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

Using Arduino IDE 1.x
15

I have no good excuse for using 1.6.6. It's just the one I've been using and had no cause to update until now.

So now I've installed Arduino 1.8.5, and I have a different problem... It no longer recognizes the intrinsic class "keyboard" for the Arduino pro-micro. I'm using "Sparkfun AVR board 1.1.9".

Any thoughts?

Thanks again.
