh syntax in
Makefiles while others might want to use OS/2's native shell cmd.exe,
GNU Make supports both shell types. The following list defines the order
that is used to determine the shell:
1. The shell specified by the environment variable MAKESHELL.
2. The shell specified by the SHELL variable within a Makefile. Like
Unix, SHELL is NOT taken from the environment.
3. The shell specified by the COMSPEC environment variable.
4. The shell specified by the OS2_SHELL environment variable.
5. If none of the above is defined /bin/sh is used as default. This
happens e.g. in the make testsuite.
Note: - Points 3 and 4 can be turned off at compile time by adding
-DNO_CMD_DEFAULT to the CPPFLAGS.
- DOS support is not tested for EMX and therefore might not work.
- The UNIXROOT environment variable is supported to find /bin/sh
if it is not on the current drive.
COMPILATION OF GNU MAKE FOR OS/2:
I. ***** SPECIAL OPTIONS *****
- At compile time you can turn off that cmd is used as default shell
(but only /bin/sh). Simply set CPPFLAGS="-DNO_CMD_DEFAULT" and make
will not use cmd unless you cause it to do so by setting MAKESHELL to
cmd or by specifying SHELL=cmd in your Makefile.
- At compile time you can set CPPFLAGS="-DNO_CHDIR2" to turn off that
GNU Make prints drive letters. This is necessary if you want to run
the testsuite.
II. ***** REQUIREMENTS FOR THE COMPILATION *****
A standard Unix like build environment:
- sh compatible shell (ksh, bash, ash, but tested only with pdksh 5.2.14
release 2)
If you use pdksh it is recommended to update to 5.2.14 release 2. Older
versions may not work! You can get this version at
https://www.math.ohio-state.edu/~ilya/software/os2/pdksh-5.2.14-bin-2.zip
- GNU file utilities (make sure that install.exe from the file utilities
is in front of your PATH before X:\OS2\INSTALL\INSTALL.EXE. I recommend
also to change the filename to ginstall.exe instead of install.exe
to avoid confusion with X:\OS2\INSTALL\INSTALL.EXE)
- GNU shell utilities
- GNU text utilities
- gawk
- grep
- sed
- GNU Make 3.79.1 (special OS/2 patched version) or higher
- perl 5.005 or higher
- GNU texinfo (you can use 3.1 (gnuinfo.zip), but I recommend 4.0)
If you want to recreate the configuration files (developers only!)
you need also: GNU m4 1.4, autoconf 2.59, automake 1.9.6 (or compatible)
III. ***** COMPILATION AND INSTALLATION *****
a) ** Developers only - Everyone else should skip this section **
To recreate the configuration files use:
export EMXSHELL=ksh
aclocal -I m4
automake
autoconf
autoheader
b) Installation into x:/usr
Note: Although it is possible to compile make using "./configure",
"make", "make install" this is not recommended. In particular,
you must ALWAYS use LDFLAGS="-Zstack 0x6000" because the default
stack size is far to small and make will not work properly!
Recommended environment variables and installation options:
export ac_executable_extensions=".exe"
export CPPFLAGS="-D__ST_MT_ERRNO__"
export CFLAGS="-O2 -Zomf -Zmt"
export LDFLAGS="-Zcrtdll -Zlinker /exepack:2 -Zlinker /pm:vio -Zstack 0x6000"
export RANLIB="echo"
./configure --prefix=x:/usr --infodir=x:/usr/share/info --mandir=x:/usr/share/man
make AR=emxomfar
make install
Note: If you use gcc 2.9.x I recommend to set also LIBS="-lgcc"
Note: You can add -DNO_CMD_DEFAULT and -DNO_CHDIR2 to CPPFLAGS.
See section I. for details.
Note: If you use Open Watcom Linker instead of IBM Linker, remove
'-Zlinker /exepack:2' from LDFLAGS.
IV. ***** NLS support *****
GNU Make has NLS (National Language Support), with the following
caveats:
a) It will only work with GNU gettext, and
b) GNU gettext support is not included in the GNU Make package.
Therefore, if you wish to enable the internationalization features of
GNU Make you must install GNU gettext on your system before configuring
GNU Make.
You can choose the languages to be installed. To install support for
English, German and French only enter:
export LINGUAS="en de fr"
If you don't specify LINGUAS all languages are installed.
If you don't want NLS support (English only) use the option
--disable-nls for the configure script. Note if GNU gettext is not
installed then NLS will not be enabled regardless of this flag.
V. ***** Running the make test suite *****
To run the included make test suite you have to set
CPPFLAGS="-D__ST_MT_ERRNO__ -DNO_CMD_DEFAULT -DNO_CHDIR2"
before you compile make. This is due to some restrictions of the
testsuite itself. -DNO_CMD_DEFAULT causes make to use /bin/sh as default
shell in every case. Normally you could simply set MAKESHELL="/bin/sh"
to do this but the testsuite ignores the environment. -DNO_CHDIR2 causes
make not to use drive letters for directory names (i.e. _chdir2() and
_getcwd2() are NOT used). The testsuite interprets the whole output of
make, especially statements like make[1]: Entering directory
'C:/somewhere/make-3.79.1/tests' where the testsuite does not expect the
drive letter. This would be interpreted as an error even if there is
none.
To run the testsuite do the following:
export CPPFLAGS="-D__ST_MT_ERRNO__ -DNO_CMD_DEFAULT -DNO_CHDIR2"
export CFLAGS="-Zomf -O2 -Zmt"
export LDFLAGS="-Zcrtdll -s -Zlinker /exepack:2 -Zlinker /pm:vio -Zstack 0x6000"
export RANLIB="echo"
./configure --prefix=x:/usr --disable-nls
make AR=emxomfar
make check
All tests should work fine with the exception of one of the "INCLUDE_DIRS"
tests which will fail if your /usr/include directory is on a drive different
from the make source tree.

Overview: -*-text-mode-*-
---------
This version of GNU Make has been tested on:
OpenVMS V8.3/V8.4 (Alpha) and V8.4 (Integrity) AND V7.3 (VAX)
This version of GNU Make is intended to be run from DCL to run
make scripts with a special syntax that is described below. It
likely will not be able to run unmodified Unix makefiles.
There is an older implementation of GNU Make that was ported to GNV.
Work is now in progress to merge that port to get a single version
of GNU Make available. When that merge is done, GNU Make will auto
detect that it is running under a POSIX shell and then operate as close to
GNU Make on Unix as possible.
The descriptions below are for running GNU Make from DCL or equivalent.
Recipe differences:
-------------------
GNU Make for OpenVMS can not currently run native Unix make files because of
differences in the implementation.
I am trying to document the current behavior in this section. This is based
on the information in the file NEWS. and running the test suite.
TODO: More tests are needed to validate and demonstrate the OpenVMS
expected behavior.
In some cases the older behavior of GNU Make when run from DCL is not
compatible with standard makefile behavior.
This behavior can be changed when running GNU Make from DCL by setting
either DCL symbols or logical names of the format GNV$. The settings
are enabled with a string starting with one of '1', 'T', or 'E' for "1",
"TRUE", or "ENABLE". They are disabled with a '0', 'F', or 'D' for "1",
"FALSE", or "DISABLE". If they are not explicitly set to one of these
values, then they will be set to their default values.
The value of the setting DECC$FILENAME_UNIX_REPORT or
DECC$FILENAME_UNIX_ONLY will now cause the $(dir x) function to return
'./' or '[]' as appropriate.
The name GNV$MAKE_OLD_VMS when enabled will cause GNU Make to behave as
much as the older method as can be done with out disabling VMS features.
When it is disabled GNU Make have the new behavior which more closely
matches Unix Make behavior.
The default is currently the old behavior when running GNU Make from DCL.
In the future this may change. When running make from GNV Bash the new
behavior is the default.
This is a global setting that sets the default behavior for several other
options that can be individually changed. Many of the individual settings
are to make it so that the self tests for GNU Make need less VMS specific
modifications.
The name GNV$MAKE_COMMA when enabled will cause GNU Make to expect a comma
for a path separator and use a comma for the separator for a list of files.
When disabled, it will cause GNU Make to use a colon for a path separator
and a space for the separator for a list of files. The default is to be
enabled if the GNU Make is set to the older behavior.
The name GNV$MAKE_SHELL_SIM when enabled will cause GNU Make to try to
simulate a POSIX shell more closely. The following behaviors occur:
* Single quotes are converted to double quotes and any double
quotes inside of them are doubled. No environment variable expansion
is simulated.
* A exit command status will be converted to a POSIX Exit
where 0 is success and non-zero is failure.
* The $ character will cause environment variable expansion.
* Environment variables can be set on the command line before a command.
VMS generally uses logical name search lists instead of path variables
where the resolution is handled by VMS independent of the program. Which
means that it is likely that nothing will notice if the default path
specifier is changed in the future.
Currently the built in VMS specific macros and recipes depend on the comma
being used as a file list separator.
TODO: Remove this dependency as other functions in GNU Make depend on a
space being used as a separator.
The format for recipes are a combination of Unix macros, a subset of
simulated UNIX commands, some shell emulation, and OpenVMS commands.
This makes the resulting makefiles unique to the OpenVMS port of GNU Make.
If you are creating a OpenVMS specific makefile from scratch, you should also
look at MMK (Madgoat Make) available at https://github.com/endlesssoftware/mmk
MMK uses full OpenVMS syntax and a persistent sub-process is used for the
recipe lines, allowing multiple line rules.
The default makefile search order is "makefile.vms", "gnumakefile",
"makefile". TODO: See if that lookup is case sensitive.
When Make is invoked from DCL, it will create a foreign command
using the name of executable image, with any facility prefix removed,
for the duration of the make program, so it can be used internally
to recursively run make(). The macro MAKE_COMMAND will be set to
this foreign command.
When make is launched from an exec*() command from a C program,
the foreign command is not created. The macro MAKE_COMMAND will be
set to the actual command passed as argv[0] to the exec*() function.
If the DCL symbol or logical name GNV$MAKE_USE_MCR exists, then
the macro MAKE_COMMAND will be set to be an "MCR" command with the
absolute path used by DCL to launch make. The foreign command
will not be created.
The macro MAKE is set to be the same value as the macro MAKE_COMMAND
on all platforms.
Each recipe command is normally run as a separate spawned processes,
except for the cases documented below where a temporary DCL command
file may be used.
BUG: Testing has shown that the commands in the temporary command files
are not always created properly. This issue is still under investigation.
Any macros marked as exported are temporarily created as DCL symbols
for child images to use. DCL symbol substitution is not done with these
commands.
Untested: Symbol substitution.
When a temporary DCL command file is used, DCL symbol substitution
will work.
For VMS 7.3-1 and earlier, command lines are limited to 255 characters
or 1024 characters in a command file.
For VMS 7.3-2 and later, command lines are limited to 4059 characters
or 8192 characters in a command file.
VMS limits each token of a command line to 256 characters, and limits
a command line to 127 tokens.
Command lines above the limit length are written to a command file
in sys$scratch:.
In order to handle Unix style extensions to VMS DCL, GNU Make has
parsed the recipe commands and them modified them as needed. The
parser has been re-written to resolve numerous bugs in handling
valid VMS syntax and potential buffer overruns.
The new parser may need whitespace characters where DCL does not require
it, and also may require that quotes are matched were DCL forgives if
they are not. There is a small chance that existing VMS specific makefiles
will be affected.
The '<', '>' was previously implemented using command files. Now
GNU Make will check to see if the is already a VMS "PIPE" command and
if it is not, will convert the command to a VMS "PIPE" command.
The '>>' redirection has been implemented by using a temporary command file.
This will be described later.
The DCL symbol or logical name GNV$MAKE_USE_CMD_FILE when set to a
string starting with one of '1','T', or 'E' for "1", "TRUE", or "ENABLE",
then temporary DCL command files are always used for running commands.
Some recipe strings with embedded new lines will not be handled correctly
when a command file is used.
GNU Make generally does text comparisons for the targets and sources. The
make program itself can handle either Unix or OpenVMS format filenames, but
normally does not do any conversions from one format to another.
TODO: The OpenVMS format syntax handling is incomplete.
TODO: ODS-5 EFS support is missing.
BUG: The internal routines to convert filenames to and from OpenVMS format
do not work correctly.
Note: In the examples below, line continuations such as a backslash may have
been added to make the examples easier to read in this format.
BUG: That feature does not completely work at this time.
Since the OpenVMS utilities generally expect OpenVMS format paths, you will
usually have to use OpenVMS format paths for rules and targets.
BUG: Relative OpenVMS paths may not work in targets, especially combined
with vpaths. This is because GNU Make will just concatenate the directories
as it does on Unix.
The variables $^ and $@ separate files with commas instead of spaces.
This is controlled by the name GNV$MAKE_COMMA as documented in the
previous section.
While this may seem the natural thing to do with OpenVMS, it actually
causes problems when trying to use other make functions that expect the
files to be separated by spaces. If you run into this, you need the
following workaround to convert the output.
TODO: Look at have the $^ and $@ use spaces like on Unix and have
and easy to use function to do the conversions and have the built
in OpenVMS specific recipes and macros use it.
Example:
comma := ,
empty :=
space := $(empty) $(empty)
foo: $(addsuffix .3,$(subs $(comma),$(space),$^)
Makefile variables are looked up in the current environment. You can set
symbols or logicals in DCL and evaluate them in the Makefile via
$(<name-of-symbol-or-logical>). Variables defined in the Makefile
override OpenVMS symbols/logicals.
OpenVMS logical and symbols names show up as "environment" using the
origin function. when the "-e" option is specified, the origin function
shows them as "environment override". On POSIX the test scripts indicate
that they should show up just as "environment".
When GNU Make reads in a symbol or logical name into the environment, it
converts any dollar signs found to double dollar signs for convenience in
using DCL symbols and logical names in recipes. When GNU Make exports a
DCL symbol for a child process, if the first dollar sign found is followed
by second dollar sign, then all double dollar signs will be converted to
single dollar signs.
The variable $(ARCH) is predefined as IA64, ALPHA or VAX respectively.
Makefiles for different OpenVMS systems can now be written by checking
$(ARCH). Since IA64 and ALPHA are similar, usually just a check for
VAX or not VAX is sufficient.
You may have to update makefiles that assume VAX if not ALPHA.
ifeq ($(ARCH),VAX)
$(ECHO) "On the VAX"
else
$(ECHO) "On the ALPHA or IA64"
endif
Empty commands are handled correctly and don't end in a new DCL process.
The exit command needs to have OpenVMS exit codes. To pass a POSIX code
back to the make script, you need to encode it by multiplying it by 8
and then adding %x1035a002 for a failure code and %x1035a001 for a
success. Make will interpret any POSIX code other than 0 as a failure.
TODO: Add an option have simulate POSIX exit commands in recipes.
Lexical functions can be used in pipes to simulate shell file test rules.
Example:
POSIX:
b : c ; [ -f $@ ] || echo >> $@
OpenVMS:
b : c ; if f$$search("$@") then pipe open/append xx $@ ; write xx "" ; close xx
You can also use pipes and turning messages off to silently test for a
failure.
x = %x1035a00a
%.b : %.c
<tab>pipe set mess/nofac/noiden/nosev/notext ; type $^/output=$@ || exit $(x)
Runtime issues:
The OpenVMS C Runtime has a convention for encoding a POSIX exit status into
to OpenVMS exit codes. These status codes will have the hex value of
0x35a000. OpenVMS exit code may also have a hex value of %x10000000 set on
them. This is a flag to tell DCL not to write out the exit code.
To convert an OpenVMS encoded POSIX exit status code to the original code
You subtract %x35a000 and any flags from the OpenVMS code and divide it by 8.
WARNING: Backward-incompatibility!
The make program exit now returns the same encoded POSIX exit code as on
Unix. Previous versions returned the OpenVMS exit status code if that is what
caused the recipe to fail.
TODO: Provide a way for scripts calling make to obtain that OpenVMS status
code.
Make internally has two error codes, MAKE_FAILURE and MAKE_TROUBLE. These
will have the error "-E-" severity set on exit.
MAKE_TROUBLE is returned only if the option "-q" or "--question" is used and
has a POSIX value of 1 and an OpenVMS status of %x1035a00a.
MAKE_FAILURE has a POSIX value of 2 and an OpenVMS status of %x1035a012.
Output from GNU Make may have single quotes around some values where on
other platforms it does not. Also output that would be in double quotes
on some platforms may show up as single quotes on VMS.
There may be extra blank lines in the output on VMS.
https://savannah.gnu.org/bugs/?func=detailitem&item_id=41760
There may be a "Waiting for unfinished jobs..." show up in the output.
Error messages generated by Make or Unix utilities may slightly vary from
POSIX platforms. Typically the case may be different.
When make deletes files, on POSIX platforms it writes out 'rm' and the list
of files. On VMS, only the files are written out, one per line.
TODO: VMS
There may be extra leading white space or additional or missing whitespace
in the output of recipes.
GNU Make uses sys$scratch: for the tempfiles that it creates.
The OpenVMS CRTL library maps /tmp to sys$scratch if the TMP: logical name
does not exist. As the CRTL may use both sys$scratch: and /tmp internally,
if you define the TMP logical name to be different than SYS$SCRATCH:,
you may end up with only some temporary files in TMP: and some in SYS$SCRATCH:
The default include directory for including other makefiles is
SYS$SYSROOT:[SYSLIB] (I don't remember why I didn't just use
SYS$LIBRARY: instead; maybe it wouldn't work that way).
TODO: A better default may be desired.
If the device for a file in a recipe does not exist, on OpenVMS an error
message of "stat: <file>: no such device or address" will be output.
Make ignores success, informational, or warning errors (-S-, -I-, or
-W-). But it will stop on -E- and -F- errors. (unless you do something
to override this in your makefile, or whatever).
Unix compatibility features:
----------------------------
If the command 'echo' is seen, any single quotes on the line will be
converted to double quotes.
The variable $(CD) is implemented as a built in Change Directory
command. This invokes the 'builtin_cd' Executing a 'set default'
recipe doesn't do the trick, since it only affects the sub-process
spawned for that command.
The 'builtin_cd' is generally expected to be on its own line.
The 'builtin_cd' either from the expansion of $(CD) or directly
put in a recipe line will be executed before any other commands in
that recipe line. DCL parameter substitution will not work for the
'builtin_cd' command.
Putting a 'builtin_cd' in a pipeline or an IF-THEN line should not be
done because the 'builtin_cd' is always executed
and executed first. The directory change is persistent.
Unix shell style I/O redirection is supported. You can now write lines like:
"<tab>mcr sys$disk:[]program.exe < input.txt > output.txt &> error.txt"
POSIX shells have ":" as a null command. These are now handled.
https://savannah.gnu.org/bugs/index.php?41761
A note on appending the redirected output. A simple mechanism is
implemented to make ">>" work in action lines. In OpenVMS there is no simple
feature like ">>" to have DCL command or program output redirected and
appended to a file. GNU Make for OpenVMS implements the redirection
of ">>" by using a command procedure.
The current algorithm creates the output file if it does not exist and
then uses the DCL open/append to extend it. SYS$OUTPUT is then directed
to that file.
The implementation supports only one redirected append output to a file
and that redirection is done before any other commands in that line
are executed, so it redirects all output for that command.
The older implementation wrote the output to a temporary file in
in sys$scratch: and then attempted to append the file to the existing file.
The temporary file names looked like "CMDxxxxx.". Any time the created
command procedure can not complete, this happens. Pressing CTRL+Y to
abort make is one case.
In case of CTRL+Y the associated command procedure is left in SYS$SCRATCH:.
The command procedures will be named gnv$make_cmd*.com.
The CtrlY handler now uses $delprc to delete all children. This way also
actions with DCL commands will be stopped. As before the CtrlY handler
then sends SIGQUIT to itself, which is handled in common code.
Temporary command files are now deleted in the OpenVMS child termination
handler. That deletes them even if a CTRL+C was pressed.
TODO: Does the previous section about >> leaving files still apply?
The behavior of pressing CTRL+C is not changed. It still has only an effect,
after the current action is terminated. If that doesn't happen or takes too
long, CTRL+Y should be used instead.
Build Options:
Added support to have case sensitive targets and dependencies but to
still use case blind file names. This is especially useful for Java
makefiles on VMS:
<TAB>.SUFFIXES :
<TAB>.SUFFIXES : .class .java
<TAB>.java.class :
<TAB><TAB>javac "$<"
<TAB>HelloWorld.class : HelloWorld.java
A new macro WANT_CASE_SENSITIVE_TARGETS in config.h-vms was introduced.
It needs to be enabled to get this feature; default is disabled.
TODO: This should be a run-time setting based on if the process
has been set to case sensitive.
Unimplemented functionality:
The new feature "Loadable objects" is not yet supported. If you need it,
please send a change request or submit a bug report.
The new option --output-sync (-O) is accepted but has no effect: GNU Make
for OpenVMS does not support running multiple commands simultaneously.
Self test failures and todos:
-----------------------------
The test harness can not handle testing some of the VMS specific modes
because of the features needed for to be set for the Perl to run.
Need to find a way to set the VMS features before running make as a
child.
GNU Make was not currently translating the OpenVMS encoded POSIX values
returned to it back to the POSIX values. I have temporarily modified the
Perl test script to compensate for it. This should be being handled
internally to Make.
TODO: Verify and update the Perl test script.
The features/parallelism test was failing. OpenVMS is executing the rules
in sequence not in parallel as this feature was not implemented.
GNU Make on VMS no longer claims it is implemented.
TODO: Implement it.
Symlink support is not present. Symlinks are supported by OpenVMS 8.3 and
later.
Error messages should be suppressed with the "-" at the beginning of a line.
On openVMS they were showing up. TODO: Is this still an issue?
The internal vmsify and unixify OpenVMS to/from UNIX are not handling logical
names correctly.
Build instructions:
-------------------
Don't use the HP C V7.2-001 compiler, which has an incompatible change
how __STDC__ is defined. This results at least in compile time warnings.
Make a 1st version
$ @makefile.com ! ignore any compiler and/or linker warning
$ copy make.exe 1st-make.exe
Use the 1st version to generate a 2nd version as a test.
$ mc sys$disk:[]1st-make clean ! ignore any file not found messages
$ mc sys$disk:[]1st-make
Verify your 2nd version by building Make again.
$ copy make.exe 2nd-make.exe
$ mc sys$disk:[]2nd-make clean
$ mc sys$disk:[]2nd-make
Running the tests:
------------------
Running the tests on OpenVMS requires the following software to be installed
as most of the tests are Unix oriented.
* Perl 5.18 or later.
https://sourceforge.net/projects/vmsperlkit/files/
* GNV 2.1.3 + Updates including a minimum of:
* Bash 4.3.30
* ld_tools 3.0.2
* coreutils 8.21
https://sourceforge.net/p/gnv/wiki/InstallingGNVPackages/
https://sourceforge.net/projects/gnv/files/
As the test scripts need to create some foreign commands that persist
after the test is run, it is recommend that either you use a sub-process or
a dedicated login to run the tests.
To get detailed information for running the tests:
$ set default [.tests]
$ @run_make_tests help
Running the script with no parameters will run all the tests.
After the the test script has been run once in a session, assuming
that you built make in sys$disk:[make], you can redefined the
"bin" logical name as follows:
$ define bin sys$disk:[make],gnv$gnu:[bin]
Then you can use Perl to run the scripts.
$ perl run_make_tests.pl

