Description Marcel Plch 2020-02-21 12:16:04 UTC 
csound fails to build with Python 3.9.0a3.

I have not been able to determine from the logs, what exactly is happening here, my guess is it might not even be Python related.

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
PORTTIME_LIBRARY
    linked by target "pmidi" in directory /builddir/build/BUILD/csound-6.14.0/InOut
-- Generating done
CMake Warning:
  Manually-specified variables were not used by the project:
    BUILD_CSOUND_AC
    BUILD_CSOUND_AC_PYTHON_INTERFACE
    CMAKE_Fortran_FLAGS_RELEASE
    LIB_INSTALL_DIR
    LIB_SUFFIX
    SHARE_INSTALL_PREFIX
    SWIG_ADD_LIBRARY
    SYSCONF_INSTALL_DIR
CMake Generate step failed.  Build files cannot be regenerated correctly.

For the build logs, see:
https://copr-be.cloud.fedoraproject.org/results/@python/python3.9/fedora-rawhide-x86_64/01245923-csound/

For all our attempts to build csound with Python 3.9, see:
https://copr.fedorainfracloud.org/coprs/g/python/python3.9/package/csound/

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 3.9:
https://copr.fedorainfracloud.org/coprs/g/python/python3.9/

Let us know here if you have any questions.

Python 3.9 will be included in Fedora 33. To make that update smoother, we're building Fedora packages with early pre-releases of Python 3.9.
A build failure prevents us from testing all dependent packages (transitive [Build]Requires), so if this package is required a lot, it's important for us to get it fixed soon.
We'd appreciate help from the people who know this package best, but if you don't want to work on this now, let us know so we can try to work around it on our side.
Comment 1 Miro Hrončok 2020-05-25 13:02:09 UTC 
This comment is mass posted to all bugs blocking the Python 3.9 tracker, sorry if it is not 100 % relevant. When in doubt, please ask.


The Python 3.9 rebuild is in progress in a Koji side tag.

If you fix this bug, please don't rebuild the package in regular rawhide, but do it in the side tag with:

    $ fedpkg build --target=f33-python

The rebuild is progressing slowly and it is possible this package won't have all the required build dependencies yet. If that's the case, please just leave the fix committed and pushed and we will eventually rebuild it for you.

You are not asked to go and try rebuild all the missing dependencies yourself. If you know there is a bootstrap loop in the dependencies, let me know and we can untangle it together.

If you want to test your fix or reproduce the failure, you can still use the Copr repo mentioned in the initial comment of this bug: https://copr.fedorainfracloud.org/coprs/g/python/python3.9/
Comment 2 Miro Hrončok 2020-05-29 07:11:59 UTC 
Python 3.9 update: The f33-python side tag is currently being merged.

New builds in f33-python are no longer possible, but python3 is not yet updated to Python 3.9 in rawhide. You can check when Python is Python 3.9 with:

    $ koji wait-repo f33-build --build python3.9-3.9.0~b1-3.fc3

And build the packages normally after that.

This bug appears to have been reported against 'rawhide' during the Fedora 33 development cycle.
Changing version to 33.
Comment 5 Miro Hrončok 2020-08-22 10:30:42 UTC 
Hello. This comment is mass posted to all 16 bugzillas for packages that failed to rebuild with Python 3.9 (and, in most cases, also fail to install on Fedora 33 and 34). Apologies if some of the suggestions or questions don't apply 100%.

Fedora 33 Beta Freeze starts next week on Tuesday, 2020-08-25. I haven't spammed this bugzilla because it is in ASSIGNED, or I've seen upstream has been notified.

Please consider what to do here. Is this failure critical? For example, can a test be temporarily skipped to make this package build? Is it possible to fix or workaround the failure before Fedora 33 Beta? Or before Fedora 33 Final? If not, would it make sense to retire the package (even temporarily) before the release to unblock updates from Fedora 31 or Fedora 32?

In case you need any assistance with a Python-related problem with the build, don't hesitate to let me know and I'll try to have a look.

Thank you!

The main issue in this bug was caused by the cmake change.
