Subject: [Emc-developers] building/running linuxcnc from source question

Hi,

I managed to compile linuxcnc from source and all the tests run successfully. I 
was wondering if anybody else got the following error. When I run the file 
./scripts/linuxcnc. I get the following error :

File "/home/marc/Documents/linuxcnc/linuxcnc/lib/python/glnav.py", line 118, in 
glRotateScene
   mat = [i for i in itertools.chain(*mat.tolist())]
AttributeError: 'c_double_Array_4_Array_4' object has no attribute 'tolist'

the error is fairly straight forward. I am just wondering if this is a bug or 
just that I have the wrong version of pyopengl.

I am running Ubuntu 20.04.3 LTS with an 5.10.59-rt52 kernel. I have pyopengl 
3.1.0 installed with python 3.8.10.

Regards,
Marc
