Ceph » ceph-volume

ceph-volume fails to "build" when run via cmake on python 3.12 (on ubuntu 24.04).

The issue seems to be that setuptools is no longer part of the default bundle of packages in a virtualenv:

• https://github.com/python/cpython/issues/95299

I was successfully able to get past the issue with a hacky little change:

But I'm not really sure if that's the best way forward, especially if we don't want things in the build relying on internet access (and/or arbitrary versions). I'm not familiar with why ceph-volume is being "built" using a virtualenv because that isolates us from system packages (odd if we are building an rpm or deb IMO). So rather than trying to fix it myself, I'm filing a tracker so we can discuss it later.
