car_interface.h missing from D-Bus Car Example

[rcx11]

I'm looking at the D-Bus example Remote Controled Car example. I'm trying to study the code to gain an understanding of its functioning. The controller.h file provided at code.qt.io contains the line #include "car_interface.h" which is not anywhere in the directory. I presume that's another class that's supposed to be there. The files in the Fedora package for Qt6 D-Bus examples match code.qt.io. Where are the missing file(s)?

So I think car_interface.h should be generated during building.

Or more correctly, generated during CMake's generation of the build system, as documented here.

@rcx11, have you run CMake on the remotecontrolledcar directory?

I know nothing about dbus. But since this is in the CMakeLists.txt:

qt_add_dbus_interface(controller_SRCS
../common/car.xml
car_interface
)

So I think car_interface.h should be generated during building.

I apologize for the late response. I did not try to run CMake on the directory. I still haven't, but after seeing your reply, that's most likely the issue. I appreciate your time. My project that might have used DBus is progressing in a direction that it won't be necessary, so I didn't look closer.

@rcx11 it uses a similar approach to gRPC/QtRemoteObjects in that the files that are compiled are generated using calls to the generators via cmake.

I checked Qt6.10.0 on windows 11 and indeed, until you configure the file cannot be found:

The file that generated (for reference of others reading this thread):

I'd recommend marking as resolved with @Paul-Colby 's response.
