>> rpm -q --whatrequires python-setuptools
no package requires python-setuptools


How reproducible:
always

Steps to Reproduce:
1. yum install python-devel

What is the actual problem? Why would python-devel need python-setuptools?

To create a python extension one installs python-devel to pull-in headers and sources of python.
However, to actually install and package the extension one still needs python-setuptools.
This BZ was suggested by me actually to enhance that workflow.
Maybe there could be a python development group that would require both the packages as dependencies instead?

Comment 4 Petr Viktorin 2016-03-14 14:42:36 UTC

Setuptools are quite useful, and I'd recommend them in most cases, but they're not the only way to build Python extensions. For example the "distutils" module can be used as well, as can alternative buildsystems like waf.
Also, python-devel is useful for other things than extensions, for example to embed Python in C programs.

The right thing to do for your package is to BuildRequire both python-devel and python-setuptools.

Thanks for trying to enhance the workflow, however!
