How to nicely install processing with linux

Initial installation to have processing run

As root you have to

1.  Install the Sun JDK6 in a standard location, e.g. /usr/java
   1. Gets, e.g. jdk-6u21-linux-i586.bin, from http://www.oracle.com/technetwork/java/javase/downloads/index.html in /tmp
   2. Runs cd /usr/java ; /tmp/jdk-6u21-linux-i586.bin and follow instructions
2. Install the processing files
   1. Gets, e.g. processing-1.4.2.1.tgz from http://processing.org/download
   2. Copy processing in a standard location, e.g. /usr/java
      1. tar xvzf processing-1.4.2.1.tgz ; mv processing-1.2.1 /usr/java ; /bin/rm processing-1.4.2.1.tgz
   3. Adapt the preferences to Linux (assuimg here you use firefox and gnome)
      1. sed -i 's/brower.linux *= .*/browser.linux = firefox/' /usr/java/processing-1.2.1/lib/preferences.txt
      2. sed -i 's/[#]?launcher.linux *= .*/launcher.linux = gnome-open/' /usr/java/processing-1.2.1/lib/preferences.txt
3. Link the JDK6 to processing
   1. /bin/rm -rf /usr/java/processing-1.2.1/java ; ln -s /usr/java/jdk1.6.0_21 /usr/java/processing-1.2.1/java
4. You may have to install the proper sound/graphic librairies from the openjdk to the sunjdk (use locate libpulse-java.so to find the libraries in your system)
   1. cp /usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0/jre/lib/i386/libpulse-java.so /usr/java/jdk1.6.0_21/jre/lib/i386/
   2. cp /usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0/jre/lib/ext/pulse-java.jar /usr/java/jdk1.6.0_21/
   3. cp /usr/java/processing-1.2.1/libraries/opengl/library/*.so /usr/java/jdk1.6.0_21/jre/lib/i386/
5. To see the applets in firefox you may have to
   1. rpm -e java-1.6.0-openjdk-plugin erase the open-jdk web browser plugin
   2. ln -s /usr/java/jdk1.6.0_21/jre/plugin/i386/ns7/libjavaplugin_oji.so /usr/lib/mozilla/plugins install manually the JRE plugin
   3. for firefox-3.6 and latter
      1. ln -s /usr/java/jdk1.6.0_22/jre/lib/i386/libnpjp2.so /usr/lib/mozilla/plugins
6. Optionnaly install additional librairies if needed in /usr/java/processing-1.2.1/librairies

How to choose your sketchbook workdir

• Run /usr/java/processing-1.2.1/processing
• In $HOME/.processing/preferences.txt edit the sketchbook.path=<my-workdir> line for your convinience
• rm $HOME/sketchbook

Using you own processing starter (makefile commands)

P_HOME=/usr/java/processing-1.2.1
J_HOME=$(P_HOME)/java
export PATH:=$(J_HOME)/bin:$(PATH)
export CLASSPATH=$(shell echo '$(J_HOME)/lib/tools.jar $(J_HOME)/jre/lib/rt.jar $(wildcard $(P_HOME)/lib/*.jar)' | sed 's/ /:/g')

gui :
	@cd $(P_HOME) ; java processing.app.Base
