The best OSG version to be used with FG GIT changes over time. Generally the latest official stable OSG release and /or developer release is recommended.At the moment (February 2011) , it' s recommended to use ''' OSG 2. 9. 9''' with FG GIT.
svn checkout http://www.openscenegraph.org/svn/osg/OpenSceneGraph/tags/OpenSceneGraph-2.9.9 OpenSceneGraph If you're interested in OSG-related development, you can also try the lastest OSG trunk. However, sometimes this does not work since the OSG trunk changes (daily/hourly...) and it may take a while until the FlightGear sources have adapted. At the moment (February 2011) the latest OSG SVN trunk does ''not'' compile with FlightGear. The highest reported working revision of OSG SVN is '''rev 12072''', so you could cd $srcdir svn co -r 12072 http://www.openscenegraph.org/svn/osg/OpenSceneGraph/trunk OpenSceneGraph
<u>2.2.0 and GIT:</u>
cmake -D CMAKE_BUILD_TYPE="Release" -D CMAKE_INSTALL_PREFIX:PATH="$prefix" $srcdir/OpenSceneGraph
