rpmbuild question, python3-graphviz example

Post by mathog » 2020/04/07 22:58:57

Our CentOS 7 systems have an RPM package graphviz-python-2.30.1-21.el7.x86_64 but there seems to be no CentOS 8 equivalent. Fedora has one with a vaguely similar name but it does not build as is, oddly demanding to also build a python2 version. Using the method shown below I eventually built and installed just the python3 version. Is there a way to do this with just some command line option at the first rpmbuild, something logically equivalent to

rpmbuild --rebuld --python3-only package.src.rpm

?

This was the long way used to build python3-graphviz, which, in the end, seems to be a different package altogether.

Code: Select all

#find src.rpm here:

Also, these do not appear to be the same packages. Their contents are:
