Actually there are several versions of Qt5 that do not even compile when setting qreal=float. After reporting such a bug the fix did not even go into the relevant LTS version ( Qt 5.9 at that time ). Obviously building with qreal=float seems not to be covered by the Qt tests and also does not seem to be seen as import by the development. But the whole concept of qreal is questionable as it implies, that how to store values is always related to the hardware architecture and/or rendering. For a library like Qwt this is not the case and and algos like f.e spline interpolation suffer, when using QPointF an friends. So yes, please remove the qreal=float option with Qt6.
