Because we are going to install versions different to the ones in the repositories it is recommended to install FG-2.2.0 and/or GIT in a place independent to the base system such as /usr/local/FG-2.2.0, /opt/FG-2.2.0 or in a subdirectory of your $HOME. I suggest to make it writeable by the user that there is no need to become root for the <code>make install</code> commands. I'll use <code>$prefix</code> as a placeholder for this directory. <br />

Another one will be <code>$srcdir</code>, it stands for the absolute path to the directory which is supposed to keep the folders of the various source codes. So, in the following instructions, you have to replace these with the local paths or even <code>export</code> them during the process.

Have in mind that the data is a relatively large download (GIT about 3.5 GB and 2.2.0 300 MB). So, to save some time, it is a good idea to fetch it while building the sources.

=== TerraGear ===
To resolve some of the dependencies of [[TerraGear]] the GIT sections of steps [[#plib|plib]], [[#OpenSceneGraph|OpenSceneGraph]] and [[#SimGear|SimGear]] have to be done first. Additionally some packages and their dependencies have to be installed:
* libgdal1-dev, libproj-dev, libogdi3.2-dev (probably even more, please [http://wiki.flightgear.org/index.php?title=Talk:Building_FlightGear_-_Debian&action=edit&redlink=1 report]!)
<u>Wheezy:</u> As of June 2nd there is a bug ([http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=617240 #617240]) in package libmysqlclient16 which causes compilation to fail. If it is not fixed by the time you're building TerraGear, downgrade to the version from Stable/Squeeze.
Two of the dependencies have to be installed manually (See [http://mapserver.flightgear.org/git/?p=terragear-cs;a=blob;f=README.gpc;h=226e185b1ce1d1578006b48bb426e35848cce93b;hb=HEAD README.gpc] and [http://mapserver.flightgear.org/git/?p=terragear-cs;a=blob;f=README.newmat;h=95570b6b279d3d00bd7664cd4f00d6c4802aed1b;hb=HEAD README.newmat] for details.):
# gpc install
mkdir $srcdir/gpc232 && cd $srcdir/gpc232
wget ftp://ftp.cs.man.ac.uk/pub/toby/gpc/gpc232-release.zip
unzip gpc232-release.zip
sed s/DBL_EPSILON/0.000001/ -i gpc.h
grep -A 18 '# Unix/Linux makefile' $srcdir/terragear-cs/README.gpc > Makefile
sed "s|/usr/local/lib|$prefix/lib|" -i Makefile
sed "s|/usr/local/include|$prefix/include|" -i Makefile
make install
# newmat install
mkdir $srcdir/newmat11 && cd $srcdir/newmat11
wget http://www.robertnz.net/ftp/newmat11.tar.gz
tar xzfv newmat11.tar.gz
make -f nm_gnu.mak
cp libnewmat.a $prefix/lib
mkdir $prefix/include/newmat
cp *.h $prefix/include/newmat
Finally TerraGear itself:
cd $srcdir
git clone git://mapserver.flightgear.org/terragear-cs
cd terragear-cs
./autogen.sh
./configure prefix=$prefix
sed s/-O2// -i src/Lib/TriangleJRS/Makefile
  make install
  make install
