The GraphX template submodule is defined in .gitmodules, but isn't used

[myclevorname]

I am making a Nix flake for this repo, shown below. When running nix flake lock, Nix complains that '«unknown»/examples/graphx/template' does not exist. Looking at the source tree, the folder examples/graphx/template does not exist or refer to anything.

{
  description = "Toolchain and libraries for C/C++ programming on the TI-84+ CE calculator series";

  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
    llvm-ez80.url = "github:myclevorname/llvm-ez80";
    toolchain = {
      flake = false;
      type = "git";
      submodules = true;
      url = "https://github.com/CE-Programming/toolchain";
    };
    flake-utils.url = "github:numtide/flake-utils";
  };

  outputs = { self, nixpkgs, llvm-ez80, toolchain, flake-utils }:
    flake-utils.lib.eachSystem [ "x86_64-linux" "x86_64-darwin" ] (system:
      let pkgs = nixpkgs.legacyPackages.${system}; in rec {
        packages.default = packages.ce-toolchain;
        packages.ce-toolchain = pkgs.stdenv.mkDerivation {
          src = toolchain;
          name = "ce-toolchain";
          patchPhase = ''
            substituteInPlace src/common.mk --replace-fail \
            "INSTALL_DIR := \$(DESTDIR)\$(PREFIX)" "INSTALL_DIR := $out"
            substituteInPlace makefile --replace-fail \
            "TOOLS := fasmg convbin convimg convfont cedev-config" \
            "TOOLS := fasmg cedev-config"
          '';
          doCheck = true;
          buildInputs = with pkgs; [ convbin convimg convfont fasmg llvm-ez80.packages.${system}.default ];
          meta.mainProgram = "cedev-config";
        };
      }
    );
}

And the full error Nix gave is:

warning: Git tree '/home/clevor/Code/flakes/ce-toolchain' is dirty
error:
       … while updating the lock file of flake 'git+file:///home/clevor/Code/flakes/ce-toolchain'

       … while updating the flake input 'toolchain'

       … while fetching the input 'git+https://github.com/CE-Programming/toolchain?submodules=1'

       error: '«unknown»/examples/graphx/template' does not exist

It's a submodule. Clone the repository correctly.

This is the only way to build the toolchain using Nix. If this doesn't get resolved, I would have to maintain a fork of the toolchain.

@mateoconlechuga if I clone the repository with git clone --recurse-submodules https://github.com/CE-Programming/toolchain.git the examples/graphx directory does not exist, and git submodule does not list it.

It's supposed to be this one iirc https://github.com/CE-Programming/graphx-template

Ok it's just because the parent directory got moved. It should be inside examples/library_examples/graphx/ nowadays.
