I'm traveling right now, but I believe the problem is that mesa does not install a glew.pc pkgconfig file. You can create one from the glu.pc example (or one of the others) and install it in /usr/lib/pkgconfig (for x86) or /usr/lib64/pkgconfig (for x86-64). The check for glew in the demos configure script would be something like: PKG_CHECK_MODULES([GLEW], [glew]) This would search for glew.pc and then the flags would be stored in GLEW_CFLAGS and GLEW_LIBS. I don't have a chance to fix this for another week or so, but it needs a little fixing on the mesa side for glew to be a fully installed library like gl or glu. -- Dan _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
