Processing.org 64-bit workaround

If this is the error you are receiving on your 64-bit Processing installation, fear not:

[susie@neptune processing-1.5.1]$ ./processing
[susie@neptune processing-1.5.1]$ Exception in thread “main” java.lang.UnsatisfiedLinkError: /home/susie/processing-1.5.1/java/lib/i386/xawt/libmawt.so: libXtst.so.6: cannot open shared object file: No such file or directory

Could not find the main class: processing.app.Base.  Program will exit.

I have a simple workaround for you.

1. Locate Java

   [susie@neptune ~]$ whereis java
   java: /usr/bin/java /usr/share/man/man1/java.1.gz
   [susie@neptune ~]$ stat /usr/bin/java
   File: `/usr/bin/java’ -> `/usr/lib/jvm/java-6-openjdk/bin/java‘

2. Use that Java instead

   [susie@neptune processing-1.5.1]$ mv java java.bak
   [susie@neptune processing-1.5.1]$ ln -T /usr/lib/jvm/java-6-openjdk ./java –symbolic

Tada! 奇跡です。
