Hi Dan,
thanks for reporting this. So I guess this check probably affects
anybody using Mesa. It checks the supported compatibility profile
version which seems to be 3.0 for Mesa.
I updated the package to handle the X error that occurs when OpenGL
context creation fails instead of checking for the OpenGL version. Could
you give it a try?

Would also be nice to test this on a machine without OpenGL 3.2 support.
I only tested the error handling by trying to create an OpenGL 4.0
context on a system using Mesa.
Best,
Tobias

When using higan with an OpenGL 3.3 capable Gallium3D driver, it fails the
OpenGL version check introduced in check-opengl-version.patch.
When I build higan from the vanilla source, it runs fine with OpenGL backend.
I'm guessing the glVersion is returning the compatibility context version
rather than the core one?
Graphics card on this system is a RadeonHD 4550, and another system with an
8400GS also has this issue when using nouveau.
