Hi, Adam and Glenn, I prefer to build packages on the roach2 itself when needed. It's not too fast, but it is much easier than using ELDK (IMHO). To add missing packages (e.g. zlib1g-dev), one can run these commands on a netbooted roach2:
mount -o remount,rw / apt-get install zlib1g-dev mount -o remount,ro / Note that I had to delete the (SKA-SA specific?) /etc/apt/apt.conf.d/99proxy file to get apt to work on the roach2. I also changed the URL in /etc/apt/sources.list so that it would fetch packages from a nearby repository (rather than South Africa :-)).
