I am trying to upload the Marlin Firmware to my 3D printer's Arduino Mega 2560 and I am experiencing a problem. It keeps saying:
qr_solve.cpp:7:18: fatal error: time.h: No such file or directory
#include <time.h>
^
compilation terminated.
Error compiling.
Please help as I'm lost as how to fix it, because I try to scroll up to see what is highlighted in red and I can't find anything.
