Building FlightGear - Debian
HowTo build on Debian
HowTo build FlightGear 2.0.0 or CVS on GNU/Linux Debian Stable 5.x (Lenny).
This HowTo may also work with Testing/Unstable except that some things are easier because of more up to date packages. So, before fetching something check the version of the available -dev package for it.
It even *should* work with Etch, but I am not certain about some dependencies. Reports are welcome.
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, automake1.9
- mawk (or gawk)
- cmake (min. version 2.6.0-5, for Etch available on backports.org!)
- cvs, subversion
- freeglut3-dev, libgl1-mesa-dev, libxrandr-dev
- libxi-dev, libxmu-dev, libxext-dev
- libopenal-dev (see libopenal), libalut-dev
- libjpeg62-dev, libtiff4-dev, libpng12-dev
- libboost1.37-dev (Not available for Lenny atm, see Boost Library below.)
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 repositries it is recommended to install FG-2.0.0 and/or CVS in a place independet to the base system such as /usr/local/FG-2.0.0, /opt/FG-2.0.0 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 contains the folders of the various source codes. So in the following instructions one have to replace it by the local path.
Subsequent the instructions to fetch the sources and the data needed by FG and the commands to build/install each source.
Have in mind that the data is relatively huge (CVS about 2 GB and 2.0.0 xxx MB) so, to save some time, it is a good idea to fetch it while building the sources.
libopenal
The libopenal-dev package in Lenny/Etch is too old for fgcom. For FG it does work but not all features (like Doppler) are avaiable, so installing an up to date version is recommended anyway. Get the latest source from http://connect.creativelabs.com/openal/Downloads/Forms/AllItems.aspx (file openal-soft-[version]) and extract it into $srcdir
.
cd $srcdir/openal-soft-[version]/build cmake -D CMAKE_INSTALL_PREFIX:PATH="$prefix" .. make install
plib
Version 1.8.5 is needed, packages are available for Testing/Unstable, plib1.8.5-dev. Lenny/Etch users have to compile and install it:
cd $srcdir wget http://plib.sourceforge.net/dist/plib-1.8.5.tar.gz tar xzf plib-1.8.5.tar.gz cd plib-1.8.5 ./configure --prefix=$prefix make install
Boost Library
Version 1.37 is needed. At least for Lenny/Etch this means getting the sources because this is not available atm on backports.org. Testing/Unstable users may have more luck and a package is available, libboost-1.37-dev or newer.
To build SimGear, FlightGear, fgrun and fgcom some boostlib header files are required, no need to compile and install it. If you have installed a libboost1.37-dev (or highter) package on your system you don't have to bother at all with it. If not, you have to tell each ./configure where the header files are. To do so, add the option CPPFLAGS=-I$prefix/include
to the SimGear, FlightGear and fgrun ./configure
commands. We copy the header files to $prefix/include because fgcom will need them there.
Get a tar ball from http://sourceforge.net/projects/boost/files/boost/, extract it into $srcdir
then:
cp -R $srcdir/boost-[version]/boost $prefix/include
OpenSceneGraph
For FlightGear 2.0.0 one may use the latest developer release from http://www.openscenegraph.org/projects/osg/wiki/Downloads/DeveloperReleases (extract into $srcdir
).
Mostly this is ok for FlightGear CVS as well as it is stable. However, sometimes the release is not fresh enough and one have to get the latest developments via SVN:
cd $srcdir svn co http://www.openscenegraph.org/svn/osg/OpenSceneGraph/trunk OpenSceneGraph
cmake demands a build directory separate to its source directory. So mkdir
one and cd
into it.
cmake -D CMAKE_BUILD_TYPE="Release" -D CMAKE_CXX_FLAGS="-O3" -D CMAKE_C_FLAGS="-O3" \ -D CMAKE_INSTALL_PREFIX:PATH="$prefix" $srcdir/OpenSceneGraph[-version] make install
SimGear
2.0.0:
cd $srcdir wget ftp://ftp.simgear.org/pub/simgear/Source/SimGear-....tar.gz tar ... cd ...
CVS:
cd $srcdir mkdir simgear cd simgear cvs -d :pserver:cvsguest@cvs.simgear.org:/var/cvs/SimGear-0.3 login #CVS passwd: guest cvs -d :pserver:cvsguest@cvs.simgear.org:/var/cvs/SimGear-0.3 co source cd source
2.0.0 and CVS:
./autogen.sh ./configure --prefix=$prefix [CPPFLAGS=-I$prefix/include] make install
FlightGear source
2.0.0:
cd $srcdir wget http://www.very-clever.com/download/flightgear/Source/ tar xjf ... cd ...
CVS:
cd $srcdir mkdir flightgear cd flightgear cvs -d :pserver:cvsguest@cvs.flightgear.org:/var/cvs/FlightGear-0.9 login #CVS passwd: guest cvs -d :pserver:cvsguest@cvs.flightgear.org:/var/cvs/FlightGear-0.9 co source cd source
2.0.0 and CVS:
./autogen.sh ./configure --prefix=$prefix [--with-openal=$prefix] [CPPFLAGS=-I$prefix/include/] make install
FlightGear data
2.0.0:
cd $prefix/share wget http://www.very-clever.com/download/flightgear/Shared/FlightGear-data-... tar xjf ...
CVS:
cd $prefix/share cvs -d :pserver:cvsguest@cvs.flightgear.org:/var/cvs/FlightGear-0.9 co data
Trial run
When all the builds are done and the data download has finished it is time for a test run:
export LD_LIBRARY_PATH=$prefix/lib/:$LD_LIBRARY_PATH $prefix/bin/fgfs --fg-root=$prefix/share/data
For the furure, 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.
Optional Software
fgrun
To build fgrun one more package is required:
- libfltk1.1-dev
cd $srcdir svn co http://fgrun.svn.sourceforge.net/svnroot/fgrun/trunk fgrun cd fgrun
./autogen.sh ./configure --prefix=$prefix [CPPFLAGS=-I$prefix/include/] make install
fgcom
For fgcom unfortunately there is one more dependency which cannot be solved with packages on Lenny/Etch, 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
Keeping the CVS version up to date
...to be continued. ;-)
