Re: OpenGL renders incorrectly


Let the plain truth be known: there is _no_ cygwin implementation of OpenGL. The OpenGL package for Cygwin contains only headers that allow gcc to correctly link with the opengl32.dll that comes with Windows or the one that has been installed with your video card drivers. It is the exact same implementation of OpenGL that is used by VC++.

So if there is a run time error with your program with gcc but not with VC++ on the same computer, it can only be a fault with how OpenGL is called, not with how OpenGL is implemented. One likely cause is uninitialized variables that luckily get proper values with VC++, but not with gcc.
