Doesn't compile

On a RPi3 with a recent Arch Linux ARM running, this doesn't compile (GCC 8.2.0). I get lots of these errors:
RCSwitch.cpp: In member function 'char* RCSwitch::getCodeWordB(int, int, boolean)':
RCSwitch.cpp:218:12: error: invalid conversion from 'char' to 'char*' [-fpermissive]

Can confirm, same error on debian buster arm64v8

not using this anymore for some years now. please try the dev branch where i blindly applied possible fixes.
Does anyone got it now ? I've tried everything but nothing worked
