= Introduction =

/!\ ***Note to document writers:*** Please use this document as the central
place for describing build procefures. Please do not remove this notice. 

/!\ ***Note:*** This is a 'cut and paste' tutorial - in most cases you can
simply copy the commands listed in codeblocks that look like this:

``` somecommand to be pasted ```


= General Build Note =

At version 0.8.1 QGIS no longer uses the autotools for building. QGIS, like a
number of major projects (eg. KDE 4.0), now uses cmake for building from
source. The configure script in this directory simply checks for the existence
of cmake and provides some clues to build QGIS.

For complete information, see the wiki at:
   http://wiki.qgis.org/qgiswiki/Building_with_CMake

= Building under windows using msys =

== MSYS: ==

MSYS provides a unix style build environment under windows. We have created a
zip archive that contains just about all dependencies.

Get this: 

http://qgis.org/uploadfiles/msys/msys.tar.gz

and unpack to c:\msys


/!\ The file above is compressed as gzipped tarball - you can get a free
windows application for creating and decompressing files here:

http://www.7-zip.org/

If you wish to prepare your msys environment yourself rather than using 
our pre-made one, detailed instructions are provdided elsewhere in this
document.

== Qt4.3 ==

Download qt4.3 opensource precompiled edition exe and install (including the
download and install of mingw) from here:

http://www.trolltech.com/developer/downloads/qt/windows

When the installer will ask for MinGW, you don't need to download and install
it, just point the installer to c:\msys\mingw

When Qt installation is complete:

Edit C:\Qt\4.3.0\bin\qtvars.bat and add the following lines:

``` 
set PATH=%PATH%;C:\msys\local\bin;c:\msys\local\lib 
set PATH=%PATH%;"C:\Program Files\Subversion\bin" 
```

I suggest you also add C:\Qt\4.3.0\bin\ to your Environment Variables Path in
the windows system preferences.

If you plan to do some debugging, you'll need to compile debug version of Qt:
C:\Qt\4.3.0\bin\qtvars.bat compile_debug

Note: there is a problem when compiling debug version of Qt 4.3, the script ends with
this message  "mingw32-make: *** No rule to make target `debug'.  Stop.". To 
compile the debug version you have to go out of src directory and execute the
following command:

``` 
c:\Qt\4.3.0 make 
```


== Flex and Bison ==

*** Note I think this section can be removed as it should be installed int the
msys image already. TS

Get Flex
http://sourceforge.net/project/showfiles.php?group_id=23617&package_id=16424
(the zip bin) and extract it into c:\msys\mingw\bin

== Python stuff: (optional) ==


Follow this section in case you would like to use Python bindings for QGIS.  To
be able to compile bindings, you need to compile SIP and PyQt4 from sources as
their installer doesn't include some development files which are necessary.

=== Download and install Python - use Windows installer ===

(It doesn't matter to what folder you'll install it)

http://python.org/download/

=== Download SIP and PyQt4 sources ===

http://www.riverbankcomputing.com/Downloads/sip4/sip-4.6.zip
http://www.riverbankcomputing.com/Downloads/PyQt4/GPL/PyQt-win-gpl-4.2.zip

Extract each of the above zip files in a temporary directory.
   
=== Compile SIP ===

``` 
c:\Qt\4.3.0\bin\qtvars.bat 
python configure.py -p win32-g++ 
make 
make install 
```

=== Compile PyQt ===

``` 
c:\Qt\4.3.0\bin\qtvars.bat 
python configure.py 
make 
make install 
```


=== Final python notes ===

/!\ You can delete the directories with unpacked SIP and PyQt4 sources after a
successfull install, they're not needed anymore.

== Subversion: ==

In order to check out QGIS sources from the repository, you need Subversion
client. This installer should work fine:

http://subversion.tigris.org/files/documents/15/36797/svn-1.4.3-setup.exe


== CMake: ==

CMake is build system used by Quantum GIS. Download it from here:

http://www.cmake.org/files/v2.4/cmake-2.4.6-win32-x86.exe


== QGIS: ==

Start a cmd.exe window ( Start -> Run -> cmd.exe ) Create development 
directory and move into it

