[kacesensitive]

Describe the bug

So i have a tauri app which needs to run a sidecar application. Here is my tauri config

  "$schema": "../node_modules/@tauri-apps/cli/schema.json",
  "build": {
    "beforeBuildCommand": "npm run build",
    "beforeDevCommand": "npm run dev",
    "devPath": "http://localhost:3000",

        "icons/icon.icns",
        "icons/icon.ico"
      ],
      "identifier": "com.kacey.dev",

    },
    "security": {
      "csp": ""
    },
    "updater": {
      "active": false
    },
    "windows": [
      {
        "title": "ProChat",
        "label": "prochat-app-v2",
        "width": 800,
        "height": 600,
        "resizable": true,
        "fullscreen": false,
        "transparent": false,
        "url": "/"
      },
      {
        "title": "ProChat Engineer",
        "label": "prochat-app-v2-secondary",
        "width": 800,
        "height": 600,
        "resizable": true,
        "fullscreen": false,
        "transparent": false,
        "url": "/engineer"
      }
    ]
  }
}

And here is the folder structure in the image

When running the binary with the following

const startChatServer = async () => {
        const platform = await os.platform(); // 'darwin', 'linux', or 'win32'
        let binaryName = '';

        if (platform === 'win32') {
            binaryName = 'chatserver-win.exe';
        } else if (platform === 'darwin') {
            binaryName = 'chatserver-macos-aarch64-apple-darwin';
        } else if (platform === 'linux') {
            binaryName = 'chatserver-linux';
        }

        const command = Command.sidecar(`bin/${binaryName}`);
        try {
            const output = await command.execute();
            console.log('Chat server started:', output);
        } catch (error) {
            console.error('Failed to start chat server:', error);
        }
    };

I am getting

[Error] Failed to start chat server: – "sidecar not configured under `tauri.conf.json > tauri > bundle > externalBin`: bin/chatserver-macos-aarch64-apple-darwin"
    (anonymous function) (app-index.js:33)
    (anonymous function) (hydration-error-info.js:41)
    (anonymous function) (Control.tsx:60)```

Fine... then i'll add bin/chatserver-macos-aarch64-apple-darwin to the config But then my buiild fails with

Caused by:
  process didn't exit successfully: /Users/kc/Desktop/Code/prochat-app-v2/src-tauri/target/debug/build/app-62d9b38b50c54525/build-script-build (exit status: 1)

  cargo:rustc-cfg=desktop
  cargo:rustc-cfg=dev
  path matching bin/chatserver-macos-aarch64-apple-darwin-aarch64-apple-darwin not found.

I'm just confused, any help more than welcome!!

[FabianLars]

at first glance your initial approach was almost correct, you just had to change binaryName = 'chatserver-macos-aarch64-apple-darwin'; to binaryName = 'chatserver-macos'; -> The actual binary on the filesystem still needs that prefix.

Btw the idea here is that you don't need this manual binaryName handling. Just use bin/chatserver in externalBin and in your js code and name your actual binaries chatserver-${target-triplet} and tauri will care about loading the correct one.

Heck yeah. Thanks a ton! @FabianLars
