I'm trying to follow the instructions on compiling Processing from source, here:

http://code.google.com/p/processing/wiki/BuildInstructions

which says:

cd /path/to/processing/build/linux  and ./make.sh

sadly, there's no make.sh there.  there is a "processing" file, which seems to be designed to run processing once it's been built.  Executing it returns this error:

Exception in thread "main" java.lang.NoClassDefFoundError: processing/app/Base
Caused by: java.lang.ClassNotFoundException: processing.app.Base
at java.net.URLClassLoader$1.run(URLClassLoader.java:202)

at java.lang.ClassLoader.loadClass(ClassLoader.java:248)
Could not find the main class: processing.app.Base. Program will exit.

There are three make.sh files in the entire processing-read-only directory:

processing-read-only/processing/build/javadoc/make.sh

processing-read-only/processing/build/shared/tools/Mangler/make.sh

processing-read-only/processing/core/make.sh

That last one seemed to hold potential, but running it returns the error:

chmod: cannot access `preproc.pl': No such file or directory
./make.sh: 6: ./preproc.pl: not found
./make.sh: 7: jikes: not found

Has anyone compiled Processing from source?  How?

Thanks,

Ben
