Description Tomáš Hrnčiar 2021-12-20 14:21:55 UTC

rmol fails to build with Python 3.11.0a3.

-- Requires Python with version 3.4; however just Python3 is considered here
CMake Error at config/FindPackageHandleStandardArgs.cmake:230 (message):
  Could NOT find Python3 (missing: Python3_LIBRARIES Python3_INCLUDE_DIRS
  Development)

I think, the problem is that somewhere in CMake is missing support for Python 3.11. I proposed patch to CMake to add it, but it seems like it's not enough for rmol.

For the build logs, see:
https://copr-be.cloud.fedoraproject.org/results/@python/python3.11/fedora-rawhide-x86_64/03059875-rmol/

For all our attempts to build rmol with Python 3.11, see:
https://copr.fedorainfracloud.org/coprs/g/python/python3.11/package/rmol/

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 3.11:
https://copr.fedorainfracloud.org/coprs/g/python/python3.11/

Let us know here if you have any questions.

Python 3.11 is planned to be included in Fedora 37. To make that update smoother, we're building Fedora packages with all pre-releases of Python 3.11.
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.

This bug appears to have been reported against 'rawhide' during the Fedora 36 development cycle.
Changing version to 36.

Comment 3 Denis Arnaud 2022-06-20 11:30:49 UTC

We will need a special version of Boost with parallel sub-packages for Python 3.10 and Python 3.11. Do you know whether the Boost package will provide those Python sub-packages?

> We will need a special version of Boost with parallel sub-packages for Python 3.10 and Python 3.11. 

Why? Boost is only available for 3.11, which is the only Python version rmol should use now.

Ok, my bad then, sorry for the confusion!

I will work on it when I have more time (a weekend in the next few weeks). I have 2 other packages (trademgen/BZ#2099179, opentrep/BZ#2034561) having a similar issue.

Thanks!

Hello,

Please note that this comment was generated automatically. If you feel that this output has mistakes, please contact me via email (mhroncok).

All subpackages of a package against which this bug was filled are now installable or removed from Fedora 37.

Thanks for taking care of it!
