[C++] Problem when including a header

Hi, I've got a weird error when including a header file. In my game, I have theese files: CBall.h:

#ifndef __CBALL_H__
#define __CBALL_H__


#include "SDL/SDL.h"
#include "SDL/SDL_mixer.h"

#include "CGame.h"
#include "CVector.h"
#include "CAnimation.h"


enum {
        POS_CENTER = -1
};

So, if in CBall.h, line 8, I don't #include "CGame.h", the game compiles and runs perfectly. But now I need to have a refference to the game object inside each ball (in order to change the state of the game when certain events happen to the ball), so I included "CGame.h", without using any Game object inside CBall.h or CBall.cpp (all refferences are commented out). Then, when I try to make my source, I get this:

I can't imagine what's happening, but I think it must be some kind of stupid error. Does anyone know this type of error? Can anyone help me? [Edited by - RazZziel on October 31, 2006 10:39:20 AM]
