    @JiujiuTong "-sysroot ~/raspi/sysroot" - does ~/raspi/sysroot contain file libpthread.so ?

        @JiujiuTong My question was: does it contain that file?

            @JiujiuTong Can you do:

            file PATH_TO/libpthread.so
            

            and post the output?

              sorry for my late reply
              these days i have been rework the job. just following the steps again.
              now there is another error :
              /usr/include/math.h:31: error: bits/math-vector.h: No such file or directory
              #include <bits/math-vector.h>
              i try to find the file bits/math-vector.h ,but there is no such file
              and i searched that is should be included in libc6-dev package.
              but i have installed the latest package , but still no such file
              is there any other ways to fix it? thank you very much !

                @jsulm it seems that the qtcreator do not using the files specified by sysroot(~/rapi/sysroot/usr/include/math.h), it is using files on host files /usr/include/math, how can i use the files under sysroot ?thank you !

                  @JiujiuTong How did you configure the kit in QtCreator? If it is set up correctly then it should work.

                    i think the configure is correct, i am following the steps :
                    http://wiki.qt.io/RaspberryPi2EGLFS
                    first create device ,then configure compiler,debug, and Qtversion. Go to Options -> Build & Run with sysroot path selected.
                    i add the absolute path in the project, then it seem ok now with one problem:
                    https://forum.qt.io/topic/77854/error-undefined-reference-to-std-__throw_out_of_range_fmt-char-const-glibcxx_3-4-20/3
                    can you help me?

                            關於這個錯誤:
                            /home/tong/raspi/qt5pi/lib/libQt5MultimediaWidgets.so: undefined reference to QGLContext::currentContext()@Qt_5'
                            ....
                            ...

                            我是加入:
                            .pro:
                            QT += opengl

                            才解決此問題的

                            會加 qt += opengl 是因為 QGLContext::currentContext() ...etc 來自於 opengl
                            我覺得這 error 是因為 Qt5MultimediaWidgets 於 Embedded 時,會去呼叫 opengl 方法的關係

                            希望對你有幫助。

                                I am also getting the error when i try to cross compile qt in raspberry pi 2 without x11.
                                When i am running console application it is running.
                                But when i am using widget application in pi touchscreen it is showing
                                "Unable to query physical screen size, defaulting to 100 dpi.
                                To override, set QT_QPA_EGLFS_PHYSICAL_WIDTH and QT_QPA_EGLFS_PHYSICAL_HEIGHT (in millimeters)."
                                and the system is idle
                                can anyone help me with this

                                when i am debugging the output in qtcreator is as follows
