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.

"""
Find Python shared library that belongs to the current interpreter.
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.
