Can't find portaudio in alpine docker container #467

Open FX-Wood opened 1 year ago

FX-Wood commented 1 year ago

I was having trouble locating the portaudio library inside an alpine docker container. It appears that this is because ctypes.util.find_library has trouble finding libraries in some cases. The workaround is to make a symlink to the library without the digit:

apk add portaudio cd /usr/lib && ln -s [library.name.[0-9]] [library.name] I found this solution here: https://bugs.python.org/issue43642

It looks like maybe this issue on the cpython repo has some further discussion: from: https://github.com/python/cpython/pull/18380

Leaving this issue here for anyone else who is looking for a workaround.
