Just a quick followup. I had problems with DemoLinux. It wouldn't recognize my NIC.
So, I rebooted to FC3 (same machine) and attempted to redo all the steps from the How To.
Well, I had added the QT libs to the ld.so.conf file because I thought I had to. My mistake; I removed them. I went back to the original .sh files for setting up the compile environment and the tmake.conf files and made the minimum changes to reflect my GCC environment and VOILA! The Qtopia example program worked, locally and on my Zaurus! Woot!
So now I'm going after my killer app; using my Earthmate GPS (USB!) with the Z. Many people have written about getting their CF GPS's working with their Zaurii, but only myself and one other gentleman have posted concerning the USB Earthmate.
