    @jsulm
    i run the app from terminal as you suggested with set(QT_DEBUG_PLUGINS 1) flag in my project CMakeList.txt , but it show the same output in terminal like in Qt Creator output window:

    qt.qpa.plugin: Could not find the Qt platform plugin "wayland" in ""
    qt.qpa.plugin: Could not find the Qt platform plugin "xcb" in ""
    

    Is it correct way to set the debug info on plugins like i did: set(QT_DEBUG_PLUGINS 1)?

      Ok, i hope that i correctly understand you, i added this line to Run settings environment in Qt Creator: QT_DEBUG_PLUGINS=1

      After i run the project again and i've got the additional string of information in my project output window in Qt Creator:

      qt.core.plugin.factoryloader: ignoring "org.qt-project.Qt.QPA.QPlatformIntegrationFactoryInterface.5.3" since plugins are disabled in static builds
      

      What does it mean?

      By the way my environment is:

      1. Qt Creator 13
      2. Qt 6.7.0 (static build)
      3. Ubuntu 24.04 LTS

        @al072072 Just realized that the plug-ins were not found. My suggestion was for cases where plug-ins are found but fail to load, so useless for your problem.

        The error messages in your first post clearly say that these plug-ins where not found. Check whether they were built (configure script says what is enabled and what not).

        Also, do you really need a static Qt build?

        This is not enough:

        sudo apt install libxcb-xinerama0
        sudo apt install qt6-wayland
        

        you also need the dev packages.

          I am sure this plugins (xcb,wayland) were not built becase i checked the plugins platfroms folder and there is no plugins files inside of it. I am not sure about the static build (just want to set it up like in my windows project) and run it as a static (there is no problems with dynamic build). Thank you for information i will try to find a dev libs and install them. What should i do after installing the dev libs? It seems like i need to rebuild the Qt library, is it possible to force disabling the plugins use during the build configuration process? I already tried -skip xcb and -skip wayland, but it didn't help still got the errors when Run the app.

            Well, for graphical Qt applications you need at least one backend. On Linux usually xcb or wayland. So, first decide what you need and then disable what you do not need.
            "but it didn't help still got the errors when Run the app" - of course, how should your app run without any backend?

              i also tried to make a configuration without skipping both of (xcb and wayland) - the same result. I've checked the dev packages for :

              sudo apt install libxcb-xinerama0-dev
              sudo apt install qt6-wayland-dev
              

              packages are installed.

              Now i reconfigure the build with the following configuration string:

              ./configure -release -static -static-runtime -opensource -confirm-license -nomake examples -nomake tests -prefix /home/Qt/6.7.0/static_gcc_64
              

              Here is configuration output:

              Qt is now configured for building. Just run 'cmake --build . --parallel'

              Could you please take a look on it and advice me to do any additional steps for configuration that i will be able to run the static version of app after build? thank you

                @jsulm
                i also tried to make a configuration without skipping both of (xcb and wayland) - the same result. I've checked the dev packages for :

                sudo apt install libxcb-xinerama0-dev
                sudo apt install qt6-wayland-dev
                

                packages are installed.

                Now i reconfigure the build with the following configuration string:

                ./configure -release -static -static-runtime -opensource -confirm-license -nomake examples -nomake tests -prefix /home/Qt/6.7.0/static_gcc_64
                

                Here is configuration output:

                Could you please take a look on it and advice me to do any additional steps for configuration that i will be able to run the static version of app after build? thank you

                    @al072072 Look into config.log file which is generated by configure script - you will find exact information about missing libs.
