Cannot execute esp-clang/bin/clang since the dynamic loader or dynamic library is missing

[oddlama]

It looks like $IDF_PATH/esp-clang/bin/clang is not patchelf-ed or missing a dynamic lib that is missing in the build sandbox. I was only able to get it to work in devshells on systems that use nix-ld as otherwise the dynamic loader or one of the required libs is missing.

The esp-clang tool is required when compiling esp-idf-sys (the rust crate). I've made a minimal example to reproduce this by executing the binary in a sandboxed mkDerivation:

test.nix

let
  nixpkgs-esp-dev = builtins.fetchGit {
    url = "https://github.com/mirrexagon/nixpkgs-esp-dev.git";
    rev = "52a23afb15a1643a3dbeeb963097945a3f35b0fb";
  };

  pkgs = import <nixpkgs> { overlays = [ (import "${nixpkgs-esp-dev}/overlay.nix") ]; };
in
pkgs.stdenv.mkDerivation {
  pname = "esp-project";
  version = "1.0.0";

  buildInputs = [ pkgs.esp-idf-full ];

  dontUseCmakeConfigure = true;
  dontUseNinjaBuild = true;
  dontUseNinjaInstall = true;
  dontUseNinjaCheck = true;

  # Just an empty folder
  src = pkgs.writeTextDir "dummy" "";

  buildPhase = ''
    $IDF_PATH/esp-clang/bin/clang
  '';
}

output of nix-build test.nix

In case anyone is unfamiliar, the no such file or directory is unfortunately a super bad error message - it actually refers to one of the dynamic libraries or the loader itself not being found, not to the executable. Running ldd /nix/store/jxpii7sp9i6m9r3k1xxjq6v4kqzk576v-esp-idf-v5.5/esp-clang/bin/clang shows:

Not sure which one is missing in the build sandbox, this output is from my normal shell.
