vesktop: "your c++ library is too old to run venmic"

[jemand771]

Describe the bug

Trying to screenshare in vesktop reports the following problem/warning:

Failed to retrieve Audio Sources because your C++ library is too old to run venmic.
See this guide for possible solutions

Steps To Reproduce

Steps to reproduce the behavior:

1. Install vesktop (from unstable in my case)
2. Join any voice channel
3. Open the screenshare dialog

Expected behavior

A list of audio sources (applications) should be displayed

Screenshots

screenshare dialog

Additional context

I initially ran into #306374 (pr: #306421) which prompted me to switch to unstable in the first place. My system is still on 23.11, but I pull vesktop from nixpkgs-unstable.
I'm new to nix+nixos (hi!) but as far as I can understand, this should still work.

Unlike the linked issue's reporter, I'm on x11 which I assume is why it's working for them but not me.

I think there isn't much we can do here for 23.11. Perhaps wait for 24.05 or pull in vesktop from unstable

[jemand771]

I am pulling from unstable D:

[Scrumplex]

Oh, yeah, I just realized after re-reading the issue. I wonder if there is some more helpful log output for you. It seems to work fine for me, though I am on Sway

[jemand771]

right, I could have run vesktop in a terminal to get the actual output. forgot to include that, whoops

[willy@nixbox:~]$ vesktop

Could you tell me what's the exact revision of Nixpkgs you are using for Vesktop? Current nixos-unstable produces a slightly different output

[jemand771]

from my flake.lock

this should be from "a couple of days ago™️", not sure exactly when

for completeness, here's how I defined them (this should be correct):

  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-23.11";
    nixpkgs-unstable.url = "github:NixOS/nixpkgs/nixos-unstable";
  };

[Scrumplex]

I think this is an incarnation of #84043. Not sure if we can do much about it :/

[jemand771]

I've looked over the issue you linked, but I don't really understand the problem

what does this mean for me? will this magically fix itself eventually (e.g. when 24.05. comes out)? why is this only broken for some people/just me, but not others? (I assume others would have reported it already)

[Scrumplex]

The issue seems to be the glibc that is shipped by NixOS 23.11. I am not 100% sure why this issue is present, because I would expect venmic to inherit the glibc that's used to launch Vesktop in the first place (which should be one from unstable).

If you were to move your system to unstable (or 24.05 soon) it should be fixed.

[jemand771]

alright, that's fine by me. I think I can wait the 3-ish weeks :b

thanks a ton for your patience and super quick replies! ✨

we can close this ticket as "will fix itself" or leave it open until 24.05 is out - you pick
