QT4.5.3在海思3520A上移植步骤-修订版
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。

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!\n");
  else
  printf("It is Big_endian!\n");
  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
