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: https://github.com/python-cffi/cffi/issues/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.

@minrk has a patch that builds:

https://github.com/hynek/argon2-cffi-bindings/compare/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.
