[scl.org] rh-python36-build alternative in rhel

Tue Nov 28 12:47:29 UTC 2017

Hi,

according to this (
https://developers.redhat.com/blog/2014/12/04/add-packages-to-python-2-7-software-collection/
), I'm trying to create my own extension of the rh-python36, though
doesn't build:

+ '[' '%{buildarch}' = noarch ']'
+ QA_CHECK_RPATHS=1
+ case "${QA_CHECK_RPATHS:-}" in
+ /usr/lib/rpm/check-rpaths
+ /usr/lib/rpm/check-buildroot
+ '%{rh-python36_os_install_post}'
/var/tmp/rpm-tmp.k3bzOV: line 316: fg: no job control
error: Bad exit status from /var/tmp/rpm-tmp.k3bzOV (%install)

most probably because the variables are not expanded?
What did I miss? Specfile for refenrence in attachement.

also, just to confirm, is this the right way to create those packages
and make the applications depend on this scl, right?

Thanks in advance,
Gh.
