Error compiling

Using Arduino IDE 1.x
1

When trying to verify my code, I get an error compiling. In case if it was my code, I try doing the same to multiple "example" codes and I get the same error. Help please :cry:

The error is
Serial.ino.cpp" -o ""
avr-g++: error: missing filename after '-o'

exit status 1
Error compiling.

The problem is caused by using Arduino AVR Boards 1.6.10 with Arduino IDE 1.6.6, they are incompatible. The options to fix this are:

  • Use Arduino IDE 1.6.7 or 1.6.8
  • Install Arduino AVR Boards 1.6.9 by: Tools > Board > Boards Manager... > Arduino AVR Boards(click on it) > Select version > 1.6.9 > Install. You will continue to get updatable notifications for the incompatible Arduino AVR Boards version so you might want to File > Preferences > Check for updates on startup(uncheck) to disable this notification.
