    @JiujiuTong You can try to build those libraries manually:

    cd poly2tri
    /home/pi/opt/qt-everywhere-opensource-src-5.7.1/qtbase/bin/qmake /home/pi/opt/qt-everywhere-opensource-src-5.7.1/qtlocation/src/3rdparty/poly2tri/poly2tri.pro -qtconf /home/pi/opt/qt-everywhere-opensource-src-5.7.1/qtbase/bin/qt.conf -o Makefile
    

    then make and make install

    after i've create the archives(libclip2tri.a, libclipper.a,libpoly2tri.a ) ,then copy them to /usr/lib
    and restart the QT configuer and make then make install, is it right ?

      @JiujiuTong *.a are static libraries, those are usually not in /usr/lib as they are only needed during linking, but you can try.
      Actually you should copy them to the directory where you want to install your Qt.

            @JiujiuTong In the description how to build Qt for RPi they use this for device: -device linux-rasp-pi-g++
            You use -device linux-pi3-g++.
            -march=armv8-a -mtune=cortex-a53 - this does not look correct for RPi.
            Please try with -device linux-rasp-pi-g++

                  well, actually i have tried both with linux-rasp-pi-g++ /linux-pi3-g++.
                  maybe i should try with linux-rasp-pi2-g++. life is so tough.....
                  thank you !

                    an interesting thing is that i following the steps:
                    http://wiki.qt.io/Native_Build_of_Qt5_on_a_Raspberry_Pi
                    it is ok now , the problem is that source code for git is same with the release code ?
                    can i use it for programming ?

                      @JiujiuTong It depends which branch/tag from Git you use. For each release there is a branch.

                          @JiujiuTong What do you mean by "installation process"? The "release code" is what you can find in the release branch in Git.

                            i mean the "make install" process,
                            it only takes more than two minutes
                            is the branch code same with the code download from qt (e.g. qt-everywhere-opensource-src-5.7.1.tar.gz)?

                                the "make" process only take more than 2 minutes too, the configure process is very long about 7 hours ... no error information

                                  @JiujiuTong configure takes 7 hours? And make only 2 minutes?! You're doing something wrong. Are you sure make step was successful?

                                    yes, many make output: nothing to be done for "first"
                                    no error infors
                                    the interesting thing is:
                                    the configure output summary :
                                    building on : linux-g++ (arm ,cpu features: none detected)
                                    building for :devices/linux-rpi3-g++ (arm, cpu features: neon)
                                    so i thing -device linux-rpi3-g++ option is correct,
                                    the steps on http://wiki.qt.io/Native_Build_of_Qt_5.4.1_on_a_Raspberry_Pi
                                    may have missing some critical steps or my ENV is not right

                                          i finished the installation, how to know it is built successfully,
                                          i have install qt-creator(qt5.3.2), i remove it and link the /usr/bin/qmake to the /usr/local/qt5/bin/qmake,
                                          current qmake -v show the correct version info.
                                          how to know the qt5.7 is correct installed on rp3? thank you !
