Code that embeds Python (rather than building an extension module) needs to pass `--embed` to any `python3-config --libs` invocation to build with Python 3.8. More information: https://docs.python.org/3.8/whatsnew/3.8.html#debug-build-uses-the-same-abi-as-release-build For the build logs, see: https://copr-be.cloud.fedoraproject.org/results/@python/python3.8/fedora-rawhide-x86_64/00992313-vdr-epg-daemon/ For all our attempts to build vdr-epg-daemon with Python 3.8, see: https://copr.fedorainfracloud.org/coprs/g/python/python3.8/package/vdr-epg-daemon/ Testing and mass rebuild of packages is happening in copr. You can follow these instructions to test locally in mock if your package builds with Python 3.8: https://copr.fedorainfracloud.org/coprs/g/python/python3.8/ Let us know here if you have any questions.
I solved the issue by changing the following lines in the vdr-epg-daemon.spec file. %if 0%{?fedora} <= 30 BuildRequires: python2-devel %else #BuildRequires: python3-devel BuildRequires: python38 %endif ... ## Add --embed flag for python 3.8 Support in 'Makefile' %if 0%{?fedora} >= 31 sed -i -e 's|python-config --libs|python3.8-config --libs --embed|' Makefile sed -i -e 's|python-config|python3.8-config|' Make.config %endif
%else #BuildRequires: python3-devel BuildRequires: python38 %endif Don't do this please. The package shall build against python3-devel. We will update python3-devel to 3.8 in Fedora in ~a week.
This bug appears to have been reported against 'rawhide' during the Fedora 31 development cycle. Changing version to '31'.
The coordinated rebuild of Python 3.8 has started in the `f32-python` side tag. If you figure out how to rebuild this package, please don't rebuild it in regular rawhide, but use the side tag instead: on branch master: $ fedpkg build --target=f32-python To wait for a build to show up in the side tag, do: $ koji wait-repo f32-python --build=<nvr> Where <nvr> is name-version-release of the source package, e.g. python-foo-1.1-2.fc32. An updated mock config is posted at: http://copr.fedorainfracloud.org/coprs/g/python/python3.8/ Note that it will take a while before the essential packages are rebuilt, so don't expect all your dependencies to be available right away. Thanks. Let us know if you need up to date info, or if you have any questions. PS this message is mass posted to all the bugs that block the PYTHON38 bug. If this is also a Fedora 31 FTBFS bug and you manage to fix it, you can do a f31 build as usual: on branch f31: $ fedpkg build
The f32-python side tag has been merged. In order to rebuild the package, do it in regular rawhide, but please wait until python3-3.8 is tagged: $ koji wait-repo f32-build --build python3-3.8.0~b3-3.fc32 If your built already started in f32-python, after it is finished, please tag it to rawhide with: $ koji tag-build f32-pending <nvr> For example: $ koji tag-build f32-pending libreoffice-6.3.0.4-3.fc32 Thanks! (This comment is mass posted to all bugzillas blocking the PYTHON38 tracking bug.)
(Python 3.8 has landed in the rawhide buildroot.)
successfully built for rawhide.
Thank You!