This version of GNU Make has been tested on:
Microsoft Windows 2000/XP/2003/Vista/7/8/10/11
It has also been used on Windows 95/98/NT, and on OS/2.
It builds with the MinGW port of GCC (tested with GCC 3.4.2, 4.8.1,
and 4.9.3).
It also builds with MSVC 2.x, 4.x, 5.x, 6.x, 2005, 2008, 2010, 2012,
2013, and 2015 as well as with .NET 7.x and .NET 2003.
Building with Guile is supported (tested with Guile 2.0.x). To build
with Guile, you will need, in addition to Guile itself, its dependency
libraries and the pkg-config program. The latter is used to figure out
which compilation and link switches and libraries need to be mentioned
on the compiler command lines to correctly link with Guile. A Windows
port of pkg-config can be found on ezwinports site:
https://sourceforge.net/projects/ezwinports/
The libraries on which Guile depends can vary depending on your
version and build of Guile. At the very least, the Boehm's GC library
will be needed, and typically also GNU MP, libffi, libunistring, and
libtool's libltdl. Whoever built the port of Guile you have should
also provide you with these dependencies or a URL where to download
them. A precompiled 32-bit Windows build of Guile is available from
the ezwinports site mentioned above.
The Windows port of GNU Make is maintained jointly by various people.
It was originally made by Rob Tulloh.
It is currently maintained by Eli Zaretskii.
Do this first, regardless of the build method you choose:
---------------------------------------------------------
1. If you have special requirements, edit config.h.W32 to your liking
(especially the shell-related defines, or HAVE_CASE_INSENSITIVE_FS which
corresponds to './configure --enable-case-insensitive-file-system'). We
don't recommend to define HAVE_CASE_INSENSITIVE_FS, but you may wish to
consider that if you have a lot of files whose names are in upper case,
while Makefile rules are written for lower-case versions.
If you don't have special requirements no changes are needed.
Building with (MinGW-)GCC using build_w32.bat
---------------------------------------------
2. Open a W32 command prompt for your installed (MinGW-)GCC, setup a
correct PATH and other environment variables for it, then execute ...
.\build_w32.bat gcc
This produces gnumake.exe in the GccRel directory.
If you want a version of GNU Make built with debugging enabled,
add the --debug option. Output goes into the GccDebug directory.
The batch file will probe for Guile installation, and will build
gnumake.exe with Guile if it finds it. If you have Guile
installed, but want to build Make without Guile support, type
.\build_w32.bat --without-guile gcc
Building with (MSVC++-)cl using build_w32.bat
---------------------------------------------
2. Open a command shell, then execute ...
.\build_w32.bat
This produces a 64bit Release build of gnumake.exe in .\WinRel, using
the compiler found on the %Path%. If no compiler is found, the batch
file will probe your system and choose the newest MSVC version it can
find.
If you want a 32bit version of GNU Make, add the --x86 option.
If you want a Debug build of GNU Make, add the --debug option. Output
will go into the .\WinDebug directory.
The batch file will probe for Guile installation, and will build
gnumake.exe with Guile if it finds it. If Guile is installed,
but you prefer to build GNU Make without Guile support, add the
--without-guile option.
Building with (MinGW-)GCC using GNU Make
----------------------------------------
2. If you already have a version of GNU Make available you can use it
to build this version. Open a W32 command prompt for your installed
(MinGW-)GCC, setup a correct PATH and other environment variables
for it, then execute ...
make -f Basic.mk TOOLCHAIN=gcc
This produces GccRel\gnumake.exe.
If you want a version of GNU Make built with debugging enabled,
add the TARGET_TYPE=debug option:
make -f Basic.mk TOOLCHAIN=gcc TARGET_TYPE=debug
The makefile doesn't support Guile integration. Use build_w32.bat
if you want to build with Guile support.
Building with (MSVC++-)cl using GNU Make
----------------------------------------
2. If you already have a version of GNU Make available you can use it
to build this version. Open a W32 command prompt for your installed
(MSVC++-)cl, setup a correct PATH and other environment variables
for it (usually via executing vcvars32.bat or vsvars32.bat from the
cl-installation, or using a corresponding start menu entry from the
cl-installation), then execute ...
make -f Basic.mk
This produces an optimized WinRel/gnumake.exe.
If you want a version of GNU Make built with debugging enabled,
add the TARGET_TYPE=debug option:
make -f Basic.mk TARGET_TYPE=debug
The makefile doesn't support Guile integration. Use build_w32.bat
if you want to build with Guile support.
Running the test suite
----------------------
3. You will need an installation of Perl. Be sure to use a relatively
modern version: older versions will sometimes throw spurious errors.
To run the suite after building using GNU Make, use:
make -f Basic.mk check
Alternatively if you'd like to run tests by hand, use:
cd tests
.\run_make_tests.bat -make <path-to-make>
I've found <path-to-make> seems to want forward-slashes in the path.
For example if building with .\build_w32.bat non-debug, use:
cd tests
.\run_make_tests.bat -make ../WinRel/gnumake.exe
I've tested this with the MSYS2 shell and POSIX tools installation
that you get by installing Git for Windows.
-------------------
-- Notes/Caveats --
-------------------
GNU Make on Windows 32-bit platforms:
This version of make is ported natively to Windows32 platforms
(Windows NT 3.51, Windows NT 4.0, Windows 2000, Windows XP,
Windows 95, and Windows 98). It does not rely on any 3rd party
software or add-on packages for building. The only thing
needed is a Windows compiler. Two compilers supported
officially are the MinGW port of GNU GCC, and the various
versions of the Microsoft C compiler.
Do not confuse this port of GNU Make with other Windows32 projects
which provide a GNU Make binary. These are separate projects
and are not connected to this port effort.
GNU Make and sh.exe:
This port prefers if you have a working sh.exe somewhere on
your system. If you don't have sh.exe, the port falls back to
MSDOS mode for launching programs (via a batch file). The
MSDOS mode style execution has not been tested that carefully
though (The author uses GNU bash as sh.exe).
There are very few true ports of Bourne shell for NT right now.
There is a version of GNU bash available from Cygnus "Cygwin"
porting effort (https://www.cygwin.com/).
Other possibilities are the MKS version of sh.exe, or building
your own with a package like NutCracker (DataFocus) or Portage
(Consensys). Also MinGW includes sh.
GNU Make and brain-dead shells (BATCH_MODE_ONLY_SHELL):
Some versions of Bourne shell do not behave well when invoked
as 'sh -c' from CreateProcess(). The main problem is they seem
to have a hard time handling quoted strings correctly. This can
be circumvented by writing commands to be executed to a batch
file and then executing the command by calling 'sh file'.
To work around this difficulty, this version of make supports
a batch mode. When BATCH_MODE_ONLY_SHELL is defined at compile
time, make forces all command lines to be executed via script
files instead of by command line. In this mode you must have a
working sh.exe in order to use parallel builds (-j).
A native Windows32 system with no Bourne shell will also run
in batch mode. All command lines will be put into batch files
and executed via $(COMSPEC) (%COMSPEC%). However, parallel
builds ARE supported with Windows shells (cmd.exe and
command.com). See the next section about some peculiarities
of parallel builds on Windows.
Support for parallel builds
Parallel builds (-jN) are supported in this port. The number of
concurrent processes has a hard limit of 4095.
GNU Make and Cygnus GNU Windows32 tools:
Good news! Make now has native support for Cygwin sh. To enable,
define the HAVE_CYGWIN_SHELL in config.h and rebuild make
from scratch. This version of make tested with B20.1 of Cygwin.
Do not define BATCH_MODE_ONLY_SHELL if you use HAVE_CYGWIN_SHELL.
GNU Make and the MKS shell:
There is now semi-official support for the MKS shell. To turn this
support on, define HAVE_MKS_SHELL in the config.h.W32 before you
build make. Do not define BATCH_MODE_ONLY_SHELL if you turn
on HAVE_MKS_SHELL.
GNU Make handling of drive letters in pathnames (PATH, vpath, VPATH):
There is a caveat that should be noted with respect to handling
single character pathnames on Windows systems. When colon is
used in PATH variables, make tries to be smart about knowing when
you are using colon as a separator versus colon as a drive
letter. Unfortunately, something as simple as the string 'x:/'
could be interpreted 2 ways: (x and /) or (x:/).
Make chooses to interpret a letter plus colon (e.g. x:/) as a
drive letter pathname. If it is necessary to use single
character directories in paths (VPATH, vpath, Path, PATH), the
user must do one of two things:
a. Use semicolon as the separator to disambiguate colon. For
example use 'x;/' if you want to say 'x' and '/' are
separate components.
b. Qualify the directory name so that there is more than
one character in the path(s) used. For example, none
of these settings are ambiguous:
./x:./y
/some/path/x:/some/path/y
x:/some/path/x:x:/some/path/y
Please note that you are free to mix colon and semi-colon in the
specification of paths. Make is able to figure out the intended
result and convert the paths internally to the format needed
when interacting with the operating system, providing the path
is not within quotes, e.g. "x:/test/test.c".
You are encouraged to use colon as the separator character.
This should ease the pain of deciding how to handle various path
problems which exist between platforms. If colon is used on
both Unix and Windows systems, then no ifdef'ing will be
necessary in the makefile source.
Pathnames and white space:
Unlike Unix, Windows 95/NT systems encourage pathnames which
contain white space (e.g. C:\Program Files\). These sorts of
pathnames are valid on Unix too, but are never encouraged.
There is at least one place in make (VPATH/vpath handling) where
paths containing white space will simply not work. There may be
others too. I chose to not try and port make in such a way so
that these sorts of paths could be handled. I offer these
suggestions as workarounds:
1. Use 8.3 notation. i.e. "x:/long~1/", which is actually
"x:\longpathtest". Type "dir /x" to view these filenames
within the cmd.exe shell.
2. Rename the directory so it does not contain white space.
If you are unhappy with this choice, this is free software
and you are free to take a crack at making this work. The code
in w32/pathstuff.c and vpath.c would be the places to start.
Pathnames and Case insensitivity:
Unlike Unix, Windows 95/NT systems are case insensitive but case
preserving. For example if you tell the file system to create a
file named "Target", it will preserve the case. Subsequent access to
the file with other case permutations will succeed (i.e. opening a
file named "target" or "TARGET" will open the file "Target").
By default, GNU Make retains its case sensitivity when comparing
target names and existing files or directories. It can be
configured, however, into a case preserving and case insensitive
mode by adding a define for HAVE_CASE_INSENSITIVE_FS to
config.h.W32.
For example, the following makefile will create a file named
Target in the directory subdir which will subsequently be used
to satisfy the dependency of SUBDIR/DepTarget on SubDir/TARGET.
Without HAVE_CASE_INSENSITIVE_FS configured, the dependency link
will not be made:
subdir/Target:
touch $@
SUBDIR/DepTarget: SubDir/TARGET
cp $^ $@
Reliance on this behavior also eliminates the ability of GNU Make
to use case in comparison of matching rules. For example, it is
not possible to set up a C++ rule using %.C that is different
than a C rule using %.c. GNU Make will consider these to be the
same rule and will issue a warning.
SAMBA/NTFS/VFAT:
I have not had any success building the debug version of this
package using SAMBA as my file server. The reason seems to be
related to the way VC++ 4.0 changes the case name of the pdb
filename it is passed on the command line. It seems to change
the name always to to lower case. I contend that the VC++
compiler should not change the casename of files that are passed
as arguments on the command line. I don't think this was a
problem in MSVC 2.x, but I know it is a problem in MSVC 4.x.
The package builds fine on VFAT and NTFS filesystems.
Most all of the development I have done to date has been using
NTFS and long file names. I have not done any considerable work
under VFAT. VFAT users may wish to be aware that this port of
make does respect case sensitivity.
FAT:
Version 3.76 added support for FAT filesystems. Make works
around some difficulties with stat'ing of files and caching of
filenames and directories internally.
Bug reports:
Please submit bugs via the normal bug reporting mechanism which
is described in the GNU Make manual and the base README.

