LISTSERV 16.5 - XROOTD-DEV Archives

@adriansev Ah yeah, this is part of what I was talking about with regards to using a

$ docker run --rm neubauergroup/centos-build-base:3.8.11 'python --version --version && cmake --version' Python 3.8.11 (default, Aug 2 2021, 20:01:57) [GCC 8.3.1 20190311 (Red Hat 8.3.1-3)] cmake version 3.20.2 CMake suite maintained and supported by Kitware (kitware.com/cmake).

Yeah, I realize that is probably what most people are doing and that I'm on my own here a bit if I want to use anything beyond the default software included in CentOS 7, but I've been burned enough times by using the system Python for anything user related that I now always install my own CPython for use and leave the system Python alone for the OS to use by itself (to much happier results I might add!).

I realized I can get away with just setting PYTHON_EXECUTABLE in CMake to set everything else through FindPythonInterp (which is what I do when building ROOT) — so thanks @adriansev for helping me here remember to read the docs closely. 😄

There I now get the same behavior as I was seeing over on Debian during the build (XRootD Python bindings being built and installed, but under an atypical path in site-packages given the fall back to easy install)
