As Vass noted already a couple of things are not clear from your post.

You are working on Ubuntu, but you compiled Qt for an embedded device. If you want to work and test also on Ubuntu, than you have to compile Qt for for host platform Ubuntu as well.
Where are you starting your test application?

You can install different versions of Qt on your system. So, you can compile it for embedded devices and also for your host. However, you have to make sure that the installations are not mixed up.

i try with -fast flag and i hav'e error:

bq. Basic XLib functionality test failed!
You might need to modify the include and library search paths by editing
QMAKE_INCDIR_X11 and QMAKE_LIBDIR_X11 in /opt/qt-everywhere-opensource-src-4.7.4/mkspecs/linux-g++-64.

It looks that you have not installed all prequisites.
There are a couple of addtional libs you have to install under linux. Add xlib support to your installation. There may be more missing.

ok i install xlib ;) i have a last question - fast or no-fast ? What is the difference ?

This is the explanation from confgure script:
[quote]
@

-no-fast ........... Configure Qt normally by generating Makefiles for all
project files.
-fast .............. Configure Qt quickly by generating Makefiles only for
library and subdirectory targets. All other Makefiles
are created as wrappers, which will in turn run qmake.

It might be a matter of taste. I prefer the defaults, so -no-fast .

BTW there are explanations in the script ;-)
