The following steps were successful using the Gutsy Gibbon release (7.10) of ubuntu. All commands are executed from the command line.

First, you need to install the compilers and tools.

sudo apt-get install build-essential libncurses-dev bison flex texinfo zlib1g-dev gettext libssl-dev wget

Decide where you're going to build everything. I decided to create a directory called hammer in my home directory.

cd ~
mkdir -p hammer/source
cd hammer/source

Note: If you copy the whole directory tree from the CD, you'll get a directory called SOURCE which will be read-only. I prefer lowercase filenames, so I renamed the files. The files on the CD were also truncated to 8.3 filenames, so the names won't match what you see here.

Grab the latest files (these were from the Hammer_Board_Software page). This assumes that you're still in the source directory

wget http://www.elinux.org/images/4/4c/Buildroot-01032008.tar.gz
wget http://www.elinux.org/images/f/ff/Hammer-linux-2.6.22-09122007.diff.gz
wget http://www.elinux.org/images/e/ef/Hammer-kernel-config
wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.22.tar.gz

Build buildroot

tar xzf Buildroot-01032008.tar.gz
cd buildroot
cp Hammer-config .config
make oldconfig
make
cd ..

Add the cross compiler tools into your path. You may want to add this to your ~/.bashrc, although you should replace $(pwd) with the absolute path to your hammer/source directory.

export PATH=$(pwd)/buildroot/build_arm/staging_dir/bin:${PATH}

Build the kernel:

tar xzf linux-2.6.22.tar.gz
gunzip -c Hammer-linux-2.6.22-09122007.diff.gz | patch -p0
cd linux-2.6.22
cp hammer-config .config
make oldconfig
make zImage

The kernel can be found in arch/arm/boot/zImage
