[Feature]: Alter dynamic linking to be more portable

[rob-mur]

Is your feature request related to a problem? Please describe.
Currently on nixos backlog.md doesn't work without writing a derivation to wrap it due to hardcoded dynamic library paths in the bundled executable (such as libc).

I would prefer to be able to just install via npm and have the library work without this derivation (whilst I can package it to nixpkgs it makes versioning harder).

Describe the solution you'd like
Some ideas as it looks like you aren't the one hardcoding the paths but bun is when you do bun --compile:

• in cli.js, if the spawn fails due to missing interpreter, fallback to the users bun or node installation
• don't compile at all if not necessary? I'm unsure what the performance constraints are so may not be possible
• use musl/statically linked compilation

Additional context
Here for reference is a nix derivation that seems to work at least for me

Derivation for backlog.md CLI (https://github.com/MrLesk/backlog.md)

backlog.md ships a pre-built native binary per platform via npm optional

dependencies. This derivation fetches the linux-x64 binary tarball directly

from the npm registry and patches it with autoPatchelfHook so it works on

NixOS.

{ pkgs ? import {} }:

pkgs.stdenv.mkDerivation rec {
pname = "backlog-md";
version = "1.44.0";

src = pkgs.fetchurl {
url = "https://registry.npmjs.org/backlog.md-linux-x64/-/backlog.md-linux-x64-${version}.tgz";
sha256 = "1zc2kfzpw5m80gjnjnp8x9hpqxrldghls1p8a64hiana9j7b45zy";
};

nativeBuildInputs = [ pkgs.autoPatchelfHook ];
buildInputs = [ pkgs.glibc pkgs.gcc-unwrapped.lib pkgs.zlib ];

The tarball unpacks to ./package/

sourceRoot = "package";

dontBuild = true;
dontConfigure = true;

CRITICAL: Bun-compiled binaries append a zip payload containing the application code

to the end of the executable. The default Nix strip phase will remove this payload,

breaking the application and causing it to fall back to the default Bun REPL.

dontStrip = true;
