Qt-4.4.3 excecutable on S3C2440 gives segmentation fault

[soumya]

Hi all,

I want to run my customised qt application on ARM Board(S3C2440)..

I designed my application in QT4(version 4.4.3) which was already installed in my OPENSUSE(version 11.1) PC,my application is working fine in PC.

But when I tried to run on board I am getting segmentation fault.. The steps I followed are:

* I downloaded qt-embedded-4.4.3.tar.gz and added my application to example directory and cross compiled the package for ARM like ./configure -embedded arm -shared -no-cups , gmake..
after this I got arm executable of my application.
* I transfered this arm executable of my application to board and also qt libs to board,exported all QT environment variables..

When I tried to run this application on board, I am getting segmentation fault
But when I tried to run example application from qt-embedded-4.4.3 package even it gives the same error segmentation fault

I am not getting any clues also.so dont know how to proceed..


Can anyone faced this problem..?? or any suggesions are badly needed..

I have to debug this application using strace.. I dont know how to use strace on the target..
Please guide me from where i have to download strace and how should i use it in the target?

Thanks in advance:-)

Regards,
Soumya

hi,
for application to work environment variables and application path should be correctly specified ie., if you installed your qt embedded in /usr/local/qt , the application you want to run on your board should be in /usr/local/qt/bin (on your board) and also environment variables likie QTDIR,LD_LIBRARY_PATH should be correcly set.
i am using mini2440 board where i am running qt 4.5.3 on my board. if u want i will provide environment paths and qt application path of my boards.
u can check this link for reference
