I have had a go at creating a script to do most of the work involved in creating a development environment. It should set up a directory structure and download and compile all the tools required to either use vomp over a NFS root or build dongles. The only things the script doesn't do are: Set up your DHCP/TFTP/NFS for NFS root development, and the final dongle build creation (since you need a Hauppauge dongle to do it).
Make sure you execute this script in an empty directory!!!
As long as you have C/C++ development tools, wget and bzip2 installed this script should work. I have tested it on Debian Woody and Sarge, Ubuntu Breezy and Fedora Core 5.
Please post success and failure stories to the forum so I can improve the script.
