I’m new here (French guy, sorry for the mistakes ).
I’ve purchased an Arduino MKRZero recently and tried to run some sketch on it.
In particularly, I used, for exemple, the librairie SD.h which worked.
But, I’ve also tried I2Cdev.h , u8glib.h , SoftwareSerial.h or SomeSerial.h which didn’t worked.
Here is the error I have for I2Cdev, in the file I attached.
