Binutils works for AIX 4.3.3 and possibly AIX 5.1. Unfortunately, it has not been updated and creates incorrect object files when used on later releases of AIX. My advice is tell IBM sales people that this feature and functionality is necessary. IBM responds to customers and ISVs. If they tell IBM GNU Binutils and cross-compilation is important for business, IBM will take action. > Does it mean that my binaries with static libgcc and libstdc++ (custom > gcc build, so "static" library does not contain .so) work purely by > chance? Or are you writing about newest gcc versions? It depends what C++ features you use and how the libraries are built. Building completely static archive libraries may work. The other approach is build normal (shared) libraries but statically link them. The problem is throwing exceptions across library boundaries because one can end up with separate copies of the EH data structures. Newer versions of GCC should automatically link with libsupc++ for static linking to resolve at least that part of the problem. - David
