Package: src:python-libusb1 Version: 3.3.1+ds-4 Severity: serious Tags: ftbfs forky sid
Dear maintainer: During a rebuild of all packages in unstable, this package failed to build. Below you will find the last part of the build log (probably the most relevant part, but not necessarily). If required, the full build log is available here: https://people.debian.org/~sanvila/build-logs/202512/ About the archive rebuild: The build was made on virtual machines from AWS, using sbuild and a reduced chroot with only build-essential packages. If you cannot reproduce the bug please contact me privately, as I am willing to provide ssh access to a virtual machine where the bug is fully reproducible. If this is really a bug in one of the build-depends, please use reassign and add an affects on src:python-libusb1, so that this is still visible in the BTS web page for this package. Thanks. -------------------------------------------------------------------------------- [...] debian/rules clean dh clean --buildsystem=pybuild dh_auto_clean -O--buildsystem=pybuild I: pybuild base:317: python3.14 setup.py clean /usr/lib/python3/dist-packages/setuptools/dist.py:759: SetuptoolsDeprecationWarning: License classifiers are deprecated. !! ******************************************************************************** Please consider removing the following classifiers in favor of a SPDX license expression: License :: OSI Approved :: GNU Lesser General Public License v2 or later (LGPLv2+) See https://packaging.python.org/en/latest/guides/writing-pyproject-toml/#license for details. ******************************************************************************** [... snipped ...] expected_name = expected_name[:-2] # NOTE: on macOS with .framework bundle build, INSTSONAME contains full name of the .framework library, for example # `Python.framework/Versions/3.13/Python`.

Return full path to Python dynamic library or None when not found. PyInstaller needs to collect the Python shared library, so that bootloader can load it, import Python C API symbols, and use them to set up the embedded Python interpreter. The name of the shared library is typically fixed (`python3.X.dll` on Windows, libpython3.X.so on Unix systems, and `libpython3.X.dylib` on macOS for shared library builds and `Python.framework/Python` for framework build). Its location can usually be inferred from the Python interpreter executable, when the latter is dynamically linked against the shared library. However, some situations require extra handling due to various quirks; for example, Debian-based linux distributions statically link the Python interpreter executable against the Python library, while also providing a shared library variant for external users.
