    Thanks, with MinGW, I managed to connect Mqtt from manually assembled libraries. Can you please tell me how to solve the issue with the compilation Android app?

      Please tell us first what issue it is...
      Did you build mqtt for Android?

        @jsulm First I needed to do it for a window application, I did it, now I need to connect mqtt to a mobile application but there is aarch64-v8 architecture so compilation does not work.

          Just build it using Android NDK or your Android Kit in QtCreator.

          And please, "does not work" does not tell anything. You should say what you tried and what happened.

                                      @Sergey_85 Not sure why it is not working try:

                                      export Qt6_DIR=/home/ph/opt/Qt/6.8.1/android_arm64_v8a/lib/cmake/Qt6
                                      

                                      before calling cmake.