-*-indented-text-*-
GNU Make can utilize the Customs library, distributed with Pmake, to
provide builds distributed across multiple hosts.
In order to utilize this capability, you must first download and build
the Customs library. It is contained in the Pmake distribution, which
can be obtained at:
ftp://ftp.icsi.berkeley.edu/pub/ai/stolcke/software/
This integration was tested (superficially) with Pmake 2.1.33.
BUILDING CUSTOMS
----------------
First, build pmake and Customs. You need to build pmake first, because
Customs require pmake to build. Unfortunately, this is not trivial;
please see the pmake and Customs documentation for details. The best
place to look for instructions is in the pmake-2.1.33/INSTALL file.
Note that the 2.1.33 Pmake distribution comes with a set of patches to
GNU Make, distributed in the pmake-2.1.33/etc/gnumake/ directory. These
patches are based on GNU Make 3.75 (there are patches for earlier
versions of GNU Make, also). The parts of this patchfile which relate
directly to Customs support have already been incorporated into this
version of GNU Make, so you should _NOT_ apply the patch file.
However, there are a few non-Customs specific (as far as I could tell)
changes here which are not incorporated (for example, the modification
to try expanding -lfoo to libfoo.so). If you rely on these changes
you'll need to re-apply them by hand.
Install the Customs library and header files according to the
documentation. You should also install the man pages (contrary to
comments in the documentation, they weren't installed automatically for
me; I had to cd to the 'pmake-2.1.33/doc' directory and run 'pmake
install' there directly).
BUILDING GNU MAKE
-----------------
Once you've installed Customs, you can build GNU Make to use it. When
configuring GNU Make, merely use the '--with-customs=DIR' option.
Provide the directory containing the 'lib' and 'include/customs'
subdirectories as DIR. For example, if you installed the customs
library in /usr/local/lib and the headers in /usr/local/include/customs,
then you'd pass '--with-customs=/usr/local' as an option to configure.
Run make (or use build.sh) normally to build GNU Make as described in
the INSTALL file.
See the documentation for Customs for information on starting and
configuring Customs.
INVOKING CUSTOMS-IZED GNU MAKE
-----------------------------
One thing you should be aware of is that the default build environment
for Customs requires root permissions. Practically, this means that GNU
make must be installed setuid root to use Customs.
If you don't want to do this, you can build Customs such that root
permissions are not necessary. Andreas Stolcke <stolcke@speech.sri.com>
writes:
> pmake, gnumake or any other customs client program is not required to
> be suid root if customs was compiled WITHOUT the USE_RESERVED_PORTS

PROBLEMS
--------
SunOS 4.1.x:
The customs/sprite.h header file #includes the <malloc.h> header
files; this conflicts with GNU Make's configuration so you'll get a
compile error if you use GCC (or any other ANSI-capable C compiler).
I commented out the #include in sprite.h:107:
#if defined(sun) || defined(ultrix) || defined(hpux) || defined(sgi)
/* #include <malloc.h> */
#else
YMMV.

Obtaining Git Code
------------------
This seems redundant, since if you're reading this you most likely have
already performed this step; however, for completeness, you can obtain the GNU
make source code via Git from the FSF's Savannah project
<https://savannah.gnu.org/projects/make/>:
$ git clone git://git.savannah.gnu.org/make.git
Changes using Git
-----------------
If you do not have push privileges to the GNU Make Git repository, see the
README file section "Submitting Patches" for information.
If you have push privileges to the GNU Make Git repository keep this
information in mind:
Starting with GNU Make 4.0 we no longer keep a separate ChangeLog file in
source control. We use the Gnulib git-to-changelog conversion script to
convert the Git comments into ChangeLog-style entries for release. As a
result, please format your Git comments carefully so they will look clean
after conversion. In particular, each line of your comment will have a TAB
added before it so be sure your comment lines are not longer than 72
characters; prefer 70 or less. Please use standard ChangeLog formats for
your commit messages (sans the leading TAB of course).
Rule #1: Don't rewrite pushed history on master (no "git push --force").
Rule #2: Feel free to rewrite pushed history on personal branches.
Rule #3: Squash-merge or rebase + merge --ff-only, rather than merging from
personal branches into master.
Typical simple workflow might be:
* Edit files / make / make check
* Use "git status" and "git diff" to verify your changes
* Use "git add" to stage the changes you want to make
* Use "git commit" to commit the staged changes to your local repository
* Use "git pull -r" to accept new changes from the upstream repository
* Use "git push" to push your commits back to the upstream repository
For Emacs users, there are many options for Git integration but I strongly
recommend Magit: https://magit.vc/ It makes the workflow much clearer, and
has advanced features such as constructing multiple commits from various files
and even from different diff chunks in the same file. There is a video
available which helps a lot.
Coding Standards
----------------
GNU Make code adheres to the GNU Coding Standards. Please use only spaces and
no TAB characters in source code.
Additionally, GNU Make is a foundational bootstrap package for the GNU
project; as such it is conservative about language features it expects.
However, GNU Make does rely on the Gnulib portability library, and Gnulib
currently requires a ISO C99 compiler. So features in ISO C99 can be
assumed.
Building From Git for POSIX
---------------------------
To build GNU Make from Git on POSIX systems such as GNU/Linux, you will
need to install the following extra software:
* autoconf >= 2.69
* automake >= 1.16.1
* autopoint
* texinfo (for makeinfo)
* gettext
* pkg-config
* GCC
* GNU Make (POSIX make is not sufficient)
And any tools that those utilities require (GNU m4, etc.)
To run the tests you must install Perl.
To create dist files you will additionally need:
* lzip (to create tar.lz dist files)
* texlive (or some other TeX package)
GNU Make requires Gnulib to provide some facilities. If you want to maintain
a local installation of gnulib you can set GNULIB_SRCDIR to point to it.
Otherwise, ./bootstrap will obtain a clone for you.
Due to issues with gnulib's getloadavg, you must have automake 1.16.1 or
above. This version may not yet be available through GNU/Linux package
managers. If you need to install from source be sure to set ACLOCAL_PATH to
point to the pkg-config location (e.g., /usr/share/aclocal).
If you want to build from Git with a non-GCC compiler, add "MAKE_CFLAGS=" to
your make command line (or at least remove any flags your compiler does not
support).
When building from Git you must build in the source directory: "VPATH
builds" from remote directories are not supported. Once you've created
a distribution, of course, you can unpack it and do a VPATH build from
there.
After checking out the code, you will need to run the bootstrap script:
$ ./bootstrap
Alternatively you can just pull content from remote locations with:
$ ./bootstrap --pull
And/or just re-generate auto-generatable files with:
$ ./bootstrap --gen
(Running ./bootstrap does both in one step.)
At this point you have successfully brought your Git copy of the GNU
make source directory up to the point where it can be treated
more-or-less like the official package you would get from ftp.gnu.org.
That is, you can just run:
$ ./configure
$ make check
to build and test GNU Make.
NOTE! This method builds GNU Make in "maintainer mode". Make programs built
in this mode will be slower, possibly MUCH slower: there are various
sanity checks enabled. Further this mode assumes a modern GCC, GNU
libc, and well-formed system headers and enables a high level of
warnings AND enables -Werror to turn warnings into failures.
If you want to build from Git with "maintainer mode" disabled, add
"MAKE_MAINTAINER_MODE=" to the make command line. If you want to turn
off the extra warning flags, add "MAKE_CFLAGS=" to the make command
line. If you want to keep the warnings but not fail, add
"EXTRA_CFLAGS=-Wno-error" to the make command line.
For example:
$ ./configure
$ make check MAKE_MAINTAINER_MODE= MAKE_CFLAGS=
$ make install
Building From Git for Windows
-----------------------------
If you have a UNIX emulation like CYGWIN you can opt to run the general build
procedure above; it will work. Consult README.W32 for information on options
you might want to use when running ./configure.
If you can't or don't want to do that, then first run the .\bootstrap.bat
script to "prime" your Git workspace:
> .\bootstrap.bat
Next, follow the instructions in the README.W32 file.
Note, neither of these methods are tested regularly by the GNU Make
maintainers. Building for Windows from a distribution tarball IS tested
regularly.
NOTE! "Maintainer mode" (see above) IS ENABLED when building from Git using
the build_w32.bat file.
Debugging and Testing
---------------------
These instructions have been tested on GNU systems. I have no idea if they
work on non-GNU systems (Windows, MacOS, etc.)
* Alternate Configurations:
The maintMakefile has a rule for running configure with various different
options, with and without packages. Run:
make check-alt-config
* Valgrind:
You can run all tests under valgrind by passing the -memcheck option:
(cd tests && ./run_make_tests -make ../make -memcheck)
Note, this is slow! Also some tests will fail because of invoking valgrind.
* ASAN:
You can build with ASAN and run tests, like this:
make clean
make -j8 CFLAGS='-ggdb3 -fsanitize=address' LDFLAGS='-ggdb3 -fsanitize=address'
Then to check for corruption only but not memory leaks run:
ASAN_OPTIONS='detect_stack_after_use_return=true:detect_leaks=false' make check
To check for leaks too run:
make check
Note that ASAN is reporting many more errors than valgrind. I don't know
which one is wrong: I haven't looked at them closely.
Creating a Package
------------------
Once you have performed the above steps (including the configuration and
build) you can create a GNU Make package. This is very simple, just
run:
$ make dist-gzip
and, if you like:
$ make dist-lzip
Even better, you should run this:
$ make distcheck
Which will build both .gz and .lz package files, then unpack one into a
temporary location, try to build it and repack it, then verifying that
everything works, you get the same results, _and_ no extraneous files are
left over after the "distclean" rule.
This package can be unpacked and built to give a "normal" (non-maintainer
mode) result.
Steps to Release
----------------
Here are the things that need to be done (in more or less this order)
before making an official release. If something breaks such that you need to
change code, be sure to start over again sufficiently that everything is
consistent (that's why we don't finalize the Git tag, etc. until the end).
* Update the configure.ac file with the new release number.
* Update the EDITION value in the doc/make.texi file.
* Update the doc/make.1 file with the release date.
* Update the NEWS file with the release number and date.
* Ensure the Savannah bug list URL in the NEWS file uses the correct
"Fixed Release" ID number.
* Run "make distcheck" to be sure it all works.
* Run "make check-alt-config" to be sure alternative configurations work
* run "make tag-release" to create a Git tag for the release
* Push everything:
git push --tags origin master
The safest thing is to create an entirely new repository and build the final
package from there:
git clone git://git.savannah.gnu.org/make.git make-release
cd make-release
If you don't want to create a new repository then run "git clean -fdx".
Then:
./bootstrap
./configure
make distcheck
Perform test builds on whichever systems you have access to.
Use a previous announcement as a template to create an announcement in a text
file then sign it with GPG:
gpg --clearsign <announcement.txt>
Or, use your mail client's PGP/GPG signing capabilities.
NOTE! In order to publish a package on the FSF FTP site you need to have my
GPG private key, and my passphrase to unlock it.
Depending on your distribution (whether GnuPG is integrated with your
keyring etc.) the upload operation will either pop up a window asking
for the GPG key passphrase one time, or else it will use the CLI to ask
for the GPG passphrase _THREE_ times. Sigh.
Publishing a Release Candidate
------------------------------
Usually I publish one or two release candidates for people to test before
making an official release. Release candidates use a GNU numbering scheme,
which add a ".9x" release number to the PREVIOUS major release. So the first
release candidate for GNU Make 4.4 would be GNU Make 4.3.90, the second
release candidate would be 4.3.91, etc.
Upload a release candidate using:
make upload-alpha
Announce a release candidate to these mailing lists:
To: bug-make@gnu.org
BCC: help-make@gnu.org, make-w32@gnu.org, make-alpha@gnu.org
You will have to approve the BCC's on the mailing list admin sites. Send
separate copies to (don't use CC as replies will go to these lists):
* coordinator@translationproject.org
* platform-testers@gnu.org
Publishing a Release
--------------------
When publishing a final release there are extra steps that need to be taken:
* Run "make update-makeweb" to get a copy of the GNU Make web pages
* Run "make update-gnuweb" to get a copy of the GNU website boilerplate pages
* Update the web page boilerplate if necessary:
( cd ~/src/make/make-web \
&& ~/src/gnu-www/www/server/standards/patch-from-parent \
make.html \
~/src/gnu-www/www/server/standards/boilerplate.html )
* Run "make gendocs" (requires gnulib) to generate the manual files for
the GNU Make web pages.
* Follow the directions from gendocs for the web page repository
Manage the Savannah project for GNU Make:
* In Savannah edit the "Component Version" field and choose the "SCM" entry.
Modify the "Value", "Rank", and "Description" values for the to refer to
the new release. The "Rank" field should be 10 less than the previous
release so it orders properly.
* In Savannah edit the "Fixed Release" field and choose the "SCM" entry.
Modify the "Value", "Rank", and "Description" values for the to refer to
the new release. The "Rank" field should be 10 less than the previous
release so it orders properly.
* In Savannah create a new entry for the "Component Version" field:
- Value: SCM
- Rank: 20
- Descr: Issues found in code retrieved from Source Code Management (Git), rather than a distributed version. Please include the SHA you are working with.
* In Savannah create a new entry for the "Fix Release" field:
- Value: SCM
- Rank: 20
- Descr: Fixed in Source Code Management (Git). The fix will be included in the next release of GNU Make.
Upload a release using:
make upload-ftp
Announce a release to these mailing lists:
To: info-gnu@gnu.org, bug-make@gnu.org
BCC: help-make@gnu.org, make-w32@gnu.org, make-alpha@gnu.org
You will have to approve the BCC's on the mailing list admin sites. Send
separate copies to (don't use CC as replies will go to these lists):
* coordinator@translationproject.org
* platform-testers@gnu.org
Announce on Savannah:
* Add a news item to the Savannah project site.
Start the next release:
* Update configure.ac and add a ".90" to the release number.
* Update the NEWS file with a new section for the release / date.
* Update the Savannah URL for the bugs fixed in the NEWS section.
Appendix A - For The Brave
--------------------------
For those of you who trust me implicitly, or are just brave (or
foolhardy), here is a canned sequence of commands to build a GNU Make
distribution package from a virgin Git source checkout (assuming all the
prerequisites are available of course).
This list is eminently suitable for a quick swipe o' the mouse and a
swift click o' mouse-2 into an xterm. Go for it!
For a debugging version:
./bootstrap && ./configure CFLAGS=-g && make check
For an optimized version
./bootstrap && ./configure && make check

