What am I supposed to make of this? I don't know what you're trying to do, on what platform, using what commands. Your installer should be able to use argon2-cffi-bindings's wheels that work fine on all platforms that I have access to. Why it doesn't is not apparent from what you shared.

[hynek]

Thank you for the update – so it's Conda and you're attempting a free-threaded build?

It looks like those aren't supported by CFFI yet, so I don't think I can do anything about it for now: python-cffi/cffi#126

linux-64/python-3.13.0rc2-h6355ac2_1_cp313t.conda In this version (Threading), it gives an installation error in this version.

linux-64/python-3.13.0rc2-h9ebbce0_101_cp313.conda There is no problem with this version.

They worked there when I copied the modules I installed here to the other side.

[tacaswell]

@minrk has a patch that builds:

main...minrk:argon2-cffi-bindings:313t

I have been using this branch locally, but I'm not clear how I found it.

The downside is that with 313+jit that branch hangs in build.

Yeah, same when trying to do this on tox, https://github.com/tox-dev/tox/actions/runs/14999479501/job/42142296713?pr=3526 but seems is because of python/cpython#111506
