Hi there, 
I just wanted to start to work with the new arduino portenta.
To start, I wanted to check the overall settings and path with an empty loop and an empty setup file:
// the setup function runs once when you press reset or power the board
void setup() {

}

// the loop function runs over and over again until power down or reset
void loop() {
   
}

I end up with a clean compile and a few hundred errors / warnings. 
Please advice how I can get rid of the errors / warnings
Thanks in advance.

Thank you very much, the error list is really confusing to me.
