      IIRC, you should also have one on your computer in /usr/local/qt5pi, use that one

        Thanks. This solved my problem. .I approached the end and I have another problem now I'm glad if you help some more. I made all the adjustments on qt creator. when I was run the app I get the following error;

        :-1: error: Compiler /home/sefa/rsp/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-g++ not found. Check the value of CROSS_COMPILE -device-option

          As silly as it may sound, is the file there ?

            No such directory as /home/sefa/rsp.... This is my previous trying. Although I show the directory for the compiler as /home/sefa/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-g++. I get error that /home/sefa/rsp/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-g++ not found. Check the value of CROSS_COMPILE -device-option.

            I do not understand why there is such.

              You moved it after having compiled Qt ?

                Ok I solved this issue by mkdir /home/sefa/rsp.. and copy past the compiler here. What about Unknown module(s) in QT: quick. This problem probably stems from this, at the end of the document said, go to the “Rasperry Pi” kit tab->System Environment and add LD_LIBRARY_PATH which is set to /usr/local/qt5pi/lib. But I do not know how to do it?

                  Before modifying anything, did you compile/install that module ?

                    I have a qtquick1 file. And I run the following string in this file.
                    /usr/local/qt5pi/bin/qmake .
                    make -j 4
                    sudo make install

                      You need to build the qtdeclarative module. qtquick1 is for the version of 1

                        When I compiled qtdeclarative I get the following error.

                        make[2]: Entering directory /home/sefa/opt/qt5/qtdeclarative/src/qmldevtools' make[2]: *** No rule to make target /mnt/rasp-pi-rootfs/usr/local/qt5pi/include/QtCore/qglobal.h', needed by .obj/qqmljsast.o'.

                          Did you mount your Raspberry Pi root filesystem before building ?

                            Yes I did. Also I get another error when make app without using qtquick as;

                            error: error trying to exec 'cc1plus': execvp: No such file or directory

                              SGasist, Is there something you think about this issue ?

                                Did you move anything around like your compiler folder ?

                                    Then clean the module and call qmake again with your Rasberry Pie root filesystem mounted
