一、参考文档：

    . Qt5..0编译移植到Linux-Arm-A9

        https://my.oschina.net/u/938455/blog/474516

    . qt-5.6. 移植之qt源码编译

        http://www.cnblogs.com/chenfulin5/p/5798764.html

    . qt-5.6. 移植之tslib 配置及编译

        http://www.cnblogs.com/chenfulin5/p/5801604.html

二、compiler configure

    export PATH=$PATH:/home/zengjf/zengjfos/output/host/opt/ext-toolchain/bin:

三、compile tslib 1.4

    ./autogen.sh

    echo "ac_cv_func_malloc_0_nonnull=yes" >arm-linux.cache

    ./configure --host=arm-linux --prefix=`pwd`/_install CC=arm-none-linux-gnueabi-gcc --cache-file=arm-linux.cache

    make && make install

四、compile Qt 5.8

    . cat qtbase/mkspecs/linux-arm-none-gnueabi-g++/qmake.conf

        #

        # qmake configuration for building with arm-linux-gnueabi-g++

        #

        MAKEFILE_GENERATOR      = UNIX

        CONFIG                 += incremental

        QMAKE_INCREMENTAL_STYLE = sublib

        include(../common/linux.conf)

        include(../common/gcc-base-unix.conf)

        include(../common/g++-unix.conf)

        # modifications to g++.conf

        # arm-none-linux-gnueabi-g++

        QMAKE_CC                = arm-none-linux-gnueabi-gcc

        QMAKE_CXX               = arm-none-linux-gnueabi-g++

        QMAKE_LINK              = arm-none-linux-gnueabi-g++

        QMAKE_LINK_SHLIB        = arm-none-linux-gnueabi-g++

        # modifications to linux.conf

        QMAKE_AR                = arm-none-linux-gnueabi-ar cqs

        QMAKE_OBJCOPY           = arm-none-linux-gnueabi-objcopy

        QMAKE_NM                = arm-none-linux-gnueabi-nm -P

        QMAKE_STRIP             = arm-none-linux-gnueabi-strip

        load(qt_config)

    . ./configure -release \

        -opensource \

        -confirm-license \

        -xplatform linux-arm-none-gnueabi-g++ \

        -prefix /home/zengjf/zengjfos/Qt5./QtLibOut \

        -nomake examples \

        -no-opengl \

        -no-iconv \

        -silent \

        -qpa linuxfb \

        -no-gtk \

        -qt-libjpeg \

        -qt-libpng \

        -tslib \

        -I/home/zengjf/zengjfos/Qt5./tslib-1.4/_install/include \

        -L/home/zengjf/zengjfos/Qt5./tslib-1.4/_install/lib

五、lib使用环境变量：

    . 拷贝前面编译的lib库到ARM文件系统中；

    . 配置lib库环境变量：

        # tslib and qt configure                                                                  

        export TSLIBDIR=/usr/share/tslib

        export TSLIB_CONSOLEDEVICE=none

        export TSLIB_FBDEVICE=/dev/fb0

        export TSLIB_TSDEVICE=/dev/input/event0

        export TSLIB_CONFFILE=$TSLIBDIR/etc/ts.conf

        export TSLIB_PLUGINDIR=$TSLIBDIR/lib/ts

        export TSLIB_CALIBFILE=/etc/pointercal                                           

        export QTDIR=/usr/share/qt

        export QT_QPA_PLATFORM_PLUGIN_PATH=$QTDIR/plugins

        export QT_QPA_PLATFORM=linuxfb:tty=/dev/fb0

        export QT_QPA_FONTDIR=$QTDIR/lib/fonts

        export QT_QPA_GENERIC_PLUGINS=tslib:$TSLIB_TSDEVICE                             

        export QT_DEBUG_PLUGINS=

        export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/lib:/usr/lib:$TSLIBDIR/lib:$QTDIR/lib

        export PATH=$PATH:/usr/bin:$TSLIBDIR/bin:/usr/sbin:/bin
