No module named 'minigl'

I am trying to convert my qtpyvcp app from linuxcnc 2.8 and debian 10 to run on linuxcnc 2.9 and debain 11.  I  get this error when I start it up
...
File "/home/cnc/dev/qtpyvcp/qtpyvcp/widgets/display_widgets/gcode_backplot/glcanon.py", line 19, in <module>from minigl import *ModuleNotFoundError: No module named 'minigl'

Apparently, the module minigl.so was not created during the linuxcnc or qtpyvcp builds and I don't know how to go about installing or compiling it.  Can someone please shed some light on this?

Thanks,
Butch Corley

Suggest you edit your UI and change the backplot to VTK and remove use of older (Axis style) back plot.

Cheers.

The VTK backplot has several limitations making it unsuitable for our plasma cutting application. For instance, there is no event for clicking on a line and returning the line #. Also, there doesn't appear to be any true 2 dimensional (X,Y) visual display. Further, I was able to modify the canon associated with the gcodepackplot so that I had crosshairs instead of a cone.

If I can't get the missing minigl issue resolved, I will most likely have to completely redo my GUI on a different platform such as QTVCP as it seems to have a more comprehensive backplot available. Unfortunately, for me, that is a ton of re-work since nearly all of the custom widgets are different, not to mention python handler file changes, postgui hal changes, and file location / system setup differences. But, hey, good practice, right?
