antlr.jar not found

[573]

I find this a wonderful project, thanks for making it.

When trying to package for NixOS I found that my build stuck at locating the antlr.jar:

Consolidate compiler generated dependencies of target antlr4_static [ 92%] Built target antlr4_static [ 92%] Generating GraphPlanarLexer.cpp, GraphPlanarParser.cpp, GraphPlanarLexer.h, GraphPlanarParser.h [ 92%] Generating FlowchartLexer.cpp, FlowchartParser.cpp, FlowchartLexer.h, FlowchartParser.h [ 92%] Generating MathLexer.cpp, MathParser.cpp, MathLexer.h, MathParser.h [ 92%] Generating SequenceLexer.cpp, SequenceParser.cpp, SequenceLexer.h, SequenceParser.h Error: Unable to access jarfile /nix/store/7g8306l1a9qxw7xswcdlbrm61v16wzi5-source/tools/antlr.jar

I'm pretty much a beginner coming to cmake or even nix, maybe you have a clue and can give a nudge here ?

This my default.nix for the build so far:

{ pkgs ? import <nixpkgs> {}, ... }:
pkgs.stdenv.mkDerivation {
  name = "Diagon";
  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 ];
  buildInputs = with pkgs; [ boost libuuid.dev icu ];
  propagatedBuildInputs = with pkgs; [ antlr ];
}

Also I'm getting

This is about this line: https://github.com/ArthurSonzogni/Diagon/blob/master/tools/download_and_patch.sh#L8

I see this error:

Warning: Failed to create the file antlr.jar: Permission denied

Do you know why the permission to create a file is denied? Are you owning the current directory?

Inside "Diagon/tools", what is the output of:

ls -lart

?

I'll have to recheck later what the real permissions are as I download the sources while building. For now thanks for your input, I'll be back with progress.

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 ];

  # the https://github.com/ArthurSonzogni/Diagon/blob/master/tools/download_and_patch.sh should not be needed
  # bc we have antlr already in the inputs

  # can be patched replacing by
  # -jar ${pkgs.antlr.jarLocation}
  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 ];
}
