From 66c9e156860d01403e849cd4775836af20c5fc6d Mon Sep 17 00:00:00 2001 From: Rich Ercolani <214141+rincebrain@users.noreply.github.com> Date: Tue, 8 Jun 2021 20:20:16 -0400 Subject: [PATCH] Correct a flaw in the Python 3 version checking It turns out the ax_python_devel.m4 version check assumes that ("3.X+1.0" >= "3.X.0") is True in Python, which is not when X+1 is 10 or above and X is not. (Also presumably X+1=100 and ...) So let's remake the check to behave consistently, using the "packaging" or (if absent) the "distlib" modules. (Also, update the Github workflows to use the new packages.)
