Since we compile the libraries with the Sun C++ compiler, I doubt LibC++ will work correctly with GCC. Rob Z.

Considering how Sun makes you buy their C++ compiler seperately, would Informix release a G++ version? If not, is there any chance of release the source to just the C++ Classes so developers can compile it themselves?
