I had some trouble building on my nix machine as well. But as I needed to create a docker build file anyways I just used that.

I plan on switching to nix on my main computer soon. I can have a look at this then.

If you are willing to try and investigate/fix I would welcome any contributions.

My nix env is , (if this matters).

Seems like you had a link to some generic google page (ai workspace?) there. I removed it just in case.

[asukaminato0721]

oh, I should clarify it.. https://developers.google.com/idx/guides/devnix-reference , I don't know whether this env is special or not.

@asukaminato0721 i know its late, but just for completeness sake:

I switched to nix on my main machine this weekend and have a rough flake that works for me.

Will add it to the repo once its done.

{
  description = "ext-php-rs dev";

  inputs = {
    nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable";
    rust-overlay = {
      url = "github:oxalica/rust-overlay";
      inputs = {
        nixpkgs.follows = "nixpkgs";
      };
    };
  };

  outputs =
    { nixpkgs, rust-overlay, ... }:
    let
      system = "x86_64-linux";
      overlays = [ (import rust-overlay) ];
      pkgs = import nixpkgs { inherit system overlays; };
      php-dev = pkgs.php.unwrapped.dev;
    in
    {
      devShells.${system} = {
        default = pkgs.mkShell {
          buildInputs = with pkgs; [
            php
            php-dev
            libclang.lib
            clang
          ];

          nativeBuildInputs = [ pkgs.rust-bin.stable.latest.default ];

          shellHook = ''
            export LIBCLANG_PATH="${pkgs.libclang.lib}/lib"
          '';
        };
      };
    };
}

For me it was actually just the clang package that fixed the message you had. Guess that is something special to your environment.