This directory contains the @PACKAGE_VERSION@ release of @PACKAGE_NAME@.
See the file NEWS for the user-visible changes from previous releases.
In addition, there have been bugs fixed.
>> If you are trying to build GNU Make from a Git clone rather than a

This README assumes you are building on a POSIX-based operating system.
For ports to other operating systems please see the system-specific README
files, as described in the "Ports" section below.
For source distribution building and installation instructions, see the file
INSTALL.
If you need to build GNU Make and have no other 'make' program to use, you can
use the shell script 'build.sh' instead. To do this, first run 'configure' as
described in INSTALL. Then, instead of typing 'make' to build the program,
type 'sh build.sh'. This will compile the program in the current directory.
Then you will have a 'make' program that you can use for './make install', or
whatever else.
Some systems' 'make' programs cannot process the Makefile for GNU Make.
If you get errors from your system's 'make' when building GNU Make, try using
'build.sh' instead.
GNU Make is free software. See the file COPYING for copying conditions.
GNU Make is copyright by the Free Software Foundation. Copyright notices
condense sequential years into a range; e.g. "1987-1994" means all years

Downloading
-----------
GNU Make can be obtained in many different ways. See a description here:
https://www.gnu.org/software/software.html
Documentation
-------------
GNU Make is fully documented in the GNU Make manual, which is contained in
this distribution as the file make.texi. You can also find on-line and
preformatted (PostScript and DVI) versions at the FSF's web site. There is
information there about ordering hardcopy documentation.

And the GNU Make development page is here:
https://savannah.gnu.org/projects/make/
You can find most information concerning the development of GNU Make at
this site.
Regression Tests
----------------
GNU Make contains a suite of regression tests. To run them use "make check"
after building GNU Make. If they fail a tar package will be created
containing useful information, which can be emailed (as an attachment) to
the <bug-make@gnu.org> mailing list.
Please note that since these tests rely on known-good-output comparisons,
they can show spurious failures on some systems (particularly non-POSIX systems
such as Windows).
Bug Reporting

Submitting Patches
------------------
If you'd like to propose a change to GNU Make, you can provide a patch with
your changes. If you are making your changes in a Git workspace you can run
"git format-patch" to create a patch file. If not, you can use the diff(1)
utility to create a patch file; please use "diff -u".
Once you have a patch you can submit it in any of these ways:
* Create a bug on Savannah and add the patch as an attachment:
https://savannah.gnu.org/bugs/?group=make&func=additem
* Send the patch via email to <bug-make@gnu.org>: be sure to add it as an
attachment to avoid interference by email processors.
All non-trivial changes require FSF copyright paperwork to be completed
before they can be accepted. Contact <bug-make@gnu.org> for help.
Git Access
----------
The GNU Make source repository is available via Git from the GNU Savannah Git
server; look here for details:
https://savannah.gnu.org/git/?group=make
Please note: you won't be able to build GNU Make from Git without installing
appropriate maintainer's tools, such as GNU m4, automake, autoconf, Perl, GNU
make, and GCC.
See the README.git file for instructions on how to build GNU Make once these
tools are available. We make no guarantees about the contents or quality of
the latest code in the Git repository: it is not unheard of for code that is
known to be broken to be checked in. Use at your own risk.
System-specific Notes
---------------------
One area that is often a problem in configuration and porting is the code
to check the system's current load average. To make it easier to test and
debug this code, you can do 'make check-loadavg' to see if it works
properly on your system. (You must run 'configure' beforehand, but you
need not build 'make' itself to run this test.)
Another potential source of porting problems is the support for large
files (LFS) in configure for those operating systems that provide it.
Please report any bugs that you find in this area. If you run into
difficulties, then as a workaround you should be able to disable LFS by
adding the '--disable-largefile' option to the 'configure' script.
On systems that support micro- and nano-second timestamp values and
where stat(2) provides this information, GNU Make will use it when
comparing timestamps to get the most accurate possible result. However,
note that many current implementations of tools that *set* timestamps do
not preserve micro- or nano-second granularity. This means that "cp -p"
and other similar tools (tar, etc.) may not exactly duplicate timestamps
with micro- and nano-second granularity on some systems. If your build
system contains rules that depend on proper behavior of tools like "cp
-p", you should consider using the .LOW_RESOLUTION_TIME pseudo-target to
force make to treat them properly. See the manual for details.
Ports
-----
- See README.customs for details on integrating GNU Make with the
Customs distributed build environment from the Pmake distribution.
- See README.VMS for details about GNU Make on OpenVMS.
- See README.zOS for details about GNU Make on z/OS.
- See README.W32 for details about GNU Make on Windows NT, 95, or 98.
- See README.DOS for compilation instructions on MS-DOS and MS-Windows
using DJGPP tools.
A precompiled binary of the MSDOS port of GNU Make is available as part
of DJGPP; see the WWW page https://www.delorie.com/djgpp/ for more
information.
The Cygwin project maintains its own port of GNU Make. That port may have
patches which are not present in this version. If you are using Cygwin
you should use their version of GNU Make, and if you have questions about
it you should start by asking on those mailing lists and forums.
Please note there are two _separate_ ports of GNU Make for Microsoft
systems: a native Windows port built with (for example) MSVC or MinGW,
and a DOS-based port built with DJGPP. Please be sure you are looking
at the right README!

This directory contains the VERSION test release of GNU Make.
All bugs reported for previous test releases have been fixed.
Some bugs surely remain.
For general building and installation instructions, see the file INSTALL.
If you need to build GNU Make and have no other `make' program to use,
you can use the shell script `build.sh' instead. To do this, first run
`configure' as described in INSTALL. Then, instead of typing `make' to
build the program, type `sh build.sh'. This should compile the program
in the current directory. Then you will have a Make program that you can
use for `make install', or whatever else.
It has been reported that the XLC 1.2 compiler on AIX 3.2 is buggy such
that if you compile make with `cc -O' on AIX 3.2, it will not work correctly.
It is said that using `cc' without `-O' does work.
One area that is often a problem in configuration and porting is the code
to check the system's current load average. To make it easier to test and
debug this code, you can do `make check-loadavg' to see if it works
properly on your system. (You must run `configure' beforehand, but you
need not build Make itself to run this test.)
See the file NEWS for what has changed since previous releases.
GNU Make is fully documented in make.texinfo. See the section entitled
`Problems and Bugs' for information on submitting bug reports.

GNU Make has been ported to z/OS, tested on z/OS V2R4.
PREREQUISITES
-------------
Building GNU Make requires certain tools be installed on your z/OS system.
These tools can be downloaded from: https://github.com/ZOSOpenTools
For detailed instructions on how to set up these tools, visit
https://zosopentools.github.io/meta/#/Guides/Pre-req
You will need curl, tar, and gzip to download and unpack the GNU Make release
package, but presumably you've already worked this out if you're reading this
document!
You will need the IBM C/C++ compiler. You can download a web deliverable
add-on feature to your XL C/C++ compiler here:
https://www-40.ibm.com/servers/resourcelink/svc00100.nsf/pages/xlCC++V241ForZOsV24
Alternatively, you can install and manage C/C++ for Open Enterprise Languages
on z/OS using RedHat OpenShift Container Platform and IBM Z and Cloud
Modernization Stack.
GNU Make has a dependency on the ZOSLIB library, which is documented here:
https://zosopentools.github.io/meta/#/Guides/Zoslib.
To obtain the latest release of zoslib, you can download it from here:
https://github.com/ZOSOpenTools/zoslibport/releases.
BUILDING
--------
If you are trying to build from a checked-out Git workspace, see README.git.
Before building GNU Make, you will need to ensure that the following
environment variables are set, to turn on z/OS enhanced ASCII support:
export _BPXK_AUTOCVT=ON
export _CEE_RUNOPTS="$_CEE_RUNOPTS FILETAG(AUTOCVT,AUTOTAG) POSIX(ON)"
export _TAG_REDIR_ERR=txt
export _TAG_REDIR_IN=txt
export _TAG_REDIR_OUT=txt
To ensure proper functioning of xlclang, set the following environment
variables before building:
export _CC_CCMODE=1
export _C89_CCMODE=1
export _CXX_CCMODE=1
Set PATH_TO_ZOSLIB to the location of your zoslib installation; e.g.:
PATH_TO_ZOSLIB=$HOME/zopen/prod/zoslib
Invoke ./configure as follows:
./configure \
CC=xlclang \
CPPFLAGS="-DNSIG=42 -D_XOPEN_SOURCE=600 -D_ALL_SOURCE -D_OPEN_SYS_FILE_EXT=1 -D_AE_BIMODAL=1 -D_ENHANCED_ASCII_EXT=0xFFFFFFF -DZOSLIB_OVERRIDE_CLIB=1" \
CFLAGS="-qascii -std=gnu11 -qnocsect -qenum=int -I$PATH_TO_ZOSLIB/include" \
LDFLAGS="-L$PATH_TO_ZOSLIB/lib" \
LIBS="-lzoslib $PATH_TO_ZOSLIB/lib/CXXRT64.x"
If you have an instance of make already available you can build with:
make
If not, you can build with:
./build.sh
TESTING
-------
To run the regression tests you'll need to install Perl and enable it.
Then you can run:
./make check
INSTALLING
----------
Copy the "make" program to wherever you want it to be installed, on your PATH.

GNU Make TODO List
------------------
This list comes both from the authors and from users of GNU make.
They are listed in no particular order!
Also, I don't guarantee that all of them will be ultimately deemed "good
ideas" and implemented. These are just the ones that, at first blush,
seem to have some merit (and that I can remember).
However, if you see something here you really, really want, speak up.
All other things being equal, I will tend to implement things that seem
to maximize user satisfaction.
If you want to implement some of them yourself, barring the ones I've
marked below, have at it! Please contact me first to let me know you're
working on it, and give me some info about the design--and, critically,
information about any user-visible syntax change, etc.
The Top Item
------------
If you know perl (or want to learn DejaGNU or similar), the number one
priority on my list of things I don't have time to do right now is
fixing up the GNU make test suite. Most importantly it needs to be made
"parallelizable", so more than one regression can run at the same time
(essentially, make the "work" directory local). Also, the CWD during
the test should be in the work directory or, better, a test-specific
temporary directory so each test gets a new directory; right now
sometimes tests leak files into the main directory which causes
subsequent tests to fail (some tests may need to be tweaked). Beyond
that, any cleanup done to make writing, reading, or handling tests
simpler would be great! Please feel free to make whatever changes you
like to the current tests, given some high-level goals, and that you'll
port the current tests to whatever you do :).
The Rest of the List
--------------------
1) Option to check more than timestamps to determine if targets have
changed. This is also a very big one. It's _close_ to my plate :),
and I have very definite ideas about how I would like it done.
Please pick something else unless you must have this feature. If
you try it, please work _extremely_ closely with me on it.
1a) Possibly a special case of this is the .KEEP_STATE feature of Sun's
make. Some great folks at W U. in Canada did an implementation of
this for a class project. Their approach is reasonable and
workable, but doesn't really fit into my ideas for #2. Maybe
that's OK. I have paperwork for their work so if you want to do
this one talk to me to get what they've already done.
[K R Praveen <praveen@cair.res.in>]
2) Currently you can use "%.foo %.bar : %.baz" to mean that one
invocation of the rule builds both targets. GNU make needs a way to
do that for explicit rules, too. I heard a rumor that some versions
of make all you to say "a.foo + a.bar : a.baz" to do this (i.e., a
"+" means one invocation builds both). Don't know if this is the
best syntax or not... what if you say "a.foo + a.bar a.bam : a.baz";
what does that mean?
3) Multi-token pattern rule matching (allow %1/%2.c : %1/obj/%2.o,
etc., or something like that). Maybe using regex?
4) Provide a .TARGETS variable, containing the names of the targets
defined in the makefile.
Actually, I now think a $(targets ...) function, at least, might be
better than a MAKETARGETS variable. The argument would be types of
targets to list: "phony" is the most useful one. I suppose
"default" might also be useful. Maybe some others; check the
bitfields to see what might be handy.
5) Some sort of operating-system independent way of handling paths
would be outstanding, so makefiles can be written for UNIX, VMS,
DOS, MS-Windows, Amiga, etc. with a minimum of specialization.
Or, perhaps related/instead of, some sort of meta-quoting syntax so
make can deal with filenames containing spaces, colons, etc. I
dunno, maybe something like $[...]? This may well not be worth
doing until #1 is done.
6) Right now the .PRECIOUS, .INTERMEDIATE, and .SECONDARY
pseudo-targets have different capabilities. For example, .PRECIOUS
can take a "%", the others can't. Etc. These should all work the
same, insofar as that makes sense.
7) Improved debugging/logging/etc. capabilities. Part of this is done:
I introduced a number of debugging enhancements. Tim Magill is (I
think) looking into options to control output more selectively.
One thing I want to do in debugging is add a flag to allow debugging
of variables as they're expanded (!). This would be incredibly
verbose, but could be invaluable when nothing else seems to work and
you just can't figure it out. The way variables are expanded now
means this isn't 100% trivial, but it probably won't be hard.

