BUG: scipy 1.9 build issue
See original GitHub issueDescribe your issue.
We build scipy and scikit-learn from source.
With scipy 1.9, scikit-learn build always failed immediately with log below.
We also tried python3 -c 'from scipy.lib import _ccallback_c' and that failed in the same way.
This wasn’t an issue in 1.8 or even earlier version.
If we build lower version first and gradually upgrade, it works fine, indicating probably some file is left there.
Reproducing Code Example
Bascially python3 -m pip install on locally cloned repo of scipy/scikit-learn

I can close now and reopen if I got this again, thanks again for the quick help~!
That could indeed explain an issue going away. You filed the issue on Oct 9th, while there were bug fix releases for both
mesonandmeson-pythonon Oct 5th with fixes relevant to SciPy builds.Do you want to test more, or close this issue now and reopen in case it comes back?
