[Qt-interest] Qt 4.7.0 application Segmentation Fault on Mx51

[Donald Carr]

Hey Manoj,

What toolchain are using to compile Qt for the i.MX51?

I have deployed Qt 4.7 to that hardware without any hitches, my
primary suspicion is your toolchain.
What base system you using? (I think the standard Freescale BSP env is ALIP?)

Are you building it from scratch?

Worst case scenario you can enable a debug build of Qt and get a
better stack trace.

Please attach the qmake.conf from your mkspec

Yours sincerely,
Donald
