[SOLVED] Diagon Interactive ASCII art diagram generators build

Help
1

Hello,

I’m in the process of providing a build for GitHub - ArthurSonzogni/Diagon: Interactive ASCII art diagram generators. 🌟

What I currently have is a default.nix

# default.nix
{ pkgs ? import <nixpkgs> {}, ... }:
pkgs.stdenv.mkDerivation {
  name = "Diagon";
  src = builtins.fetchTarball https://github.com/ArthurSonzogni/Diagon/tarball/master;
  nativeBuildInputs = with pkgs; [ cmake pkgconfig git cacert (jre_minimal.override { jdk = jdk11_headless; }) ant ];
  buildInputs = with pkgs; [ boost libuuid icu ];
  propagatedBuildInputs = with pkgs; [ antlr ];

  meta = with pkgs.lib; {
      description = "Interactive ASCII art diagram generators. 🌟";
      longDescription = ''
          Diagon is an interactive interpreter. It transforms markdown-style expression into an ascii-art
          representation.        
      '';
      homepage = "https://github.com/ArthurSonzogni/Diagon";
    };
}

where I can

nix-shell --pure
eval cmake $cmakeFlags $src
make -j

The build (make) currently breaks:

[ 92%] Generating FlowchartLexer.cpp, FlowchartParser.cpp, FlowchartLexer.h, FlowchartParser.h
Error: Unable to access jarfile /nix/store/7g8306l1a9qxw7xswcdlbrm61v16wzi5-source/tools/antlr.jarGraphPlanarParser.h

EDIT:
Removed unnecessary zeromq and static-boost.
Added antlr as a buildInput. Still to no avail.

There is a warning related to antlr as well when I run the cmake command:

eval cmake $cmakeFlags -Wno-dev $src | grep -i warning

It is very roughly this, I can build using nix-build now:

# file default.nix
{ pkgs ? import <nixpkgs> {}, ... }:
pkgs.stdenv.mkDerivation {
  name = "env";
  src = pkgs.lib.cleanSource (builtins.fetchTarball https://github.com/ArthurSonzogni/Diagon/tarball/master);
  nativeBuildInputs = with pkgs; [ cmake pkgconfig git cacert (jre_minimal.override { jdk = jdk11_headless; }) ant extra-cmake-modules ];
  buildInputs = with pkgs; [ boost libuuid.dev icu ];

  # bc we have antlr already in the inputs

  # can be patched replacing by

  prePatch = "ls -lart tools";
  patches = [
    ./patch_cmakelists
  ];

  postPatch = ''
    substituteInPlace tools/CMakeLists.txt \
        --replace '-jar ''${DIAGON_TOOLS_DIR}/antlr.jar' '-jar ${pkgs.antlr.jarLocation}'
  '';

  propagatedBuildInputs = with pkgs; [ antlr ];
}
