Compiling trolley software

The trolley computer uses a low-power ARM processor with limited resources. It does not have the resources to compile the trolley software, hence it is necessary to use a cross-compiler on a desktop PC to compile the code. This was fairly straightforward in 2005 when the COAST group started development for this board, but the computer world has moved on a very long way since then. Here is how EBS solved the problem.

The essence of the solution is to generate a virtual PC on your desktop PC and install an old Linux distribution, circa 2006, in that.

What you will need

You can download old Debian network install CDs from here.

Installing a virtual machine

There are two major free virtual machines available for Linux, these are VirtualBox and KVM. EBS used KVM but there is no compelling reason to choose one over the other. Set up your virtual machine, ensuring that the resulting machine has:

Installing your retro Linux distribution

This depends on your distribution. You want something with an early 2.6 Linux kernel. For Debian etch using a network install:

deb http://archive.debian.org/debian-archive/debian/ etch main
deb-src http://archive.debian.org/debian-archive/debian/ etch main
apt-get update
apt-get upgrade
 apt-get install some-held-back-package.deb
 apt-get install linux-image-2.6-686

Install the Arcom development environment

perl [your CD mount point]/.install
 export PATH="/opt/arcom/bin:$PATH"

Build the Arcom kernel source

This step is necessary to allow the compilation of the trolley kernel modules.

 dpkg -i ./linux-source-2.6.11.11-arcom3_2.6.11.11-3_all.deb
 tar -xvf /usr/src/linux-source-2.6.11.11-arcom3.tar.gz
 make ARCH=arm viper_defconfig
 ael-kernel-build --architecture=arm image

Compile the trolley software

 svn checkout http://appcs.ra.phy.cam.ac.uk:8080/svn/coast-repos/dl/commonlibs
 svn checkout http://appcs.ra.phy.cam.ac.uk:8080/svn/coast-repos/dl/trolley
 make
 make install (as root)
 make clean
 make arch=arm
 make arch=arm install
 make
 make package

That last command packages up the executables, to be sent to the trolley computer for later unpacking and installation using the included scripts.
