@lmoureaux : thanks for reporting this problem, well the `py_version_short` goes to https://github.com/xrootd/xrootd/blob/cbd73ee8ea77a89e8eccfc0e412ee1c5128ea47f/cmake/XRootDFindLibs.cmake#L127-L128 as `XRD_PYTHON_REQ_VERSION` so `sys.executable` won't do, but let me play a bit with it, maybe this could be a hint. -- You are receiving this because you are subscribed to this thread.
