I'm running Arch Linux 64-bit and I have avr-gcc 4.6.0 installed, which can be found in the official repository on Arch. However, apparently there is a bug in this version which makes programs on my Arduino Mega 1280 unable to send and receive signals through the USB cable. I can install programs, but they can't communicate with the computer in Serial Monitor in Arduino. (Hope you understand what I mean.)
I have read that installing 4.3.x of avr-gcc should fix this problem. But I can only find version 4.3.4 of gcc in the AUR (Arch User Repository), and not an older version of avr-gcc.
So my question is: where can I find version 4.3 of avr-gcc? And how do I install it?
