Issue with installation on Windows

[Oscar Chen]

I've been trying to download and use SLiMgui on a laptop with Windows 10 Enterprise N. Following the instructions on the manual, I've been able to download it with msys2, but once I open SLiMgui.exe, I get the error message pasted down below from msys64, with SLiMgui opening but the window remaining all black.

Hi Oscar!

This looks like an error coming from deep inside the Qt framework.  It's not SLiM code, and it's not even Qt code that SLiM calls directly (SLiMgui does not use QOpenGLShader directly).  I'd suggest trying things like reinstalling Qt, installing a different version of Qt, etc.  It's a problem with that framework, nothing to do with SLiM.  (A very strange problem, too, I'd note – a syntax error in a shader program??  I wonder if there's some kind of video card incompatibility or something.)

Good luck!

Cheers,
-B.