``` 
md c:\dev\cpp 
cd c:\dev\cpp 
```
   
Check out sources from SVN For svn head:
``` 
svn co https://svn.qgis.org/repos/qgis/trunk/qgis 
```
For svn 0.8 branch
```
 svn co https://svn.qgis.org/repos/qgis/branches/Release-0_8_0 qgis0.8
```


== Compiling: ==

As a background read the generic building with CMake notes at the end of 
this document.

Start a cmd.exe window ( Start -> Run -> cmd.exe ) if you don't have one
already.  Add paths to compiler and our MSYS environment:
  
``` 
c:\Qt\4.3.0\bin\qtvars.bat 
```

For ease of use add c:\Qt\4.3.0\bin\ to your system path in system
properties so you can just type qtvars.bat when you open the cmd console.
Create build directory and set it as current directory:


``` 
cd c:\dev\cpp\qgis 
md build 
cd build 
```

== Configuration ==

```
cmakesetup ..  
```

/!\ NOTE: You must include the '..' above.

Click 'Configure' button.  When asked, you should choose 'MinGW Makefiles'
as generator.

There's a problem with MinGW Makefiles on Win2K. If you're compiling on this
platform, use 'MSYS Makefiles' generator instead.

All dependencies should be picked up automatically, if you have set up the
Paths correctly. The only thing you need to change is the installation
destination (CMAKE_INSTALL_PREFIX) and/or set 'Debug'.

For compatibility with NSIS packaging cripts I recommend to leave the
install prefix to its default c:\program files\

When configuration is done, click 'OK' to exit the setup utility.

== Compilation and installation ==
 
 
``` 
 make make install 
```

== Run qgis.exe from the directory where it's installed (CMAKE_INSTALL_PREFIX) ==

Make sure to copy all .dll:s needed to the same directory as the qgis.exe
binary is installed to, if not already done so, otherwise QGIS will complain
about missing libraries when started.

The best way to do this is to download both the QGIS current release installer
package from http://qgis.org/uploadfiles/testbuilds/ and install it. Now copy
the installation dir from C:\Program Files\Quantum GIS into c:\Program
Files\qgis-0.8.1 (or whatever the current version is. The name should strictly
match the version no.) After making this copy you can uninstall the release
version of QGIS from your c:\Program Files directory using the provided
uninstaller. Double check that the Quantum GIS dir is completely gone under
program files afterwards.
   
Another possibility is to run qgis.exe when your path contains
c:\msys\local\bin and c:\msys\local\lib directories, so the DLLs will be
used from that place.


== Create the installation package: (optional) ==

Downlad and install NSIS from (http://nsis.sourceforge.net/Main_Page)


Now using windows explorer, enter the win_build directory in your QGIS source
tree. Read the READMEfile there and follow the instructions. Next right click
on qgis.nsi and choose the option 'Compile NSIS Script'. 



= Building on Mac OSX using frameworks and cmake (QGIS > 0.8) =


In this approach I will try to avoid as much as possible building dependencies
from source and rather use frameworks wherever possible.

== Install XCODE ==

I recommend to get the latest xcode dmg from the Apple XDC Web site. Install
XCODE after the ~941mb download is complete.

== Install Qt4 from .dmg ==

``` 
ftp://ftp.trolltech.com/qt/source/qt-mac-opensource-4.2.3.dmg 
```

If you want debug libs, Qt also provide a dmg with these:

``` 
ftp://ftp.trolltech.com/qt/source/qt-mac-opensource-4.2.3-debug-libs.dmg
```

I am going to proceed using only release libs at this stage as the download for
the debug dmg is substantially bigger. If you plan to do any debugging though
you probably want to get the debug libs dmg. Once downloaded open the dmg and
run the installer. Note you need admin access to install.

After installing you need to make two small changes:

First edit ``/Library/Frameworks/QtCore.framework/Headers/qconfig.h`` and
change 

/!\ Note this doesnt seem to be needed since version 4.2.3

``QT_EDITION_UNKNOWN`` to ``QT_EDITION_OPENSOURCE``

Second change the default mkspec symlink so that it points to macx-g++:

```
cd /usr/local/Qt4.2/mkspecs/ sudo rm default sudo ln -sf macx-g++ default
```


== Install development frameworks for QGIS dependencies ==

Download William Kyngesburye's excellent all in one framework that includes
proj, gdal, sqlite3 etc

``` 
http://www.kyngchaos.com/files/software/unixport/AllFrameworks.dmg 
```

Once downloaded, open and install the frameworks.

William provides an additional installer package for Postgresql/PostGIS. Its
available here:

