c++/QML issues with CMake setup generated by QtCreator

FredJupiter

Hi Everyone,
I'm currently struggeling with the idea behind the automatic C++/QML registration. I've implemented a simple example C++ object like described here:

https://doc.qt.io/qt-6.2/qtqml-cppintegration-topic.html

The generated moc code isn't finding my header file, which is at the same level as the main.cpp.

Could someone be so kind and point me into the right direction? Do I have to move the C++ class into a special named folder?

Thanks and Best Fred

Hi,

Are you using qmake or CMake ?
Can you show your project file content ?

FredJupiter

@SGaist I'm using CMake.

cmake_minimum_required(VERSION 3.21.1)

option(LINK_INSIGHT "Link Qt Insight Tracker library" ON)
option(BUILD_QDS_COMPONENTS "Build design studio components" ON)

project(testAppApp LANGUAGES CXX)

set(CMAKE_AUTOMOC ON)

find_package(Qt6 6.2 REQUIRED COMPONENTS Core Gui Qml Quick)

if (Qt6_VERSION VERSION_GREATER_EQUAL 6.3)
    qt_standard_project_setup()
endif()

qt_add_executable(testAppApp src/main.cpp
    src/theorb.h src/theorb.cpp)

qt_add_resources(testAppApp "configuration"
    PREFIX "/"
    FILES
        qtquickcontrols2.conf
)

target_link_libraries(testAppApp PRIVATE
    Qt6::Core
    Qt6::Gui
    Qt6::Qml
    Qt6::Quick
)

if (BUILD_QDS_COMPONENTS)
    include(${CMAKE_CURRENT_SOURCE_DIR}/qmlcomponents)
endif()

include(${CMAKE_CURRENT_SOURCE_DIR}/qmlmodules)
include_directories(${CMAKE_SOURCE_DIR}/src)   #added by myself

if (LINK_INSIGHT)
    include(${CMAKE_CURRENT_SOURCE_DIR}/insight)
endif ()

include(GNUInstallDirs)
install(TARGETS testAppApp
    BUNDLE DESTINATION .
    LIBRARY DESTINATION ${CMAKE_INSTALL_LIBDIR}
    RUNTIME DESTINATION ${CMAKE_INSTALL_BINDIR}
)

I've added the include ./src by myself. This is working but without it the generated QML type registration code is compaining about the include file:

Looks like you are working with Qt Design Studio rather than Qt Creator, aren't you ?

@SGaist

I'm using the Qt Creator build on my machine some weeks ago...

@FredJupiter Is there a reason why you're using a beta version of Qt creator?

FredJupiter

@jsulm Not really, which branch do you suggest and think is working for sure?

@FredJupiter The current stable for example
