Thanks Wysota for your response.

I have another machine having
Qt creator 2.2.1 based on Qt 4.7.4 (32 bit)
source version of Qt is Qt-4.8.0.
uname -a returning
Linux ravi-desktop 3.0.0-15-generic #26-Ubuntu SMP Fri Jan 20 15:59:53 UTC 2012 i686 i686 i386 GNU/Linux

The static as well as shared linking works fine on above mentioned system. There is no difference of UI at all between statically linking and shared linking. Only one issue is that application is littlebit slow.

what may be the problem on my system?

Can i compile static application on another machine both for 32 bit and 64 bit Ubuntu system and how?

Thanks in advance.
