How To: Set up an AVR-GCC build environment from scratch.

Introduction: The main benefit of using Atmel's line of AVR microcontrollers is the well established avr-gcc toolchain, based on the free and open source gcc compiler. There is a nicely packaged distribution for Windows, but nothing nice for Linux users. Given that a compiler toolchain is fairly important, I thought I should try building my own. Reproduced below are my notes from installing all the components of the avr-gcc toolchain. It was based on the following guides and websites:

What You Get: You can either follow the guide at the bottom, or download the finished package below. Either way, you end up with a fully-functioning avr-gcc environment installed into /usr/local/avr, with the following tools:

Downloads: Click below to download the build notes or the finished toolchain package. If you find this to be useful, please send me an email. I'm always interested to know who's using my software.

Install Pre-Built Package: Here's how to install the pre-built package into /usr/local/avr:

  1. Download the package above (.tar.gz file) into your home directory.
  2. cd /usr/local
  3. sudo tar xvzf ~/avr_gcc_toolchain.tar.gz
  4. Be sure to add /usr/local/avr/bin to your path!

#
# If you have the usr_local_avr_toolchain.tar.gz and want to install that and
# not go to all the trouble of building these tools, do this:
#
# cd /usr/local
# sudo tar xvzf ~/usr_local_avr_toolchain.tar.gz
# 
# Be sure to add /usr/local/avr/bin to your path!
# You probably want to install these to work with the wnl code:
# sudo apt-get install subversion scons python-pexpect

# general setup
cd ~
mkdir avr_build

# add /usr/local/avr/bin to PATH, by adding this line to ~/.bashrc
export PATH=$PATH:/usr/local/avr/bin
# you should also do this for the root user, since using sudo can
# reset your PATH to root's default PATH
source ~/.bashrc

# install newer versions of MPFR and GMP dev packages
# required to build newer versions of gcc (ubuntu packages)
# also should pull in 4.1 versions of gcc
# The texinfo package is used while building binutils.
sudo apt-get install libgmp3-dev libmpfr-dev texinfo
