"InitError: could not load library" during precompilation on Linux x86

[denglerchr]

I am having an error during precompilation on Linux x86 on two different PCs. versioninfo():

Julia Version 1.10.2
Commit bd47eca2c8* (2024-03-01 10:14 UTC)
Build Info:

    Note: This is an unofficial build, please report bugs to the project
    responsible for this build and not to the Julia project unless you can
    reproduce the issue using official builds available at https://julialang.org/downloads

Platform Info:
  OS: Linux (x86_64-pc-linux-gnu)

The error appears as soon as the package (v1.3.0) is added. What is weird, isfile(raw"/home/christiand/.julia/artifacts/d587f48a6815c72dec4b083bf297caec7a8e3f4b/lib/alsa-lib/libasound_module_pcm_a52.so") returns true...

the problem doesn't appear to be finding libasound_module_pcm_a52.so, it's that that library seems to be dependent on libavcodec.so.58, which it's not finding.

what version of alsa_jll, alsa_plugins_jll, libportaudio_jll, and FFMPEG_jll do you have installed? In particular, that libasound module is provided by alsa_plugins_jll, and the libavcodec should be provided by FFMPEG_jll.

It looks like the latest version of FFMPEG_jll builds libavcodec.so.60, so maybe alsa_plugins_jll needs to be updated to match.

I'm pretty out of touch with how the binary build system works these days, so it may be worth filing an issue on the Yggdrasil repo, they may have a better idea.

[denglerchr]

It happens on a completely new project with only PortAudio added. Attached also the Manifest.toml in a Zip.

• alsa_jll : version = "1.2.5+0"
• alsa_plugins_jll : version = "1.2.2+0"
• libportaudio_jll : version = "19.7.0+0"
• FFMPEG_jll : version = "6.1.1+0"

Under Windows, with the same versions of packages, PortAudio works well.

I have the same problem on Ubuntu 24.04.

There appears to be a number of libraries missing:

$ ldd /home/tp_test/.julia/artifacts/d587f48a6815c72dec4b083bf297caec7a8e3f4b/lib/alsa-lib/libasound_module_pcm_a52.so
	linux-vdso.so.1 (0x00007ffe53518000)
	libavcodec.so.58 => not found
	libavutil.so.56 => not found
	libavresample.so.4 => not found
	libasound.so.2 => /lib/x86_64-linux-gnu/libasound.so.2 (0x00007577d15de000)

	libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007577d14ee000)

	libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007577d0e00000)
	/lib64/ld-linux-x86-64.so.2 (0x00007577d1703000)

The versions installed on my system are:

/lib/x86_64-linux-gnu/libavcodec.so.60
/lib/x86_64-linux-gnu/libavutil.so.58
/lib/x86_64-linux-gnu/libswresample.so.4

(the last one is the closest I could find).

But I do not know how to fix it :-(

[tp2750]

I managed to build alsa_plugin locally by restricting the number of architectures and pinning FFMPEG to version 4.4: JuliaPackaging/Yggdrasil#8863

This is not enough to make PortAudio install, but if I explicitly use FFMPEG_jll@4.4.0 it works.

So I suppose if we go this route, we need to add a compat of FFMPEG_jll to restrict it to ~4.4.

However, on my host system (Ubuntu 20.24) I have a copy of libasound_module_pcm_a52.so that links to libavcodec.so.60, so there does not seem to be a reason we can not build alsa_plugin using the newer libraries.

[tp2750]

Oh, there is a new version of alsa-plugins: 1.2.7.1. That builds with the current version of FFMPEG.
I'll update my PR.

I just wanted to add that I also ran into this issue just now in a fresh environment under julia 10.4.

This is Julia 1.10.4 and clean Pkg.generate("mwe") environment with just PortAudio package.
Portaudio libraries on the system are

Looks like this Julia package is completely broken, are there any alternatives for Julia to read sound device ?

Thanks

I'm hoping PortAudio.jl can support PipeWire systems as well since that's a popular choice for the Linux audio server. It was suggested

to build Pipewire with binary builder and then make alsa-plugins aware of it:
