Thats not a "Qt error", its a linker error and you're getting it because
your compiling against Qt4.5 headers, but the linker picks up Qt from a
Qt4.4 installation. Or the linker picks up some libraries from Qt4.4 and
some from Qt4.5. So check your system and build env for any remainings of
Qt4.4 (in particular development packages) and remove that.
