Building FlightGear - Debian
HowTo build FlightGear 2.12 or bleeding edge development version, hereinafter simply called GIT, on GNU/Linux Debian Oldstable/Squeeze. Users of Stable/Wheezy, Testing or Unstable at least have to change package names (version numbering) accordingly.
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
A bunch of packages (as well as some of their dependencies) are required to compile FlightGear:
su -c "apt-get install automake cmake g++ gcc git make sed subversion"
- Additionally install "fluid" if you intend to use fgadmin.
Command for Squeeze, users of other releases are advised to check package versions:
su -c "apt-get install \ freeglut3-dev libboost-dev libcurl4-openssl-dev libgtkglext1-dev \ libjpeg62-dev libopenal-dev librsvg2-dev libsvn-dev \ libxml2-dev libxrandr-dev"
- If you prefer you might replace "libcurl4-openssl-dev" by "libcurl4-gnutls-dev".
- If "libjpeg62-dev" breaks package dependencies, just install one of the other versions' -dev.
- Add "libudev-dev" if you need FG's feature
- During installation development packages of libraries which are going to be compiled must not be installed. They can safely be re-installed after compilation. Namely here these might be "libplib-dev", "libfltk1.1-dev", "libopenscenegraph-dev" and "simgear-dev".
Build and install
Because we are going to install versions different to the ones in the Debian repositories, it is recommended to install FlightGear in a place independent of the base system, such as
$HOME/FG-2.12. This way also has the advantage of easily managing several FlightGear versions, even with different versions of OpenSceneGraph and/or plib, simply by altering the installation prefix. I suggest to make this directory writeable by the user so there is no need to become root for the
make -j2 install commands. We'll use
$FG_INSTALL_DIR as a placeholder for this directory.
Another placeholder will be
$FG_SRC_DIR, it stands for the absolute path to the directory which is supposed to keep the folders of the various source codes. So, in the instructions below, you have to replace these with the local paths or even
export them (in every terminal you're using them) for the process:
export FG_INSTALL_DIR=$HOME/FG-2.12 && mkdir $FG_INSTALL_DIR export FG_SRC_DIR=$HOME/src && mkdir $FG_SRC_DIR
Have in mind that the data is a relatively large download (GIT more than 7 GB and growing / 2.12 960 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.
To have a build with debugging symbols add
-D CMAKE_BUILD_TYPE="RelWithDebInfo" to SimGear's and FlightGear's cmake options.
FLTK only is required for fgadmin, which is content with libfltk-1.1, and fgrun, which minimum is libfltk-1.3.
Wheezy: Just install package "libfltk1.3-dev" if you're planning to use either of them.
Squeeze: For fgadmin just install package "libfltk1.1-dev". To compile fgrun, too, build and install FLTK-1.3 instead:
cd $FG_SRC_DIR wget http://ftp.easysw.com/pub/fltk/1.3.2/fltk-1.3.2-source.tar.gz tar xzf fltk-1.3.2-source.tar.gz cd fltk-1.3.2 ./configure --enable-shared --prefix=$FG_INSTALL_DIR make -j2 install
2.12 and GIT: Latest SVN is required.
cd $FG_SRC_DIR svn co https://svn.code.sf.net/p/plib/code/trunk plib.svn cd plib sed s/PLIB_TINY_VERSION\ \ 5/PLIB_TINY_VERSION\ \ 6/ -i src/util/ul.h ./autogen.sh ./configure --prefix=$FG_INSTALL_DIR make -j2 install
On Wheezy skip that step and install package "libopenscenegraph-dev" instead.
Last version known to work for 2.12 is OpenSceneGraph 3.1.4.
2.12 and GIT:
cd $FG_SRC_DIR svn co http://svn.openscenegraph.org/svn/osg/OpenSceneGraph/tags/OpenSceneGraph-3.1.4 OpenSceneGraph-3.1.4.svn mkdir build-osg; cd build-osg cmake -D CMAKE_BUILD_TYPE="Release" -DLIB_POSTFIX="" \ -D CMAKE_INSTALL_PREFIX:PATH="$FG_INSTALL_DIR" $FG_SRC_DIR/OpenSceneGraph-3.1.4.svn make -j2 install
2.12 and GIT:
cd $FG_SRC_DIR git clone git://mapserver.flightgear.org/simgear simgear.git
cd simgear.git git checkout -b 2.12 origin/release/2.12.0
2.12 and GIT:
mkdir $FG_SRC_DIR/build-sg; cd $FG_SRC_DIR/build-sg cmake -D CMAKE_INSTALL_PREFIX:PATH="$FG_INSTALL_DIR" $FG_SRC_DIR/simgear.git make -j2 install
2.12 and GIT:
cd $FG_SRC_DIR git clone git://mapserver.flightgear.org/flightgear flightgear.git
cd flightgear.git git checkout -b 2.12 origin/release/2.12.0
2.12 and GIT:
mkdir $FG_SRC_DIR/build-fg; cd $FG_SRC_DIR/build-fg cmake -D CMAKE_INSTALL_PREFIX:PATH="$FG_INSTALL_DIR" $FG_SRC_DIR/flightgear.git make -j2 install
2.12 only: Please have a look at the mirror list for a server close to your location.
