Are you sure that you get this error from GLXlink or did it come from
code initializing the GL window?
Anyway, you do want to be sure to call pfInitGLXGfx() instead of
pfInitGfx() since you are doing a GLX window.

Wade can comment on hints for adapting his code.

However, Performer does support running a program under GLX.
There are a couple of sample programs that demonstrate this in
        /usr/src/Performer/src/pguide/libpf/progs

                complex-glx.c - a most minimal roll-your-own glx example

                utilui.c - uses utilities in libpfutil for setting up
                        a GLX window and also for doing X input handling
                        asynchronously in a separate process.

        You can also look at /usr/src/Performer/src/lib/libpfutil/xwin.c
                to see how we set up GLX windows and call GLXlink.\
                Look at the routine pfuGLXCreateWindow().

        for even more glx exapmles, you can look in
                /usr/people/4Dgifts/examples/GLX/{gl-Xlib,glxwidget}