/* alloca.c -- allocate automatically reclaimed memory
(Mostly) portable public-domain implementation -- D A Gwyn
This implementation of the PWB library alloca function,
which is used to allocate space off the run-time stack so
that it is automatically reclaimed upon procedure exit,
was inspired by discussions with J. Q. Johnson of Cornell.
J.Otto Tennant <jot@cray.com> contributed the Cray support.
There are some preprocessor constants that can
be defined when compiling for your specific system, for
improved efficiency; however, the defaults should be okay.
The general concept of this implementation is to keep
track of all alloca-allocated blocks, and reclaim any
that are found to be deeper in the stack than the current
invocation. This heuristic does not reclaim storage as
soon as it becomes invalid, but it will do so eventually.
As a special case, alloca(0) reclaims storage without
allocating any. It is a good idea to use alloca(0) in
your main control loop, etc. to force garbage collection. */

Usage: $me [OPTION]...
Bootstrap this package from the checked-out sources.
Optional environment variables:
GNULIB_SRCDIR Specifies the local directory where gnulib
sources reside. Use this if you already
have gnulib sources on your machine, and
do not want to waste your bandwidth downloading
them again.
GNULIB_URL Cloneable URL of the gnulib repository.
Options:
--pull Do phase 1: pull files from network
--gen Do phase 2: generate from local files.
(The default is to do both phases.)
--gnulib-srcdir=DIRNAME specify the local directory where gnulib
sources reside. Use this if you already
have gnulib sources on your machine, and
you want to use these sources. Defaults
to \$GNULIB_SRCDIR
--gnulib-refdir=DIRNAME specify the local directory where a gnulib
repository (with a .git subdirectory) resides.
Use this if you already have gnulib sources
and history on your machine, and do not want
to waste your bandwidth downloading them again.
Defaults to \$GNULIB_REFDIR
--bootstrap-sync if this bootstrap script is not identical to
the version in the local gnulib sources,
update this script, and then restart it with
/bin/sh or the shell \$CONFIG_SHELL
--no-bootstrap-sync do not check whether bootstrap is out of sync
--copy copy files instead of creating symbolic links
--force attempt to bootstrap even if the sources seem
not to have been checked out
--no-git do not use git to update gnulib. Requires that
\$GNULIB_SRCDIR or the --gnulib-srcdir option
points to a gnulib repository with the correct
revision
--skip-po do not download po files
EOF
bootstrap_print_option_usage_hook
cat <<EOF
If the file bootstrap.conf exists in the same directory as this script, its
contents are read as shell variables to configure the bootstrap.
For build prerequisites, environment variables like \$AUTOCONF and \$AMTAR
are honored.
Gnulib sources can be fetched in various ways:
* If the environment variable GNULIB_SRCDIR is set (either as an
environment variable or via the --gnulib-srcdir option), then sources
are fetched from that local directory. If it is a git repository and
the configuration variable GNULIB_REVISION is set in bootstrap.conf,
then that revision is checked out.
* Otherwise, if this package is in a git repository with a 'gnulib'
submodule configured, then that submodule is initialized and updated
and sources are fetched from there. If GNULIB_REFDIR is set (either
as an environment variable or via the --gnulib-refdir option) and is
a git repository, then it is used as a reference.
* Otherwise, if the 'gnulib' directory does not exist, Gnulib sources
are cloned into that directory using git from \$GNULIB_URL, defaulting
to $default_gnulib_url.
If the configuration variable GNULIB_REVISION is set in bootstrap.conf,
then that revision is checked out.
* Otherwise, the existing Gnulib sources in the 'gnulib' directory are
used. If it is a git repository and the configuration variable
GNULIB_REVISION is set in bootstrap.conf, then that revision is
checked out.
If you maintain a package and want to pin a particular revision of the
Gnulib sources that has been tested with your package, then there are
two possible approaches: either configure a 'gnulib' submodule with the
appropriate revision, or set GNULIB_REVISION (and if necessary
GNULIB_URL) in bootstrap.conf.
Running without arguments will suffice in most cases.

.TH MAKE 1 "26 May 2023" "GNU" "User Commands"
.SH NAME
make \- GNU Make utility to maintain groups of programs
.SH SYNOPSIS
.B make
[\fIOPTION\fR]... [\fITARGET\fR]...
.SH DESCRIPTION
.LP
The
.I make
utility will determine automatically which pieces of a large program need to
be recompiled, and issue the commands to recompile them. The manual describes
the GNU implementation of
.BR make ,
which was written by Richard Stallman and Roland McGrath, and is currently
maintained by Paul Smith. Our examples show C programs, since they are very
common, but you can use
.B make
with any programming language whose compiler can be run with a shell command.
In fact,
.B make
is not limited to programs. You can use it to describe any task where some
files must be updated automatically from others whenever the others change.
.LP
To prepare to use
.BR make ,
you must write a file called the
.I makefile
that describes the relationships among files in your program, and provides
commands for updating each file. In a program, typically the executable file
is updated from object files, which are in turn made by compiling source
files.
.LP
Once a suitable makefile exists, each time you change some source files,
this simple shell command:
.sp 1
.RS
.B make
.RE
.sp 1
suffices to perform all necessary recompilations.
The
.B make
program uses the makefile description and the last-modification times of the
files to decide which of the files need to be updated. For each of those
files, it issues the commands recorded in the makefile.
.LP
.B make
executes commands in the
.I makefile
to update one or more
.IR targets ,
where
.I target
is typically a program.
If no
.B \-f
option is present,
.B make
will look for the makefiles
.IR GNUmakefile ,
.IR makefile ,
and
.IR Makefile ,
in that order.
.LP
Normally you should call your makefile either
.I makefile
or
.IR Makefile .
(We recommend
.I Makefile
because it appears prominently near the beginning of a directory
listing, right near other important files such as
.IR README .)
The first name checked,
.IR GNUmakefile ,
is not recommended for most makefiles. You should use this name if you have a
makefile that is specific to GNU Make, and will not be understood by other
versions of
.BR make .
If
.I makefile
is '\-', the standard input is read.
.LP
.B make
updates a target if it depends on prerequisite files
that have been modified since the target was last modified,
or if the target does not exist.
.SH OPTIONS
.sp 1
.TP 0.5i
\fB\-b\fR, \fB\-m\fR
These options are ignored for compatibility with other versions of
.BR make .
.TP 0.5i
\fB\-B\fR, \fB\-\-always\-make\fR
Unconditionally make all targets.
.TP 0.5i
\fB\-C\fR \fIdir\fR, \fB\-\-directory\fR=\fIdir\fR
Change to directory
.I dir
before reading the makefiles or doing anything else.
If multiple
.B \-C
options are specified, each is interpreted relative to the
previous one:
.BR "\-C " /
.BR "\-C " etc
is equivalent to
.BR "\-C " /etc.
This is typically used with recursive invocations of
.BR make .
.TP 0.5i
.B \-d
Print debugging information in addition to normal processing.
The debugging information says which files are being considered for
remaking, which file-times are being compared and with what results,
which files actually need to be remade, which implicit rules are
considered and which are applied---everything interesting about how
.B make
decides what to do.
.TP 0.5i
.BI \-\-debug "[=FLAGS]"
Print debugging information in addition to normal processing.
If the
.I FLAGS
are omitted, then the behavior is the same as if
.B \-d
was specified.
.I FLAGS
may be any or all of the following names, comma- or space-separated. Only the
first character is significant: the rest may be omitted:
.I all
for all debugging output (same as using
.BR \-d ),
.I basic
for basic debugging,
.I verbose
for more verbose basic debugging,
.I implicit
for showing implicit rule search operations,
.I jobs
for details on invocation of commands,
.I makefile
for debugging while remaking makefiles,
.I print
shows all recipes that are run even if they are silent, and
.I why
shows the reason
.BR make
decided to rebuild each target. Use
.I none
to disable all previous debugging flags.
.TP 0.5i
\fB\-e\fR, \fB\-\-environment\-overrides\fR
Give variables taken from the environment precedence over variables
from makefiles.
.TP 0.5i
\fB\-E\fR \fIstring\fR, \fB\-\-eval\fR \fIstring\fR
Interpret \fIstring\fR using the \fBeval\fR function, before parsing any
makefiles.
.TP 0.5i
\fB\-f\fR \fIfile\fR, \fB\-\-file\fR=\fIfile\fR, \fB\-\-makefile\fR=\fIFILE\fR
Use
.I file
as a makefile.
.TP 0.5i
\fB\-i\fR, \fB\-\-ignore\-errors\fR
Ignore all errors in commands executed to remake files.
.TP 0.5i
\fB\-I\fR \fIdir\fR, \fB\-\-include\-dir\fR=\fIdir\fR
Specifies a directory
.I dir
to search for included makefiles.
If several
.B \-I
options are used to specify several directories, the directories are
searched in the order specified.
Unlike the arguments to other flags of
.BR make ,
directories given with
.B \-I
flags may come directly after the flag:
.BI \-I dir
is allowed, as well as
.B \-I
.IR dir .
This syntax is allowed for compatibility with the C
preprocessor's
.B \-I
flag.
.TP 0.5i
\fB\-j\fR [\fIjobs\fR], \fB\-\-jobs\fR[=\fIjobs\fR]
Specifies the number of
.I jobs
(commands) to run simultaneously.
If there is more than one
.B \-j
option, the last one is effective.
If the
.B \-j
option is given without an argument,
.BR make
will not limit the number of jobs that can run simultaneously.
.TP 0.5i
\fB\--jobserver-style=\fR\fIstyle\fR
The style of jobserver to use. The
.I style
may be one of
.BR fifo ,
.BR pipe ,
or
.B sem
(Windows only).
.TP 0.5i
\fB\-k\fR, \fB\-\-keep\-going\fR
Continue as much as possible after an error.
While the target that failed, and those that depend on it, cannot
be remade, the other dependencies of these targets can be processed
all the same.
.TP 0.5i
\fB\-l\fR [\fIload\fR], \fB\-\-load\-average\fR[=\fIload\fR]
Specifies that no new jobs (commands) should be started if there are
others jobs running and the load average is at least
.I load
(a floating-point number).
With no argument, removes a previous load limit.
.TP 0.5i
\fB\-L\fR, \fB\-\-check\-symlink\-times\fR
Use the latest mtime between symlinks and target.
.TP 0.5i
\fB\-n\fR, \fB\-\-just\-print\fR, \fB\-\-dry\-run\fR, \fB\-\-recon\fR
Print the commands that would be executed, but do not execute them (except in
certain circumstances).
.TP 0.5i
\fB\-o\fR \fIfile\fR, \fB\-\-old\-file\fR=\fIfile\fR, \fB\-\-assume\-old\fR=\fIfile\fR
Do not remake the file
.I file
even if it is older than its dependencies, and do not remake anything
on account of changes in
.IR file .
Essentially the file is treated as very old and its rules are ignored.
.TP 0.5i
\fB\-O\fR[\fItype\fR], \fB\-\-output\-sync\fR[=\fItype\fR]
When running multiple jobs in parallel with \fB-j\fR, ensure the output of
each job is collected together rather than interspersed with output from
other jobs. If
.I type
is not specified or is
.B target
the output from the entire recipe for each target is grouped together. If
.I type
is
.B line
the output from each command line within a recipe is grouped together.
If
.I type
is
.B recurse
output from an entire recursive make is grouped together. If
.I type
is
.B none
output synchronization is disabled.
.TP 0.5i
\fB\-p\fR, \fB\-\-print\-data\-base\fR
Print the data base (rules and variable values) that results from
reading the makefiles; then execute as usual or as otherwise
specified.
This also prints the version information given by the
.B \-v
switch (see below). To print the built-in data base only, use
.IR "make \-p \-f/dev/null" .
.TP 0.5i
\fB\-\-print\-targets\fR
Print each target defined as a result of reading the makefiles, one target per
line, then exit with success. Implicit rule targets are not printed, nor are
special targets (target names that consist of "." followed by all upper-case
letters). No recipe commands are invoked and no makefiles are rebuilt.
.TP 0.5i
\fB\-q\fR, \fB\-\-question\fR
``Question mode''.
Do not run any commands, or print anything; just return an exit status
that is zero if the specified targets are already up to date, nonzero
otherwise.
.TP 0.5i
\fB\-r\fR, \fB\-\-no\-builtin\-rules\fR
Eliminate use of the built\-in implicit rules.
Also clear out the default list of suffixes for suffix rules.
.TP 0.5i
\fB\-R\fR, \fB\-\-no\-builtin\-variables\fR
Don't define any built\-in variables.
.TP 0.5i
\fB\-s\fR, \fB\-\-silent\fR, \fB\-\-quiet\fR
Silent operation; do not print the commands as they are executed.
.TP 0.5i
.B \-\-no\-silent
Cancel the effect of the \fB\-s\fR option.
.TP 0.5i
\fB\-S\fR, \fB\-\-no\-keep\-going\fR, \fB\-\-stop\fR
Cancel the effect of the
.B \-k
option.
.TP 0.5i
\fB\-t\fR, \fB\-\-touch\fR
Touch files (mark them up to date without really changing them)
instead of running their commands.
This is used to pretend that the commands were done, in order to fool
future invocations of
.BR make .
.TP 0.5i
.B \-\-trace
Information about the disposition of each target is printed (why the target is
being rebuilt and what commands are run to rebuild it).
.TP 0.5i
\fB\-v\fR, \fB\-\-version\fR
Print the version of the
.B make
program plus a copyright, a list of authors and a notice that there
is no warranty.
.TP 0.5i
\fB\-w\fR, \fB\-\-print\-directory\fR
Print a message containing the working directory
before and after other processing.
This may be useful for tracking down errors from complicated nests of
recursive
.B make
commands.
.TP 0.5i
.B \-\-no\-print\-directory
Turn off
.BR \-w ,
even if it was turned on implicitly.
.TP 0.5i
.BI \-\-shuffle "[=MODE]"
Enable shuffling of goal and prerequisite ordering.
.I MODE
is one of
.I none
to disable shuffle mode,
.I random
to shuffle prerequisites in random order,
.I reverse
to consider prerequisites in reverse order, or an integer
.I <seed>
which enables
.I random
mode with a specific
.I seed
value. If
.I MODE
is omitted the default is
.IR random .
.TP 0.5i
\fB\-W\fR \fIfile\fR, \fB\-\-what\-if\fR=\fIfile\fR, \fB\-\-new\-file\fR=\fIfile\fR, \fB\-\-assume\-new\fR=\fIfile\fR
Pretend that the target
.I file
has just been modified.
When used with the
.B \-n
flag, this shows you what would happen if you were to modify that file.
Without
.BR \-n ,
it is almost the same as running a
.I touch
command on the given file before running
.BR make ,
except that the modification time is changed only in the imagination of
.BR make .
.TP 0.5i
\fB\-\-warn\fR[=\fIARG[\fR,\fIARG\fR]]
Control warning reporting for makefiles. This option can appear multiple times.
In case of conflicts, later settings override earlier settings.
.I ARG
can be an action; one of
.IR ignore ,
.IR warn ,
or
.I error
to set the default action for all warnings, or it can be a specific warning:
.I circular-dep
(finding a circular dependency),
.I invalid-ref
(referencing an invalid variable name),
.I invalid-var
(assigning to an invalid variable name),
or
.I undefined-var
(referencing an undefined variable). The behavior of each warning can be set
by adding
.BI : action
after the warning name. If an action is not specified the default is
.IR warn .
If no
.I ARG
is provided the action for all warnings is
.IR warn .
If no
.B \-\-warn
option is provided the default action for
.I invalid-var
and
.I invalid-ref
is
.I warn
and the default action for
.I undefined-var
is
.IR ignore .
.TP 0.5i
.B \-\-warn\-undefined\-variables
A deprecated alternative for
.BR \-\-warn=undefined-var .
.TP 0.5i
.B \-
This option alone (not as an argument to the
.B \-f
option) is ignored, unless a target named
.B \-
is defined in the makefile, in which case that target is added to the makefile
goals.
.SH "EXIT STATUS"
GNU Make exits with a status of zero if all makefiles were successfully parsed
and no targets that were built failed. A status of one will be returned
if the
.B \-q
flag was used and
.B make
determines that a target needs to be rebuilt. A status of two will be
returned if any errors were encountered.
.SH "SEE ALSO"
The full documentation for
.B make
is maintained as a Texinfo manual. If the
.B info
and
.B make
programs are properly installed at your site, the command
.IP
.B info make
.PP
should give you access to the complete manual.

