error on compling with arduino ide

[megamarco833]

hi, i'm try to compile the example simplepotentiometer with arduino IDE and selecting my board nodemcu v1 ESP8266

i change inside the code:

dimmerLamp dimmer(outputPin, zerocross); //initialase port for dimmer for ESP8266, ESP32, Arduino due boards
//dimmerLamp dimmer(outputPin); //initialase port for dimmer for MEGA, Leonardo, UNO, Arduino M0, Arduino Zero

i'm using esp8266 library version 2.3

and those are the errors that i receive:
