Description Petr Viktorin 2019-06-07 14:49:49 UTC 
znc fails to build with Python 3.8.0b1.

The build cannot find Python API, Py_Initialize, because linker flags no longer contain libpython.
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_64/00927094-znc/

For all our attempts to build znc with Python 3.8, see:
https://copr.fedorainfracloud.org/coprs/g/python/python3.8/package/znc/

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:

Let us know here if you have any questions.

Nick?
Comment 2 Nicholas E. Bebout 2019-07-15 20:03:58 UTC 
I'll try to look at it this week, or if someone would like to send a patch that would be awesome.
Comment 3 Filipe Rosset 2019-07-21 02:24:47 UTC 
Opened upstream issue https://github.com/znc/znc/issues/1675
Comment 4 Nicholas E. Bebout 2019-07-24 15:46:17 UTC 
Looks like it will be fixed with the next release of ZNC.

> Looks like it will be fixed with the next release of ZNC.

I'm not sure, yesterday I downloaded the patch and tried to build 1.7.4 against py3.8 from Koji, no luck :(
Comment 6 Ben Cotton 2019-08-13 16:47:01 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora 31 development cycle.
Changing version to '31'.
Comment 7 Miro Hrončok 2019-08-14 22:24:07 UTC 
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
Comment 8 Miro Hrončok 2019-08-21 16:34:22 UTC 
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!

Comment 9 Miro Hrončok 2019-08-21 17:28:58 UTC 
(Python 3.8 has landed in the rawhide buildroot.)
Comment 10 Miro Hrončok 2019-09-16 08:41:11 UTC 
This issue is blocking the Python 3.8 rebuilds. If this package won't build with 3.8, it won't be installable, along with all its dependent packages, in Fedora 32.
Furthermore, as it fails to install, its dependent packages will fail to install and/or build as well.

Could you please look into this?
Comment 11 Nick Bebout 2019-09-23 13:39:11 UTC 
This is fixed in 1.7.5-rc1 which I am currently building for rawhide
