Wouldn't it better to ask this in a Ubuntu forum?

Assuming that you might use also Qt dynamic libs on Ubuntu you could simply use those of the distrubtion.

maybe, i also ask this question in stackoverflow
but i think i have better chance to find a qt programmer that published an app in software center.
and about qt dynamic libs, maybe it help but i don't know how this system work.
for example, i know how rsa system protect my secret so i can use its related libs or modify it for my personal purpose but what about this system? can u explain how it work?

That is an Ubuntu-specific requirement, so most users on this forum don't know the answer.

The Ubuntu SDK is built on on top of Qt, so most Ubuntu app publishers know Qt. Your best chance is to ask at http://askubuntu.com/

Good luck!
