If all has worked properly the QGIS application should start up and appear
|
||||
on your screen.
|
||||
|
||||
|
||||
== A practical case: Building QGIS and GRASS from source on Ubuntu with ECW and MrSID formats support ==
|
||||
|
||||
The following procedure has been tested on Ubuntu 8.04, 8.10 and 9.04 32bit. If you want
|
||||
to use different versions of the software (gdal, grass, qgis), just make the
|
||||
necessary adjustments to the following code. This guide assumes that you don't have
|
||||
installed any previous version of gdal, grass and qgis.
|
||||
|
||||
=== Step 1: install base packages ===
|
||||
|
||||
First you need to install the necessary packages required to download the source
|
||||
code and compile it. Open the terminal and issue the following command:
|
||||
|
||||
```
|
||||
sudo apt-get install build-essential g++ subversion
|
||||
```
|
||||
|
||||
=== Step 2: compile and install the ecw libraries ===
|
||||
|
||||
Go to the ERDAS web site http://www.erdas.com/ and follow the links
|
||||
"'''products --> ECW JPEG2000 Codec SDK --> downloads'''"
|
||||
then download the "'''Image Compression SDK Source Code 3.3'''" (you'll need to make a registration
|
||||
and accept a license).
|
||||
|
||||
Uncompress the arquive in a proper location (this guide assumes
|
||||
that all the downloaded source code will be placed in the user home)
|
||||
and the enter the newly created folder
|
||||
|
||||
```
|
||||
cd /libecwj2-3.3
|
||||
```
|
||||
|
||||
Compile the code with the standard commands
|
||||
|
||||
```
|
||||
./configure
|
||||
```
|
||||
|
||||
then
|
||||
|
||||
```
|
||||
make
|
||||
```
|
||||
|
||||
then
|
||||
|
||||
```
|
||||
sudo make install
|
||||
```
|
||||
|
||||
leave the folder
|
||||
|
||||
```
|
||||
cd ..
|
||||
```
|
||||
|
||||
=== Step 3: download the MrSID binaries ===
|
||||
|
||||
Go to the LIZARDTECH web site http://www.lizardtech.com/ and follow the links
|
||||
"'''download --> Developer SDKs'''",
|
||||
then download the "'''GeoExpress SDK for Linux (x86) - gcc 4.1 32-bit'''"
|
||||
(you'll need to make a registration and accept a license).
|
||||
|
||||
Uncompress the downloaded file. The resulting directory name should be similar to "Geo_DSDK-7.0.0.2167"
|
||||
|
||||
=== Step 4: compile and install the gdal libraries ===
|
||||
|
||||
Download the latest gdal source code
|
||||
|
||||
```
|
||||
svn checkout https://svn.osgeo.org/gdal/trunk/gdal gdal
|
||||
```
|
||||
|
||||
then copy a few files from the MrSID binaries folder to the folder with the gdal source code
|
||||
('''replace "USERNAME" with your actual account username''')
|
||||
|
||||
```
|
||||
cp /home/USERNAME/Geo_DSDK-7.0.0.2167/include/*.* /home/USERNAME/gdal/frmts/mrsid/
|
||||
```
|
||||
|
||||
enter the gdal source code folder
|
||||
|
||||
```
|
||||
cd /gdal
|
||||
```
|
||||
|
||||
and run configure with a few specific parameters
|
||||
|
||||
```
|
||||
./configure --without-grass --with-mrsid=../Geo_DSDK-7.0.0.2167 --without-jp2mrsid
|
||||
```
|
||||
|
||||
at the end of the configuration process you should read something like
|
||||
|
||||
```
|
||||
...
|
||||
GRASS support: no
|
||||
...
|
||||
...
|
||||
...
|
||||
ECW support: yes
|
||||
MrSID support yes
|
||||
...
|
||||
```
|
||||
|
||||
then compile normally
|
||||
|
||||
```
|
||||
make
|
||||
```
|
||||
|
||||
and
|
||||
|
||||
```
|
||||
sudo make install
|
||||
```
|
||||
|
||||
finish the process by creating the necessary links to the most recent shared libraries
|
||||
|
||||
```
|
||||
sudo ldconfig
|
||||
```
|
||||
|
||||
at this point you may want to check if gdal was compiled correctly with MrSID and ECW
|
||||
support by issuing one (or both) of the following commands
|
||||
|
||||
```
|
||||
gdalinfo --formats | grep 'ECW'
|
||||
```
|
||||
|
||||
```
|
||||
gdalinfo --formats | grep 'SID'
|
||||
```
|
||||
|
||||
leave the folder
|
||||
|
||||
```
|
||||
cd ..
