Arduino: 1.8.9 (Windows 10), Board: “Arduino/Genuino Mega or Mega 2560, ATmega2560 (Mega 2560)”

C:\Users\REXUS\AppData\Local\Temp\cc0lRoN1.ltrans0.ltrans.o: In function `main’:

collect2.exe: error: ld returned 1 exit status

Error compiling for board Arduino/Genuino Mega or Mega 2560.

This report would have more information with
“Show verbose output during compilation”
option enabled in File → Preferences.

Please start by reading this first.

Then you wont get corrupted text as your post shows.



Either you dont have loop() defined (all sketches must have setup and loop ) or you messed up the parens/braces elsewhere and the compiler didn’t complain about some other consequence of that first.
