Thanks for your help - here's what I've done to date:




I used the latest version of Virtual Box (4.18) to create a virtual machine with 8Gb SATA HDD and 1GB of RAM.

I installed Ubuntu Desktop 11.04 with all the defaults

From the instructions at http://genode.org/documentation/developer-resources/getting_started as a base...

GNU make 3.81 - was already installed

I used apt-get install to install libSDL-dev

I initially had issues finding tclsh, as it wanted me to pick a version, but then I get it as part of   apt-get install tcl

I used apt-get to install expect,qemu,genisoinstall

Added virtualbox guest addins to get cut-paste working for this url

http://downloads.sourceforge.net/project/genode/genode/12.05/genode-12.05.tar.bz2?r=http%3A%2F%2Fsourceforge.net%2Fprojects%2Fgenode%2Ffiles%2Fgenode-toolchain%2F&ts=1342966018&use_mirror=iweb

I then renamed the file, and used   tar -xf to extract it...

Here's the output from the session after that...
