Electron Forge version

Electron version

v21.2.3

Operating system

Windows 11 - version 10.0.22621 Build 22621

Last known working Electron Forge version

Expected behavior

I am creating a universal build for max os. I have a fast API server running with electron and copying it into the resources directory by adding configs in pakagerConfig in forge.config.js.
Building individually for the x64 and arm64 works fine but when I pack it for universal using the command.

electron-forge package --arch universal

It should create the universal build for osx.

Actual behavior

I am creating a universal build for max os. I have a fast API server running with electron and copying it into the resources directory by adding configs in pakagerConfig in forge.config.js.
Building individually for the x64 and arm64 works fine but when I pack it for universal using the command.

electron-forge package --arch universal

It throws this error -

Error: Detected file "Contents/Resources/app-server/Crypto/Cipher/_ARC4.abi3.so" that's the same in both x64 and arm64 builds and not covered by the x64ArchFiles rule: "undefined"

Steps to reproduce

Command for packaging universal -

electron-forge package --arch universal

forge.config.js

 packagerConfig: {
    icon: process.platform==='darwin' ? path.resolve(__dirname, "AppIconMac.icns") : path.resolve(__dirname, "AppIcon.ico"),
    extraResource: path.resolve(__dirname, "./src/app-server"),
  },

This error happens when the same x64 binaries are present in both the x64 and arm64 versions of your app.

I think you would need to set up the x64ArchFiles configuration option for @electron/universal like this:

// forge.config.js
{
  packagerConfig: {
    osxUniversal: { // config options for `@electron/universal`
      x64ArchFiles: '**/_ARC4.abi3.so' // replace with any relevant glob pattern
    }
  }
}

Specifically you probably want these to be different between your builds. You could Allowlist it but your arm64 build should probably have an arm64 version of this file. Otherwise it may not run correctly on M1 hardware

Thanks for your response. Fixed this using

 x64ArchFiles: "*",

You would be running a lot of files under x64 emulation with that particular configuration. I would recommend a more fine-grained approach.

In any case, I'll close this issue out since it can be solved with configuration.
