The error codes below tell me you're missing one library from the linkage. Let me trim the list a bit: > (...) undefined reference to `virtual thunk to > osg::NodeVisitor::~NodeVisitor()' (...) > collect2: ld returned 1 exit status > make[2]: *** [fgfs] Error 1 > make[2]: Leaving directory `/usr/local/src/fg-cvs/source/src/Main' > make[1]: *** [all-recursive] Error 1 > make[1]: Leaving directory `/usr/local/src/fg-cvs/source/src' > make: *** [all-recursive] Error 1 The only thing you seem to be missing is the osg::NodeVisitor The command $ grep "NodeVisitor" /usr/lib/lib*so | sed "s|Binary file /usr/lib/lib|-l|;s|.so matches||" gives a list of all libraries that mention a function "NodeVisitor" on my system there are 15 libraries. You're including six of these libraries already: -losg -losgSim -losgDB -losgUtil -lsgmodel -lsgtgdb -lsgutil The other nine are: -losgFX -losgGA -losgManipulator -losgParticle -losgProducer -losgShadow -losgTerrain -losgText -losgViewer You could try rerunning the failed command with these nine libraries tacked on to see if that fixes your issue.
