[Bug] Crash due to dynamically linked libraries in Appimage

While using appimage-run on NixOs, the app crashes with

Uncompress Buzz_0.4.23_amd64.AppImage of type 02 @ offset 944632
[===========================================================================================================================================|] 3465/3465 100%
Buzz_0.4.23_amd64.AppImage is now installed in /home/i/.cache/appimage-run/679f0bfb1eb5287c15abc0da386d7b877a6f8302f020a80f239598e102564327
buzz-desktop: error while loading shared libraries: libzstd.so.1: cannot open shared object file: No such file or directory

Steps to reproduce the behavior:

Run on NixOs or in Nix shell
Launch appimage-run Buzz_0.4.23_amd64.AppImage
App crashes

Expected behavior:

Running as other binaries.

Environment (please complete the following information):

OS: Linux NixOs
26.05

I also tried the appimage on NixOS.
I can get beyond these errors by adding some extra libs for appimage-run:

  programs.appimage.enable = true;
  programs.appimage.binfmt = true;
  programs.appimage.package = pkgs.appimage-run.override {
    extraPkgs = pkgs: [
      pkgs.zstd
      # libelf.so.1 (needed transitively via appimage-run's Mesa/LLVM GL stack).
      # NB: pkgs.libelf ships only a static libelf.a — the shared lib comes from
      # elfutils, whose `out` output buildFHSEnv pulls in automatically.
      pkgs.elfutils
    ];
  };

but then webkit still crashes and i only see a transparent window.

what works for me is re-packaging the debian package:

# Buzz desktop (https://github.com/block/buzz) — a Tauri/WebKitGTK app.

@tw-360vier thanks for sharing this.

I've tried to build Appimage myself and ended up with only working option when using Docker image for build. This allowed me to launch app but i did see same transparent window. I will try to re-use your script, ty.

Fixed in #2713 — AppImage keeps bundled libzstd.

Same issue with libelf:

➜ appimage-run ./Buzz_0.5.2_amd64.AppImage
Uncompress Buzz_0.5.2_amd64.AppImage of type 02 @ offset 944632
[===========================================================================================================|] 3406/3406 100%
Buzz_0.5.2_amd64.AppImage is now installed in /home/steven/.cache/appimage-run/68c1048346720d7d3c398ccb701e9df1eebdcd1acd7ea0b25a5d42e956428b87
buzz-desktop: error while loading shared libraries: libelf.so.1: cannot open shared object file: No such file or directory

There are bunch of libraries which are getting removed for packaging Appimage.
For Nixos "installing" DEB works.

I briefly looked into what agent did to fix this and i think it didn't.

COS-745: Add evidence-backed Delivery Room (#15)

I manage to make it work with this in my nix config (sorry for the formatting)

programs.appimage.enable = true;
programs.appimage.binfmt = true;
programs.appimage.package = pkgs.appimage-run.override {
extraPkgs = pkgs: with pkgs; [
elfutils
zstd
gst_all_1.gstreamer
gst_all_1.gst-plugins-base
gst_all_1.gst-plugins-good
gst_all_1.gst-plugins-bad
gst_all_1.gst-plugins-ugly
];
# Some AppImages (e.g. linuxdeploy-based ones bundling WebKitGTK) clear
# GST_PLUGIN_SYSTEM_PATH_1_0 at startup to avoid loading a possibly
# ABI-incompatible host GStreamer. GST_PLUGIN_PATH_1_0 is a separate,
# untouched variable that GStreamer scans just the same.
buildFHSEnv =
args:
pkgs.buildFHSEnv (
args
// {
profile = (args.profile or "") + ''
export GST_PLUGIN_PATH_1_0="/usr/lib/gstreamer-1.0:/usr/lib32/gstreamer-1.0''${GST_PLUGIN_PATH_1_0:+:$GST_PLUGIN_PATH_1_0}"
'';
}
);
};

One more Arch/Hyprland datapoint for the 0.5.3 AppImage: it opened an empty window while WebKitWebProcess repeatedly aborted. Running it from a terminal showed:

GStreamer element autoaudiosink not found. Please install it

Installing gst-plugins-good fixed the crash and the UI loaded. The next run reported a missing MPEG-4 AAC decoder; installing gst-libav fixed that too. I also cleared ~/.cache/gstreamer-1.0/registry.x86_64.bin before the successful launch.

--safe-rendering did not change the original failure. This may be worth noting in the AppImage runtime requirements if those plugins are intentionally supplied by the host.

feat(packages): add buzz-desktop from upstream .deb (0.5.8)
