@Pacman99 Thanks for your work so far.
This certainly seems like a hard thing to package.

Pacman99's current attempt results (at least on my machine) in the binary just checking for this file thousands of times then eventually giving up and stopping:

I guess it segfaulted due to infinite recursion (which is probably just retry logic when the startup fails).

The libspark file included in the deb, and the nix expression does seem to set up LD_LIBRARY_PATH to point to a directory which includes it:

(gdb) show environment LD_LIBRARY_PATH
LD_LIBRARY_PATH = /nix/store/wvj22k2c8bs3prfbgapij2aykmvm008f-webex-41.5.0.18815/opt/Webex/lib

$ ls -al /nix/store/wvj22k2c8bs3prfbgapij2aykmvm008f-webex-41.5.0.18815/opt/Webex/lib/libspark-windows-desktop-ui.so
-r--r--r-- 1 root root 179808592 Dec 31  1969 /nix/store/wvj22k2c8bs3prfbgapij2aykmvm008f-webex-41.5.0.18815/opt/Webex/lib/libspark-windows-desktop-ui.so

It's unclear to me why dlopen is only checking /nix/store/0c7c96gikmzv87i7lv3vq5s1cmfjd6zf-glibc-2.31-74/lib/libspark-windows-desktop-ui.so and not /nix/store/wvj22k2c8bs3prfbgapij2aykmvm008f-webex-41.5.0.18815/opt/Webex/lib/libspark-windows-desktop-ui.so even though LD_LIBRARY_PATH is set correctly.

djahandarie · 2021-05-15T18:15:15Z

Update: it seems like CiscoCollabHost forks and execs itself without the LD_LIBRARY_PATH environment variable. So the solution seems to be to use wrapProgram on CiscoCollabHost so it gets set again, as opposed to the makeWrapper method you were using.

    wrapProgram $out/opt/Webex/bin/CiscoCollabHost \
      --prefix LD_LIBRARY_PATH : $out/opt/Webex/lib

    ln -s $out/opt/Webex/bin/CiscoCollabHost $out/bin/webex

@Pacman99

Pacman99 · 2021-05-15T18:21:46Z

Ohh wow thank you for debugging and figuring that out! I'll update the PR.

djahandarie · 2021-05-15T18:23:31Z

You're welcome! With that the app starts and seemingly works, but audio is beyond messed up (shockingly loud amounts of pure static) 😆.

Not sure why, it seems to successfully create a "WebexAudioPlayback" device in pulse, but I guess some audio codec or sample rate or something gets messed up...

Pacman99 · 2021-05-15T18:27:00Z

Yeah I get a problem that it can't connect to the server.

I wonder if we need to wrap all the binaries, is there any nixpkgs script or hook for that?

Or maybe to play it safe a fhsenv would be the best solution.

djahandarie · 2021-05-15T18:57:59Z

FWIW the app actually works perfectly fine for me (can join video calls and everything), it just has the audio issue -- using my corporate webex account

skogsbrus · 2021-07-19T14:51:34Z

Completely new to Nix, but am interested in this as well!

I haven't tried it at my day job, but the app has worked well in my limited testing. ~~The audio device names look very unfamiliar, but they do map correctly to my mic and speaker.~~ [ edit: seems like these unfamiliar names relate to nixos in general rather than webex ]

Had to change the version and shasum since the package has been updated though. It seems they don't publish versioned urls.

  src = fetchurl {
    url = "https://binaries.webex.com/WebexDesktop-Ubuntu-Official-Package/Webex.deb";
    sha256 = "5b15f4f71024685baa3675e2e1f33d0572cb75943b618ccf67673b04c70904cc";
  };

Ran it like so first:
nix-build -E 'with import <nixpkgs> {}; callPackage ./webex.nix
./result/bin/webex

Then installed it with home-manager:

  home-manager.users.skogsbrus = { pkgs, ... }: {
    home.packages = [
      (pkgs.callPackage ./webex.nix {})
    ];
  };

buckley310 · 2021-07-19T15:46:15Z

#122796 also seems to run for me and I can get signed in with it and stuff. I'm going to try using it for a little while and see how it works

skogsbrus · 2021-08-17T07:16:07Z

With #122796, audio is good for me, but it seems you can't share your screen - maybe they hadn't introduced that feature in 41.5?

The latest version doesn't work for me - the installation completes but running the binary doesn't do anything.

EDIT:

So it seems that the "share your screen" button does not appear because I'm running on Wayland, which they apparently don't support.

EDIT 2: the binary starts up correctly sometimes, and sometimes exits without doing anything. Relaunching it until it starts has worked ok though

djahandarie · 2021-10-19T20:12:30Z

I wonder if the audio issue I experience has to do with my soundcard being 48k as opposed to 44.1k and something in webex doesn't like that... it might be specific to my setup and not this packaging.
