Ok, I also copied the content of /jjack/lib/i386 to the processing/lib directory (that is so it looks like processing/lib/i386).

Now it seems to connect to Jack at first but then it disconnects and I get this error:
"jack_client_thread zombified - exiting from JACK"

I got that error because I was running jack in 'realtime' mode. When I unchecked that it works fine :D

Hey!
I read the instructions, but I cannot proceed. I added the file to the project, but I do not know what to write in import. They have this weird import de.gulden.framework.jjack.*; It does not work for me. How did you do it?

Hi,

How to use Jack + Processing

1. Download jjack http://download.berlios.de/jjack/jjack-0.3.tar.gz
2. Unpack jjack
3. Copy libjjack.so to the appropriate Processing lib directory:
   • sudo cp -R jjack-0.3/lib/i386 /usr/local/src/processing/lib/
4. In Processing: File - Examples - Libraries - Minim(Sound) - GetLineIn
5. Import the appropriate jjack library on the sketch adding this line:
   • import de.gulden.framework.jjack.*;
6. Add jjack-0.3/lib/jjack.jar to the sketch. In Processing: Sketch - Add File (...) and select the jjack.jar file
7. Start Jack (qjackctl?)
8. Run the GetLineIn sketch
9. Run some audio jack compatible program
10. Connect the output of the audio program to the input of jjack on Jack
11. Have fun! :-)
