Qt 5.9.1 Known Issues
From Qt Wiki
- Check that your system meets Qt's requirements
- All open issues can be found from Jira: https://bugreports.qt.io
- RTA findings here: https://bugreports.qt.io/issues/?filter=18750
- The QML profiler will not record memory allocations. See https://bugreports.qt.io/browse/QTBUG-64674
- Static builds of Qt with Microsoft Visual Studio 2017 (through Update 2) do not work and will likely crash at runtime. This is believed to be a compiler bug and therefore an update from Microsoft is required. See https://bugreports.qt.io/browse/QTBUG-59721.
Building Qt modules fails with binaries delivered with online installer see bug QTBUG-53865. Workaround is to build whole Qt from source or have libicu 56 installed on the system.
- Opening projects in Qt Creator fails https://bugreports.qt.io/browse/QTBUG-61092 (iOS: qmake -spec macx-xcode fails to run compiler).
- Qt Creator uses the wrong mkspec for UWP projects using Visual Studio 2017. If you encounter errors like 'qt.winrtrunner: "<BUILDDIR>/AppxManifest.xml" does not exist.' please set the Kit's Qt mkspec to winrt-x86-msvc2017, winrt-x64-msvc2017 or winrt-arm-msvc2017 depending on target architecture. Afterwards rerun qmake, rebuild and run your application. https://bugreports.qt.io/browse/QTCREATORBUR-18288
- Should be fixed in QtCreator 4.3.1
- C++ debugging fails on QNX, see https://bugreports.qt.io/browse/QTCREATORBUG-17901
Qt for Device Creation
- Apalis iMX6: If you boot the device with USB cable plugged in, the debug connection to the device fails. Workaround is to disconnect and reconnect the USB cable after the device is booted up, see https://bugreports.qt.io/browse/QTBUG-61718
