I was last trying to get my WiFi shield up and running so there are some wifi settings being used.
When I compile even a very basic sketch, I get the same error message:
fork/exec /Users/BD1USA/Library/Arduino15/packages/arduino/tools/avr-gcc/7.3.0-atmel3.6.1-arduino5/bin/avr-g++: no such file or directory
Error compiling for board Arduino Uno.
Not sure why??
Under TOOLS, there is a setting:
WiFi 101/ WiFiNINA Firmware Updater.
Maybe this is also an issue ??
Any suggestions are greatly appreciated !
