This page describes setting up the AVR toolchain, needed to build code for the robostix and roboaudiostix boards.

Install compiler

When things work, you can do the following under ubuntu:

sudo apt-get install gcc-avr avr-libc gawk

However, some versions of avr-libc will give you compile errors when trying to build the i2c bootloader. (the error will mention __eerd_block). Ubuntu 9.04 installs a version of avr-libc with this problem. See below for details on manually installing a newer runtime library.

Manually install runtime library

The following steps can be used to install (or replace) the avr runtime library (avr-libc). Ubuntu-9.04 installs version 1.6.2, which has some issues.

tar xjf avr-libc-1.6.7.tar.bz2
cd avr-libc-1.6.7/
./configure --build=`./config.guess` --host=avr --prefix=/usr/lib
sudo make install
