OpenGL 1.2 GLimp_init() could not load openGL subsystem

[Astal4]

Hello, I am attempting to run io quake 3 on my SunBlade 2000 under Solaris 10, it is an UltraSPARC III Cu system, and the game compiles fine minus a few warnings as errors, I have got a build which appears to work, and it'll give the X window for the error and everything appears to be proper.

I am running an XVR-500 video card which is OpenGL 1.2 compliant, even with the OpenGL1 renderer however it fails to initialize the OpenGL system.

Compiled with GCC 8.5 and GNU Binutils 2.39, SDL version 2.27.0, I have verified the OpenGL system works fine via some built in openwindows tools.

I have tried running with various resolutions, and nothing seems to allow it to initialize, SDL2 has an X11 driver and OpenGL support built, all of this is 64 bit big endian.

Any more information wanted, just let me know and I can send it in.

Update: Rebuilt SDL2 and got the OpenGL init to go away, now it's the classic "Z_Free: freed a pointer without ZONEID" error.
