This document is an adapted version of AVR libc tutorial.

Create a new directory, where the toolchain source files will be stored temporarily.

Run the following script! You will be asked for a password, as sudo command is used. User account with administrator (sudo) rights is required. wget tool is required to fetch source files from GNU sites. You can compile wget from sources on both: Linux and MacOS platforms.

#!/bin/bash

# will be installed under /usr/local. Change here, if other destination is needed
export PREFIX=/usr/local