``` 
http://www.kyngchaos.com/software/unixport/postgres 
```

There are some additional dependencies that at the time of writing are not
provided as frameworks so we will need to build these from source.

=== Additional Dependencies : GSL ===

Retrieve the Gnu Scientific Library from

``` 
curl -O ftp://ftp.gnu.org/gnu/gsl/gsl-1.8.tar.gz 
```

Then extract it and build it to a prefix of /usr/local:

``` 
tar xvfz gsl-1.8.tar.gz 
cd gsl-1.8 
./configure --prefix=/usr/local 
make
sudo make install cd ..  
```

=== Additional Dependencies : Expat ===

Get the expat sources:

``` 
http://sourceforge.net/project/showfiles.php?group_id=10127 
```

```
tar xvfz expat-2.0.0.tar.gz 
cd expat-2.0.0 
./configure --prefix=/usr/local
make 
sudo make install 
cd ..  
```

=== Additional Dependencies : SIP ===

Retrieve the python bindings toolkit SIP from

``` 
curl -O http://www.riverbankcomputing.com/Downloads/sip4/sip-4.5.2.tar.gz
```

Then extract and build it to a prefix of /usr/local:

``` 
tar xvfz sip-4.5.2.tar.gz 
cd sip-4.5.2 
python configure.py 
make 
sudo make install 
cd ..  
```

=== Additional Dependencies : PyQt ===

Retrieve the python bindings toolkit for Qt from

``` 
curl -O http://www.riverbankcomputing.com/Downloads/PyQt4/GPL/PyQt-mac-gpl-4.1.1.tar.gz
```

Then extract and build it to a prefix of /usr/local:

``` 
tar xvfz PyQt-mac-gpl-4.1.1.tar.gz 
cd PyQt-mac-gpl-4.1.1 
python configure.py 
yes 
make 
sudo make install 
cd ..  
```

=== Additional Dependencies : Bison ===

The version of bison available by default on Mac OSX is too old so you need to
get a more recent one on your system. Download if from:

``` 
curl -O http://ftp.gnu.org/gnu/bison/bison-2.3.tar.gz 
```

Now build and install it to a prefix of /usr/local :

``` 
tar xvfz bison-2.3.tar.gz 
cd bison-2.3 
./configure --prefix=/usr/local 
make
sudo make install 
cd ..  
```

== Install CMAKE for OSX ==

Get the latest release from here:

``` 
http://www.cmake.org/HTML/Download.html 
```

At the time of writing the file I grabbed was:

``` 
curl -O http://www.cmake.org/files/v2.4/cmake-2.4.6-Darwin-universal.dmg
```

Once downloaded open the dmg and run the installer

== Install subversion for OSX ==

The [http://sourceforge.net/projects/macsvn/ MacSVN] project has a downloadable
build of svn. If you are a GUI inclined person you may want to grab their gui
client too. Get the command line client here:

``` 
curl -O http://ufpr.dl.sourceforge.net/sourceforge/macsvn/Subversion_1.4.2.zip 
```


Once downloaded open the zip file and run the installer.

You also need to install BerkleyDB available from the same
[http://sourceforge.net/projects/macsvn/ website]. At the time of writing the
file was here:

``` 
curl -O http://ufpr.dl.sourceforge.net/sourceforge/macsvn/Berkeley_DB_4.5.20.zip 
```

Once again unzip this and run the installer therein.

Lastly we need to ensure that the svn commandline executeable is in the path.
Add the following line to the end of /etc/bashrc using sudo:

``` 
sudo vim /etc/bashrc 
```

And add this line to the bottom before saving and quiting:

``` 
export PATH=/usr/local/bin:$PATH:/usr/local/pgsql/bin 
```

/usr/local/bin needs to be first in the path so that the newer bison (that will
be built from source further down) is found before the bison (which is very
old) that is installed by MacOSX


Now close and reopen your shell to get the updated vars.

== Check out QGIS from SVN ==

Now we are going to check out the sources for QGIS. First we will create a
directory for working in:

``` 
mkdir -p ~/dev/cpp cd ~/dev/cpp 
```

Now we check out the sources:

Trunk:
``` 
svn co https://svn.qgis.org/repos/qgis/trunk/qgis qgis 
```

For svn 0.8 branch
``` 
svn co https://svn.qgis.org/repos/qgis/branches/Release-0_8_0 qgis0.8
```


The first time you check out QGIS sources you will probably get a message like
this:

