Using GL routines

[Shyam Mittur]

I am trying to run a GL based program on a base-configuration RS/6000 Model 320 with a color controller (no SGI graphics adapter) and get the following
startup error:

gl: winopen: 1345-072 The requested X-Windows Server extension is not installed

Does this mean GL based programs can be run only with the high-end adapter, or
do I need to change something in the X window system installation?  My local 
IBM support person seemed to think the former was the case, but I am not sure
he understood what was going on.

I tried the examples "sniff.c" and "primer2.c" in /usr/lpp/ibmgl/examples, 
as well as the following small variant, all with the same results:

       ginit();
       clear ();
       gexit ();

Has anybody tried these examples?
