    @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 Try with a clean build folder (best to create a fresh one)

                                  @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.

                                    everything is the same, under gcc-64 everything was assembled without problems and works, I don’t understand why there are such difficulties here
