    I was using Qt 5.15 and could easily add ROS2 to my applications, but since I switched to Qt6, I cannot transfer ROS2 to the system.

      What is your question?

      If debugging is the process of removing software bugs, then programming must be the process of putting them in.

        The problem is that it works fine when I compile it with QT5.15

        e8d43186-9bbe-40c3-a3e4-4e1b2d0c5d0a-image.png

        Easily communicates with ROS2

        When I compile the same code with QT6, I get the following errors:

        60f4dc9f-a54f-489e-977d-f2a3b363d6d6-image.png

        There are 240 errors similar to these errors.

        Note:
        ROS2 (Robot Operating System 2) is a flexible framework for writing robot software. It is the next-generation version of the original ROS (Robot Operating System) and is designed to address the limitations of ROS 1, offering more robust, scalable, and real-time capabilities. ROS 2 enables the development of robot applications that can run on various hardware platforms, from small embedded devices to large, complex robots.

          @serkan_tr What compiler is used when you're building for Qt6? And what compiler was used for Qt5?

            @jsulm I use the same compiler in both.

                    from what I can see ROS2 should be an externally linked library, so nothing should have changed by simply switching Qt5 with Qt6, if you didn't change anything else in your project file.

                    Can you actually compile a simple Qt6 program and if that works link it against ros2 ?

                    actually strike that:

                    https://docs.ros.org/en/foxy/Installation/Alternatives/Windows-Development-Setup.html

                    It's based on Qt5 so you can't simply switch to Qt6 yourself and expect it to work. Qt6 broke compatibility with Qt5.
                    You would probably have to change the ros2 sourcecode where needed and if possible.

                      @J-Hilk I tried this and added it to a very simple program, but even just adding the library causes Qt6 to give these errors.

                        @serkan_tr like I said, you're trying to compile a program/library that is written for Qt5 with Qt6 libraries that won't work.

                        Either fix/rewrite the ros2 code or compile it as a dll with Qt5 and and use it that way
