QtCreator cannot build main.qml file, an example qml from a book!

Axel Spoerl

What is wrong?

Please show the main.qml file here. Without some more information, it's hard to say. Could be anything from a broken compile kit, wrong Qt version, broken example from the book.

@jdent the main.qml is

/* This file is generated and only relevant for integrating the project into a Qt 6 and cmake based
C++ project. */
import QtQuick
import QtQuick.Controls

ApplicationWindow {
    visible: true
    width: 640
    height: 480
    title: qsTr("Hello QML")

    menuBar: MenuBar {
        Menu {
            title: qsTr("File")
            MenuItem {
                text: qsTr("Exit")
                shortCut: "Ctrl+Q"
                onTriggered: Qt.quit()
            }
        }
    }

    Text {
        id: hw
        text: qsTr("Hello World")
        font.capitalization: Font.AllUppercase
        anchors.centerIn: parent
    }

    Label {
        anchors { bottom: hw.top; bottomMargin: 5; horizontalCenter: hw.horizontalCenter }
        text: qsTr("Hello Qt Quick")
    }
}

And the kit I believe its broken

@jdent The build settings has the CMAKE_GENERATOR as Ninja and it appears as red ; I don't know what it should be??

jdent

@jdent I don't know the version of the QtQuick and QtQuick.Controls - I installed 6.6.2. where can I find the version? Could that be the culprit?

Hi Jdnet,

Did you try to look at general messages tab. If you have no sufficient information on issues tab you can find it on general messages maybe you can find the exact issue over there.

Axel Spoerl

@jdent
If you believe your kit is broken, there should be a warning / error icon in front of the kit name in Creator. If you hover over this icon, you will get the reason for the error / warning.

@Axel-Spoerl

I have some kits with warnings but that should not matter because I am using the default Desktop kit correct?

Axel Spoerl

@jdent The broken ones are your Android kits. But I reckon, you want to compile for Windows?
That should work.
Please do a fresh configureand ninjafrom the command line.
What does it say?

jdent

@Axel-Spoerl you mean like this:

U:\Qt\Tools\Ninja>ninja
ninja: error: loading 'build.ninja': The system cannot find the file specified.

where is configure.exe ?

Axel Spoerl

@jdent
Well, that's a path issue.
You have to configure the PATH environment variable in your system settings and make it point to the ninja executable in the Qt installation tree.
Same is needed for CMake.

configure.batis in your source tree.

jdent

@Axel-Spoerl I set the PATH environment to point to Ninja.exe, and now I can run Ninja anywhere. But where should I run it from?
The only folder with build.ninja is in U:\Qt\6.6.2\Src\qtwebengine\src\3rdparty\chromium\tools\memory\partition_allocator\palloc_viewer
and
U:\Qt\6.6.2\Src\qtwebengine\src\3rdparty\ninja\misc\afl-fuzz

and configure is a batch file in U:\Qt\6.6.2\Src

Is it safe to run these files?

Axel Spoerl

@jdent
If build.ninja isn’t found, configure hasn’t been run or hasn’t finished properly. I’ll not say whether configure.bat is safe on your system. If you have cloned Qt from a recent, safe source and not made any modifications, it should be.

@Axel-Spoerl I don't think @jdent wants to build Qt here.

It' that his Qt example doesn't compile with his setup.

@jdent can you try a shorter path for your example? There are issues on Windows with Qt Design Studio projects and long project paths.

jdent

@cristian-adam My path is already small since QT root is at U:\Qt
How would I move the example to a shorter directory?

You are correct I am not building source but an example

Please help!

cristian-adam

@jdent U:\Users\Juan Dent\Qt\with QtCreator\build-QtQuickApp-Desktop_Qt_6_6_2_MSVC2019_64bit-Debug_deps is a bit long.

Have a look at https://bugreports.qt.io/browse/QTBUG-117413
and if you are building a Qt Design Studio project change the corresponding CMake code like this:

if (BUILD_QDS_COMPONENTS)
    if (WIN32)
        set(FETCHCONTENT_BASE_DIR $ENV{HOMEDRIVE}/bld/qds-deps) # <---- new line
    endif()
    include(${CMAKE_CURRENT_SOURCE_DIR}/qmlcomponents)
endif()