|
||||
```
|
||||
|
||||
=== Step 5: compile and install GRASS ===
|
||||
|
||||
Before downloading and compile GRASS source code you need to install a few
|
||||
other libraries and programs. We can do this trough apt
|
||||
|
||||
```
|
||||
sudo apt-get install flex bison libreadline5-dev libncurses5-dev lesstif2-dev debhelper dpatch libtiff4-dev \
|
||||
tcl8.4-dev tk8.4-dev fftw-dev xlibmesa-gl-dev libfreetype6-dev autoconf2.13 autotools-dev \
|
||||
libgdal1-dev proj libjpeg62-dev libpng12-dev libpq-dev unixodbc-dev doxygen fakeroot cmake \
|
||||
python-dev python-qt4-common python-qt4-dev python-sip4 python2.5-dev sip4 libglew1.5-dev libxmu6 \
|
||||
libqt4-dev libgsl0-dev python-qt4 swig python-wxversion python-wxgtk2.8 libwxgtk2.8-0 libwxbase2.8-0 tcl8.4-dev \
|
||||
tk8.4-dev tk8.4 libfftw3-dev libfftw3-3
|
||||
```
|
||||
|
||||
At this point we can get the GRASS source code: you may want to download it
|
||||
trough svn or maybe you want just to download the latest available source code arquive.
|
||||
For example the GRASS 6.4rc4 is available at http://grass.itc.it/grass64/source/grass-6.4.0RC4.tar.gz
|
||||
|
||||
Uncompress the arquive, enter the newly created folder and run configure with a few specific parameters
|
||||
|
||||
```
|
||||
./configure --with-tcltk-includes=/usr/include/tcl8.4 --with-proj-share=/usr/share/proj --with-gdal=/usr/local/bin/gdal-config --with-python=/usr/bin/python2.5-config
|
||||
```
|
||||
|
||||
then as usual (it will take a while)
|
||||
|
||||
```
|
||||
make
|
||||
```
|
||||
|
||||
and
|
||||
|
||||
```
|
||||
sudo make install
|
||||
```
|
||||
|
||||
leave the folder
|
||||
|
||||
```
|
||||
cd ..
|
||||
```
|
||||
|
||||
you have now compiled and installed GRASS (also with the new wxpyhton interface) so you
|
||||
may want to give it a try
|
||||
|
||||
```
|
||||
grass64 -wxpython
|
||||
```
|
||||
|
||||
=== Step 6: compile and install the GDAL-GRASS libraries ===
|
||||
|
||||
Create a plain text file named "grass.conf" inside the folder "/etc/ld.so.conf.d"
|
||||
|
||||
```
|
||||
sudo gedit /etc/ld.so.conf.d/grass.conf
|
||||
```
|
||||
|
||||
and add the following line
|
||||
|
||||
```
|
||||
/usr/local/grass-6.4.0RC4/lib/
|
||||
```
|
||||
|
||||
save and exit.
|
||||
|
||||
Download the latest version of the gdal-grass library (gdal-grass-1.4.3.tar.gz) from
|
||||
http://download.osgeo.org/gdal/
|
||||
|
||||
uncompress the arquive and enter the newly created folder
|
||||
|
||||
```
|
||||
cd /gdal-grass-1.4.3
|
||||
```
|
||||
|
||||
run configure
|
||||
|
||||
```
|
||||
./configure --with-grass=/usr/local/grass-6.4.0RC4
|
||||
```
|
||||
|
||||
then as usual
|
||||
|
||||
```
|
||||
make
|
||||
```
|
||||
|
||||
and
|
||||
|
||||
```
|
||||
sudo make install
|
||||
```
|
||||
|
||||
and finish the process by creating the necessary links to the most recent shared libraries
|
||||
|
||||
```
|
||||
sudo ldconfig
|
||||
```
|
||||
|
||||
leave the folder
|
||||
|
||||
```
|
||||
cd ..
|
||||
```
|
||||
|
||||
=== Step 6: compile and install QGIS ===
|
||||
|
||||
As for GRASS you can obtain the QGIS source code from different sources,
|
||||
for instance from svn or just by downloading one of the source code arquives available
|
||||
at http://www.qgis.org/download/sources.html
|
||||
|
||||
For example download the QGIS 1.1.0 source code here http://download.osgeo.org/qgis/src/qgis_1.1.0.tar.gz
|
||||
|
||||
uncompress the arquive and enter the newly created folder
|
||||
|
||||
```
|
||||
cd /qgis_1.1.0
|
||||
```
|
||||
|
||||
then run ccmake
|
||||
|
||||
```
|
||||
ccmake .
|
||||
```
|
||||
|
||||
press the "c" key, then when the option list will appear we need to manually
|
||||
configure the "GRASS_PREFIX" parameter. Scroll down until the "GRASS_PREFIX" will appear,
|
||||
press enter and manually set it to
|
||||
|
||||
```
|
||||
/usr/local/grass-6.4.0RC4
|
||||
```
|
||||
|
||||
then press enter again.
|
||||
|
||||
Press the "c" again and the option "Press [g] to generate and exit" will appear.
|
||||
Press the "g" key to generate and exit.
|
||||
|
||||
then as usual (it will take a while)
|
||||
|
||||
```
|
||||
make
|
||||
```
|
||||
|
||||
and
|
||||
|
||||
```
|
||||
sudo make install
|
||||
```
|
||||
|
||||
At the end of the process you should have QGIS and GRASS working with MrSID and ECW
|
||||
raster format support.
|
||||
|
||||
To run QGIS just use this command
|
||||
|
||||
```
|
||||
qgis
|
||||
```
