vtk fails to build with Python 3.8.0b1. The problem is: /builddir/build/BUILD/VTK-8.2.0/Wrapping/PythonCore/PyVTKMethodDescriptor.cxx:230:1: error: cannot convert 'std::nullptr_t' to 'Py_ssize_t' {aka 'long int'} in initialization For the build logs, see: https://copr-be.cloud.fedoraproject.org/results/@python/python3.8/fedora-rawhide-x86_64/00928698-vtk/ For all our attempts to build vtk with Python 3.8, see: https://copr.fedorainfracloud.org/coprs/g/python/python3.8/package/vtk/ 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.
In Python 3.8, the reserved "tp_print" slot was changed from a function pointer to a number, `Py_ssize_t tp_vectorcall_offset`. In C, there is no "nullptr"; either a 0 or NULL casts automatically to both pointers and numbers. Please use 0 instead of "nullptr" in the slot to be source-compatible both with Python 3.8 and previous versions. See this as an example PR: https://github.com/YafaRay/Core/pull/114
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.)
