I'm following the instructions at http://wiki.winehq.org/RegressionTesting to find the problem that stopped a series of my games from working, but when I run Code: CC="ccache gcc" ./configure --verbose Everything goes fine except at the end an error is produced: "configure: WARNING: No OpenGL library found on this system. OpenGL and Direct3D won't be supported." I know the games that I'm trying to fix use DirectX, so I can't proceed without fixing this problem. I've also tried Code: sudo apt-get build-dep wine wine-dev and it grabbed alot of stuff but the OpenGL problem persists. I've got an NVIDIA card and my drivers were installed through Envy; most graphics-acceleration applications run fine (eg Compiz). What package specifically should I be looking for?
