Building FlightGear - Debian
Article is under construction though only minor details are missing, it should work in most cases.

HowTo build FlightGear 2.6.0 or bleeding edge development version, hereinafter simply called GIT, on GNU/Linux Debian Stable 6.x (Squeeze) and Testing (Wheezy).
The meaning of this article is to be a short, checklist like, overview of the specific steps to compile FlightGear and components on Debian. For more detailed information please refer to the main article Building FlightGear on Linux.
If you don't want to get your hands dirty, have a look at Scripted Compilation on Linux Debian/Ubuntu.
Requirements and Preparations
You need an OpenGL capable graphics card including a proper installed driver supporting direct rendering.
Also a bunch of packages (as well as some of their dependencies) are required to compile FlightGear:
- Tools
su -c "apt-get install automake bzip2 cmake g++ gcc git make subversion tar"
- cmake: At least version 2.6.0-5 required!
- Libs
su -c "apt-get install libc6-dev libgl1-mesa-dev freeglut3-dev libalut-dev \ libboost1.42-dev libsvn-dev libxml2-dev libcurl4-openssl-dev libgtkglext1-dev \ libopenal-dev libpng12-dev librsvg2-dev libtiff4-dev libfltk1.1-dev"
- If you prefer you might replace libcurl4-openssl-dev by libcurl4-gnutls-dev.
- During installation packages simgear-dev and openscenegraph-dev must not be installed. They can safely be re-installed after compilation.
Build and install
Because we are going to install versions different to the ones in the repositories, it is recommended to install FlightGear in a place independent of the base system, such as /usr/local/FG-2.6.0
or $HOME/FG-2.6.0
. This way also has the advantage of easily managing several FlightGear versions, even with different versions of OpenSceneGraph and/or plib. I suggest to make this directory writeable by the user so there is no need to become root for the make install
commands. We'll use $prefix
as a placeholder for this directory.
Another placeholder will be $srcdir
, it stands for the absolute path to the directory which is supposed to keep the folders of the various source codes. So, in the following instructions, you have to replace these with the local paths or even export
them during the process:
export prefix=$HOME/FG-2.6.0; mkdir $prefix export srcdir=$HOME/src; mkdir $srcdir
Have in mind that the data is a relatively large download (GIT about 4.4 GB and 2.6.0 540 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 section.
libopenal
Lenny only! 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
2.6.0 and GIT: Latest SVN is 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
GIT users, especially developers, may want to use the latest release or even bleeding edge code here instead.
2.6.0 and GIT:
cd $srcdir svn co http://www.openscenegraph.org/svn/osg/OpenSceneGraph/tags/OpenSceneGraph-3.0.1 OpenSceneGraph mkdir osg-build && cd osg-build cmake -D CMAKE_BUILD_TYPE="Release" -DLIB_POSTFIX="" \ -D CMAKE_INSTALL_PREFIX:PATH="$prefix" $srcdir/OpenSceneGraph make install
SimGear
2.6.0 and GIT:
cd $srcdir git clone git://mapserver.flightgear.org/simgear
2.6.0 only:
cd simgear git checkout -b 2.6.0 origin/release/2.6.0
2.6.0 and GIT:
mkdir $srcdir/sg-build && cd $srcdir/sg-build cmake -D CMAKE_INSTALL_PREFIX:PATH="$prefix" $srcdir/simgear make install
FlightGear source
2.6.0 and GIT:
cd $srcdir git clone git://mapserver.flightgear.org/flightgear
2.6.0 only:
cd flightgear git checkout -b 2.6.0 origin/release/2.6.0
2.6.0 and GIT:
mkdir $srcdir/fg-build && cd $srcdir/fg-build cmake -D CMAKE_INSTALL_PREFIX:PATH="$prefix" $srcdir/flightgear make install
FlightGear data
2.6.0 only: Please have a look at the mirror list for a server close to your location.
cd $prefix wget http://mirrors.ibiblio.org/pub/mirrors/flightgear/ftp/Shared/FlightGear-data-2.6.0.tar.bz2 tar xjf FlightGear-data-2.6.0.tar.bz2
GIT only:
For slow/unstable internet connections it is recommended to download the fgdata.bundle instead of cloning the data.
cd $prefix git clone git://mapserver.flightgear.org/fgdata data
Trial run and finishing process
When all the builds are done and the data download has finished it is time for a test run:
export LD_LIBRARY_PATH=$prefix/lib/:$LD_LIBRARY_PATH $prefix/bin/fgfs --fg-root=$prefix/data
Have in mind that fgfs
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. You might want to add this line to your $HOME/.bashrc
to have this as a persistent setting.
To avoid the need to give the path to the fgfs
command in the second line, you might consider to create a symlink to place that is listed in $PATH:
ln -s $HOME/FG-2.6.0/bin/fgfs $HOME/bin/fgfs
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 compiling fgrun or check FGo!.
Optional Software
Many of the below instructions are most likely not up to date. Please feel free to revise them.
Feel free to add the commands to install other FlightGear related projects.
Atlas
cd $srcdir cvs -d:pserver:anonymous@atlas.cvs.sourceforge.net:/cvsroot/atlas login #CVS passwd: [Enter] cvs -z3 -d:pserver:anonymous@atlas.cvs.sourceforge.net:/cvsroot/atlas co Atlas cd Atlas ./autogen.sh ./configure --prefix=$prefix make install
fgcom
For fgcom unfortunately there is one more dependency which cannot be solved with packages on Lenny, see 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
TaxiDraw
To compile TaxiDraw we need to install some more packages:
- either libcurl4-gnutls-dev or libcurl4-openssl-dev for curl.h
- wx2.8-headers (at least, maybe even more than just that one. Please report!
su -c "aptitude install [libcurl4-gnutls-dev|libcurl4-openssl-dev]" cd $srcdir git clone git://mapserver.flightgear.org/taxidraw cd taxidraw ./autogen.sh ./configure --prefix=$prefix make install
TerraGear
To resolve some of the dependencies of TerraGear the GIT sections of steps plib, OpenSceneGraph and SimGear have to be done first. Additionally some packages and their dependencies have to be installed:
- libgdal1-dev, gdal-bin
- libproj-dev, libogdi3.2-dev (probably even more, please report!)
Wheezy: As of June 2nd there is a bug (#617240) in package libmysqlclient16 which causes compilation to fail. If it is not fixed by the time you're building TerraGear, upgrade to the version from Sid.
cd $srcdir git clone git://mapserver.flightgear.org/terragear-cs
Two of the dependencies have to be installed manually (See README.gpc and 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 (See README for details.):
cd $srcdir/terragear-cs ./autogen.sh ./configure --prefix=$prefix sed s/-O2// -i src/Lib/TriangleJRS/Makefile make install
