    @JiujiuTong How are you building? Can you show your configure call? Does your sysroot contain all needed libraries?

    i,m using cross compile,and my configure is :
    ./configure -release -opengl es2 -skip webengine -device linux-rasp-pi2-g++
    -device-option CROSS_COMPILE=~/raspi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin/arm-linux-gnueabihf-
    -sysroot ~/raspi/sysroot -opensource -confirm-license -make libs
    -prefix /usr/local/qt5pi -extprefix ~/raspi/qt5pi -hostprefix ~/raspi/qt5 -v

    and i sysroot all the directory under raspi with "./sysroot-relativelinks.py sysroot"

      @JiujiuTong said in Qt on rpi3 , debug info ,how to fix?:

      ~/raspi/sysroot

      Did you check that your sysroot really contains what is needed (for example ~/raspi/sysroot/usr/lib)?

        i really don't know what libs are needed, so i do not check the Dir, the folder is created by :
        mkdir sysroot sysroot/usr sysroot/opt
        rsync -avz pi@raspberrypi.local:/lib sysroot
        rsync -avz pi@raspberrypi.local:/usr/include sysroot/usr
        rsync -avz pi@raspberrypi.local:/usr/lib sysroot/usr
        rsync -avz pi@raspberrypi.local:/opt/vc sysroot/opt
        and i checked that the output is right with no error.

          @JiujiuTong Maybe you should try to call configure from a clean Qt source directory? Did you try to build Qt before for x86? Even better would be to do out of source build see http://stackoverflow.com/questions/1245011/how-to-build-qt-out-of-source

            i confirm the source file is clean ,it is download from QT. i have built the QT under windows and centos x64, but not for x86.

              @JiujiuTong What I mean with this "Did you try to build Qt before for x86?" is - did you build for x86 OR x86_64 before from the SAME source code tree? Because currently you're linking against your host libraries.

                and i have tried to start a simple qt application(just a page with nothing showed ). it works well .
                the source file is clean every time i try to build the QT, i will delete the source file and extract it from source file.

                    I dont´t know if you still have the debugging problem but to answer to your first post:

                    The qt libraries for rpi are written to the qt5pi directory, outside of the rsynced sysroot.
                    The debugger is looking in the local sysroot directory for the libraries if you debug remote targets.
                    So just tell gdb to load the libraries of your project from the debugging target.
                    In Qt Creator go to Options->Debugger GDB-Tab an insert set sysroot target:/ in "Additional Startup Commands"

                      @sneubert
                      thank you for your answer!
                      should I just insert "set sysroot target:/" in "Additional Startup Commands" or replace string with my ENV value?
                      I can understand you description, but confused with "set sysroot target:/" i have set sysroot to "/home/tong/rasp/sysroot" in build&run -->kits-->sysroot. should the target:/ be the real path or something? thank you very much!

                        Leave you sysroot path in build&run --> kit --> sysroot the way it is, because this is needed for building your application. The set sysroot command I told you is just for gdb to instruct loading libraries remote. Use the exact string set sysroot target:/ only for "Additional Startup Commands" in Options->Debugger GDB-Tab.

                              @JiujiuTong As I said "skipping incompatible" message means that the library is build for a different architecture. You're most probably mixing architectures.
                              /usr/lib/libpthread.so - this looks like a path on your host PC. You cannot use libraries from your host PC (X86_64) to cross compile for ARM.
