Please open a bugreport if you're still having issues building the opencl library. -Emil > -Emil > >> This was a build of Git 4ccff1499c with your branch applied on top of it. >> >> Cheers, >> Kai >> >> >> > _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