04 July 2022 -*-text-*-
The gnulib project provides a fantastic array of modules that can support both
POSIX and also extended features for GNU software.
Unfortunately using it in GNU make is problematic: GNU make is a foundational
utility (if you don't have a "make" program you pretty much can't build any
software), one of our goals in GNU make is to provide scripts (e.g.,
"build.sh") that will build GNU make without needing an instance of make.
Instead of running "./configure && make", you should be able to run
"./configure && ./build.sh" and get a build of GNU make as a result.
However, more and more gnulib modules are relying not on M4 macros and
the configure script to manage their configuration, but in addition special
makefile recipes that perform various post-configure operations. Since we
don't have an instance of "make", we cannot use these modules as-is.
There are various options we could choose for solving this:
- Avoid gnulib modules and write our own portability interfaces.
I really am not too excited about this.
- Give up on "build.sh" and require users to already have "make".
The argument here is that you must already have a compiler, and it couldn't
have been built without "make", and/or if you build it with a cross-compiler
then you should be able to use that cross-development environment to build
GNU make as well.
- Provide a "mini-make" with just enough functionality to support the gnulib
makefiles but no extra features, that didn't need any complex gnulib
modules. As with the first option, I'm not too excited about this.
Although arguably the second option is the sane one, I'm not really excited
about any of them for the time being. So I elected to try something between
the first and second options:
The gnulib-port Git branch will contain unmodified copies of gnulib modules
that we want to use with GNU make. From there, we merge them into the main
Git branch then modify / simplify them to avoid unnecessary extra modules and
allow "build.sh" to be used.
By keeping the unmodified versions on the gnulib-port branch, we enable Git
merge facilities to merge in new versions as follows:
* Check out the gnulib-port branch
* Update its content with any updates to gnulib modules. Something like:
(
cd gl \
&& find */. -type f \
| while read fn; do
test -f "$GNULIB_SRCDIR/$fn" && cp "$GNULIB_SRCDIR/$fn" "$fn"
done
)
* Commit the changes _without modification_
* Check out the main branch
* Run "git merge --no-ff gnulib-port" to merge in the changes
* Resolve any conflicts and commit the merge.

GNU LIBRARY GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1991 Free Software Foundation, Inc.
675 Mass Ave, Cambridge, MA 02139, USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
[This is the first released version of the library GPL. It is
numbered 2 because it goes with version 2 of the ordinary GPL.]
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
Licenses are intended to guarantee your freedom to share and change
free software--to make sure the software is free for all its users.
This license, the Library General Public License, applies to some
specially designated Free Software Foundation software, and to any
other libraries whose authors decide to use it. You can use it for
your libraries, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if
you distribute copies of the library, or if you modify it.
For example, if you distribute copies of the library, whether gratis
or for a fee, you must give the recipients all the rights that we gave
you. You must make sure that they, too, receive or can get the source
code. If you link a program with the library, you must provide
complete object files to the recipients so that they can relink them
with the library, after making changes to the library and recompiling
it. And you must show them these terms so they know their rights.
Our method of protecting your rights has two steps: (1) copyright
the library, and (2) offer you this license which gives you legal
permission to copy, distribute and/or modify the library.
Also, for each distributor's protection, we want to make certain
that everyone understands that there is no warranty for this free
library. If the library is modified by someone else and passed on, we
want its recipients to know that what they have is not the original
version, so that any problems introduced by others will not reflect on
the original authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that companies distributing free
software will individually obtain patent licenses, thus in effect
transforming the program into proprietary software. To prevent this,
we have made it clear that any patent must be licensed for everyone's
free use or not licensed at all.
Most GNU software, including some libraries, is covered by the ordinary
GNU General Public License, which was designed for utility programs. This
license, the GNU Library General Public License, applies to certain
designated libraries. This license is quite different from the ordinary
one; be sure to read it in full, and don't assume that anything in it is
the same as in the ordinary license.
The reason we have a separate public license for some libraries is that
they blur the distinction we usually make between modifying or adding to a
program and simply using it. Linking a program with a library, without
changing the library, is in some sense simply using the library, and is
analogous to running a utility program or application program. However, in
a textual and legal sense, the linked executable is a combined work, a
derivative of the original library, and the ordinary General Public License
treats it as such.
Because of this blurred distinction, using the ordinary General
Public License for libraries did not effectively promote software
sharing, because most developers did not use the libraries. We
concluded that weaker conditions might promote sharing better.
However, unrestricted linking of non-free programs would deprive the
users of those programs of all benefit from the free status of the
libraries themselves. This Library General Public License is intended to
permit developers of non-free programs to use free libraries, while
preserving your freedom as a user of such programs to change the free
libraries that are incorporated in them. (We have not seen how to achieve
this as regards changes in header files, but we have achieved it as regards
changes in the actual functions of the Library.) The hope is that this
will lead to faster development of free libraries.
The precise terms and conditions for copying, distribution and
modification follow. Pay close attention to the difference between a
"work based on the library" and a "work that uses the library". The
former contains code derived from the library, while the latter only
works together with the library.
Note that it is possible for a library to be covered by the ordinary
General Public License rather than by this special one.
GNU LIBRARY GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library which
contains a notice placed by the copyright holder or other authorized
party saying it may be distributed under the terms of this Library
General Public License (also called "this License"). Each licensee is
addressed as "you".
A "library" means a collection of software functions and/or data
prepared so as to be conveniently linked with application programs
(which use some of those functions and data) to form executables.
The "Library", below, refers to any such software library or work
which has been distributed under these terms. A "work based on the
Library" means either the Library or any derivative work under
copyright law: that is to say, a work containing the Library or a
portion of it, either verbatim or with modifications and/or translated
straightforwardly into another language. (Hereinafter, translation is
included without limitation in the term "modification".)
"Source code" for a work means the preferred form of the work for
making modifications to it. For a library, complete source code means
all the source code for all modules it contains, plus any associated
interface definition files, plus the scripts used to control compilation
and installation of the library.
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running a program using the Library is not restricted, and output from
such a program is covered only if its contents constitute a work based
on the Library (independent of the use of the Library in a tool for
writing it). Whether that is true depends on what the Library does
and what the program that uses the Library does.
1. You may copy and distribute verbatim copies of the Library's
complete source code as you receive it, in any medium, provided that
you conspicuously and appropriately publish on each copy an
appropriate copyright notice and disclaimer of warranty; keep intact
all the notices that refer to this License and to the absence of any
warranty; and distribute a copy of this License along with the
Library.
You may charge a fee for the physical act of transferring a copy,
and you may at your option offer warranty protection in exchange for a
fee.
2. You may modify your copy or copies of the Library or any portion
of it, thus forming a work based on the Library, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) The modified work must itself be a software library.
b) You must cause the files modified to carry prominent notices
stating that you changed the files and the date of any change.
c) You must cause the whole of the work to be licensed at no
charge to all third parties under the terms of this License.
d) If a facility in the modified Library refers to a function or a
table of data to be supplied by an application program that uses
the facility, other than as an argument passed when the facility
is invoked, then you must make a good faith effort to ensure that,
in the event an application does not supply such function or
table, the facility still operates, and performs whatever part of
its purpose remains meaningful.
(For example, a function in a library to compute square roots has
a purpose that is entirely well-defined independent of the
application. Therefore, Subsection 2d requires that any
application-supplied function or table used by this function must
be optional: if the application does not supply it, the square
root function must still compute square roots.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Library,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Library, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote
it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Library.
In addition, mere aggregation of another work not based on the Library
with the Library (or with a work based on the Library) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may opt to apply the terms of the ordinary GNU General Public
License instead of this License to a given copy of the Library. To do
this, you must alter all the notices that refer to this License, so
that they refer to the ordinary GNU General Public License, version 2,
instead of to this License. (If a newer version than version 2 of the
ordinary GNU General Public License has appeared, then you can specify
that version instead if you wish.) Do not make any other change in
these notices.
Once this change is made in a given copy, it is irreversible for
that copy, so the ordinary GNU General Public License applies to all
subsequent copies and derivative works made from that copy.
This option is useful when you wish to copy part of the code of
the Library into a program that is not a library.
4. You may copy and distribute the Library (or a portion or
derivative of it, under Section 2) in object code or executable form
under the terms of Sections 1 and 2 above provided that you accompany
it with the complete corresponding machine-readable source code, which
must be distributed under the terms of Sections 1 and 2 above on a
medium customarily used for software interchange.
If distribution of object code is made by offering access to copy
from a designated place, then offering equivalent access to copy the
source code from the same place satisfies the requirement to
distribute the source code, even though third parties are not
compelled to copy the source along with the object code.
5. A program that contains no derivative of any portion of the
Library, but is designed to work with the Library by being compiled or
linked with it, is called a "work that uses the Library". Such a
work, in isolation, is not a derivative work of the Library, and
therefore falls outside the scope of this License.
However, linking a "work that uses the Library" with the Library
creates an executable that is a derivative of the Library (because it
contains portions of the Library), rather than a "work that uses the
library". The executable is therefore covered by this License.
Section 6 states terms for distribution of such executables.
When a "work that uses the Library" uses material from a header file
that is part of the Library, the object code for the work may be a
derivative work of the Library even though the source code is not.
Whether this is true is especially significant if the work can be
linked without the Library, or if the work is itself a library. The
threshold for this to be true is not precisely defined by law.
If such an object file uses only numerical parameters, data
structure layouts and accessors, and small macros and small inline
functions (ten lines or less in length), then the use of the object
file is unrestricted, regardless of whether it is legally a derivative
work. (Executables containing this object code plus portions of the
Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may
distribute the object code for the work under the terms of Section 6.
Any executables containing that work also fall under Section 6,
whether or not they are linked directly with the Library itself.
6. As an exception to the Sections above, you may also compile or
link a "work that uses the Library" with the Library to produce a
work containing portions of the Library, and distribute that work
under terms of your choice, provided that the terms permit
modification of the work for the customer's own use and reverse
engineering for debugging such modifications.
You must give prominent notice with each copy of the work that the
Library is used in it and that the Library and its use are covered by
this License. You must supply a copy of this License. If the work
during execution displays copyright notices, you must include the
copyright notice for the Library among them, as well as a reference
directing the user to the copy of this License. Also, you must do one
of these things:
a) Accompany the work with the complete corresponding
machine-readable source code for the Library including whatever
changes were used in the work (which must be distributed under
Sections 1 and 2 above); and, if the work is an executable linked
with the Library, with the complete machine-readable "work that
uses the Library", as object code and/or source code, so that the
user can modify the Library and then relink to produce a modified
executable containing the modified Library. (It is understood
that the user who changes the contents of definitions files in the
Library will not necessarily be able to recompile the application
to use the modified definitions.)
b) Accompany the work with a written offer, valid for at
least three years, to give the same user the materials
specified in Subsection 6a, above, for a charge no more
than the cost of performing this distribution.
c) If distribution of the work is made by offering access to copy
from a designated place, offer equivalent access to copy the above
specified materials from the same place.
d) Verify that the user has already received a copy of these
materials or that you have already sent this user a copy.
For an executable, the required form of the "work that uses the
Library" must include any data and utility programs needed for
reproducing the executable from it. However, as a special exception,
the source code distributed need not include anything that is normally
distributed (in either source or binary form) with the major
components (compiler, kernel, and so on) of the operating system on
which the executable runs, unless that component itself accompanies
the executable.
It may happen that this requirement contradicts the license
restrictions of other proprietary libraries that do not normally
accompany the operating system. Such a contradiction means you cannot
use both them and the Library together in an executable that you
distribute.
7. You may place library facilities that are a work based on the
Library side-by-side in a single library together with other library
facilities not covered by this License, and distribute such a combined
library, provided that the separate distribution of the work based on
the Library and of the other library facilities is otherwise
permitted, and provided that you do these two things:
a) Accompany the combined library with a copy of the same work
based on the Library, uncombined with any other library
facilities. This must be distributed under the terms of the
Sections above.
b) Give prominent notice with the combined library of the fact
that part of it is a work based on the Library, and explaining
where to find the accompanying uncombined form of the same work.
8. You may not copy, modify, sublicense, link with, or distribute
the Library except as expressly provided under this License. Any
attempt otherwise to copy, modify, sublicense, link with, or
distribute the Library is void, and will automatically terminate your
rights under this License. However, parties who have received copies,
or rights, from you under this License will not have their licenses
terminated so long as such parties remain in full compliance.
9. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Library or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Library (or any work based on the
Library), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Library or works based on it.
10. Each time you redistribute the Library (or any work based on the
Library), the recipient automatically receives a license from the
original licensor to copy, distribute, link with or modify the Library
subject to these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
11. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Library at all. For example, if a patent
license would not permit royalty-free redistribution of the Library by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Library.
If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply,
and the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
12. If the distribution and/or use of the Library is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Library under this License may add
an explicit geographical distribution limitation excluding those countries,
so that distribution is permitted only in or among countries not thus
excluded. In such case, this License incorporates the limitation as if
written in the body of this License.
13. The Free Software Foundation may publish revised and/or new
versions of the Library General Public License from time to time.
Such new versions will be similar in spirit to the present version,
but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Library
specifies a version number of this License which applies to it and
"any later version", you have the option of following the terms and
conditions either of that version or of any later version published by
the Free Software Foundation. If the Library does not specify a
license version number, you may choose any version ever published by
the Free Software Foundation.
14. If you wish to incorporate parts of the Library into other free
programs whose distribution conditions are incompatible with these,
write to the author to ask for permission. For software which is
copyrighted by the Free Software Foundation, write to the Free
Software Foundation; we sometimes make exceptions for this. Our
decision will be guided by the two goals of preserving the free status
of all derivatives of our free software and of promoting the sharing
and reuse of software generally.
NO WARRANTY
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES.
END OF TERMS AND CONDITIONS
Appendix: How to Apply These Terms to Your New Libraries
If you develop a new library, and you want it to be of the greatest
possible use to the public, we recommend making it free software that
everyone can redistribute and change. You can do so by permitting
redistribution under these terms (or, alternatively, under the terms of the
ordinary General Public License).
To apply these terms, attach the following notices to the library. It is
safest to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least the
"copyright" line and a pointer to where the full notice is found.
<one line to give the library's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This library is free software; you can redistribute it and/or
modify it under the terms of the GNU Library General Public
License as published by the Free Software Foundation; either
version 2 of the License, or (at your option) any later version.
This library is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
Library General Public License for more details.
You should have received a copy of the GNU Library General Public
License along with this library; if not, write to the Free
Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
Also add information on how to contact you by electronic and paper mail.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the library, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the
library `Frob' (a library for tweaking knobs) written by James Random Hacker.

