Doesn't work with target x86_64-unknown-linux-musl

[deade1e]

Hello,

I tried to build a static version of my project by using the aforementioned Rust target and there is no way to make it compile, as it doesn't find asound library (static version).

I tried on ubuntu and then alpine linux (which uses musl by default). Nothing can be done.

I then was able to compile it on NixOS with this specific shell.nix:

{ pkgs ? import <nixpkgs> { } }:

pkgs.mkShell {
  buildInputs = with pkgs; [
    # static cross-compilation tools
    pkgsStatic.stdenv.cc

    # ALSA libraries for musl.. yes pkgsStatic often means musl
    pkgsStatic.alsa-lib
    pkgsStatic.alsa-lib.dev
    pkgsStatic.pkg-config
  ];

  shellHook = ''
    export PKG_CONFIG_ALLOW_CROSS=1
    export PKG_CONFIG_PATH="${pkgs.pkgsStatic.alsa-lib.dev}/lib/pkgconfig:$PKG_CONFIG_PATH"
    export CARGO_TARGET_X86_64_UNKNOWN_LINUX_MUSL_LINKER="${pkgs.pkgsStatic.stdenv.cc}/bin/x86_64-unknown-linux-musl-cc"
  '';
}

But then when running the application the following output is what I get:

note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

This happens when in my code I try to create the stream.

If the project is built using the -gnu target everything is fine.

The project using the library is the following: https://github.com/pfrankw/aemt

Thank you
