I think we're in luck, then... I just found the Zaurus Open Source Development page on Sourceforge. They have gdb 5.1.1 for ARM. I downloaded it, and gave it a try. The only complaint I got was that it couldn't find libncurses.so.4. The empeg uses libncurses.so.5. After doing a ln -s libncurses.so.5 libncurses.so.4, gdb worked. Slowly, but it worked.

Cheers,
A
