Hi @henryiii, thanks for the comments. I tried to use ```python try: import setuptools except ImportError: pass from distutils.core import setup, Extension from distutils import sysconfig ``` but unfortunately this still fails in some cases. The idea is to use `import setuptools` to override `distutils` when that's available. I also tried a variant in which I do `from setuptools import setup, Extension` then just `import sysconfig`, but that also didn't work everywhere. Tomorrow I will try to debug the failures and find a solution, but in the longer term, I think I will just take some time to write new python packaging code following [PEP 517](https://peps.python.org/pep-0517/) and [PEP 632](https://peps.python.org/pep-0632/), dropping usage of deprecated stuff altogether. -- Reply to this email directly or view it on GitHub: https://github.com/xrootd/xrootd/issues/1830#issuecomment-1332657316 You are receiving this because you are subscribed to this thread.