``` 
 Error validating server certificate for 'https://svn.qgis.org:443':
 - The certificate is not issued by a trusted authority. Use the fingerprint to
   validate the certificate manually!  Certificate information:
 - Hostname: svn.qgis.org
 - Valid: from Apr  1 00:30:47 2006 GMT until Mar 21 00:30:47 2008 GMT
 - Issuer: Developer Team, Quantum GIS, Anchorage, Alaska, US
 - Fingerprint: 2f:cd:f1:5a:c7:64:da:2b:d1:34:a5:20:c6:15:67:28:33:ea:7a:9b
   (R)eject, accept (t)emporarily or accept (p)ermanently?  
```

I suggest you press 'p' to accept the key permanently.

== Configure the build ==

CMake supports out of source build so we will create a 'build' dir for the
build process

``` 
cd qgis 
mkdir build 
cd build 
cmake -D CMAKE_INSTALL_PREFIX=$HOME/apps/ -D CMAKE_BUILD_TYPE=Release..
```

To use a specific GRASS version, You can optionally use the following 
cmake invocation (with modifications to suite your system (thanks William 
Kyngesburye for this hint):

```
cmake -D CMAKE_INSTALL_PREFIX=$HOME/apps/ \
      -D GRASS_INCLUDE_DIR=/Applications/GRASS-6.3.app/Contents/Resources/include \
      -D GRASS_PREFIX=/Applications/GRASS-6.3.app/Contents/Resources \
      -D CMAKE_BUILD_TYPE=Release \
      ..
```

== GEOS Issues ==

I had some issues with GEOS headers so I made the following edits:

In file /Library/Frameworks/GEOS.framework/Headers/io.h, comment out line 61

In file /Library/Frameworks/GEOS.framework/Headers/geom.h, comment out line 145

== Building ==

Now we can start the build process:

``` 
make 
```

If all built without errors you can then install it:

``` 
make install 
```

= Building on GNU/Linux =

== Building QGIS with Qt4.x ==

***Requires:*** Ubuntu Edgy / Debian derived distro

These notes are for if you want to build QGIS from source. One of the major
aims here is to show how this can be done using binary packages for ***all***
dependencies - building only the core QGIS stuff from source. I prefer this
approach because it means we can leave the business of managing system packages
to apt and only concern ourselves with coding QGIS! 

This document assumes you have made a fresh install and have a 'clean' system.
These instructions should work fine if this is a system that has already been
in use for a while, you may need to just skip those steps which are irrelevant
to you.



== Prepare apt ==

The packages qgis depends on to build are available in the "universe" component
of Ubuntu. This is not activated by default, so you need to activate it:

1. Edit your /etc/apt/sources.list file.  
2. Uncomment the all the lines starting with "deb"

Also you will need to be running (K)Ubuntu 'edgy' or higher in order for 
all dependencies to be met.

Now update your local sources database:

``` 
sudo apt-get update 
```


== Install Qt4 ==

``` 
sudo apt-get install libqt4-core libqt4-debug  \
libqt4-dev libqt4-gui libqt4-qt3support libqt4-sql lsb-qt4 qt4-designer \
qt4-dev-tools qt4-doc qt4-qtconfig uim-qt gcc libapt-pkg-perl resolvconf
```

/!\ ***A Special Note:*** If you are following this set of instructions on
a system where you already have Qt3 development tools installed, there will
be a conflict between Qt3 tools and Qt4 tools. For example, qmake will
point to the Qt3 version not the Qt4. Ubuntu Qt4 and Qt3 packages are
designed to live alongside each other. This means that for example if you
have them both installed you will have three qmake exe's:

``` 
/usr/bin/qmake -> /etc/alternatives/qmake 
/usr/bin/qmake-qt3
/usr/bin/qmake-qt4 
```

The same applies to all other Qt binaries. You will notice above that the
canonical 'qmake' is managed by apt alternatives, so before we start to
build QGIS, we need to make Qt4 the default. To return Qt3 to default later
you can use this same process.

You can use apt alternatives to correct this so that the Qt4 version of
applications is used in all cases:

