I have not forgotten about your post. The day job is just in the way at the moment; preventing additionally testing.

@michaelwa can you check whether functions from the :crypto module work for you? If so, we probably fail to find OpenSSL. If not, it’s indeed missing, but we probably can emit a better error. Anyway, installing OpenSSL may indeed help :wink:

I think the root of the problem is my OS version. It is an Ubuntu 20.04 derivative (Pop_OS! 20.04). I do have openssl installed but it is version 1.1.1. ❯ openssl version OpenSSL 1.1.1f 31 Mar 2020 The missing file, libssl.so.3, is part of the openssl3-dev package and does not seem to be compa…

As a workaround, you can opt out of precompiled PortAudio by putting this into config.exs: config :bundlex, :disable_precompiled_os_deps, apps: [:membrane_portaudio_plugin] and installing PortAudio manually with sudo apt-get install alsa portaudio19-dev I suppose it could work with Openssl 1.1 t…

Ok, so it seems possible to make it work with OpenSSL 1.1, however, Ubuntu 20.04 uses an old version of GlibC as well, which is harder to support. Thus, it seems that until you upgrade the OS, you need to disable the precompiled deps completely: config :bundlex, :disable_precompiled_os_deps, true ^…
