2. Compiling binutils

Checking the currently installed version of avr binutils

Run the following command:

avr-as  --version

Downloading the source code

Get the latest version from the binutils FTP site. We tested these instructions with version 2.19.1.

Unpacking the archive

Run the following command:

tar xzf ~/Desktop/binutils-2.19.1.tar.gz
cd binutils-2.19.1

Configuring and compiling binutils

The options given here just specify that the AVR version of binutils should be compiled:

./configure --prefix=/usr/local --target=avr
make
sudo make install

Next steps

You should now have the latest version of all of the binutils utilities compiled for the avr and installed in your /usr/local/bin. Proceed to Section 3 to install avr-gcc.
