一、参考文档：
    1. Qt5.7.0编译移植到Linux-Arm-A9
        https://my.oschina.net/u/938455/blog/474516
    2. qt-5.6.0 移植之qt源码编译
        http://www.cnblogs.com/chenfulin5/p/5798764.html
    3. qt-5.6.0 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
    1. 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)

    2. ./configure -release \
        -opensource \
        -confirm-license \
        -xplatform linux-arm-none-gnueabi-g++ \
        -prefix /home/zengjf/zengjfos/Qt5.8/QtLibOut \
        -nomake examples \
        -no-opengl \
        -no-iconv \
        -silent \
        -qpa linuxfb \
        -no-gtk \
        -qt-libjpeg \
        -qt-libpng \
        -tslib \
        -I/home/zengjf/zengjfos/Qt5.8/tslib-1.4/_install/include \
        -L/home/zengjf/zengjfos/Qt5.8/tslib-1.4/_install/lib

五、lib使用环境变量：
    1. 拷贝前面编译的lib库到ARM文件系统中；
    2. 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=1

        export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/lib:/usr/lib:$TSLIBDIR/lib:$QTDIR/lib
        export PATH=$PATH:/usr/bin:$TSLIBDIR/bin:/usr/sbin:/bin
