I’m still (slowly) working on getting cadquery to work on aarch64-darwin.
I’ve never figured out how to build OCP (which I think requires a newer MacOS SDK than nixpkgs offers), but someone recently made a wheel available for aarch64-darwin, so I’ve made it a lot farther!
Curiously, the below flake builds for me, and runs in jupyter – hooray!
Oddly, it segfaults when I try to run it from the console.

If I uncomment even just the import check:
$ nix build .#cadquery
...
Check whether the following modules can be imported: cadquery
/nix/store/6p3h1n7hmgymb7gm6yh9zvm6dckxfg0x-python-imports-check-hook.sh/nix-support/setup-hook: line 10: 89952 Segmentation fault: 11 /nix/store/7b0rz3bnx7msw2wawkv1hhn5lqf1b0wi-python3-3.11.6/bin/python3.11 -c 'import os; import importlib; list(map(lambda mod: importlib.import_module(mod), os.environ["pythonImportsCheck"].split()))'
If I comment out the checks for cadquery (the pytest and import check), it builds and runs fine, and jupyterlab is able to import cadquery, and it seems to work!
$ nix build .#cadquery
$ nix build
$ otool -L result/bin/python
result/bin/python:
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1292.60.1)
$ ./result/bin/python -m jupyterlab
But oddly importing from the python interpreter fails with a segfault (as expected with the failure of the import check):
$ ./result/bin/python -c 'import cadquery'
Segmentation fault: 11
I’ve uploaded ./result/bin/python -v -c 'import cadquery' to gist:bf7654c1871d384a966d0b1eb6633793 · GitHub; I’m not sure if the permission denied errors for creating .pyc (or was it __pycache__) files are relevant?
Any ideas why this module would run fine in jupyterlab but fail to even import (segfault) from the interpreter?
