    @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
                      Debugging starts
                      Listening on port 10000
                      Remote debugging from host 192.168.15.153
                      Process /home/pi/qtinpitry created; pid = 8079
                      File transfers from remote targets can be slow. Use "set sysroot" to access files locally instead.
                      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).

                      can anyone help me.
                      Thanks in advance
