HowTo build on Debian

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.

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 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.

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), 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 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 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 make install commands. I'll use $prefix as a placeholder for this directory.
Another one 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.

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 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

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

cd $srcdir
svn co http://www.openscenegraph.org/svn/osg/OpenSceneGraph/tags/OpenSceneGraph-2.9.10 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

2.2.0 and GIT:

cd $srcdir
git clone git://gitorious.org/fg/simgear.git simgear
cd simgear

2.2.0 only:

git checkout -b releases/2.2.0 origin/releases/2.2.0

2.2.0 and GIT:

./autogen.sh
./configure --prefix=$prefix 
make install


FlightGear source

2.2.0 and GIT:

cd $srcdir
git clone git://gitorious.org/fg/flightgear.git flightgear
cd flightgear

2.2.0 only:

git checkout -b releases/2.2.0 origin/releases/2.2.0

2.2.0 and GIT:

./autogen.sh
./configure --prefix=$prefix 
make install


FlightGear data

2.2.0 only: 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

GIT only: For slow/unstable internet connections it is recommended to download the fgdata.bundle instead of cloning the data.
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 compiling fgrun or check FGo!. 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.


Optional Software

Feel free to add the commands to install other FlightGear related projects.

Atlas

cd $srcdir
cvs -d:pserver:anonymous@atlas.cvs.sourceforge.net:/cvsroot/atlas login
#CVS passwd: [Enter]
cvs -z3 -d:pserver:anonymous@atlas.cvs.sourceforge.net:/cvsroot/atlas co Atlas
cd Atlas
sed s/get_gbs_center2/get_gbs_center/ -i src/Subbucket.cxx
./autogen.sh
./configure --prefix=$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 that just that. 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
