Looks like GLU 1.1 (the old Mesa version). SGI's GLU 1.3 is what you want. It's been included with the normal Mesa distro for quite a while now. If you download Mesa 4.0.3 you can build a new libGLU.so.1.3 and replace your old one. -Brian ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Gadgets, caffeine, t-shirts, fun stuff. http://thinkgeek.com/sf _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
