    The header file is <GL/GLaux> not <GL/GLuax>

    float armAngle[2] = {0.0f, 0.0f);
    That, obviously should be ended with '}' as opposed to ')' but I know it's hard to mistake the two on higher resolutions.
    glTranslate()
    The function is glTranslatef();

    You can use plane simple typecasting for that.

    Yeah, well if you look 1 post above that one, you'lle see i gave
    you this answer already, not demand the honor or anything .

    I still recommand using a true Win32 program instead of a
    console app with that pragma line.
