HowTo build FlightGear 2.4.0 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 2.4.0 and GIT. At least until the dependencies of the GIT version change.

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:

  • gcc, g++, make, automake, pkg-config
  • mawk (or gawk)
  • cmake (min. version 2.6.0-5)
  • git, subversion, wget
  • 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 I recommend to install FG-2.4.0 and/or GIT in a place independent of the base system such as /usr/local/FG-2.4.0, /opt/FG-2.4.0 or in a subdirectory of your $HOME. I suggest to make it writeable by the user so 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.

export prefix=[path to install to]
export srcdir=[path to sources]

Have in mind that the data is a relatively large download (GIT about 3.5 GB and 2.4.0 410 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

GIT users, especially developers, may want to use the latest release or even bleeding edge code here. Have in mind that, at the time of the FlightGear 2.4.0 release, there are some issues with newer versions than 2.9.10!

cd $srcdir
svn co http://www.openscenegraph.org/svn/osg/OpenSceneGraph/tags/OpenSceneGraph-2.9.10 OpenSceneGraph
sed 's|SET(LIB_POSTFIX "64" CACHE|SET(LIB_POSTFIX "" CACHE|' -i OpenSceneGraph/CMakeLists.txt
mkdir osg-build && cd osg-build
cmake -D CMAKE_BUILD_TYPE="Release" \
      -D CMAKE_INSTALL_PREFIX:PATH="$prefix" $srcdir/OpenSceneGraph
make install


SimGear

2.4.0 and GIT:

cd $srcdir
git clone git://mapserver.flightgear.org/simgear

2.4.0 only:

cd simgear
git checkout -b 2.4.0 origin/release/2.4.0
./autogen.sh
./configure --prefix=$prefix
make install

GIT only:

mkdir sg-build && cd sg-build
cmake -D CMAKE_INSTALL_PREFIX:PATH="$prefix" $srcdir/simgear
make install


FlightGear source

2.4.0 and GIT:

cd $srcdir
git clone git://mapserver.flightgear.org/flightgear

2.4.0 only:

cd flightgear
git checkout -b 2.4.0 origin/release/2.4.0
./autogen.sh
./configure --prefix=$prefix
make install

GIT only:

mkdir fg-build && fd fg-build
cmake -D CMAKE_INSTALL_PREFIX:PATH="$prefix" $srcdir/flightgear
make install


FlightGear data

2.4.0 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-2.4.0.tar.bz2
tar xjf FlightGear-data-2.4.0.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 data


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/data

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 $srcdir
cvs -d:pserver:anonymous@atlas.cvs.sourceforge.net:/cvsroot/atlas login
#CVS passwd: [Enter]
cvs -z3 -d:pserver:anonymous@atlas.cvs.sourceforge.net:/cvsroot/atlas co Atlas
cd Atlas
./autogen.sh
./configure --prefix=$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
