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