I've recently got back to my Uno. I tried compiling my program and got the following error:

Arduino: 1.6.6 (Windows 8.1), Board: "Arduino/Genuino Uno"

avr-g++: error: missing filename after '-o'

exit status 1
Error compiling.

This happens on any of the programs I've tried to compile/upload. I've searched around on Google but I have gotten no definite answers and how to fix this or what has caused this? Does anyone have an idea on what I could do?

I had same problem. You should download Arduino IDE 1.6.8
