cannot find -lQtGui -QT Beginner Help Needed

Hi ,
Iam a absolute Beginner in QT and Linux .

Iam trying to develop a sample Application which runs on ARM Processor(PXA270).
For this i downloaded qt-sdk-linux-x86-opensource-2009.03.1 ,created a small application which has few button and Label
It ran perfectly in Linux Machine(Fedora 9) ,

Next thing i need is make it work in ARM Linux .


I tried qmake,Makefile was created successfully.

But when I run make it was showing the following:


[nsa@WS111 s]$ qmake-qt4 -spec /usr/local/QT/qt/mkspecs/qws/linux-arm-g++ -o Makefile s.pro
[nsa@WS111 s]$ make
arm-linux-g++ -Wl,-O1 -o s -L/usr/lib -lQtGui -L/usr/lib -L/usr/X11R6/lib -lQtNetwork -lQtCore -lpthread
/usr/local/arm/4.0.0/usr/bin/../lib/gcc/arm-linux/4.0.0/../../../../arm-linux/bin/ld: skipping incompatible /usr/lib/libQtGui.so when searching for -lQtGui
/usr/local/arm/4.0.0/usr/bin/../lib/gcc/arm-linux/4.0.0/../../../../arm-linux/bin/ld: skipping incompatible /usr/lib/libQtGui.so when searching for -lQtGui
/usr/local/arm/4.0.0/usr/bin/../lib/gcc/arm-linux/4.0.0/../../../../arm-linux/bin/ld: cannot find -lQtGui
collect2: ld returned 1 exit status
make: *** [s] Error 1
[nsa@WS111 s]$

Thanks for the reply,
Iam not able to run the Application in board,

Should i recompile the existing application in qt-embedded-free-3.3.7 environment to make it board compatible ?

Could you please briefly explain the steps needed
OS version is Fedora 9

can cross compiling done from Qtcreator?

Kindly reply,
Thanks again

Please refer the given post, in that, user "soumya" written the steps for setting up the development environment for ARM. In same post, you can find the steps for deploying application. This is very useful for you.

QtCreator is just IDE, and has nothing to do with cross compilation.
And there are many posts exists for cross compilation on QtCentre.

Thanks Yogesh,
I will Check the link you pasted,

We downloaded QtEmbedded-4.5.2
Then we followed the below steps

Step 1:
./configure -embedded arm -shared -no-cups

Step 2:

gmake;

The contents in the installation folder:
are bin include lib no other folders are created.


[root@WS111 examples]# cd /usr/local/
[root@WS111 local]# cd Trolltech/
[root@WS111 Trolltech]# cd QtEmbedded-4.5.2-arm/
[root@WS111 QtEmbedded-4.5.2-arm]# ls
bin include lib
[root@WS111 QtEmbedded-4.5.2-arm]#

The examples folder was not visible .
Did i miss any intermediate steps?
Please help
