Can't make an OpenGL program

[Bill Ramsay]

I am new to both OpenGL and GCC, but not to C/C++.    I am including 
<GL/glut.h>, which is where it
is supposed to be  (usr/include/GL under RH Linux 7.3) and apparently 
the file is being found.     But when
I run make or just compile I get an undefined reference for every method 
I'm trying to use in glut.h.

The file looks fine and the methods are defined.    

What am I doing wrong?
