OpenCV on mini2440

Hi all,
i got a problem

i am able to run opencv in mini2440
but the problem is not all the functions like cvWaitKey(),
cvCaptureFromCAM() etc.

what could be the reason ...??

i am using the following specifications ...

on host machine <<<< ------
ubuntu 10.04
opencv2.1.0
cmake 2.8.0
gcc 4.4.3

on target machine <<<< -----
mini2440
vivi bootloader 
kernel 2.6.32
qutopia 2.2.0
uvc compatible webcam

i also checked with microsoft webcam too ... but no use.

did any one have the solution/suggestion ...??

Your system don't have gtk,so it can't show windows.
But we seldom use gtk in ARM-linux.
QT is a good choice,but i don't know how to deal with it,either.

@punith can u please post the steps on how u compiled opencv for arm and
how u ported the program on mini2440
