I remembered this issue on bpo with contracting opinions from when I first looked in 2019.

Hi,

This script is currently not written in Python and hardcodes paths that are incorrect on virtual environments and relocated installs, so it would make sense to rewrite it in Python, using sysconfig.

That does not require it to be exposed as a module, but would be a very cheap improvement.

As the bulk of the work would be to actually rewriting it in Python, and as there is reasoning to do this other than just exposing it as a module, I would be +1 FWIW.

Note that the original python implementation is still in the repository and is used for framework builds on macOS because of the hardcoded values in the shell script variant. On macOS the sysconfig values for compiler related settings (CC, CFLAGS, …) are adjusted dynamically to account for different compilers and system versions.

IIRC the shell script variant was introduced to support some cross compilation scenario’s  (see https://bugs.python.org/issue16235).

Ah! I noticed the presence of a Python python-config in the repo shortly after sending this, but I was missing the this context here, so thank thank you :) So, I guess the existing python-config script just needs to be updated to handle cross compilation properly. Cheers, Filipe Laíns