@unnumberedsec Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software---to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.

interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
@end enumerate
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
@item
You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
@enumerate a
@item
Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
@item
Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
@item
Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
@end enumerate
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
@item
You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
@item
You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
@item
Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
@item
If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
@item
If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
@item
The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and ``any
later version'', you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
@item
If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.

@unnumberedsec How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the ``copyright'' line and a pointer to where the full notice is found.
@smallexample
@var{one line to give the program's name and an idea of what it does.}

but WITHOUT ANY WARRANTY; without even the implied warranty of

You should have received a copy of the GNU General Public License

Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
@end smallexample
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
@smallexample
Gnomovision version 69, Copyright (C) 19@var{yy} @var{name of author}
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details
type `show w'. This is free software, and you are welcome
to redistribute it under certain conditions; type `show c'
for details.
@end smallexample
The hypothetical commands @samp{show w} and @samp{show c} should show
the appropriate parts of the General Public License. Of course, the
commands you use may be called something other than @samp{show w} and
@samp{show c}; they could even be mouse-clicks or menu items---whatever
suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a ``copyright disclaimer'' for the program, if
necessary. Here is a sample; alter the names:
@smallexample
@group
Yoyodyne, Inc., hereby disclaims all copyright

This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General
Public License instead of this License.

@node Makefile Basics
@section General Conventions for Makefiles
Every Makefile should contain this line:
@example
SHELL = /bin/sh
@end example
@noindent
to avoid trouble on systems where the @code{SHELL} variable might be
inherited from the environment. (This is never a problem with GNU
@code{make}.)
Different @code{make} programs have incompatible suffix lists and
implicit rules, and this sometimes creates confusion or misbehavior. So
it is a good idea to set the suffix list explicitly using only the
suffixes you need in the particular Makefile, like this:
@example
.SUFFIXES:
.SUFFIXES: .c .o
@end example
@noindent
The first line clears out the suffix list, the second introduces all
suffixes which may be subject to implicit rules in this Makefile.
Don't assume that @file{.} is in the path for command execution. When
you need to run programs that are a part of your package during the
make, please make sure that it uses @file{./} if the program is built as
part of the make or @file{$(srcdir)/} if the file is an unchanging part
of the source code. Without one of these prefixes, the current search
path is used.
The distinction between @file{./} and @file{$(srcdir)/} is important
when using the @samp{--srcdir} option to @file{configure}. A rule of
the form:
@smallexample
foo.1 : foo.man sedscript
sed -e sedscript foo.man > foo.1
@end smallexample
@noindent
will fail when the current directory is not the source directory,
because @file{foo.man} and @file{sedscript} are not in the current
directory.
When using GNU @code{make}, relying on @samp{VPATH} to find the source
file will work in the case where there is a single dependency file,
since the @file{make} automatic variable @samp{$<} will represent the
source file wherever it is. (Many versions of @code{make} set @samp{$<}
only in implicit rules.) A makefile target like
@smallexample
foo.o : bar.c
$(CC) -I. -I$(srcdir) $(CFLAGS) -c bar.c -o foo.o
@end smallexample
@noindent
should instead be written as
@smallexample
foo.o : bar.c
$(CC) -I. -I$(srcdir) $(CFLAGS) -c $< -o $@@
@end smallexample
@noindent
in order to allow @samp{VPATH} to work correctly. When the target has
multiple dependencies, using an explicit @samp{$(srcdir)} is the easiest
way to make the rule work well. For example, the target above for
@file{foo.1} is best written as:
@smallexample
foo.1 : foo.man sedscript
sed -e $(srcdir)/sedscript $(srcdir)/foo.man > $@@
@end smallexample
@node Utilities in Makefiles
@section Utilities in Makefiles
Write the Makefile commands (and any shell scripts, such as
@code{configure}) to run in @code{sh}, not in @code{csh}. Don't use any
special features of @code{ksh} or @code{bash}.
The @code{configure} script and the Makefile rules for building and
installation should not use any utilities directly except these:
@example
cat cmp cp echo egrep expr grep
ln mkdir mv pwd rm rmdir sed test touch
@end example
Stick to the generally supported options for these programs. For
example, don't use @samp{mkdir -p}, convenient as it may be, because
most systems don't support it.
The Makefile rules for building and installation can also use compilers
and related programs, but should do so via @code{make} variables so that the
user can substitute alternatives. Here are some of the programs we
mean:
@example
ar bison cc flex install ld lex
make makeinfo ranlib texi2dvi yacc
@end example
Use the following @code{make} variables:
@example
$(AR) $(BISON) $(CC) $(FLEX) $(INSTALL) $(LD) $(LEX)
$(MAKE) $(MAKEINFO) $(RANLIB) $(TEXI2DVI) $(YACC)
@end example
When you use @code{ranlib}, you should make sure nothing bad happens if
the system does not have @code{ranlib}. Arrange to ignore an error
from that command, and print a message before the command to tell the
user that failure of the @code{ranlib} command does not mean a problem.
If you use symbolic links, you should implement a fallback for systems
that don't have symbolic links.
It is ok to use other utilities in Makefile portions (or scripts)
intended only for particular systems where you know those utilities to
exist.
@node Standard Targets
@section Standard Targets for Users
All GNU programs should have the following targets in their Makefiles:
@table @samp
@item all
Compile the entire program. This should be the default target. This
target need not rebuild any documentation files; Info files should
normally be included in the distribution, and DVI files should be made
only when explicitly asked for.
@item install
Compile the program and copy the executables, libraries, and so on to
the file names where they should reside for actual use. If there is a
simple test to verify that a program is properly installed, this target
should run that test.
If possible, write the @code{install} target rule so that it does not
modify anything in the directory where the program was built, provided
@samp{make all} has just been done. This is convenient for building the
program under one user name and installing it under another.
The commands should create all the directories in which files are to be
installed, if they don't already exist. This includes the directories
specified as the values of the variables @code{prefix} and
@code{exec_prefix}, as well as all subdirectories that are needed.
One way to do this is by means of an @code{installdirs} target
as described below.
Use @samp{-} before any command for installing a man page, so that
@code{make} will ignore any errors. This is in case there are systems
that don't have the Unix man page documentation system installed.
The way to install Info files is to copy them into @file{$(infodir)}
with @code{$(INSTALL_DATA)} (@pxref{Command Variables}), and then run
the @code{install-info} program if it is present. @code{install-info}
is a script that edits the Info @file{dir} file to add or update the
menu entry for the given Info file; it will be part of the Texinfo package.
Here is a sample rule to install an Info file:
@comment This example has been carefully formatted for the Make manual.
@comment Please do not reformat it without talking to roland@gnu.ai.mit.edu.
@smallexample
$(infodir)/foo.info: foo.info
# There may be a newer info file in . than in srcdir.
-if test -f foo.info; then d=.; \
else d=$(srcdir); fi; \
$(INSTALL_DATA) $$d/foo.info $@@; \
# Run install-info only if it exists.
# Use `if' instead of just prepending `-' to the
# line so we notice real errors from install-info.
# We use `$(SHELL) -c' because some shells do not
# fail gracefully when there is an unknown command.
if $(SHELL) -c 'install-info --version' \
>/dev/null 2>&1; then \
install-info --infodir=$(infodir) $$d/foo.info; \
else true; fi
@end smallexample
@item uninstall
Delete all the installed files that the @samp{install} target would
create (but not the noninstalled files such as @samp{make all} would
create).
This rule should not modify the directories where compilation is done,
only the directories where files are installed.
@comment The gratuitous blank line here is to make the table look better
@comment in the printed Make manual. Please leave it in.
@item clean
Delete all files from the current directory that are normally created by
building the program. Don't delete the files that record the
configuration. Also preserve files that could be made by building, but
normally aren't because the distribution comes with them.
Delete @file{.dvi} files here if they are not part of the distribution.
@item distclean
Delete all files from the current directory that are created by
configuring or building the program. If you have unpacked the source
and built the program without creating any other files, @samp{make
distclean} should leave only the files that were in the distribution.
@item mostlyclean
Like @samp{clean}, but may refrain from deleting a few files that people
normally don't want to recompile. For example, the @samp{mostlyclean}
target for GCC does not delete @file{libgcc.a}, because recompiling it
is rarely necessary and takes a lot of time.
@item maintainer-clean
Delete almost everything from the current directory that can be
reconstructed with this Makefile. This typically includes everything
deleted by @code{distclean}, plus more: C source files produced by
Bison, tags tables, Info files, and so on.
The reason we say ``almost everything'' is that @samp{make
maintainer-clean} should not delete @file{configure} even if
@file{configure} can be remade using a rule in the Makefile. More
generally, @samp{make maintainer-clean} should not delete anything that
needs to exist in order to run @file{configure} and then begin to build
the program. This is the only exception; @code{maintainer-clean} should
delete everything else that can be rebuilt.
The @samp{maintainer-clean} is intended to be used by a maintainer of
the package, not by ordinary users. You may need special tools to
reconstruct some of the files that @samp{make maintainer-clean} deletes.
Since these files are normally included in the distribution, we don't
take care to make them easy to reconstruct. If you find you need to
unpack the full distribution again, don't blame us.
To help make users aware of this, the commands for
@code{maintainer-clean} should start with these two:
@example
@@echo "This command is intended for maintainers to use;"
@@echo "it deletes files that may require special tools to rebuild."
@end example
@item TAGS
Update a tags table for this program.
@item info
Generate any Info files needed. The best way to write the rules is as
follows:
@smallexample
info: foo.info
foo.info: foo.texi chap1.texi chap2.texi
$(MAKEINFO) $(srcdir)/foo.texi
@end smallexample
@noindent
You must define the variable @code{MAKEINFO} in the Makefile. It should
run the @code{makeinfo} program, which is part of the Texinfo
distribution.
@item dvi
Generate DVI files for all TeXinfo documentation.
For example:
@smallexample
dvi: foo.dvi
foo.dvi: foo.texi chap1.texi chap2.texi
$(TEXI2DVI) $(srcdir)/foo.texi
@end smallexample
@noindent
You must define the variable @code{TEXI2DVI} in the Makefile. It should
run the program @code{texi2dvi}, which is part of the Texinfo
distribution. Alternatively, write just the dependencies, and allow GNU
Make to provide the command.
@item dist
Create a distribution tar file for this program. The tar file should be
set up so that the file names in the tar file start with a subdirectory
name which is the name of the package it is a distribution for. This
name can include the version number.
For example, the distribution tar file of GCC version 1.40 unpacks into
a subdirectory named @file{gcc-1.40}.
The easiest way to do this is to create a subdirectory appropriately
named, use @code{ln} or @code{cp} to install the proper files in it, and
then @code{tar} that subdirectory.
The @code{dist} target should explicitly depend on all non-source files
that are in the distribution, to make sure they are up to date in the
distribution.
@xref{Releases, , Making Releases, standards, GNU Coding Standards}.
@item check
Perform self-tests (if any). The user must build the program before
running the tests, but need not install the program; you should write
the self-tests so that they work when the program is built but not
installed.
@end table
The following targets are suggested as conventional names, for programs
in which they are useful.
@table @code
@item installcheck
Perform installation tests (if any). The user must build and install
the program before running the tests. You should not assume that
@file{$(bindir)} is in the search path.
@item installdirs
It's useful to add a target named @samp{installdirs} to create the
directories where files are installed, and their parent directories.
There is a script called @file{mkinstalldirs} which is convenient for
this; find it in the Texinfo package.@c It's in /gd/gnu/lib/mkinstalldirs.
You can use a rule like this:
@comment This has been carefully formatted to look decent in the Make manual.
@comment Please be sure not to make it extend any further to the right.--roland
@smallexample
# Make sure all installation directories (e.g. $(bindir))
# actually exist by making them if necessary.
installdirs: mkinstalldirs
$(srcdir)/mkinstalldirs $(bindir) $(datadir) \
$(libdir) $(infodir) \
$(mandir)
@end smallexample
This rule should not modify the directories where compilation is done.
It should do nothing but create installation directories.
@end table
@node Command Variables
@section Variables for Specifying Commands
Makefiles should provide variables for overriding certain commands, options,
and so on.
In particular, you should run most utility programs via variables.
Thus, if you use Bison, have a variable named @code{BISON} whose default
value is set with @samp{BISON = bison}, and refer to it with
@code{$(BISON)} whenever you need to use Bison.
File management utilities such as @code{ln}, @code{rm}, @code{mv}, and
so on, need not be referred to through variables in this way, since users
don't need to replace them with other programs.
Each program-name variable should come with an options variable that is
used to supply options to the program. Append @samp{FLAGS} to the
program-name variable name to get the options variable name---for
example, @code{BISONFLAGS}. (The name @code{CFLAGS} is an exception to
this rule, but we keep it because it is standard.) Use @code{CPPFLAGS}
in any compilation command that runs the preprocessor, and use
@code{LDFLAGS} in any compilation command that does linking as well as
in any direct use of @code{ld}.
If there are C compiler options that @emph{must} be used for proper
compilation of certain files, do not include them in @code{CFLAGS}.
Users expect to be able to specify @code{CFLAGS} freely themselves.
Instead, arrange to pass the necessary options to the C compiler
independently of @code{CFLAGS}, by writing them explicitly in the
compilation commands or by defining an implicit rule, like this:
@smallexample
CFLAGS = -g
ALL_CFLAGS = -I. $(CFLAGS)
.c.o:
$(CC) -c $(CPPFLAGS) $(ALL_CFLAGS) $<
@end smallexample
Do include the @samp{-g} option in @code{CFLAGS}, because that is not
@emph{required} for proper compilation. You can consider it a default
that is only recommended. If the package is set up so that it is
compiled with GCC by default, then you might as well include @samp{-O}
in the default value of @code{CFLAGS} as well.
Put @code{CFLAGS} last in the compilation command, after other variables
containing compiler options, so the user can use @code{CFLAGS} to
override the others.
Every Makefile should define the variable @code{INSTALL}, which is the
basic command for installing a file into the system.
Every Makefile should also define the variables @code{INSTALL_PROGRAM}
and @code{INSTALL_DATA}. (The default for each of these should be
@code{$(INSTALL)}.) Then it should use those variables as the commands
for actual installation, for executables and nonexecutables
respectively. Use these variables as follows:
@example
$(INSTALL_PROGRAM) foo $(bindir)/foo
$(INSTALL_DATA) libfoo.a $(libdir)/libfoo.a
@end example
@noindent
Always use a file name, not a directory name, as the second argument of
the installation commands. Use a separate command for each file to be
installed.
@node Directory Variables
@section Variables for Installation Directories
Installation directories should always be named by variables, so it is
easy to install in a nonstandard place. The standard names for these
variables are described below. They are based on a standard filesystem
layout; variants of it are used in SVR4, 4.4BSD, Linux, Ultrix v4, and
other modern operating systems.
These two variables set the root for the installation. All the other
installation directories should be subdirectories of one of these two,
and nothing should be directly installed into these two directories.
@table @samp
@item prefix
A prefix used in constructing the default values of the variables listed
below. The default value of @code{prefix} should be @file{/usr/local}
When building the complete GNU system, the prefix will be empty and
@file{/usr} will be a symbolic link to @file{/}.
@item exec_prefix
A prefix used in constructing the default values of some of the
variables listed below. The default value of @code{exec_prefix} should
be @code{$(prefix)}.
Generally, @code{$(exec_prefix)} is used for directories that contain
machine-specific files (such as executables and subroutine libraries),
while @code{$(prefix)} is used directly for other directories.
@end table
Executable programs are installed in one of the following directories.
@table @samp
@item bindir
The directory for installing executable programs that users can run.
This should normally be @file{/usr/local/bin}, but write it as
@file{$(exec_prefix)/bin}.
@item sbindir
The directory for installing executable programs that can be run from
the shell, but are only generally useful to system administrators. This
should normally be @file{/usr/local/sbin}, but write it as
@file{$(exec_prefix)/sbin}.
@item libexecdir
@comment This paragraph adjusted to avoid overfull hbox --roland 5jul94
The directory for installing executable programs to be run by other
programs rather than by users. This directory should normally be
@file{/usr/local/libexec}, but write it as @file{$(exec_prefix)/libexec}.
@end table
Data files used by the program during its execution are divided into
categories in two ways.
@itemize @bullet
@item
Some files are normally modified by programs; others are never normally
modified (though users may edit some of these).
@item
Some files are architecture-independent and can be shared by all
machines at a site; some are architecture-dependent and can be shared
only by machines of the same kind and operating system; others may never
be shared between two machines.
@end itemize
This makes for six different possibilities. However, we want to
discourage the use of architecture-dependent files, aside from of object
files and libraries. It is much cleaner to make other data files
architecture-independent, and it is generally not hard.
Therefore, here are the variables makefiles should use to specify
directories:
@table @samp
@item datadir
The directory for installing read-only architecture independent data
files. This should normally be @file{/usr/local/share}, but write it as
@file{$(prefix)/share}. As a special exception, see @file{$(infodir)}
and @file{$(includedir)} below.
@item sysconfdir
The directory for installing read-only data files that pertain to a
single machine--that is to say, files for configuring a host. Mailer
and network configuration files, @file{/etc/passwd}, and so forth belong
here. All the files in this directory should be ordinary ASCII text
files. This directory should normally be @file{/usr/local/etc}, but
write it as @file{$(prefix)/etc}.
@c rewritten to avoid overfull hbox --tower
Do not install executables
@c here
in this directory (they probably
belong in @file{$(libexecdir)} or @file{$(sbindir))}. Also do not
install files that are modified in the normal course of their use
(programs whose purpose is to change the configuration of the system
excluded). Those probably belong in @file{$(localstatedir)}.
@item sharedstatedir
The directory for installing architecture-independent data files which
the programs modify while they run. This should normally be
@file{/usr/local/com}, but write it as @file{$(prefix)/com}.
@item localstatedir
The directory for installing data files which the programs modify while
they run, and that pertain to one specific machine. Users should never
need to modify files in this directory to configure the package's
operation; put such configuration information in separate files that go
in @file{datadir} or @file{$(sysconfdir)}. @file{$(localstatedir)}
should normally be @file{/usr/local/var}, but write it as
@file{$(prefix)/var}.
@item libdir
The directory for object files and libraries of object code. Do not
install executables here, they probably belong in @file{$(libexecdir)}
instead. The value of @code{libdir} should normally be
@file{/usr/local/lib}, but write it as @file{$(exec_prefix)/lib}.
@item infodir
The directory for installing the Info files for this package. By
default, it should be @file{/usr/local/info}, but it should be written
as @file{$(prefix)/info}.
@item includedir
@c rewritten to avoid overfull hbox --roland
The directory for installing header files to be included by user
programs with the C @samp{#include} preprocessor directive. This
should normally be @file{/usr/local/include}, but write it as
@file{$(prefix)/include}.
Most compilers other than GCC do not look for header files in
@file{/usr/local/include}. So installing the header files this way is
only useful with GCC. Sometimes this is not a problem because some
libraries are only really intended to work with GCC. But some libraries
are intended to work with other compilers. They should install their
header files in two places, one specified by @code{includedir} and one
specified by @code{oldincludedir}.
@item oldincludedir
The directory for installing @samp{#include} header files for use with
compilers other than GCC. This should normally be @file{/usr/include}.
The Makefile commands should check whether the value of
@code{oldincludedir} is empty. If it is, they should not try to use
it; they should cancel the second installation of the header files.
A package should not replace an existing header in this directory unless
the header came from the same package. Thus, if your Foo package
provides a header file @file{foo.h}, then it should install the header
file in the @code{oldincludedir} directory if either (1) there is no
@file{foo.h} there or (2) the @file{foo.h} that exists came from the Foo
package.
To tell whether @file{foo.h} came from the Foo package, put a magic
string in the file---part of a comment---and grep for that string.
@end table
Unix-style man pages are installed in one of the following:
@table @samp
@item mandir
The directory for installing the man pages (if any) for this package.
It should include the suffix for the proper section of the
manual---usually @samp{1} for a utility. It will normally be
@file{/usr/local/man/man1}, but you should write it as
@file{$(prefix)/man/man1}.
@item man1dir
The directory for installing section 1 man pages.
@item man2dir
The directory for installing section 2 man pages.
@item @dots{}
Use these names instead of @samp{mandir} if the package needs to install man
pages in more than one section of the manual.
@strong{Don't make the primary documentation for any GNU software be a
man page. Write a manual in Texinfo instead. Man pages are just for
the sake of people running GNU software on Unix, which is a secondary
application only.}
@item manext
The file name extension for the installed man page. This should contain
a period followed by the appropriate digit; it should normally be @samp{.1}.
@item man1ext
The file name extension for installed section 1 man pages.
@item man2ext
The file name extension for installed section 2 man pages.
@item @dots{}
Use these names instead of @samp{manext} if the package needs to install man
pages in more than one section of the manual.
@end table
And finally, you should set the following variable:
@table @samp
@item srcdir
The directory for the sources being compiled. The value of this
variable is normally inserted by the @code{configure} shell script.
@end table
For example:
@smallexample
@c I have changed some of the comments here slightly to fix an overfull
@c hbox, so the make manual can format correctly. --roland
# Common prefix for installation directories.
# NOTE: This directory must exist when you start the install.
prefix = /usr/local
exec_prefix = $(prefix)
# Where to put the executable for the command `gcc'.
bindir = $(exec_prefix)/bin
# Where to put the directories used by the compiler.
libexecdir = $(exec_prefix)/libexec
# Where to put the Info files.
infodir = $(prefix)/info
@end smallexample
If your program installs a large number of files into one of the
standard user-specified directories, it might be useful to group them
into a subdirectory particular to that program. If you do this, you
should write the @code{install} rule to create these subdirectories.
Do not expect the user to include the subdirectory name in the value of
any of the variables listed above. The idea of having a uniform set of
variable names for installation directories is to enable the user to
specify the exact same values for several different GNU packages. In
order for this to be useful, all the packages must be designed so that
they will work sensibly when the user does so.

