1706 PROC X11DRV_wglGetProcAddress(LPCSTR lpszProc)
1707 {
1708     int i, j;
1709     const WineGLExtension *ext;
1710 
1711     int padding = 32 - strlen(lpszProc);
1712     if (padding < 0)
1713         padding = 0;
1714 
1715     if (!has_opengl()) {
1716         ERR("No libGL on this box - disabling OpenGL support !\n");
1717         return 0;
1718     }

I'm sorry but I don't understand what it means or how should I resolve my
problem with it.
