I am taking a look at this issue. The problem as I see it is that the `python3.X-dev` package is not installed, which leads to the message below during configuration: ``` -- Found PythonInterp: /venv/bin/python3.7 (found suitable version "3.7.5", minimum required is "3.7") -- Could NOT find PythonLibs (missing: PYTHON_LIBRARIES PYTHON_INCLUDE_DIRS) (Required is at least version "3.7") ``` Due to this you'd see the error as reported. The way to solve is to install the required dependency first (i.e. `python3.7-dev` in this case), then it works fine. I'm tempted to close this, unless it's customary to declare `python3-dev` as dependency in `setup.py` -- Reply to this email directly or view it on GitHub: https://github.com/xrootd/xrootd/issues/1474#issuecomment-1427912790 You are receiving this because you are subscribed to this thread.