``` 
sudo update-alternatives --config qmake
sudo update-alternatives --config uic 
sudo update-alternatives --config designer 
sudo update-alternatives --config assistant 
sudo update-alternatives --config qtconfig 
sudo update-alternatives --config moc 
sudo update-alternatives --config lupdate 
sudo update-alternatives --config lrelease 
sudo update-alternatives --config linguist 
```

Use the simple command line dialog that appears after running each of the
above commands to select the Qt4 version of the relevant applications.

== Install additional software dependencies required by QGIS ==

``` 
sudo apt-get install gdal-bin libgdal1-dev libgeos-dev proj libtool \
libgdal-doc libhdf4g-dev libhdf4g-run python-dev \
swig libgsl0-dev g++ libjasper-1.701-dev libtiff4-dev subversion gsl-bin \
libsqlite3-dev sqlite3 ccache make libpq-dev flex bison cmake txt2tags \
python-qt4 python-qt4-dev python-sip4 sip4
```

/!\ Debian users should use libgdal-dev above rather

/!\ ***Note:*** For python language bindings SIP >= 4.5 and PyQt4 >= 4.1 is required! Some stable GNU/Linux
distributions (e.g. Debian or SuSE) only provide SIP < 4.5 and PyQt4 < 4.1. To include support for python 
language bindings you may need to build and install those packages from source.


== GRASS Specific Steps ==

/!\ ***Note:*** If you don't need to build with GRASS support,  you can
skip this section.

Now you can install grass from dapper:

```
sudo apt-get install grass libgrass-dev libgdal1-grass 
```

/!\ You may need to explicitly state your grass version e.g. libgdal1-1.3.2-grass

== Setup ccache (Optional) ==

You should also setup ccache to speed up compile times:

``` 
cd /usr/local/bin 
sudo ln -s /usr/bin/ccache gcc 
sudo ln -s /usr/bin/ccache g++ 
```

== Prepare your development environment ==

As a convention I do all my development work in $HOME/dev/<language>, so in
this case we will create a work environment for C++ development work like
this:

``` 
mkdir -p ${HOME}/dev/cpp 
cd ${HOME}/dev/cpp 
```

This directory path will be assumed for all instructions that follow.


== Check out the QGIS Source Code ==

There are two ways the source can be checked out. Use the anonymous method
if you do not have edit privaleges for the QGIS source repository, or use
  the developer checkout if you have permissions to commit source code
  changes.

1. Anonymous Checkout

``` 
cd ${HOME}/dev/cpp 
svn co https://svn.qgis.org/repos/qgis/trunk/qgis qgis
```

2. Developer Checkout

``` 
cd ${HOME}/dev/cpp 
svn co --username <yourusername> https://svn.qgis.org/repos/qgis/trunk/qgis qgis 
```

The first time you check out the source you will be prompted to accept the
qgis.org certificate. Press 'p' to accept it permanently:

``` 
Error validating server certificate for 'https://svn.qgis.org:443':
   - The certificate is not issued by a trusted authority. Use the
     fingerprint to validate the certificate manually!  Certificate
     information:
   - Hostname: svn.qgis.org
   - Valid: from Apr  1 00:30:47 2006 GMT until Mar 21 00:30:47 2008 GMT
   - Issuer: Developer Team, Quantum GIS, Anchorage, Alaska, US
   - Fingerprint:
     2f:cd:f1:5a:c7:64:da:2b:d1:34:a5:20:c6:15:67:28:33:ea:7a:9b (R)eject,
     accept (t)emporarily or accept (p)ermanently?  
```

== Starting the compile ==

I compile my development version of QGIS into my ~/apps directory to avoid
conflicts with Ubuntu packages that may be under /usr. This way for example
you can use the binary packages of QGIS on your system along side with your
development version. I suggest you do something similar:

``` 
mkdir -p ${HOME}/apps 
```

Now we create a build directory and run ccmake:

```
cd qgis
mkdir build
cd build
ccmake ..
```

When you run ccmake (note the .. is required!), a menu will appear where 
you can configure various aspects of the build. If you do not have root
access or do not want to overwrite existing QGIS installs (by your
packagemanager for example), set the CMAKE_BUILD_PREFIX to somewhere you
have write access to (I usually use /home/timlinux/apps). Now press
'c' to configure, 'e' to dismiss any error messages that may appear.
and 'g' to generate the make files. Note that sometimes 'c' needs to 
be pressed several times before the 'g' option becomes available.
After the 'g' generation is complete, press 'q' to exit the ccmake 
interactive dialog.

Now on with the build:

