Failed to build desktop application

[frisodubach]

Describe your Environment
OS: NixOS 24.05
Paisa Version: 0.6.6
App Variant: Desktop

Describe the bug
Failure to build desktop application using the nix dev shell on NixOS 24.05.

To Reproduce
Steps to reproduce the behavior:

1. Clone repo
2. Enter dev-shell with nix develop
3. Run wails build
4. Receive error:

# Building target: linux/amd64

  • Generating bindings:   ERROR   
          ../web/web.go:7:12: pattern all:static: no matching files found
          
          exit status 1

  ERROR   
          ../web/web.go:7:12: pattern all:static: no matching files found
          
          exit status 1

I tried searching for any file matching static, and noticed there is a entry in the .gitignore: web/static.
Is there a step I'm possibly missing regarding the build process?
There is no documentation on how the application should be built, so I'm not too sure on what to do.
I was trying to build the desktop app such that I could see if I can add it to the nix-flake, but I'm a bit lost here.

Expected behavior
A successful build of the desktop application using wails.

@frisodubach look at the Makefile, I think you should start with make install. It's failing because javascript/html resources are missing which are generated by npm run build.

I will move this to discussion, as it's not a bug rather a question.

Hey @ananthakumaran, thanks for the reply. I actually made a lot of progress on the desktop flake already. This is the addition to the flake currently, however it's failing to build. It's specifically failing with the npm run build command defined in the configurePhase. I'm not sure why this is the case, as it's the same as you had defined for paisa-cli. For some reason, I'm getting the error that npm can't find the /build/packages.json, eventhough it is able to find it during the npm install step (or at least I assume so as otherwise it would have failed there.

        packages.paisa-desktop = let
          version = "0.6.6";
          inherit (pkgs) mkdocs stdenv lib;
        in stdenv.mkDerivation {
          name = "paisa-desktop-${version}";

          # src = pkgs.fetchurl {
          #   url = "https://github.com/ananthakumaran/paisa";
          #   sha256 = "";
          # };

          src = ./.;

          dontUnpack = true;
          sourceRoot = ./.;

          nativeBuildInputs = [
            pkgs.nodejs-18_x
            pkgs.wails
            pkgs.pkg-config
            pkgs.patchelf
            pkgs.webkitgtk
            pkgs.gtk3
            pkgs.go_1_21
          ];

          buildInputs = [ pkgs.ledger ];

          configurePhase = ''
            ln -s ${nodeDependencies}/lib/node_modules ./node_modules
            export PATH="${nodeDependencies}/.bin:$PATH"
            npm run build
          '';

          buildPhase = ''
            go mod download && go mod verify
            go build
            cd desktop
            wails build -o paisa-desktop -clean
          '';

          installPhase = ''
            mkdir -p $out/bin
            cp paisa-desktop $out/bin
          '';

          meta = {
            homepage = "https://paisa.fyi/";
            description = "Paisa – Personal Finance Manager.";
          };
        };

I've been stuck on this for about a day now, struggling to debug the issue. Running each individual build phase separately with nix develop .#paisa-desktop doesn't result in the same error however, which is very odd to me.
I don't understand npm at all so possibly it's just an issue there?

Any help / suggestions would be appreciated, as I think it's close to being done but the whole nodeDependencies and overrides are quite complicated and thus opaque to me. So it's hard for me to debug what exactly is happening there.

Exact build error for reference:

From what I can understand, I think the error lies somewhere in the node-env.nix file. Here a package.json file is created, and eventually cd up two directories, which seems to happen when I manually run the phases as well, suddenly ending up two directories higher.
I'm not quite sure how or why this file was created, but it doesn't seem consistently reproducible. Maybe it only consistently works for your environment?

I got it to mostly work (after having a broken laptop for over a week).

        packages.paisa-desktop = let
          fs = lib.fileset;
          sourceFiles = ./.;
          version = "0.6.6";
          inherit (pkgs) mkdocs stdenv lib;
        in pkgs.buildGoModule {
          pname = "paisa-desktop-${version}";
          meta.mainProgram = "paisa-desktop";
          version = version;

          # src = pkgs.fetchurl {
          #   url = "https://github.com/ananthakumaran/paisa";
          #   sha256 = "";
          # };

          src = fs.toSource {
            root = ./.;
            fileset = sourceFiles;
          };

          dontUnpack = false;

          nativeBuildInputs = [
            pkgs.nodejs-18_x
            pkgs.wails

            pkgs.patchelf
            pkgs.webkitgtk
            pkgs.gtk3
            pkgs.go_1_21
          ];
          vendorHash = "sha256-ztpPOYxPajS9fhbVxirplQS1E899UW9P6Q2D5XHAfv4=";
          # vendorSha256 = lib.fakeHash;

          CGO_ENABLED = 1;

          doCheck = false;

          subPackages = [ "." ];

          buildInputs = [ pkgs.ledger ];

          preConfigure = ''
            ln -s ${nodeDependencies}/lib/node_modules ./node_modules
            export PATH="${nodeDependencies}/.bin:$PATH"
            npm run build
          '';

          # preBuild = ''
          #   go mod download && go mod verify
          #   go build
          # '';

          buildPhase = ''
            # go mod download && go mod verify
            # go build
            go mod vendor
            cd desktop
            # wails build -o paisa-desktop -clean
            wails build -o paisa-desktop
          '';

          installPhase = ''
            mkdir -p $out/bin
            cp paisa-desktop $out/bin
          '';

          # proxyVendor = true;

          meta = {
            homepage = "https://paisa.fyi/";
            description = "Paisa – Personal Finance Manager.";
          };
        };
 

However, I'm running into issues with the go-modules being fetched. Namely, I get the error:

error: builder for '/nix/store/91j2ny5gy5m9y3inw2b5n2kdiv6n5s89-paisa-desktop-0.6.6-0.6.6.drv' failed with exit code 1;

I can't really figure out what to do to fix this, so I'm currently stuck.
