Is it possible to build Qt 5 without gestures on OS X?



  • Hi,

    I'm not intending to provide support for gestures in my application, yet Qt occasionally crashes (unfortunately this is not reliably reproducible) when attempting to handle gestures (I'm using a magic mouse). So I was wondering if there was some configuration option to disable gestures entirely? I've seen there's a define in the source code to achieve that but found no documentation as to how to set it when configuring Qt.

    For info, part of the crash log:
    Thread 0 Crashed:: Dispatch queue: com.apple.main-thread
    0   libQt5Widgets.5.dylib        
    0x00000001115b8e78 QGestureManager::getGestureTargets(QSet<QGesture*> const&, QHash<QWidget*, QList<QGesture*> >, QHash<QWidget, QList<QGesture*> >) + 1176

    Thanks in advance.



  • Did you build Qt from source of use the installer?

    I have never had a Qt crash on OS X (all crashes I experienced were from something I did wrong). I always install from the source and may have removed this part without realizing it (?).



  • I built it from source (version 5.3.1)
