Multiple python3 versions inside RPM package with .spec file

Question

I am trying to build a RPM package with two added python3 versions. I have built a Docker container that is using Rockylinux 8 that comes with python3.6. Now I added two more versions 3.9 and 3.11 using:

dnf download --source python3.11-requests
rpm -ivh python3.11-requests-2.28.1-1.el8.src.rpm

and:

dnf download --source python39-requests
rpm -ivh python-requests-2.25.0-2.module+el8.8.0+1554+fb04b4e8.src.rpm

This is the .spec file that I am using but if I try to build it, it builds it with only version 3.11 and ommit 3.9:

%global underscore() %(echo %1 | sed 's/-/_/g')

What am I doing wrong? Thx!

Answer 1

I think I achieved what I wanted. With this adjusted code I got two python3 packages with versions that I need, python3-3.11-fake-library-0.6.1-1.el8.noarch.rpm and python3-3.9-fake-library-0.6.1-1.el8.noarch.rpm.

%global underscore() %(echo %1 | sed 's/-/_/g')

%global python3_pkgversion_1 3.9
%global python3_pkgversion_2 3.11
