    2015年3月29日星期日, 16:59:03

     

    1.首先要保证已经安装了海思的交叉编译器;

    #arm-hi  + Tab key to show which toolchainhave been installed

    [root@roger]#arm-hi

    arm-hisiv100nptl-linux-addr2line  arm-hisiv100nptl-linux-gprof

    arm-hisiv100nptl-linux-ar         arm-hisiv100nptl-linux-ld

    arm-hisiv100nptl-linux-as         arm-hisiv100nptl-linux-nm

    arm-hisiv100nptl-linux-c++        arm-hisiv100nptl-linux-objcopy

    arm-hisiv100nptl-linux-c++filt    arm-hisiv100nptl-linux-objdump

    arm-hisiv100nptl-linux-cpp        arm-hisiv100nptl-linux-ranlib

    arm-hisiv100nptl-linux-g++        arm-hisiv100nptl-linux-readelf

    arm-hisiv100nptl-linux-gcc        arm-hisiv100nptl-linux-size

    arm-hisiv100nptl-linux-gcc-4.4.1  arm-hisiv100nptl-linux-strings

    arm-hisiv100nptl-linux-gccbug     arm-hisiv100nptl-linux-strip

    arm-hisiv100nptl-linux-gcov

     

     

    2.下载qt-embedded-linux-opensource-src-4.5.3;

    下载地址:

    2.1 官网地址:

    ftp://ftp.qt.nokia.com/qt/source/qt-embedded-linux-opensource-src-4.5.3.tar.gz

     

    2. 2百度网盘:http://pan.baidu.com/wap/shareview?&shareid=2505547396&uk=1627858430&dir=%2F%E9%9B%B6%E5%9F%BA%E7%A1%80%E5%AD%A6%E4%B9%A0%E5%B5%8C%E5%85%A5%E5%BC%8FLinux%E7%9A%84QT%E7%BC%96%E7%A8%8B%E5%BC%80%E5%8F%91%E8%BD%AF%E4%BB%B6&page=1&num=20&fsid=1830301785&third=0

     

     

     

    3.更改qt-embedded-linux-opensource-src-4.5.3/mkspecs/qws/linux-arm-g++/qmake.conf如下

     

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

    include(../../common/linux.conf)

    include(../../common/qws.conf)

    # modificationsto g++.conf

     

    #arm-hi  + Tab key to show which toolchainhave been installed

    CCHEAD?= arm-hisiv100nptl-linux-

     

    QMAKE_CC                = $(CCHEAD)gcc

    QMAKE_CXX               =$(CCHEAD)g++

    QMAKE_LINK              =$(CCHEAD)g++

    QMAKE_LINK_SHLIB        = $(CCHEAD)g++

     

    #modifications to linux.conf

    QMAKE_AR                = $(CCHEAD)ar cqs

    QMAKE_OBJCOPY           =$(CCHEAD)objcopy

    QMAKE_STRIP             = $(CCHEAD)strip

     

    load(qt_config)

     

     

    4.配置qt-embedded-linux-opensource-src-4.5.3

        cd   qt-embedded-linux-opensource-src-4.5.3

     

     

       ./configure -embedded arm

        -qt-libpng

        -qt-libjpeg

        -qt-libtiff

        -qt-libmng

        -qt-gif

        -qt-zlib

        -fast

        -no-webkit

        -nomake examples

        -nomake demos

        -static

        -little-endian

         --prefix=/usr/local/qt-4.5.3

     

        其中 --prefix是编译QT后要安装的路径,可以根据自己实际情况更改。

       

    5.编译QT库  --  此处较为耗时,大概30min

    gmake

     

     

    6. 安装QT库

       gmake install

      

      

    7.更改虚拟机的环境变量

    export QMAKESPEC=/usr/local/qt-4.5.3/mkspecs/qws/linux-arm-g++

    export  PATH="/usr/local/qt-4.5.3/bin":$PATH

     

    要根据实际情况更改上边的2个环境变量。/usr/local/qt-4.5.3是自定义的QT的安装路径

     

    8.检查QT环境变量是否设置成功。

      输入 which  qmake 后显示路径应该是QT安装目录里的qmake.

    [root@rogerqt-4.5.3]# which  qmake

    /usr/local/qt-4.5.3/bin/qmake

     

    9.qt 库安装完成。

     


     ==========================================================================

    安装过程中的相关出错信息:

    检索 Log信息 发现: 交叉编译工具链的名称写错了, 修正后即可;



    2、 

    The target system byte order could not be detected!
    Turn on verbose messaging (-v) to see the final report.
    You can use the -little-endian or -big-endian switch to
    ./configure to continue.

    根据提示信息 可知: 未指定 大小端 模式, 指定      -little-endian 即可;

    /*  测试 大小端 模式 Sample, 编译执行文件 到目标机运行即可 */
    #include "stdio.h"
    int main()
    {
      union w
     {
      int a;  //4 bytes
      char b; //1 byte
     } c;
      c.a=1;
      if (c.b==1)
      printf("It is Little_endian!
    ");
      else
      printf("It is Big_endian!
    ");
      return 1;
    }
    


    Step 4:

    # ./configure -embedded arm  -qt-libpng -qt-libjpeg -qt-libtiff -qt-libmng -qt-gif -qt-zlib  -fast -no-webkit -nomake examples -nomake demos-little-endian -static --prefix=/usr/local/qt-4.5.3
