Yes, you're right but it don't work.
I've already try it without success.
My header now is:
//#ifdef _APPLE_OPENGL_FRAMEWORK
//#include <OpenGL/gl.h>
//#include <OpenGL/glu.h>
//#else
#define GL_GLEXT_PROTOTYPES 1
#include <GL/gl.h>
#include <GL/glu.h>
//#endif
and i have always the same output.
I try to analize the glext.h and i see this:
----------------------------------- from glext.h
#ifndef GL_VERSION_2_0
#define GL_VERSION_2_0 1
#ifdef GL_GLEXT_PROTOTYPES
The GL_GLEXT_PROTOTYPES definition was checked only if GL_VERSION_2_0
wasn't defined before.
It's possible GL_VERSION_2_0 is already defined? (due a bug?)

Hi to all,
i'm writing an application based on opengl and i use GLSL for a
custom shader.
The application over mac osx compile and work correctly.
On linux I installed MESA 7 on my ubuntu feisty.
When i try to compile it i've this error

In my source files i've included the header so:
#ifdef _APPLE_OPENGL_FRAMEWORK // it's defined only under OSX
#include <OpenGL/gl.h>
#include <OpenGL/glu.h>
#else
#include <GL/gl.h>
#include <GL/glu.h>
#endif
and on my system:
[EMAIL PROTECTED]:~/workspace/netvideo$ sudo find / | grep "GL\/gl\.h"
/usr/local/include/GL/gl.h
[EMAIL PROTECTED]:~/workspace/netvideo$ Now, i wrong something... but what?
Prototypes for GL functions aren't enabled by default (to encourage
using glXGetProcAddress). To fix this, try defining
GL_GLEXT_PROTOTYPES=1 either on the cmd line (-
DGL_GLEXT_PROTOTYPES=1) or in your code (#define
GL_GLEXT_PROTOTYPES 1) before including GL/gl.h
