I have installed MTS Mblaze application.

But I get the following error while running application.

~# ztemtapp
/usr/local/bin/ztemtApp/bin/App: error while loading shared libraries: libQtGui.so.4: cannot open shared object file: No such file or directory

I tried to install Qt.

apt-get install libQtGui.so.4

Installed i386 version of missing libraries one by one.

Now it is working.
