It seem to work if I cast offset from Nan::New<Int32>(offset)) into Nan::New<Int32>((int)offset))

I got the same issue and using your suggestion the project built correctly but it fails during nfc reading:

@xantrix: Could you try applying the fix to this fork: https://github.com/athombv/node-nfc ?

[xantrix]

@jeroenvollenbrock I applied your fix at https://github.com/athombv/node-nfc/pull/1/files and it works like a charm! Thanks a lot!

[jeroenvollenbrock]

Good to hear, i'll prepare a pull request.
