Hi all,
I'm having trouble compiling open source Pymol 2.4.
If I compile with python 2.7, the compilation finishes without errors or
warnings, but when I start Pymol, I don't see the menu bar at the top of the
window, and I don't see any errors.
If, on the other hand, I compile with python 3, Pymol starts and I see the menu
bar, but I get warnings in the Pymol console that are related to a version
conflict of python 3 used for compilation and python 2 used in some scripts,
e.g. the ones shown below.
What's the python version to use for compiling, and how do I best proceed?
Thanks
Markus
This is part of the output shown in the Pymol console on startup:
