Its getting compiled fine. But, when i import it and run , it throws the following error -

_### **_dyld: lazy symbol binding failed: Symbol not found: _hook_set_dispatch_proc
  Referenced from: /Users/mahadityakaushik/crewscaleagent/electron-dist/electron-darwin-x64-napi.node

I am not able to figure out, which library linking am i missing here. Btw it works very well with linux. Kudos

I don't own Mac device, that's the reason why it's not prebuilt. Open to pick up by commuinity

[BhuvanRohith]

Any idea when does that kind of error arise in c ?

[SnosMe]

Try to remove libuiohook target and merge its build steps into uiohook_napi

[bthalinda]

@BhuvanRohith did you found any solution ?

[BhuvanRohith]

Hey guys, anyone facing the similar issue on MAC , please try using this Binding.gyp. Adding the required defines in os=Mac definition resolved my issue, was able to build a Mac binary
