When you say assembly... where can I pass elegantly "-no-integrated-as"? Globally in CFLAGS | CXXFLAGS | LDFLAGS? In src/mapi/Makefile.am only? E.g. in shared_glapi_libglapi_la_LDFLAGS? - Sedat - _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
