what constitute openGL?  i.e. which libraries make up what is called
'openGL' ?

I am used to seeing an architecture diagram for applications, as
building blocks, so I know what depends on what, and what libraries
make up what block in the diagram. The apps at the top, and blocks
below it, and such.

If I understand more the architecture used here, I might be able
to figure what is the problem with this binding in terms of
mismatched libraries.

Right now, I just have lots .so's that I installed from packages. But
I really do not know which of these is openGL and which is what. And
I do not know what versions. I just use linux mint package manager
to install things. I assume it knows the correct versions to install.

DO you have an example of what other openGL I can try? I never done openGL
before.

I do run your demos on windows, and they run with no problem. But
not on Linux mint as you can see.
