--- Comment #5 from Eric Gallager <egallager at gcc dot gnu.org> --- (In reply to Jay from comment #4) > Here is a lame workaround that works, from my Python wrapper: > > if (Host == Target) and (Host != Build): > ExtraConfig += " -with-sysroot=/" > ExtraConfig += " -with-build-sysroot=" + DefaultSysroot To be clear, is that a wrapper around GCC or fixincludes? In either case, can you link us to your Python wrapper?
