How can I tell if my qml files are actually compiled in to my app?

[Rich v]

I suspect my qml files specified in the CMakeLists.txt for the app itself (not a separate qml module) are not getting into the qrc system. I've been converting Qt5-based code to work with Qt6 and in the process of converting from the old

qtquick_compiler_add_resources(RESOURCES myqrc.qrc)

to the equivalent

qt_add_qml_module()

call. However, while the previous method worked fine and the files ended up in the appropriate qrc:/qml/myFile.qml area, I have qml codegen errors when compiling the same files. Those files compile just fine with Qt5's CMake API.

I suspect that the codegen errors prevent inclusion of the compiled output in the qrc system.

Here's a sample of those errors:

Am I correct that these compile problems are preventing the various qml files from being accessible at runtime from the expected qrc:/MyApp/main.qml location? If so, why am I running into all these errors when the compile just fine with qtquick_compiler_add_resources()?

@Rich-v said in How can I tell if my qml files are actually compiled in to my app?:

to the equivalent
qt_add_qml_module()

since you said you are not building a module this is not the equivalent method

you might rather want this: https://doc.qt.io/qt-6/resources.html#build-system-integration

@raven-worx
The blog here [1] seemed to indicate that the main program was a module just as the "extra module" was a module. I'm just trying to offer justification for trying what I did. Here's what that blog prescribed:

qt_add_executable(main_program main.cpp)

qt_add_qml_module(main_program
    VERSION 1.0
    URI myProject
    QML_FILES
        main.qml
    SOURCES
        onething.cpp onething.h
)

It's also mentioned on the page you linked that qt_add_qml_module is an option:

Finally, qt_add_qml_module allows you to embed Qt Quick resources into the resource system of your application. The function is defined in the Qml component of the Qt6 CMake package.

I don't fully understand if the options listed at the URL you provided are all created equal or if there are only certain circumstances when you should use qt_add_qml_module.

Closing - files are in qrc system. Codegen errors are likely just due to some setting that is on a more sensitive setting.
