I want to see map with cmake, qml. But it's not working

Hi for all!

I'm new to Qt so I think i'm losing something. But i don't know what's missing..

I'm using Qt 5.15.2 with MSVC 2019 64-bit, Windows 11

My CMakeLists.txt is

cmake_minimum_required(VERSION 3.16)
project(Foo VERSION 0.1 LANGUAGES CXX)

set(CMAKE_INCLUDE_CURRENT_DIR ON)
set(CMAKE_AUTOUIC ON)
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)
set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

set(PROJECT_DIR ${CMAKE_CURRENT_SOURCE_DIR})
set(PROJECT "FOO")

set(QML_IMPORT_PATH "C:/Qt/5.15.2/msvc2019_64/qml")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${Qt5Widgets_EXECUTABLE_COMPILE_FLAGS}")
set(CMAKE_PREFIX_PATH "C:/Qt/5.15.2/msvc2019_64/lib/cmake")

set(RESOURCES
    Resources.qrc
)

set(qml_resource_files
    "map.qml"
)

find_package(Qt5 COMPONENTS Core Gui Qml Quick Widgets QuickWidgets Network Positioning Location OpenGL Sql REQUIRED)
find_package(QT NAMES Qt6 Qt5 COMPONENTS Widgets REQUIRED)

file(GLOB PROJECT_SOURCES
    "main.cpp"
    "Qml/*.qml"
    "*.qrc"
    "MainWindow.h"
    "MainWindow.cpp"
    "MainWindow.ui"
)
qt5_add_resources(QT_RESOURCES Resource.qrc)

target_link_libraries(Foo PRIVATE
    Qt5::Core Qt5::Quick Qt5::QuickWidgets Qt5::Gui
    Qt5::Qml Qt5::Widgets Qt5::Positioning Qt5::Network Qt5::Location Qt5::Sql Qt5::OpenGL
)
...
...

My MainWindow.cpp is

Foo::Foo(QWidget *parent)
    : Foo(parent)
    , ui(new Ui::Foo)
{
    ui->setupUi(this);    
    QWidget* mapWidget = ui->centralwidget->findChild<QWidget*>("mapWidget");    
    QQmlEngine* engine = new QQmlEngine(this);    
    engine->addImportPath("C:/Qt/5.15.2/msvc2019_64/qml");    
    engine->addImportPath("C:/Qt/5.15.2/msvc2019_64/plugins");
    
    mapView = new QQuickWidget(engine, mapWidget);
    QQmlContext* context = engine->rootContext();
    mapView->setSource(QUrl(QStringLiteral("qrc:/Qml/map.qml")));

And for the last, my map.qml is

import QtQuick 2.15
import QtPositioning 5.15
import QtLocation 5.15
import QtQuick.Controls 2.15

Item {
    id: mapItem
    Map {
        id: mapControl
        plugin: Plugin {
            id: mapPlugin
            name: "mapboxgl"
            PluginParameter {
                name: "mapboxgl.access_token"
                value: <My Token Here>
            }
        }
        activeMapType: mapControl.supportedMapTypes[1]
    }
}

Screen is just white and showing nothing but the output is below

16:03:04: Starting <elision>\build.x64\Debug\Foo.exe...
1 , "The geoservices provider is not supported."
qrc:/Qml/map.qml:18:9: Unable to assign [undefined] to QDeclarativeGeoMapType*

Any help please !

Hi and welcome to devnet,

Surprisingly, the documentation only mentions MinGW for Windows. Did you try it ?

Hi @SGaist

Thank you for replying !!

After changing MSVC to MinGW and CMakeLists.txt,

I got following log message.

How can I solve it ??

10:03:59: Starting C:\Users\user\Desktop\untitled\build\Desktop_Qt_5_15_2_MinGW_64_bit-Debug\untitled.exe...
QObject::connect(QQuickWindow, QDeclarativeGeoMap): invalid nullptr parameter
10:04:01: C:\Users\user\Desktop\untitled\build\Desktop_Qt_5_15_2_MinGW_64_bit-Debug\untitled.exe exited with code 0

MinGW perfectly works now !!!!

If anyone moving MSVC->MinGW you should check project cmake's "Current Configuration". which would be set to C:/Qt/5.15.2/msvc2019_64/ ~~~.

It must be changed to C:/Qt/5.15.2/mingw81_64/~~~

And in QML file, Map field should have "achors.fill: parent"

All fixed well. super thanks to @SGaist you saved my life
