There is little we can do to help you with so little information. That said, the most likely problem is that the code is doing something like this: class C { void C::fn(); } That is invalid C++ syntax, but older versions of gcc--before gcc 3.4, I think--used to accept it. The "C::" must be omitted. Ian
