• The package is maintained in this repository.
• I understand that issues related to the base OpenWrt repository or LuCI repository will be closed.
• I am reporting an issue for OpenWrt, not an unsupported fork.

Old issue : #28196

[commodo]

Is this with a clean build?

Buildbots are not catching this error.
And I've built cryptography a couple of times locally and did not see it.

It's basically an issue with include directories in setuptools where the host include dirs were picked up during build instead of the target's include directories.

[grosjo]

Yes, this is a clean built

[grosjo]

@commodo Can I help you somehow to resolve this ? (not technically good enough but maybe something else)

[commodo]

Struggling to reproduce.

I have a suspicion.
Maybe you have libpython3-dev on your system.
That has caused issues in the past.

I'll try a docker image to test.

If you have more info/context, it would help.
Even a Dockerfile + script that reproduces the issue would help.