cd $FG_INSTALL_DIR wget http://mirrors.ibiblio.org/pub/mirrors/flightgear/ftp/Shared/FlightGear-data-2.12.0.tar.bz2 tar xjf FlightGear-data-2.12.0.tar.bz2
For slow/unstable internet connections it is recommended to download the fgdata.bundle instead of cloning the data.
cd $FG_INSTALL_DIR git clone git://mapserver.flightgear.org/fgdata data
Trial run and finishing process
When all the builds are done and the data download has finished it is time for a test run:
export LD_LIBRARY_PATH=$FG_INSTALL_DIR/lib/:$LD_LIBRARY_PATH $FG_INSTALL_DIR/bin/fgfs --fg-root=$FG_INSTALL_DIR/data
fgfsbinary needs to find our self compiled libraries at runtime 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/.bashrcto have this as a persistent setting (may cause problems, if one has installed more than one version of FlightGear!).
- Have in mind, the
$FG_SRC_DIRvariables are available for this session only. For future use of these lines, replace them by the real paths.
To avoid the need to give the path to the
fgfs command each time, you might consider to create a symlink at a place that is listed in $PATH:
ln -s $FG_INSTALL_DIR/bin/fgfs $HOME/bin/fgfs
Feel free to add the commands to install other FlightGear related projects.
One more Package has to be installed: "libglew1.5-dev"
cd $FG_SRC_DIR git clone http://mapserver.flightgear.org/git/atlas cd atlas ./autogen.sh ./configure --prefix=$FG_INSTALL_DIR --with-fgbase=$FG_INSTALL_DIR/data make -j2 install cp -R $FG_SRC_DIR/atlas/src/data/* $FG_INSTALL_DIR/data/Atlas
For fgcom install package "libasound2-dev".
cd $FG_SRC_DIR svn co https://appfgcom.svn.sourceforge.net/svnroot/fgcom/trunk fgcom cd fgcom/src make -j2 install_BIN=$FG_INSTALL_DIR/bin INSTALL_DIR=$FG_INSTALL_DIR/fgcom \ PLIB_PREFIX=$FG_INSTALL_DIR [OPENAL_PREFIX=$FG_INSTALL_DIR] install
Create an .alsoftrc file as shown in FGCOM Testing.
cd $FG_SRC_DIR git clone git://gitorious.org/fg/fgrun.git
cd fgrun git checkout -b 1.7.0 origin/release/1.7.0
2.10.0 and GIT:
mkdir $FG_SRC_DIR/build-fgrun; cd $FG_SRC_DIR/build-fgrun cmake -D CMAKE_INSTALL_PREFIX:PATH="$FG_INSTALL_DIR" $FG_SRC_DIR/fgrun make -j2 install
2.10.0 and GIT:
export LD_LIBRARY_PATH=$FG_INSTALL_DIR/lib/:$LD_LIBRARY_PATH $FG_INSTALL_DIR/bin/fgrun
- 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 $FG_SRC_DIR git clone git://mapserver.flightgear.org/taxidraw cd taxidraw ./autogen.sh ./configure --prefix=$FG_INSTALL_DIR make -j2 install
link If you are familiar with "download_and_compile.sh" script from Brisa you can donwload this script: http://clemaez.fr/flightgear/terragear_download_and_compile.sh This script is similar to Brisa's one (only usable for Debian/Mint/Ubuntu). This script installs TerraGear (latest version) and terragear-gui.
- How to use it?
sh terragear_download_and_compile.sh -j 2 ALL
- Need some help?
Look at forum topics : http://www.flightgear.org/forums/viewtopic.php?f=20&t=14849
After success installation you can exectute this command line in the terragear/bin directory in order to display every --help for each binary files:
cd terragear/bin && for i in `ls`; do echo ""; echo "################# "$i" ##############"; ./$i --help; done
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:
su -c "apt-get install \ libgdal-dev libtiff4-dev libboost-signals-dev libboost-system-dev libboost-thread-dev"
Squeeze users have to compile the CGAL dependency. On Wheezy just install package "libcgal-dev" instead.
cd $FG_SRC_DIR wget https://gforge.inria.fr/frs/download.php/31174/CGAL-4.0.2.tar.bz2 tar xjf CGAL-4.0.2.tar.bz2 mkdir $FG_SRC_DIR/build-cgal; cd $FG_SRC_DIR/build-cgal cmake -D CMAKE_INSTALL_PREFIX:PATH="$FG_INSTALL_DIR" $FG_SRC_DIR/CGAL-4.0.2 make -j2 install
cd $FG_SRC_DIR git clone git://git.gitorious.org/fg/terragear.git mkdir $FG_SRC_DIR/build-tg; cd $FG_SRC_DIR/build-tg cmake -D CMAKE_INSTALL_PREFIX:PATH="$FG_INSTALL_DIR" $FG_SRC_DIR/terragear make -j2 install
