Newbie (stupid) question

hi all,
i have a puzzling problem:
i am tring to write a small vertex/fragment shader, so i am using the *_PROGRAM_ARB stuff.
i included the glext.h file (and i downloaded the latest release from the oss site). Still when i tri to compile&link my program it keeps me sayng:

[enrico@client4 render]$ make
g++ -g -c eptagon.cpp
eptagon.cpp: In function GLuint load_program(char*, unsigned int)': eptagon.cpp:94: GL_FRAGMENT_PROGRAM_ARB’ undeclared (first use this function)
eptagon.cpp:94: (Each undeclared identifier is reported only once for each
function it appears in.)
eptagon.cpp:98: glGenProgramsARB' undeclared (first use this function) eptagon.cpp:100: glBindProgramARB’ undeclared (first use this function)
eptagon.cpp:103: `glProgramStringARB’ undeclared (first use this function)
make: *** [eptagon.o] Error 1

now where am i wrong? All glSomethingARB functions should be declared/defined in glext.h, right? What else am I missing? I am including glut.h too (and just to be safe gl.h and glu.h).
If anyone has some hints, lemme know. Thanks for the help, bye

Are you sure that you have the newest glext.h?

Try download this own, should include ARB_vertex_program and ARB_fragment_program:

thanks for the advice, corral,
anyway i already had the latest glext.h

however i solved the problem adding a


before any other #include in my program, so now it look like:

#include <stdio.h>


#include <GL/glut.h>
#include <GL/gl.h>
#include <GL/glu.h>
#include <stdlib.h>
#include “glext.h”
#include <string.h>
#include “eptagon.h”

the only thing i can’t understand yet is why it won’t read the definition of

GL_FRAGMENT_PROGRAM_ARB from the glext file.
I have to define it explicity in my code.
Thanks again and bye!
