Just comment or remove the else block and all compiles perfect. GLint64 is
already defined in headers provided by Mesa3d for your platform as "typedef
khronos_int64_t GLint64;" For Windows maybe, have nothing to say here because i
dont use it, but for Linux why should we redefine something here explicitly?
