ResolveLibrary(IRLremote.h)

Compilation error: Error: 13 INTERNAL: exit status 1

Hi @enalj. This is currently the Arduino IDE 2.x version of the more intuitive "No such file or directory" error you would get from the classic Arduino IDE.

This error is almost always caused by not having the library installed that provides the mentioned file ("IRLremote.h" in this case). However, in this particular case, the filename closely resembles the "IRremote.h" file that is part of the very popular "IRremote" library. Is it possible you misspelled the filename, or is the file really named "IRLremote.h"?
