QOpenGLShaderProgram: could not create shader program, QOpenGLShader: could not create shader, Could not link shader program X11 from a Mac XQuartz

SLimGUI version 4.0.1 from Messerlab, seg faults and coredumps when using a Mac and XQuartz trying to open via X11 on a RHEL 8 cluster. There is a closed issue at their Git page blaming Qt. Could it really be this XQuartz bug?

Is there a work around for this? We do see version 5.12.5-6 is available via dnf update.

Hi,
Did you consider using the Qt online installer so you can build SLimGUI with a more recent version of Qt ?

@SGaist No would that create a SLimGUI that could be then uploaded the our server as a module that could be loaded ad hoc? Or is what is created only then for use on a Mac?

The suggestion is to built it in a Linux machine so that you can then use it on your target.
