Hi,

Just in case, the qtsolution module is available at http://code.qt.io/cgit/qt-solutions/qt-solutions.git/ with build fixes for Qt 5.

The QtSingleApplication module is working with Qt 5. However it doesn’t provide support for QGuiApplication but it’s not hard to add it if needed.

Cheers
Samuel
