Many of the Qt "demo" applications fail to function. They die with segmentation
faults on startup. Gdb doesn't display a useful stack trace - just zeros.
My build environment is a 'dd' image of the SD card root filesystem mounted via
loopback on a Ubuntu box. The Ubuntu box has qemu-user-static installed on it.
I run Qt's configure/make in a chroot() of the SD card root filesystem.
A few months ago I built Qt Embedded 4.7.3 for the TS-TPC-7390 running
Lenny/EABI and have been using it almost daily developing an HMI application.
It works fine as do the Qt demos.
Without useful gdb crash information I have no idea what's wrong. Playing
"divide and conquer" with my HMI application it seems like the crash is in Qt
somewhere related to fonts. If I comment out the calls to set larger font sizes
my HMI application doesn't crash.
If I can't get Qt running on the 8390 very soon I will have to bail on it for a
product design and revert to the 7390. Any help is most appreciated.
