compilation failed

[candidobugarin]

Dear,

I'm starting the studies with Heltec Wifi LoRa V2 and following a tutorial to connect her to the LoRa network (https://robotzero.one/heltec-lora32-lorawan-node/), I found your library. However, when I compile the code, I find some flaws such as: sx1276-board.h: 55: 23: error: variable or field 'SX1276IoIrqInit' declared void
  void SX1276IoIrqInit (DioIrqHandler ** irqHandlers);

I have some experience in the programming part and at all it indicates to me missing any library or package being included in the project. Am I correct in my analysis? What would be the library? I researched here and elsewhere but found no answers.

Thank you very much
