#REDIRECT[[Building_FlightGear_-_Devuan]]
HowTo build FlightGear 2.2.0 or bleeding edge development version, hereinafter simply called ''GIT'', on GNU/Linux Debian '''Stable''' 6.x (Squeeze) and '''Testing''' (Wheezy).
+
 
+
Even on Debian '''Oldstable''' 5.x (Lenny) this guide will work for both, 2.2.0 and GIT. At least until one or more dependencies of the GIT version are changing or beeing added.
+
 
+
If you don't want to make your hands dirty, have a look at [[Scripted_Compilation_on_Linux_Debian/Ubuntu]].
+
 
+
 
+
== Requirements and Preparations ==
+
You need an OpenGL capable graphics including a proper installed driver.<BR>
+
 
+
Also a bunch of packages (and some of their dependencies) are required:
+
*gcc, g++, make, automake, pkg-config
+
*mawk (or gawk)
+
*cmake  (min. version 2.6.0-5)
+
*git, subversion, wget
+
*freeglut3-dev, libgl1-mesa-dev, libxrandr-dev
+
*libxi-dev, libxmu-dev, libxext-dev
+
*libopenal-dev (for Lenny see [[#libopenal|libopenal]]), libalut-dev
+
*libjpeg62-dev, libtiff4-dev, libpng12-dev
+
*libboost1.37-dev (min 1.37, 1.40 available for Lenny on backports.debian.org)
+
 
+
During installation package ''simgear-dev'' '''must not''' be installed. It can safely be re-installed after compilation. Same for ''openscenegraph-dev'', if you're using a version differnt to that in the Debian repository.
+
 
+
 
+
== Build and install ==
+
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.
+
 
+
For some basic info on git commands for FlightGear users we have a [[Git#For_dummies|git for dummies]] section.
+
 
+
 
+
=== libopenal ===
+
<u>Lenny only!</u> The libopenal-dev package in Lenny is too old for [[fgcom]]. For FlightGear it does work but not all features (like doppler) are available, so installing an up to date version is recommended anyway.
+
cd $srcdir
+
wget http://kcat.strangesoft.net/openal-releases/openal-soft-1.11.753.tar.bz2
+
tar xjf openal-soft-1.11.753.tar.bz2
+
cd openal-soft-1.11.753/build
+
cmake  -D CMAKE_INSTALL_PREFIX:PATH="$prefix" ..
+
make install
+
 
+
 
+
=== plib ===
+
Latest SVN is [http://www.mail-archive.com/flightgear-devel@lists.sourceforge.net/msg20793.html recommended], yet package plib1.8.5-dev for Squeeze does work as well.
+
cd $srcdir
+
svn co https://plib.svn.sourceforge.net/svnroot/plib/trunk plib
+
cd plib
+
sed s/PLIB_TINY_VERSION\ \ 5/PLIB_TINY_VERSION\ \ 6/ -i src/util/ul.h
+
./autogen.sh
+
./configure --prefix=$prefix
+
make install
+
 
+
 
+
=== OpenSceneGraph ===
+
<u>2.2.0 only:</u>
+
su -c "apt-get install libopenscenegraph-dev"
+
<!-- cd $srcdir
+
svn co -r 12170 http://www.openscenegraph.org/svn/osg/OpenSceneGraph/trunk OpenSceneGraph -->
+
 
+
<u>GIT only:</u>
+
Mostly the latest revision from OpenSceneGraph svn does suit. However, sometimes this does not work and as a fallback one can go backwards through the revisions. Revision must be at least 12170 (February 2011).<BR>
+
cd $srcdir
+
svn co http://www.openscenegraph.org/svn/osg/OpenSceneGraph/trunk OpenSceneGraph
+
ln -s lib $prefix/lib64  # 64bit OS' only, if lib64 does not exist
+
mkdir osg-build && cd osg-build
+
cmake -D CMAKE_BUILD_TYPE="Release" \
+
      -D CMAKE_INSTALL_PREFIX:PATH="$prefix" $srcdir/OpenSceneGraph
+
make install
+
 
+
 
+
=== SimGear ===
+
<u>2.2.0 and GIT:</u>
+
cd $srcdir
+
git clone git://gitorious.org/fg/simgear.git simgear
+
cd simgear
+
 
+
<u>2.2.0 only:</u>
+
git checkout -b releases/2.2.0 origin/releases/2.2.0
+
 
+
<u>2.2.0 and GIT:</u>
+
./autogen.sh
+
./configure --prefix=$prefix <!--CPPFLAGS=-I$prefix/include/-->
+
make install
+
 
+
 
+
=== FlightGear source ===
+
<u>2.2.0 and GIT:</u>
+
cd $srcdir
+
git clone git://gitorious.org/fg/flightgear.git flightgear
+
cd flightgear
+
 
+
<u>2.2.0 only:</u>
+
git checkout -b releases/2.2.0 origin/releases/2.2.0
+
 
+
<u>2.2.0 and GIT:</u>
+
./autogen.sh
+
./configure --prefix=$prefix <!--CPPFLAGS=-I$prefix/include/-->
+
make install
+
 
+
 
+
=== FlightGear data ===
+
<u>2.2.0 only:</u>
+
At the time of writing, 2.2.0 is not yet released, there is no tar archive for the data available. Test pilots for this release are advised to use the ''release/2.2.0'' branch from git. The following URL for wget will be updated, if it is not working, as soon as 2.2.0 is released.
+
cd $prefix
+
wget http://mirrors.ibiblio.org/pub/mirrors/flightgear/ftp/Shared/FlightGear-data-2.2.0.tar.bz2
+
tar xjf FlightGear-data-2.2.0.tar.bz2
+
 
+
<u>GIT only:</u>
+
For slow/unstable internet connections it is recommended to download the [[Git#fgdata.bundle|fgdata.bundle]] instead of cloning the data.<BR>
+
FlightGear's primary git server on gitorious is known to have trouble cloning the data, the mapserver's mirror usually has no problems:
+
cd $prefix
+
git clone git://mapserver.flightgear.org/fgdata
+
 
+
 
+
== Trial run ==
+
When all the builds are done and the data download has finished it is time for a test run:
+
export LD_LIBRARY_PATH=$prefix/lib/:$LD_LIBRARY_PATH
+
$prefix/bin/fgfs --fg-root=$prefix/fgdata
+
 
+
For the future, if you want to start FlightGear from command line have a look at [[fgfsrc]], if you prefer a graphical user interface continue with [[#fgrun|compiling fgrun]] or check [[FGo!]]. Have in mind that <code>fgfs</code> need to find our self compiled libraries and therefore we have to tell the linker (ld) where to find them. That is what the first line here does.
+
 
+
 
+
== Optional Software ==
+
Feel free to add the commands to install other FlightGear related projects.
+
 
+
=== fgcom ===
+
For [[fgcom]] unfortunately there is one more dependency which cannot be solved with packages on <u>Lenny</u>, see [[#libopenal|libopenal]].
+
cd $srcdir
+
svn co https://appfgcom.svn.sourceforge.net/svnroot/fgcom/trunk fgcom
+
cd fgcom/src
+
make INSTALL_BIN=$prefix/bin INSTALL_DIR=$prefix/fgcom \
+
    PLIB_PREFIX=$prefix OPENAL_PREFIX=$prefix install
+
 
+
 
+
=== fgrun ===
+
To build [[fgrun]] one more package is required:
+
*libfltk1.1-dev
+
cd $srcdir
+
svn co http://fgrun.svn.sourceforge.net/svnroot/fgrun/trunk fgrun
+
cd fgrun/fgrun/
+
./autogen.sh
+
./configure --prefix=$prefix
+
make install
+
