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.)
