Hi! When I first open the Arduino IDE, I get this error message:
as: unrecognized option '-mmcu=atmega168'
At first I ignored this, but then when I compiled the code, I got
Couldn't determine program size: avr-size: '/tmp/build3344314702811629145.tmp/fader_blink.hex': No such file
and it doesn't finish compiling.
I'm on Kubuntu 8.10, using IDE version 0015 (I upgraded from 0012 in case that was the issue), and have an Arduino Duemilanove.
