Testing openGL / libGL library on CentOS 6.6

I think I may have a problem with my installation of openGL. I am working on a CentOS 6.6 cluster. I'm looking for canonical "hello world" type examples of openGL code.

It appears that these examples are 20+ years old and don't compile.

E.g. 

~$ gcc cube.c -lglut
/tmp/ccRTbnOw.o: In function `init':
cube.c:(.text+0x2d9): undefined reference to `gluPerspective'
cube.c:(.text+0x325): undefined reference to `gluLookAt'
collect2: error: ld returned 1 exit status

The openGL was installed in the mesa rpm : 

mesa-libGL-devel-10.1.2-2.el6.x86_64

Those are linker errors, it looks like it's compiling just fine.

You have to link against libGL & libGLU too:

gcc cube.c -lglut -lGL -lGLU
