Bug 1709787

This looks like broken gobject introspection. Switching components.

Switching components again, as python3-gobject3 is EPEL7, only.

Same problem from libmodulemd (linked the FTBFS bug).

Colin, could you please prioritize this? We plan to move Python 3.8 to a side tag in ~2 weeks. Packages that will fail to rebuild will block merging the side tag back to rawhide (~1 month from now) and may not be installable in Fedora 31.

The cause is - /usr/lib64/python3.8/site-packages/gi/_gi.cpython-38m-x86_64-linux-gnu.so has incorrect name:

<mock-chroot> sh-5.0# python3 -c 'from gi.repository import GLib'

<mock-chroot> sh-5.0# python3 -c 'from gi.repository import GLib'


Note that since 3.8.0a4, the "m" is not supposed to be there. Is it somehow hardcoded?

<mock-chroot> sh-5.0# python3-config --extension-suffix
.cpython-38-x86_64-linux-gnu.so

I don't see it hardcoded in spec, must be the build system, will examine.

Note: The Python 3 tests are skipped in %check. If they were not, the package would probably fail to build.

Examining the build log, this might simply require a bumped rebuild...

Yes, sorry about the noise.
