P2D Fails

[vsquared]

Is this a known problem or is it a problem with my system?

def settings():
  size(200,200,P2D)

Error msg:
java.lang.UnsatisfiedLinkError: Couldn't load library 'gluegen_rt' generically including [], nor as [/Users/s/.cache/py5/processing-libraries/javafx/library/macos-aarch64/libgluegen_rt.dylib, /Users/s/.cache/py5/processing-libraries/javafx/library/macos-aarch64/gluegen_rt, /Users/s/Python/venv/lib/python3.10/site-packages/py5/natives/macos-aarch64/libgluegen_rt.dylib, /Users/s/Python/venv/lib/python3.10/site-packages/py5/natives/macos-aarch64/gluegen_rt, /Users/s/py5_code/libgluegen_rt.dylib, /Users/s/py5_code/gluegen_rt, /Users/s/py

The P2D renderer should work just fine. It should find the gluegen native libraries in site-packages/py5/natives. Can you look in that folder and see if they are there? But there is no macos-aarch64 folder in there. Older versions of py5 had that folder but when py5 rejoined the official Processing distribution a few releases ago it became macosx-universal. Somehow you might have a py5 distribution that mixes up files from different versions.

The reason that it fails on Thonny is due to the what's already been discussed (but not what you checked as the answer). It's looking for py5/natives/macos-aarch64 in venv and it's not there. What is there is macosx-universal due to a decision to change the name. Somebody forgot to tell Thonny.

py5/natives folder:

OK, answer unmarked.

Now, can you remove (rename if you prefer) this whole Python folder that is outside Thonny at /Users/steve/Python/ and restart with a fresh Thonny and a new py5 install?
I would search for further stray installs...

[vsquared]

I'm still trying to figure it out. That Python folder has lots of my old python and py5 files in it and I really don't want to throw all that away. It also contains venv which I've already proven will mess things up for Thonny if I remove it. Tomorrow's a busy day for me so I will work on it some more when I get time. Starting over is a good idea if I can figure out how to do it with minimal collateral damage. It's interesting that Thonny has the requisite folder at /Users/steve/Library/Thonny/plugins/lib/python/site-packages/py5/natives but doesn't look for it there:

No, it has nothing to do with Thonny. You've mixed py5 source code from two different library versions.

The name change was from a recent Processing release.

Python envs can and will sometimes break and it is usually impossible to fix them. You should always be prepared to rebuild them from scratch. In professional settings people have several envs for different projects, so that it becomes easier to dump and rebuild a broken one. Thonny can make new envs and you can switch between them either from the interpreter tab at the preferences or clicking at the status bar on the bottom right.  I think that getting a pristine Thonny install and env is the only way of tackling this issue. I'm afraid I should be working on my PhD thesis... I'll try to avoid this discussion for a while. Good luck!
