Re: problem with simplepore live visualization

[Jean-Noël Grad]

Hi all,

After discussing the issue with Le Qiao further, we determined the issue 
was due to a bug in the ESPResSo visualizer, which will be fixed by this 
PR:
https://github.com/espressomd/espresso/pull/4691
Le Qiao confirmed the PR resolves the issue on his end. We will add it 
to the 4.2.1 bugfix release.

What I and David could not determine is why brew installing freeglut 
doesn't make OpenGL.GLE.gleSetNumSides available. If anyone on this 
mailing list knows which package to install on macOS to get 
OpenGL.GLE.gleSetNumSides to work, feel free to share it here :)

Best,
JN
