Cheers, I found the problem. It's due to the FindOpenSceneGraph rules for cmake - it specifies to look in /usr/lib, /usr/include etc. Specifically, making openscenegraph doesn't overwrite the find rules for cmake (in the /usr/share/cmake/Modules location) I'm using the build instructions here: http://wiki.flightgear.org/Building_FlightGear_-_Debian I don't know enough about this to fix or correct the problem, but perhaps the instruction on the wiki page needs an update, I've used the following (there's a GIT copy of the SVN source as well) and it's working fine (it's ok for me, I have nothing else on my system that can be impacted by changing OSG - but what if two versions of OSG need to co-exist?): cd $srcdir git clone git://github.com/openscenegraph/osg.git openscenegraph mkdir osg-build && cd osg-build cmake -D CMAKE_BUILD_TYPE="Release" $srcdir/OpenSceneGraph make sudo make install I think a better fix is either to allow a single definition (OSG_BASE_DIR) to define where _ALL_ the osg components can be found, rather than defining each of the OSG_ components for building simgear (I counted 18 of them and I really can't be arsed to type that much - I just want to specify the base and find all the OSG components relative to that base) Chris ------------------------------------------------------------------------------ RSA(R) Conference 2012 Save $700 by Nov 18 Register now http://p.sf.net/sfu/rsa-sfdev2dev1 _______________________________________________ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel
