I''m sorry if this has been explained in some erlier post, I''d use search to find out but it''s temporarly disabled (anyone knows when it''ll be back?) so i can''t. I''m having problems with including standard headers like the gl.h For example I got this class, CSprite, in CSprite.h that needs the gl.h file, then I got the class CObject, that needs to include CSprite.h and use the gl.h and then finaly CObject.h needs to be included in main.h that also needs the gl.h. When I try to include gl.h in all needed files I often get compiler errors that complain of errors inside the gl.h file. Obvius this is casue I have include it wrong somewhere, casue if I only include it in one file things work fine (except of course that I can''t use the other two classes). What is the correct way to include gl.h?

What are the errors you are referring to? Are you linking the proper libraries?

Microsoft''s gl.h requires that windows.h be included before it. Do something like this:

#ifdef _WIN32  #include <windows.h>#endif#include <GL/gl.h>

Is that your problem?

Thanks Null, that was it
