Finally, found a fix for the GL API errors on Linux

Uh, the 'gl_data.cpp' changes in your commit were not in the patch I attached ... added accidentally?

[Graf Zahl]

They were supposed to be a separate commit but it got mixed up. I thought making the sprite offset definition file available to PWADs would be a good idea after noticing that Back to Saturn X had replaced the complete sprite set of the IWAD.

I have glew installed but it seems the gzdoom binary isn't being linked to it.

[Graf Zahl]

I think it only uses the headers. It sure doesn't need any of the dynamically loaded functions.

Thanks for all the fixes, no need for my patch nor forcing linking to libdl (which was also fixed in zdoom) and libGLEW anymore.

I guess this can be closed now.
