I’ve wrote an adequate little program in C that creates a window. However, I’m having trouble adding the OpenGL rendering context and assorted functions to it.

GetDC, ChoosePixelFormat, SetPixelFormat — all wgl functions, as I understand it. I thought these may be specific to Visual C++, but this does not seem to be the case — unless they’ve been radically altered to be C++ only; the amount of errors, compared to MinGW, is stunning.

Where can I find WGL?
How can I add it to MinGW?

    Downloading and installing the following libraries into MinGW/lib resolved all issues:

    win32api
    wing32
    GDI
    GDI32
    GDIPLUS
    OpenGL
    opengl32

    These are called in order by gcc. No longer are there undefined or contradictory define errors.

    Headers then need only be:
    GL/gl.h
    windows.h
