My built and deployed Qt application does not start.

k_miya

After building and deploying the executable file, nothing happened when I ran it.
Even when launching the executable file from the command prompt, nothing happened.

When I redirected the standard output after execution to a file,
only the output from C++'s std::cout was recorded.

I built and deployed the Qt application in the following environment.
(Since Qt installed via vcpkg did not work properly, I am using Qt installed via the Qt installer.)

OS: windows 11
Compiler : cl
terminal : Developer Command Prompt for VS 2022 (x64)
Build System : CMake 3.22
Generator : Ninja 1.13.1
Qt version : 6.9.3

The source code is reused from Qt Academy courses.

The build procedure is as follows:

Launch Developer Command Prompt for VS 2022 (x64).
cmake configure

cmake --preset msvc-x64-debug

cmake build and install

cmake --build build\debug --target install

Launching the Executable File

Launch the executable file from the following path using the Command Prompt.

> install\debug\bin\appqml-cpp-example.exe

# Nothing happens and it ends.

When I attempted to redirect to a file, only the following was output.

> install\debug\bin\appqml-cpp-example.exe > log.txt 2>&1

# log.txt
--- Standard C++ main() started ---

With windeployqt there is a utility with the installation of Qt to help deploying apps. There is no need to write an own deployment script. The documentation for the usage of the windeployqt tool can be found at https://doc.qt.io/qt-6/windows-deployment.html

Bonnie

@Wladimir-Leuschner Well, actually qt_generate_deploy_qml_app_script in cmake will automatically call windeployqt.

@k_miya You can also post your cmake build output, it should show how windeployqt runs and what files it copies.

@k_miya said in My built and deployed Qt application does not start.:

When I attempted to redirect to a file, only the following was output.

This doesn't prove the application does not start. Default qDebug in a Qt GUI application does not write to stdout/stderr so even the application runs normally you won't see them in the log, only cout lines will.

[Added]
I just tried your main.cpp and CMakeLists.txt, this line is the problem

qt_policy(SET QTP0001 NEW)

I don't know why but it seems to disable the qrc system and make the qml can't be read by the application.
You should find something that can start and debug an application, for example I use QtCreator to do that, if you haven't installed it you can also use WinDbg.
I start the exe by QtCreator or WinDbg and can see output telling me the qml cannot be found.

@Wladimir-Leuschner
Thank you for your post.
I agree with what @Bonnie is saying.

I would like to avoid running windeploy manually and just execute the cmake command.
I used the following article as a reference for the qt_generate_deploy_qml_app_script in CMakeLists.txt.
https://www.qt.io/blog/cmake-deployment-api

@Bonnie
Thank you for actually trying out the code.

qt_policy(SET QTP0001 NEW)

When I ran the command cmake --preset msvc-x64-debug,
a warning message appeared, so I added this line to CMakeLists.txt to suppress it.
I will comment out the relevant section in CMakeLists.txt and try building and deploying.

I used vscode to write the code, but I would also like to try Qt Creator.

@Bonnie said in My built and deployed Qt application does not start.:

this line is the problem

qt_policy(SET QTP0001 NEW)

I don't know why but it seems to disable the qrc system and make the qml can't be read by the application.

That policy doesn't disable the qrc system. Rather, it puts QML modules under a new standard location (described at https://www.qt.io/blog/whats-new-for-qml-modules-in-6.5 )

@k_miya said in My built and deployed Qt application does not start.:

    const QUrl url(u"qrc:/QmlCppExample/main.qml"_qs);

With the QTP0001 policy, the URL is now qrc:/qt/qml/QmlCppExample/main.qml.

a warning message appeared, so I added this line to CMakeLists.txt to suppress it.
I will comment out the relevant section in CMakeLists.txt and try building and deploying.

The current recommended approach is:

Change qt_standard_project_setup() to qt_standard_project_setup(6.5) (this has the same effect as writing "qt_policy(SET QTP0001 NEW)")
Rename the file from main.qml to Main.qml ('m' -> 'M')
Replace engine.load(url); with engine.loadFromModule("QmlCppExample", "Main"); (so that you only need to know the module name, you don't need to know the URL)

k_miya

I made the following changes to each file:

CMakeLists.txt

Deleted qt_policy(SET QTP0001 NEW)
Added REQUIRES 6.5 to the qt_standard_project_setup argument

main.cpp

Added using namespace Qt::Literals::StringLiterals; after include.
Changed url(u"qrc:/QmlCppExample/main.qml"_qs) to url("qrc:/qt/qml/QmlCppExample/main.qml"_s)
- For this, I referred to the following: https://www.qt.io/blog/whats-new-for-qml-modules-in-6.5
