How to reliably compile on Linux Mint 22?

[Evert-Homan]

So far I have never succeeded to succesfully compile PyMol on any system. Here I tried it again on Linux Mint 22, following the description here: https://pymolwiki.org/index.php/Linux_Install.

There are some warnings but no red errors, and compilation finishes without any obvious issues. Then when I try to start PyMOL I get:

~/pymol-open-source-build/bin$ ./pymol

/usr/bin/python3: can't open file '/usr/local/lib/python3.12/dist-packages/pymol/__init__.py': [Errno 2] No such file or directory

I am aware there is a PyMOL 2.5 deb package but I found that this version crashed easily for non-obvious reasons.

Please advise on how to resolve this. Thanks/Evert

Apologies, the wiki page still needs to be updated, and I'm extremely behind on updating the info here.

pymol-open-source/INSTALL

Lines 52 to 56 in 9b9cd6f

	Clean build and installation
	pip install .
	Recommended for developers (build output, incremental build, and building C++ unit tests)
	pip install --verbose --no-build-isolation --config-settings testing=True .

is the most to date instructions that don't call setup.py directly and uses pip instead. Also, see our linux CI for a working example:

pymol-open-source/.github/workflows/build.yml

Lines 45 to 48 in 9b9cd6f

	- name: Build
	run: |
	pip install --upgrade pip
	pip install -v --config-settings testing=True .

pip install .

Should I run this just in the cloned repo, or what?
