Download and Install

Right now, April/May 2014, RTB is only available for the Rasperry Pi running Raspbian. Older versions are still available for other platforms, but the Pi version is the only current one.

cd /tmp
wget http://unicorn.drogon.net/rtb-2.20-1.deb
sudo dpkg -i rtb-2.20-1.deb

That ought to install it, however it may throw up a dependency (most likely libsdl-sound), so to resolve this, then in the usual Debian manner:

sudo apt-get -f install

will complete the installation.

Finally get the demo programs:

cd
mkdir -p rtb
cd rtb
wget -O- http://project-downloads.drogon.net/rtb/demos.tgz | tar xfBz -
cd demos
ls

That will fetch the demo programs, and unpack them into a directory called demos, then change into that directory and display them for you. (this will eventually form part of the package, but for now, it’s a bit long-winded – sorry)

At this point you should be able to start RTB by typing:

rtb

RTB should work both in X Windows and in the console, but certain things like keyboard mappings may be different when run directly on the console.

RTB has a built-in DIR and LOAD command, so you can load up the demos and run them – e.g.

dir
load spiral
run

And off you go.

If you have used ssh to login to your Raspberry Pi from another Linux PC, then you can use the ssh -X command and RTB will run on the Pi and display locally, however it will be very slow as the SDL libraries do not lend themselves to speed when used like this.
