I seem to have some problems building the Python bindings on my Ubuntu 22.04 LTS setup. Running the Python test yields the output below. A similar error occurs if I do python3 setup.py install --user followed by python3 -c 'import weggli'. When another person tried it though it worked so it's not always. Might be something broken with my environment but posting it here for future reference and my debugging efforts.

$ python3 setup.py test

Can you try to build with rustc 1.60.0 ? It looks like a change in 1.61.0 broke the Python build: https://github.com/rust-lang/rust/blob/1.61.0/RELEASES.md#compatibility-notes

Yup, this seems to be the problem. 1.60.0 works, 1.61.0 fails. So we need to change some details about how the linking is done?
