Failed to run %check secion

[pkking]

What i run:

pyp2spec -t types-toml
spectool -RSg python-types-toml.spec
rpmbuild -br python-types-toml.spec
yum-builddep /root/rpmbuild/SRPMS/python-types-toml-0.10.8.1-1.fc35.src.rpm 
rpmbuild -ba python-types-toml.spec

And i got:

It looks like this project only contains the typing stubs (.pyi files, not .py) so there's nothing to import during the %check phase of the package build. To build the package as RPM you should edit the generated python-types-toml.spec file and remove the %check section entirely.

FTR we tried to mitigate a similar but different issue via https://src.fedoraproject.org/rpms/pyproject-rpm-macros/c/fa49bf2efbcb01e9b80a592d24073e1afa6acd0c?branch=rawhide

[befeleme]

True. To make the build of such packages seamless, we could change the behavior of %pyproject_check_import and accept it when it doesn't detect any modules. I wouldn't make it default though, this could be something possible to use in related projects, similarly like pyp2spec invokes %pyproject_save_files '*' +auto but forbidden in the actual distribution.

[hroncok]

Possibly. That would enable automatic copr build of packages without Python modules.
