I am trying to perform off-screen rendering in an application which
uses OpenGL via FLTK. I am mostly programming by tutorials and
examples.
One of the ways to setup off-screen rendering is by a frame-buffer
object. I was reading this tutorial: http://www.gamedev.net/reference/articles/article2331.asp
which walks you through setting it up. I tried to do this in my
program, but it just comes up with undefined references to the
functions. I have the following header files included... which one am
I missing?

#include <FL/Fl.H>
#include <FL/Fl_Gl_Window.H>
#include <FL/gl.h>
#include <GL/glu.h>
One of the errors I get:
error C3861: 'glGenFramebuffersEXT': identifier not found
I have looked around and did not find any specific examples aimed at
off-screen rendering in fltk

It's an extension, you have to get a pointer to the function
using wglGetProcAddress (on Windows...)
Google for "opengl extensions" for more info.
