I recommend you first try your installation on Qt4.

> Subject: epicsqt with Qt5.1.1, Qt-Creator 2.8.1
> Dear QTi-talk,
> I am trying to compile epicsqt 2.7.1 with
> very standard installation of Qt5.1.1 and install
> its plugin into designer under Qt-creator 2.8.1 on
> Scientific Linux 6.4 (kernel 2.6.32-358.18.1.el6.i686).
> The Creator itself was build from src under the same version of Qt.
> The QWT version is 6.1.0. It was also build from src and seems
> working ok (all examples are working fine).
> EPICS base22.214.171.124 is installed and all env. variables are defined.
> After all standard changes http://qt-project.org/wiki/Transition_from_Qt_4.x_to_Qt5
> applied to epicsqt 2.7.1 it was built without any errors
> (just warnings about QE_ARCHIVE_LIST is not defined).
> After that I have defined QT_PLUGIN_PATH pointed to framework folder
> where designer folder with libQEPlugin.so was.
> Unfortunately this library always return
> "Plugin verification data mismatch" on loading.
> Does anyone had a similar problem and know how to solve it?
> Below is a list of my environment.
