All platforms
- Check that your system meets Qt's requirements
- All open issues can be found from Jira: https://bugreports.qt.io
- 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.
- Qt Creator crashes when too many old Qt versions are installed, see QTCREATORBUG-21278
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.
- QTCREATORBUG-21278: Qt Creator crashes when too many old Qt versions are installed
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.
