Maybe you have more than one copy of this file, and are accidentally using an older version than the one in the gcc source tree? I see that you have lots of -I and -isystem options which normally should not be needed. The gcc one is gcc/config/i386/cpuid.h and should get installed into the gcc install tree. In general, you can find some useful info about cross building toolchains in the crosstool-ng project. https://crosstool-ng.github.io/ Note that gmp, mpfr, mpc, and isil can just be dropped into the gcc source tree, alongside the other libraries like libgcc and libstdc++, and the gcc Makefile will build them for you as part of the gcc build. That should also work for zlib but I haven't tried that in a while. For libiconv, it is simpler to just use --disable-nls, but it looks like the toplevel makefile has support for that too, so adding that into the gcc source tree looks like it would work too. Jim
