yes. I am not sure, if this is also problematic, when building a cross-glibc, then I need also a cross C compiler first, build glibc, and install .h and objects to the sysroot, then I build gcc again, with all languages. > >> With the attached patch, I was finally able to build the cross >> compiler, by declaring abort in the way as it is done already in many >> other places at libgcc. > > Can you just use __builtin_abort ()? Ok with that change. > I will try, but ./config/ia64/unwind-ia64.c includes this header, and it also uses abort () at many places. So I'd expect warnings there. Thanks Bernd.
