Hi!

ctypes.util.find_library can't find the lib on Alpine. I think this is because the logic is not cover the digital suffixes.

Docker example:

docker run --rm -it python:3.9-alpine sh

apk add libuuid build-base

ls /lib/libuuid*
# /lib/libuuid.so.1
# /lib/libuuid.so.1.3.0

python -c 'from ctypes.util import find_library; print(find_library("uuid"))'
# None


## Workaround:

cd /lib && ln -s libuuid.so.1 libuuid.so

python -c 'from ctypes.util import find_library; print(find_library("uuid"))'
# libuuid.so.1

Thanks!

Alpine/musl is unsupported per PEP-11. (It would be nice to support it, but, people interested in doing the work somehow don't show up around this repo.)

I'll close the bug. Like other issues for unsupported platforms, it'll be listed on the GitHub project for anyone who wants to support the platform unofficially or work to make it officially supported.
I encourage such people to add themselves to the Experts list so we know whom to ping.