.TH MAKE 1L "22 August 1989" "GNU" "LOCAL USER COMMANDS"
.SH NAME
make \- GNU make utility to maintain groups of programs
.SH SYNOPSIS
.B "make "
[
.B \-f
makefile ] [ option ] ...
target ...
.SH WARNING
This man paage is an extract of the documentation of
.I GNU make .
It is updated only occasionally, because the GNU project does not use nroff.
For complete, current documentation, refer to the Info file
.B make
or the DVI file
.B make.dvi
which are made from the Texinfo source file
.BR make.texinfo .
.SH DESCRIPTION
.LP
The purpose of the
.I make
utility is to determine automatically which
pieces of a large program need to be recompiled, and issue the commands to
recompile them.
This manual describes the GNU implementation of
.IR make ,
which was written by Richard Stallman and Roland McGrath.
Our examples show C programs, since they are most common, but you can use
.I make
with any programming language whose compiler can be run with a
shell command.
In fact,
.I make
is not limited to programs.
You can use it to describe any task where some files must be
updated automatically from others whenever the others change.
.LP
To prepare to use
.IR make ,
you must write a file called the
.I makefile
that describes the relationships among files in your program, and the
states the commands for updating each file.
In a program, typically the executable file is updated from object
files, which are in turn made by compiling source files.
.LP
Once a suitable makefile exists, each time you change some source files,
this simple shell command:
.sp 1
.RS
.B make
.RE
.sp 1
suffices to perform all necessary recompilations.
The
.I make
program uses the makefile data base and the last-modification times
of the files to decide which of the files need to be updated.
For each of those files, it issues the commands recorded in the data base.
.LP
.I make
executes commands in the
.I makefile
to update
one or more target
.IR names ,
where
.I name
is typically a program.
If no
.B \-f
option is present,
.I make
will look for the makefiles
.IR GNUmakefile ,
.IR makefile ,
and
.IR Makefile ,
in that order.
.LP
Normally you should call your makefile either
.I makefile
or
.IR Makefile .
(We recommend
.I Makefile
because it appears prominently near the beginning of a directory
listing, right near other important files such as
.IR README .)
The first name checked,
.IR GNUmakefile ,
is not recommended for most makefiles.
You should use this name if you have a makefile that is specific to GNU
.IR make ,
and will not be understood by other versions of
.IR make .
If
.I makefile
is `\-', the standard input is read.
.LP
.I make
updates a target if it depends on prerequisite files
that have been modified since the target was last modified,
or if the target does not exist.
.SH OPTIONS
.sp 1
.TP 0.5i
.B \-b
.TP 0.5i
.B \-m
These options are ignored for compatibility with other versions of
.IR make .
.TP 0.5i
.BI "\-C " dir
Change to directory
.I dir
before reading the makefiles or doing anything else.
If multiple
.B \-C
options are specified, each is interpreted relative to the
previous one:
.BR "\-C " /
.BR "\-C " etc
is equivalent to
.BR "\-C " /etc.
This is typically used with recursive invocations of
.IR make .
.TP 0.5i
.B \-d
Print debugging information in addition to normal processing.
The debugging information says which files are being considered for
remaking, which file-times are being compared and with what results,
which files actually need to be remade, which implicit rules are
considered and which are applied---everything interesting about how
.I make
decides what to do.
.TP 0.5i
.B \-e
Give variables taken from the environment precedence
over variables from makefiles.
.TP 0.5i
.BI "\-f " file
Use
.I file
as a makefile.
.TP 0.5i
.B \-i
Ignore all errors in commands executed to remake files.
.TP 0.5i
.BI "\-I " dir
Specifies a directory
.I dir
to search for included makefiles.
If several
.B \-I
options are used to specify several directories, the directories are
searched in the order specified.
Unlike the arguments to other flags of
.IR make ,
directories given with
.B \-I
flags may come directly after the flag:
.BI \-I dir
is allowed, as well as
.BI "\-I " dir.
This syntax is allowed for compatibility with the C
preprocessor's
.B \-I
flag.
.TP 0.5i
.BI "\-j " jobs
Specifies the number of jobs (commands) to run simultaneously.
If there is more than one
.B \-j
option, the last one is effective.
If the
.B \-j
option is given without an argument,
.IR make
will not limit the number of jobs that can run simultaneously.
.TP 0.5i
.B \-k
Continue as much as possible after an error.
While the target that failed, and those that depend on it, cannot
be remade, the other dependencies of these targets can be processed
all the same.
.TP 0.5i
.B \-l
.TP 0.5i
.BI "\-l " load
Specifies that no new jobs (commands) should be started if there are
others jobs running and the load average is at least
.I load
(a floating-point number).
With no argument, removes a previous load limit.
.TP 0.5i
.B \-n
Print the commands that would be executed, but do not execute them.
.TP 0.5i
.BI "\-o " file
Do not remake the file
.I file
even if it is older than its dependencies, and do not remake anything
on account of changes in
.IR file .
Essentially the file is treated as very old and its rules are ignored.
.TP 0.5i
.B \-p
Print the data base (rules and variable values) that results from
reading the makefiles; then execute as usual or as otherwise
specified.
This also prints the version information given by the
.B \-v
switch (see below).
To print the data base without trying to remake any files, use
.B make
.B \-p
.BI \-f /dev/null.
.TP 0.5i
.B \-q
``Question mode''.
Do not run any commands, or print anything; just return an exit status
that is zero if the specified targets are already up to date, nonzero
otherwise.
.TP 0.5i
.B \-r
Eliminate use of the built-in implicit rules.
Also clear out the default list of suffixes for suffix rules.
.TP 0.5i
.B \-s
Silent operation; do not print the commands as they are executed.
.TP 0.5i
.B \-S
Cancel the effect of the
.B \-k
option.
This is never necessary except in a recursive
.I make
where
.B \-k
might be inherited from the top-level
.I make
via MAKEFLAGS or if you set
.B \-k
in MAKEFLAGS in your environment.
.TP 0.5i
.B \-t
Touch files (mark them up to date without really changing them)
instead of running their commands.
This is used to pretend that the commands were done, in order to fool
future invocations of
.IR make .
.TP 0.5i
.B \-v
Print the version of the
.I make
program plus a copyright, a list of authors and a notice that there
is no warranty.
After this information is printed, processing continues normally.
To get this information without doing anything else, use
.B make
.B \-v
.BI \-f /dev/null.
.TP 0.5i
.B \-w
Print a message containing the working directory
before and after other processing.
This may be useful for tracking down errors from complicated nests of
recursive
.I make
commands.
.TP 0.5i
.BI "\-W " file
Pretend that the target
.I file
has just been modified.
When used with the
.B \-n
flag, this shows you what would happen if you were to modify that file.
Without
.BR \-n ,
it is almost the same as running a
.I touch
command on the given file before running
.IR make ,
except that the modification time is changed only in the imagination of
.IR make .
