Hello. I am using QtSingleApplication and QtService from QtSolutions in my applications. They work fine with Qt4, but I can't build them against Qt5:
Qt Code:

I'm running Ubuntu 12.04.1 LTS x64, Qt5 x64 is installed.

I've searched over the web and it seems like those classes use some deprecated functionality and should be replaced. Is there a way to use QtSolutions along with Qt5? Or are there new superseding classes in Qt5 framework?
