Hi,
I tried to build the latest FlightGear obtained from cvs but it
failed with the following error:
FlightGear/build/FlightGear/libMain.a(renderer.o) reference to
undefined osg::CameraNode::CameraNode()
collect2: ld returned 1 exit status
The cause of this is very simple.
OpenSceneGraph changed a class name from CameraNode to Camera,
so Main/renderer.cxx should have also been changed but it wasn't.
So, I changed it and successfully built fgfs.
Here's the diff for the file.
Hope it helps you guys.
