Hi,
what board are you using?

eko_1

The cpu is LPC3250 from NXP & I using cross compiler arm Qt4.7.4 by following the instructions on this link:

"Qt for embedded platforms on LPC3250 - Thumb mode error on make":http://developer.qt.nokia.com/forums/viewthread/7304/
"[SOLVED] cross compile arm qt4.7.4 with -debug":http://developer.qt.nokia.com/forums/viewthread/9946/

Obviously the libc/glibc version differs from the target to the host.

I had the same problem, when cross-compiling Qt on Ubuntu 10.04 host and executing the application on a Debian Lenny target.
To solve the problem, I set up a Debian VM and cross-compiled Qt on a debian host.

I hope this could solve your problem as well.

Regards,