```
make
make install
```

It may take a little while to build depending on your platform.

== Running QGIS ==

Now you can try to run QGIS:

``` 
$HOME/apps/bin/qgis 
```

If all has worked properly the QGIS application should start up and appear
on your screen.

= Creation of MSYS environment for compilation of Quantum GIS =

== Initial setup ==

=== MSYS ===

This is the environment that supplies many utilities from UNIX world in Windows and is needed
by many dependencies to be able to compile.

Download from here:
	http://puzzle.dl.sourceforge.net/sourceforge/mingw/MSYS-1.0.11-2004.04.30-1.exe

Install to ``c:\msys``

All stuff we're going to compile is going to get to this directory (resp. its subdirs).

=== MinGW ===

Download from here:
	http://puzzle.dl.sourceforge.net/sourceforge/mingw/MinGW-5.1.3.exe

Install to ``c:\msys\mingw``

It suffices to download and install only ``g++`` and ``mingw-make`` components.

=== Flex and Bison ===

Flex and Bison are tools for generation of parsers, they're needed for GRASS and also QGIS compilation.

Download the following packages:
	http://gnuwin32.sourceforge.net/downlinks/flex-bin-zip.php
	
	http://gnuwin32.sourceforge.net/downlinks/bison-bin-zip.php
	
	http://gnuwin32.sourceforge.net/downlinks/bison-dep-zip.php

Unpack them all to ``c:\msys\local``


== Installing dependencies == 
 
=== Getting ready ===

Paul Kelly did a great job and prepared a package of precompiled libraries for GRASS.
The package currently includes:

- zlib-1.2.3
- libpng-1.2.16-noconfig
- xdr-4.0-mingw2
- freetype-2.3.4
- fftw-2.1.5
- PDCurses-3.1
- proj-4.5.0
- gdal-1.4.1


It's available for download here:
	http://www.stjohnspoint.co.uk/grass/wingrass-extralibs.tar.gz

Moreover he also left the notes how to compile it (for those interested):
	http://www.stjohnspoint.co.uk/grass/README.extralibs

Unpack the whole package to ``c:\msys\local``


=== GDAL level one ===

Since Quantum GIS needs GDAL with GRASS support, we need to compile GDAL
from source - Paul Kelly's package doesn't include GRASS support in GDAL.
The idea is following:
+ compile GDAL without GRASS
+ compile GRASS
+ compile GDAL with GRASS


So, start with downloading GDAL sources:
	http://download.osgeo.org/gdal/gdal141.zip

Unpack it to some directory, preferably ``c:\msys\local\src``.

Start MSYS console, go to gdal-1.4.1 directory and run the commands below.
You can put them all to a script, e.g. build-gdal.sh and run them at once.
The recipe is taken from Paul Kelly's instructions - basically they
just make sure that the library will be created as DLL and the utility
programs will be dynamically linked to it...

