Compiling
When tracking a fast changing software like FlightGear/Git it is highly advisable to install it in a separate directory. That way one can also easily build and reinstall without being root, which greatly reduces the risk of messing up one's system.
To install in a directory of your choice, add the CMAKE_INSTALL_PREFIX
argument to cmake
. E.g., -DCMAKE_INSTALL_PREFIX==/path/to/your/fgInstallation
. I would recommend installing all of OSG, plib, SimGear and FlightGear with the same prefix.
Getting and compiling SimGear
Step 1:
Clone the SimGear git repository and set it up to track the 'next' branch.
$ git clone git://gitorious.org/fg/simgear.git
or if the git port is firewalled on you network, use the http transport
$ git clone http://gitorious.org/fg/simgear.git
By default after cloning you should have a local next branch that tracks the master next branch. It can be updated it with git pull
.
Step 2:
The source code will be downloaded into a directory called simgear.
Next, go into the directory and make preparations for the compilation:
$ cd simgear
$ cmake .
Note that if you don't want to install simgear globally on the system but in a specific directory, you can do so by adding -DCMAKE_INSTALL_PREFIX==/path/to/your/fgInstallation
to the cmake
command
Step 3:
Compile and install SimGear by doing:
$ make; make install
Note: with gcc 4.2 or later,on some platforms, you can get compiling errors about alc.h like:
'<anonymous>' has incomplete type
take a look at http://bugs.gentoo.org/166723
Getting and compiling FlightGear
Step 1:
Clone the FlightGear git repository and set it up to track the 'next' branch.
$ git clone git://gitorious.org/fg/flightgear.git
By default after cloning you should have a local next branch that tracks the master next branch. It can be updated it with git pull.
Step 2:
Next, go into the folder and make preparations for the compilation:
$ cd flightgear
$ ./autogen.sh
$ ./configure
Note that if you don't want to install simgear globally on the system but in a specific directory, you can do so by adding --prefix=/path/to/your/fgInstallation to the ./configure command. If you didn't install OSG globally or in the same prefix as SimGear and FlightGear, you have to pass the OSG directory to the configure-command like this:
$ ./configure --prefix=/path/to/fgInstallation --with-osg=/path/to/osg/installation --enable-osgviewer
In this case you have to tell your system where to find the OSG libraries before you can run flightgear:
$ export LD_LIBRARY_PATH=/path/to/osgInstallation/lib:$LD_LIBRARY_PATH
Step 3:
Now you can compile and install Flightgear by:
$ make; make install
Step 4:
Clone the data directory:
$ git clone git://gitorious.org/fg/fgdata.git
The data directory is large (almost 2.5GB) so it will take considerable time to download. There mirror of fgdata that might be faster to download from:
$ git clone git://mapserver.flightgear.org/fgdata
The mirror is synchronized with the master so either will do.
And install it in (or as) /usr/local/share/FlightGear
$ mv fgdata /usr/local/share/flightgear
