Description

  • Node Version: node v15.11.0, npm 7.6.0, node-gyp v7.1.2, electron 9.3.3
  • Platform: macOS Catalina
  • Compiler:
    Apple clang version 12.0.0 (clang-1200.0.32.29)
    Target: x86_64-apple-darwin19.6.0
    Thread model: posix
    InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

I'm trying to include a dynamically linked library like so.

{
  "targets": [
    {
      "target_name": "addon",
      "sources": [ "addon.cc","file2.cpp" ],
      "include_dirs": [
        "<!(node -e \"require('nan')\")",
        "./include"
      ],
      "libraries": [ 
        "/Users/me/Documents/.../library.a",             
        "-L/Users/me/Documents/.../", "-lMyLibrary"
      ],
      'ldflags': [
      ],
      
    }
  ]
}

Compilation is successful, however runtime gives me error.

App threw an error during load
Error: dlopen(/Users/me/Documents/.../build/Release/addon.node, 1): Library not loaded: @executable_path/libMyLibrary.dylib
  Referenced from: /Users/me/Documents/.../build/Release/addon.node
  Reason: image not found

(sorry if this has been solved somewhere, i've looked at everything I could find, however I could of missed something, it's 3:30 AM right now as I type this 😅 )

Research direction

No repository file or test is named. Start with the provided target configuration and the macOS dlopen error, then inspect how node-gyp passes the library and linker settings to the addon. Done means identifying the runtime library-resolution issue and documenting the supported configuration or required change.
