It is always the case that native tutorials are better than whatever of the
bindings. In the case of OpenGL, it is such a straightforward thing that
there would be no much difference between Ada, C or any other language
calls anyway.

I have no idea why existing Ada bindings are so difficult to make working.
Especially because there probably is no urgent need in having such bindings
at all. It is a long time since I programmed in OpenGL, but most of it
could be called using ad-hoc "pragma Convention (C," calls, because there
is not much meat behind its types anyway. I bet whatever problems the
poster had, were with libraries and gcc setup, not with Ada.

I also guess that this

https://gcc.gnu.org/onlinedocs/gnat_ugn_unw/Running-the-binding-generator.html#Running-the-binding-generator

might produce pretty good results for OpenGL, to start with or look at.
