Cannot compile gleam_stdlib when using mix_gleam

[mradke]

I’m currently trying to test gleam inside of a mix project. I followed the GitHub - gleam-lang/mix_gleam: ⚗️ Build Gleam code with mix readme but when I try to compile I’ll get the following error:

Could not compile :gleam_stdlib, no "mix.exs", "rebar.config" or "Makefile" (pass :compile as an option to customize compilation, set it to "false" to do nothing)

The configuration in mix.exs looks like this:

...
  @app :gleam_exp

  def project do
    [
      app: @app,
      version: "0.1.0",
      elixir: "~> 1.14",
      elixirc_paths: elixirc_paths(Mix.env()),
      start_permanent: Mix.env() == :prod,
      aliases: aliases(),

      # Gleam config
      archives: [mix_gleam: "~> 0.6"],
      compilers: [:gleam | Mix.compilers()],
      aliases: [
        # Or add this to your aliases function
        "deps.get": ["deps.get", "gleam.deps.get"]
      ],
      erlc_paths: [
        "build/dev/erlang/#{@app}/_gleam_artefacts",
        # For Gleam < v0.25.0
        "build/dev/erlang/#{@app}/build"
      ],
      erlc_include_path: "build/dev/erlang/#{@app}/include",
      # For Elixir >= v1.15.0
      prune_code_paths: false,

      deps: deps(),
    ]
  end
...

Elixir version: 1.16.3 (compiled with Erlang/OTP 25)
Gleam version: 1.3.2

Any pointers why this is happening?

And you added gleam_stdlib to the mix deps?

# in mix.exs
# ...
  defp deps do
    [
      # ...
      {:gleam_stdlib, "~> 0.34 or ~> 1.0"},
      {:gleeunit, "~> 1.0", only: [:dev, :test], runtime: false},
      # ...
    ]
  end
# ...

Thanks for the answer! Yes. I followed the guide and added the deps. They are also in the deps folder locally but they are indeed missing the "mix.exs", "rebar.config" or "Makefile" files.

And what about the example project? https://github.com/gleam-lang/mix_gleam/tree/main/test_projects/basic_project

I just checked that one and mix test runs fine on my machine (OTP 27 + Elxir 1.17) (after running mix deps.get).
