Question: packaging a platformio project that doesn't use a Makefile

[crabdancing]

So far, I've figured out that to use platformio2nix, I have to manually write my own buildPhase/patchPhase/etc. As it stands, if I try to call pio run -t build, like so:

{
  gnumake,
  makePlatformIOSetupHook,
  platformio,
  stdenv,
  which,
}: let
  setupHook = makePlatformIOSetupHook {
    lockfile = ./platformio2nix.lock;
  };
in
  stdenv.mkDerivation {
    name = "my-project";
    version = "0.0.0";
    src = ./.;
    nativeBuildInputs = [platformio setupHook];

    buildPhase = ''
      pio run -t build
    '';
  }

The result is that PlatformIO immediately tries to connect to the internet, fails, and throws a fit:

       > --------------------------------------------------------------------------------
       > Library Manager: Installing askuric/Simple FOC @ ^2.3.4
       > InternetConnectionError: You are not connected to the Internet.
       > PlatformIO needs the Internet connection to download dependent packages or to work with PlatformIO Account.
       For full logs, run 'nix log /nix/store/q0mhvwcjlhzhnai56alwzhwcx3qwldhw-my-project.drv'.

So there's something special I have to do to get the dependencies fetched by Nix via platformio2nix to be used by pio?

Hmm, you shouldn't have to do anything special. The setupHook will set the PLATFORMIO_CORE_DIR environment variable to a path in the build dir, which should take care of things. My guess is the dependency isn't in the lockfile or there's a bug linking dependencies in setupHook. Do you have an example repo?
