The problem is the driver itself. It looks like nobody finished implementing wglGetProcAddress(). It wouldn't be difficult to do. If you look at the OSMesa driver's OSMesaGetProcAddress() function, that's a good example of what's needed. If you can fix this I'll put the changes into Mesa for the next release. -Brian |
