How to run Processing on your Raspberry PI?

Processing is an open source programming language (processing.org) and environment for people who want to create images, animations, and interactions.

This is how to install it on your Raspberry PI:

• install the java 6 sdk
  sudo apt-get install librxtx-java openjdk-6-jdk
• download and unzip the Linux (x86) version of Processing 1.5.1 to the /home/pi directory
  http://download.processing.org/processing-1.5.1-linux.tgz
• change your working directory to /home/pi/processing-1.5.1 before executing the following commands
  cd /home/pi/processing-1.5.1
• delete the directory /home/pi/processing-1.5.1/java
  sudo rm -rf java
• create a symbolic link to the system’s java SDK
  sudo ln -s /usr/lib/jvm/java-6-openjdk-armhf java
• delete the RXTXcomm.jar file
  sudo rm modes/java/libraries/serial/library/RXTXcomm.jar
• copy the system’s RXTXcomm.jar file
  cp /usr/share/java/RXTXcomm.jar modes/java/libraries/serial/library/
• fire up Processing from the file manager (or LZTerminal)
  (ignore the ‘Not found of this java VM‘ warning!)

PROCESSING IS NOW UP-AND-RUNNING!!!

Use this same tutorial for installing the current beta version of Processing (2.0b7)!
