We are trying to python-setuptools_scm to version 10.x https://src.fedoraproject.org/rpms/python-setuptools_scm/pull-request/39 This package fails to build with: error: Installed (but unpackaged) file(s) found: /usr/lib64/python3.14/site-packages/src/ujson/python/version.h https://copr.fedorainfracloud.org/coprs/churchyard/vcs-versioning/package/python-ujson/ See https://setuptools-scm.readthedocs.io/en/latest/changelog/#1000-2026-02-26 """ Version files (write_to and version_file) are now written to the build directory during build_py instead of the source tree during version inference. This enables installing packages from read-only source directories (e.g., Bazel builds). Path transformation is automatically applied for src/ layouts - a configured path like src/mypackage/_version.py is correctly written to mypackage/_version.py in the build directory based on the package_dir configuration. To restore the old behavior of writing version files at inference time (useful for development workflows), set the environment variable SETUPTOOLS_SCM_WRITE_TO_SOURCE=1. https://github.com/pypa/setuptools-scm/issues/1252 """
Do you need help fixing this? Please respond.
I haven’t heard from Kushal in a long time. For about four years, I have been somewhat reluctantly keeping this package up to date as co-maintainer, since a few things I care about do depend on it. It doesn’t seem like exporting SETUPTOOLS_SCM_WRITE_TO_SOURCE=1 (in any or all spec-file sections) prevents the creation of /usr/lib64/python3.14/site-packages/src/ujson/python/version.h. I don’t really understand what’s happening at a glance, and I don’t want to spend much time on this package, so I suppose I will just remove the unwanted %{python3_sitearch}/src/ directory in %install as a workaround.
FEDORA-2026-1d2de06bc1 (python-ujson-5.12.0-2.fc45) has been submitted as an update to Fedora 45. https://bodhi.fedoraproject.org/updates/FEDORA-2026-1d2de06bc1
I heard from Kushal in person, but not wrt his Fedora packages :/ Thanks for the workaround.
FEDORA-2026-1d2de06bc1 (python-ujson-5.12.0-2.fc45) has been pushed to the Fedora 45 stable repository. If problem still persists, please make note of it in this bug report.
