Agreed.

Most likely this is an issue with the cross setup. host-x-host crossesare a pain, but can work.

I'd set this up as a single source build tree for gcc, binutils & gdbwhich used a sysroot to get all the aix headers & libraries.

Judicious use of "-v" can help spot calling the wrong linker, linkingthe wrong libraries, wrong header file include paths, etc.
