21 February 2001 - CLO As of version 0.7.2, FlightGear now requires the SimGear supporting libraries to be installed before configuring and building FlightGear. You must also have SimGear installed if you build the TerraGear scenery creating tools (TerraGear is not required to run the simulator). You can get a copy of SimGear from the simgear web page: http://www.simgear.org SimGear build notes: You should be able to just run the standard "./configure; make; make install" to configure, build, and install SimGear. By default, SimGear is installed in /usr/local/lib/libsg*.a and /usr/local/include/simgear/. You may specify an alternate prefix for building and installing SimGear. If you do this, you may have to point the FlightGear configure script to the correct location of SimGear. For instance, if you installed SimGear in /usr/site/include and /usr/site/lib, you could configure FlightGear with "./configure --with-simgear=/usr/site"
