Description Karolina Surma 2025-03-31 09:37:51 UTC

kicad fails to build with Python 3.14.0a6.

-- Python module install path: /usr/lib64/python3.14/site-packages
CMake Error at /usr/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:227 (message):
  Could NOT find PythonLibs (missing: PYTHON_LIBRARIES PYTHON_INCLUDE_DIRS)
  (Required is at least version "3.6")
Call Stack (most recent call first):
  /usr/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:591 (_FPHSA_FAILURE_MESSAGE)
  cmake/FindPythonLibs.cmake:261 (find_package_handle_standard_args)
  CMakeLists.txt:982 (find_package)

For the build logs, see:
https://copr-be.cloud.fedoraproject.org/results/@python/python3.14/fedora-rawhide-x86_64/08837231-kicad/

For all our attempts to build kicad with Python 3.14, see:
https://copr.fedorainfracloud.org/coprs/g/python/python3.14/package/kicad/

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 3.14:
https://copr.fedorainfracloud.org/coprs/g/python/python3.14/

Let us know here if you have any questions.

Python 3.14 is planned to be included in Fedora 43.
To make that update smoother, we're building Fedora packages with all pre-releases of Python 3.14.
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 2025-03-31 09:57:01 UTC

kicad-9.0.1/cmake/FindPythonLibs.cmake has:

  set(_PYTHON3_VERSIONS 3.13 3.12 3.11 3.10 3.9 3.8 3.7 3.6 3.5 3.4 3.3 3.2 3.1 3.0)

The list needs to be updated to contain 3.14.

Comment 2 Steven A. Falco 2025-03-31 15:40:43 UTC

Change committed.  I am able to build locally against the python 3.14 copr.
