Description of problem:

After following the instructions to make the LED light up I get errors when compiling. https://developer.amazon.com/en-US/docs/alexa/alexa-voice-service/indicate-device-state-with-leds.html
At this point I have tried a lot of different configurations and have found with all of the code changes per the instructions except adding the digitalWrite code the Alexa app works fine. However as soon as I add 1 digitalWrite command I get errors. 
I downloaded the latest WiringPi libraries for RPI 4 (ver 2.52) and can run the sample Blinky code with no problems. 

Expected:

To turn on a light. 

Problem-relevant config.yaml entries:

Steps to reproduce:

1. use digitalWrite in a script

case DialogUXState::IDLE:
digitalWrite (0, LOW);
ConsolePrinter::prettyPrint("Alexa is currently idle!");
return;

I think you are in a wrong repository. This is not the official Amazon stuff - https://github.com/alexa/avs-device-sdk
