Hi John, Man that's frustrating. This really does look a buggy compiler.... The friend even allowed me make the nested base class private on gcc 4.3.2, for gcc 3.2 to ignore the friend, and not obey the usual rules of subclasses having access to protected members is doubly bad.
I've been reviewing docs on ABI compatibility and moving this nested class to the public scope would indeed break binary compatibility, so isn't something we can entertain for OSG-2.8.1. Unless someone can spot another way of tricking gcc 3.2 to not tripping over this code we'll just to accept 2.8.1 won't compile out of the box under RHEL 3.2, and pointer users at what mods they can make locally. For the 2.9.x series we could possible look at re-organizing the classes in a way that breaks the ABI, since the ABI is already incompatible with 2.8.0. Robert.
