Can you post more info about the context? Like you were executing, the call stack, whatever. Also, check that you have the opengl lib path correctly set going to system settings -> FFI.

Also, some things I forgot to mention:

1. The generated glX functions list has wrong case. All function names start with glx but should start with glX.

2. I also made the library path a setting that appears in system settings. This is cool because before library names where fixed in code, but on each system can be different.

I get Error: function unavailable with Pharo1.3 and 1.4, but I probably followed the steps wrong. I first loaded a fresh image, then did Gofer it squeaksource: 'NBOpenGL'; package: 'ConfigurationOfNBOpenGL'; load.
ConfigurationOfNBOpenGL project lastVersion load, as per previous instructions somewhere else, then loaded the latest NBXLib + examples from squeaksource via montecello, then latest NBOpengl-X similarly.
