Two days ago, I have posted a thread here saying that I can't run opie-camera properly on Cacko 1.22a.
The first thing if nothing happens is to try to launch from a terminal.
The best way to do so IMHO is to ssh into the Zaurus. Then, type "ps -ef" but not yet return. Then, launch the application on the Zaurus with the pen and press immediately return on your host. This should show the full launch command of the application - if that fails.
Then, you can try to run the same command manually and look for messages on the screen or in dmesg.
Another step could be to install gdb and ncurses5 and launch the program in gdb.
This all might help to find out about compatibilities.
Hope that helps a little.
