Can't compile OpenGL project under OSX

There's an OpenGL project I have to work on for a course I am attending. There were link errors due to GLEW. After some research, I found out that on OSX GLEW is not necessary.

I included following headers.

//#include "CL/cl_gl.h"
#include <OpenGL/glu.h>
#include <OpenGL/gl.h>
//#include <OpenGL/glext.h> 
//#include <GLUT/glut.h>

But I am still getting compile errors of following kind:

  use of undeclared identifier 'GL_TEXTURE_BUFFER_EXT'
    glBindTexture(GL_TEXTURE_BUFFER_EXT, 0);
                  ^

Where on OSX is the GLenum GL_TEXTURE_BUFFER_EXT resp. GL_TEXTURE_BUFFER defined?

The EXT variant will only be defined in glext.h or the headers which come or are generated by the various GL extenstion loaders. The actual GL_TEXTURE_BUFFER enum is defined in OpenGL/gl3.h. On OSX, modern GL is part of the OS, and you can directly link the modern GL funtions. However, I would still recommend using some GL loader, just for portability reasons.
