Error while compiling

OpenGL OpenGL: Basic Coding

Hi eveyone

My Program was working Just fine, but I don’t know what happened!
I get this creepy error message. what’s it all about guys?


1>------ Build started: Project: 3D2, Configuration: Debug Win32 ------

P.S: I use microsft visual c++ 2008 express edition

“gl.h included before glee.h”
Can you post the 3D2.cpp top part here?

Here It is


#include "stdafx.h"
#include "GL\glut.h"
#include "math.h"
#include "..\..\H\math3d.h"
#include "..\..\H\glframe.h"
#include "..\..\H\gltools.h"
//#include "SDL_image.h"
#include "GL\gl.h"

I also found this piece of code in Glee.h. I thought It might help.


#ifndef __glee_h_
#define __glee_h_

#ifdef __gl_h_
	#error gl.h included before glee.h
#endif

I don’t see Glee being included anywhere…

Yeah, Because glee.h is included in gltools.h . here it is:
gltools.h :


#ifndef __GLTOOLS__LIBRARY
#define __GLTOOLS__LIBRARY

#define FREEGLUT_STATIC

// Bring in OpenGL 
// Windows
#ifdef WIN32
#include <windows.h>		// Must have for Windows platform builds
#include <gl\gl.h>			// Microsoft OpenGL headers (version 1.1 by themselves)
#include "glee.h"			// OpenGL Extension "autoloader"

#include <gl\glu.h>			// OpenGL Utilities
#include "glut.h"			// Glut (Free-Glut on Windows)
#endif

That’s weird d to me!
I changed the Include Order to this order and for now everything is OK !


#include "stdafx.h"
#include "..\..\H\gltools.h"
#include "..\..\H\math3d.h"
#include "..\..\H\glframe.h"
#include "math.h"
#include "GL\glut.h"
#include "GL\gl.h"

I didn’t know the order of Includes is THAT important in coding
Thanx anyway DmitryM

Well, that was what Glee complained initially:
“gl.h included before glee.h”

I’m glad you solved it.
