Qt 5 cross compiled application not working on Raspberry Pi

[harshshah5789]

I used the ./bakeqtpi.bash script to install toolchain for Raspberry Pi by reading this page http://qt-project.org/wiki/RaspberryPi_Beginners_guide

I also configured the Qt Creator as mentioned in the page, added new kit and was able to successfully to cross compile.

Then using these steps :
@sync; sudo umount /mnt/rasp-pi-rootfs
sudo dd bs=1M if=2012-07-15-wheezy-raspbian.img of=/dev/sdb; sync@

I prepared the SD card and also copied my application binary in /home/pi/ folder in SD card.

Then I inserted the SD card in Rasp Pi and booted it after connecting to HDMI monitor.

The linux started successfully also 1st time config screen also came. I expanded the root fs and rebooted.

Then on the console I ran:
@cd /home/pi/
./App1
This plugin does not support setParent
This plugin does not support setParent
This plugin does not support setParent
This plugin does not support setParent@

I also tried :
@./App1 -qws
This plugin does not support setParent
This plugin does not support setParent
This plugin does not support setParent
This plugin does not support setParent@

But the same result.

My application is a simple app which has a textbox and button.

Could you post your source code for your simple project?

I compiled your code on my Raspberry Pi and had to make a few changes in the widget.ui file and I included the .pro file I used with qmake. Those files are as follows and the source files are the same as yours. I also used this link ("http://qt-project.org/wiki/Native_Build_of_Qt5_on_a_Raspberry_Pi":http://qt-project.org/wiki/Native_Build_of_Qt5_on_a_Raspberry_Pi) to build qmake on the pi. I ran the sample app, and it wasn't pretty, but it worked in both the console and in x-windows. Let me know if any of these help you.
