7.3. Using automatically generated dependencies for Python RPMs

You can automatically generate dependencies for Python RPMs by using upstream-provided metadata.

Prerequisites

A spec file for the RPM exists. For more information, see A spec file description for an example Python package.

Procedure

Include one of the following directories in the resulting RPM:
- .dist-info
- .egg-info
  The RPM build process automatically generates virtual pythonX.Ydist provides from these directories, for example:
  python3.12dist(pello)
  The Python dependency generator then reads the upstream metadata and generates runtime requirements for each RPM package using the generated pythonX.Ydist virtual provides. Example of a generated requirements tag:
  Requires: python3.12dist(requests)
Inspect the generated Requires.
To remove some of the generated Requires, modify the upstream-provided metadata in the %prep section of the spec file.
To disable the automatic requirements generator, include the %{?python_disable_dependency_generator} macro above the main package’s %description declaration.
