Qt 5.9.8 Known Issues

All platforms

• Check that your system meets Qt's requirements
• All open issues can be found from Jira: https://bugreports.qt.io
  • RTA findings for Qt 5.9.8 here
• Old qt-unified-online-installer-3.0.1 (or older) can't any more be used to get Qt 5.9.4 (or later releases), see QTBUG-65798
  • For new installations use newest online installer. For existing installations please update maintenance tool at first.
• Widevine support in QtWebEngine requires a widevine plugin from Chrome 61 or older, 62+ has a different ABI.
• File size of maintenance tool in offline installation is huge, see QTBUG-75267
  • It seems offline installation's maintenance tool contains whole installation package and that's why the size is big. Workaround: Use online installer instead

Windows

• 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.

Linux

• Building Qt modules fails with binaries delivered with online installer see bug QTBUG-52501. Workaround is to build whole Qt from source or have libicu 56 installed on the system.

macOS

• Building for iOS-simulator fails with Xcode 10.0, see QTBUG-71313
  • workaround: add QMAKE_IOS_DEPLOYMENT_TARGET=9.0 to the pro file, or to use an earlier Xcode version.

• Qt for Android known issues
• Qt Creator: Kits not set up when using NDK r18, see https://bugreports.qt.io/browse/QTCREATORBUG-21281
