== 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.

At this point we can get the GRASS source code: you may want to download it
through 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

The additional gcc option -fexceptions is necessary to enable exceptions support in GRASS libraries. It is currently the only way to avoid QGIS crashes if a fatal error happens in GRASS library. See also http://trac.osgeo.org/grass/ticket/869

=== 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
As for GRASS you can obtain the QGIS source code from different sources as described
in section 2 above. Once you have the sources, create a build directory in them:

```
cd /qgis_1.1.0
cd Quantum-GIS
mkdir build
cd build
```

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
ccmake ..
```

then press enter again.

Press the "c" key to do an initial configure.
Press the "c" again and the option "Press [g] to generate and exit" will appear.
Press the "g" key to generate and exit.
