Well I'm quite sure you are not linking the OpenGL library to your project. I'm not an OpenGL user but these kinds of errors usually occur when you do not link something. You obviously include the necessary header files because the compiler knows about those functions. Again , I believe it's a linking problem
Exactly, you need to add either "OpenGL32.lib GLU32.lib" to your linker options in Visual C++, or "-lGL -lGLU" for GCC compilers.
But usually the projects should run out of the box.. Can you please tell me which one you downloaded?
