How to reach OpenGL?

Hello, I’m sorry. Please, execuse me for not replying for a long time.

Why not simply use glGetString in your program and print it out to see
what is used at runtime?

Output from glGetString(GL_VENDOR), glGetString(GL_VERSON), and glGetString(GL_RENDEER):

OpenGL vendor: ATI Technologies Inc…
OpenGL version: 4.3.12618 Compatibility Profile Context 13.251.
OpenGL renderer: AMD Radeon HD 7600M Series.

So, why ouput from rpm -qf /usr/X11R6/lib64/ was, “file /usr/X11R6/lib64/ is not owned by any package”?

Why not contact Sebastian direct and ask him?

I found Sebastian1969, SebastianHa, SebastianHilbert, Sebastian Hillizeck, and Sebastion_Mue.
