PortAudio on Pi Zero W

[thomarse-ef]

Hi. I thought I'd open this as an issue. This seems to be the same issue as this one, I've been trying but can't apply it to fix my issue.

I'm trying to use the PortAudio package, I get this error:

In the solution here it seems to be straightforward to copy the files to the correct place but I can't find the correct files in /usr/lib/arm-linux-gnueabihf and I'm not sure exactly where to copy them to. Also for the second and third errors it's not clear which files need to be copied. Any advice would be much appreciated.

Hello @thomarse-ef. I'm sorry to late reply for you.

As for PortAudio.jl, it depends on alsa_plugins_jll and libportaudio_jll according to
https://github.com/JuliaAudio/PortAudio.jl/blob/master/Project.toml#L7-L8

where foo_jll is a JLL pakages (a pun on Dynamic-Link Library).
Julia manages dependencies which are created by e.g. C/C++/Fortran library on Yggdrasil.

For example, alsa_plugins_jll is created via https://github.com/JuliaPackaging/Yggdrasil/blob/master/A/alsa_plugins/build_tarballs.jl
. When one tries to use PortAudio, it will call alsa_plugins_jll and this JLL tries to load shared libraries such as

https://github.com/JuliaPackaging/Yggdrasil/blob/master/A/alsa_plugins/build_tarballs.jl#L28-L43

Therefore, this is an answer regarding alsa_plugins_jll.
