Re-configuration of a Qt Quick project takes 6.5x the time as the initial configuration

    XMLWordPrintable

Details

    • macOS

    Description

      Given the AQtQuickApp.zipwhich is just a Qt Creator Qt Quick application that does a:

      foreach(number RANGE 0 500)
    qt_add_executable(appAQtQuickApp${number}
        main.cpp
    )

   # ...

endforeach()

      First configuration:

      [cmake] Elapsed time: 02:17.

      Then change something in the main.qml file and run cmake again:

      [cmake] Elapsed time: 10:17.

      Then build the project. On my MacBook Pro M3 took:

      [9519/9519 24.9/sec] Linking CXX executable appAQtQuickApp500.app/Contents/MacOS/appAQtQuickApp500
19:45:12: The command "/Applications/CMake.app/Contents/bin/cmake --build /Users/cristian/Projects/AQtQuickApp/build/Qt_6_9_0_for_macOS-Debug --target all" finished successfully.
19:45:12: Elapsed time: 06:22.

      Then change something in the main.qml file and run cmake again:

      [cmake] Elapsed time: 14:57.

      This has a huge potential of improvement!