```
CFLAGS="-O2 -s" CXXFLAGS="-O2 -s" LDFLAGS=-s ./configure --without-libtool --prefix=/usr/local --enable-shared --disable-static --with-libz=/usr/local --with-png=/usr/local

```

Finally, manually edit ``gdal-config`` in ``c:\msys\local\bin`` to replace the static library reference with -lgdal:
```
CONFIG_LIBS="-L/usr/local/lib -lpng -lz -lgdal"
```
GDAL build procedure can be greatly simplified to use libtool with a libtool line patch:
configure gdal as below:
./configure --with-ngpython --with-xerces=/local/ --with-jasper=/local/ --with-grass=/local/grass-6.3.cvs/ --with-pg=/local/pgsql/bin/pg_config.exe 

Then fix libtool with:
mv libtool libtool.orig
cat libtool.orig | sed 's/max_cmd_len=8192/max_cmd_len=32768/g' > libtool

Libtool on windows assumes a line length limit of 8192 for some reason and tries to page the linking and fails miserably. This is a work around.

Make and make install should be hassle free after this.

=== GRASS ===

Grab sources from CVS or use a weekly snapshot, see:
	http://grass.itc.it/devel/cvs.php

In MSYS console go to the directory where you've unpacked or checked out sources
(e.g. ``c:\msys\local\src\grass-6.3.cvs``)

Run these commands:
```
export PATH="/usr/local/bin:/usr/local/lib:$PATH"
./configure --prefix=/usr/local --bindir=/usr/local --with-includes=/usr/local/include --with-libs=/usr/local/lib --with-cxx --without-jpeg --without-tiff --without-postgres --with-opengl=windows --with-fftw --with-freetype --with-freetype-includes=/usr/local/include/freetype2 --without-x --without-tcltk --enable-x11=no --enable-shared=yes --with-proj-share=/usr/local/share/proj
make
make install
```

It should get installed to ``c:\msys\local\grass-6.3.cvs``

By the way, these pages might be useful:
- http://grass.gdf-hannover.de/wiki/WinGRASS_Current_Status
- http://geni.ath.cx/grass.html


=== GDAL level two ===

At this stage, we'll use GDAL sources we've used before, only the compilation will be a bit different.

But first in order to be able to compile GDAL sources with current GRASS CVS, you need to patch them, here's what you need to change:
	http://trac.osgeo.org/gdal/attachment/ticket/1587/plugin_patch_grass63.diff
(you can patch it by hand or use patch.exe in ``c:\msys\bin``)

Now in MSYS console go to the GDAL sources directory and run the same commands as in level one, only with these differences:

+ when running ``./configure`` add this argument: ``--with-grass=/usr/local/grass-6.3.cvs``
+ when calling ``g++`` on line 5 (which creates libgdal.dll), add these arguments: ``-L/usr/local/grass-6.3.cvs/lib -lgrass_vect -lgrass_dig2 -lgrass_dgl -lgrass_rtree -lgrass_linkm -lgrass_dbmiclient -lgrass_dbmibase -lgrass_I -lgrass_gproj -lgrass_vask -lgrass_gmath -lgrass_gis -lgrass_datetime``


Then again, edit ``gdal-config`` and change line with CONFIG_LIBS
```
CONFIG_LIBS="-L/usr/local/lib -lpng -L/usr/local/grass-6.3.cvs/lib -lgrass_vect -lgrass_dig2 -lgrass_dgl -lgrass_rtree -lgrass_linkm -lgrass_dbmiclient -lgrass_dbmibase -lgrass_I -lgrass_gproj -lgrass_vask -lgrass_gmath -lgrass_gis -lgrass_datetime -lz -L/usr/local/lib -lgdal" 
```

Now, GDAL should be able to work also with GRASS raster layers.

=== GEOS ===

Download the sources:
	http://geos.refractions.net/geos-2.2.3.tar.bz2

Unpack to e.g. ``c:\msys\local\src``

To compile, I had to patch the sources: in file ``source/headers/timeval.h`` line 13.
Change it from:
```
#ifdef _WIN32
```
to:
```
#if defined(_WIN32) && defined(_MSC_VER)
```

Now, in MSYS console, go to the source directory and run:

```
./configure --prefix=/usr/local
make
make install
```


=== SQLITE ===

You can use precompiled DLL, no need to compile from source:

Download this archive:
	http://www.sqlite.org/sqlitedll-3_3_17.zip

and copy sqlite3.dll from it to ``c:\msys\local\lib``

Then download this archive:
	http://www.sqlite.org/sqlite-source-3_3_17.zip

and copy sqlite3.h to ``c:\msys\local\include``


=== GSL ===

Download sources:
	ftp://ftp.gnu.org/gnu/gsl/gsl-1.9.tar.gz

Unpack to ``c:\msys\local\src``

Run from MSYS console in the source directory:

```
./configure
make
make install
```

=== EXPAT ===

Download sources:
	http://dfn.dl.sourceforge.net/sourceforge/expat/expat-2.0.0.tar.gz

Unpack to ``c:\msys\local\src``

Run from MSYS console in the source directory:

```
./configure
make
make install
```

=== POSTGRES ===

We're going to use precompiled binaries. Use the link below for download:
	http://wwwmaster.postgresql.org/download/mirrors-ftp?file=%2Fbinary%2Fv8.2.4%2Fwin32%2Fpostgresql-8.2.4-1-binaries-no-installer.zip

copy contents of pgsql directory from the archive to ``c:\msys\local``


== Cleanup ==

We're done with preparation of MSYS environment. Now you can delete all stuff in ``c:\msys\local\src`` - it takes quite a lot
of space and it's not necessary at all.
