Install Qt#

Qt 5#

Creating prebuild version of Qt: For a working itom development environment only a prebuild version of Qt is necessary.

  • Install Qt into the ${MAINDIR}/3rdParty/Qt5.12.1 with the components

    msvc2017 64-bit, Qt WebView, Qt WebEngine. Qt Creator is not necessary, but can not be unchecked

  • After the installation copy the folder to another location

    (${MAINDIR}/3rdParty/Qt5.12.1_backup) and uninstall Qt in the Windows program settings

  • Rename Qt5.12.1_backup back to Qt5.12.1

  • From Qt5.12.1/Docs/Qt-5.12 copy all * .qch files (only in the main folder)

    to Qt5.12.1/5.12/msvc2017_64/doc

  • Start the Qt Assistant (${MAINDIR}/3rdParty/Qt5.12.1/5.12/msvc2017_64/bin),

    open options/documentation and delete all. Add then the copied documentation files.

  • From Qt5.12.1 delete the following things:

    • folder: dist, Examples, Tools, vcredist, Docs (after having copied the qch files)

    • files: all files in the main folder, e. g. components.xml…

  • Copy OpenSSL libeay32.dll and ssleay32.dll to the ${MAINDIR}/3rdParty/Qt5.12.1/5.12/msvc2017_64/bin

Warning

Create a path on your hard drive with a long, long path name (called ${MAINDIR}) (later, the all-in-one path on destination computers must be shorter than this path name, due to the Qt patching)

Warning

The QT version 5.6.2 has a bug which prevent the start of the QT designer {‘QTBUG-53984’: (’https://bugreports.qt.io/browse/QTBUG-53984’, ‘QTBUG-53984’)}. The workaround is to change the name of Qt5WebEngineWidgets.dll and Qt5WebEngineWidgetsd.dll, then copy the Qt5Core.dll and Qt5Cored.dll and change the name of these dll-files into Qt5WebEngineWidgets.dll and Qt5WebEngineWidgetsd.dll. This bug should be solved with QT version 5.6.3 (release August 2017).

Warning

Qt WebEngine, Qt WebEngineWidgets are only available under VS 2017 as it is shown in the figure below!

Qt 5.10.1 supports Qt WebEngine, Qt WebEngineWidgets for VS2015.
