including header files
Most OpenGL programs and applications that only use the standard
OpenGL data types, definitions, and function declarations, need only
include the header file gl.h under the
/opt/graphics/OpenGL/include/GL
directory. Use the following
syntax:
#include <GL/gl.h>
Still other header files may be needed by your program, depending on
your application. For example, in order to use the OpenGL extension to X
Windows (GLX) you must include
glx.h
, as shown below.
#include <GL/glx.h>
Instructions for including various additional header files are usually
provided with the
README
file that accompanies a utility or function. The
README
also includes instructions for using or operating the utilities.
Your header file declarations at the beginning of your program should
look similar to this:
#include <sys/types.h>
#include <stdio.h>
#include <string.h>
#include <X11/X.h>
#include <X11/Xlib.h>
#include <X11/Xutil.h>
#include <GL/gl.h>
#include <GL/glx.h>
