processing in Puppy Linux
Nov 13th, 2008, 2:13pm  
Hi,
I'm new to this forum. I used shortly processing under mac os x but now I moved to linux, so I'm trying to install processing here.

I get the following error when I start processing:
# ./processing
BusyBox v1.8.2 (2007-11-30 09:20:42 GMT-8) multi-call binary

Usage: dirname FILENAME

Strip non-directory suffix from FILENAME

Exception in thread "main" java.lang.NoClassDefFoundError: processing/app/Base
Caused by: java.lang.ClassNotFoundException: processing.app.Base
       at java.net.URLClassLoader$1.run(URLClassLoader.java:200)
       at java.security.AccessController.doPrivileged(Native Method)
       at java.net.URLClassLoader.findClass(URLClassLoader.java:188)
       at java.lang.ClassLoader.loadClass(ClassLoader.java:307)
       at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)
       at java.lang.ClassLoader.loadClass(ClassLoader.java:252)
       at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320)
Could not find the main class: processing.app.Base.  Program will exit.

What I did, step by step, is:
1) download and install (to /usr/local)
sdk-6u10-nb-6_1-linux-ml.sh
2) added to my /etc/profile:
export PATH=$PATH:/usr/local/jdk1.6.0_10/bin
export JAVA_HOME=/usr/local/jdk1.6.0_10
3)download and install processing0156 (also to /usr/local)
4) moved the java folder within processing folder to java_bak
5) (from processing folder) ln -s /usr/local/jdk1.6.0_10 java

Java seems to work ok, I did a test on a very simple HelloWorld.java file and it worked, however, I receive this error when I start processing.
I googled around and checked the forum, but cannot go further with it.

Thanks for your help.
Best regards,
Libero Mureddu

looks like the 'dirname' function isn't supported by your shell. the processing shell script uses dirname to get an absolute path to the installation. you should hand-edit the 'processing' shell script to make it work for your machine without dirname.

Hi, thanks for your answer.
I'm still a newbie, so I can be wrong, but I tried the following in a terminal and it seems to work.

# dirname /usr/local/processing-0156/
/usr/local

However, I noticed that in the script there are two lines:
java/lib/rt.jar \
java/lib/tools.jar \

However, in my java installation, tools.jar is in the java/lib directory, while rt.jar is in java/jre/lib (where the "java" folder is the symlink to my sdk installation). But I have no idea if this is a problem or not.

Thanks,
Libero

Hi, I solved it changing this line,

APPDIR="$(dirname -- "${0}")"

to

APPDIR=/usr/local/processing-0156

and now it works (even if I don't have any idea about why the original line didn't work. I guess it's probably related with dirname, as you said).

Thanks a lot,
