Please help. I have Ubunto 16.04 LTS, I am using Arduino 1.8.5 to flash Marlin firmware to Anet A8 3d printer board. I have folled the instructions on Github and when I compile it gives me these error warnings: In file included from /opt/arduino-1.8.5/hardware/arduino/avr/cores/arduino/Arduino.h:257:0, from
