2440+2.6.33 QT-4.5.3移植（十）

参考资料：天嵌科技出品--Qt程序开发完全手册之24小时超级版本_V2.2_20100606.pdf
           qt-4.5 移植篇章

说明：移植qt4.5时，使用的环境配置
      开发板：TQ2440 256MB nandflash 64MB sdram  东华3.5寸屏
      uboot：TQ_W35 东华2009 年的uboot
      内核：2440+2.6.33 UDA声卡移植（九） 移植后，继续的内核
      文件系统：使用自己保存的 root-2.6.33-final.tar.bz2 
最原始的文件系统镜像root-2.6.33-final.bin 9.4MB

1.QT4.5的环境建立


   3.这里简单介绍建立好  qt 开发环境后使用的方法：
比如说编译tq提供的 hello_cn 这个应用程序 ，这里加上 三个源码附件hello_cn.rar hello_cn.rar  

我删除了tq提供的/hello_cn/目录下其他的文件，只留下了下面三个文件
ywx@yuweixian:~/yu/qt/hello_cn$ ls
hello_cn.cpp  hello_cn.h  main.cpp
ywx@yuweixian:~/yu/qt/hello_cn$

将 qmake 文件指向 arm 架构
ywx@yuweixian:~/yu/qt/hello_cn$ source /usr/local/Trolltech/QtEmbedded-4.5.3-arm/setenv.sh
ywx@yuweixian:~/yu/qt/hello_cn$

编译 源文件
ywx@yuweixian:~/yu/qt/hello_cn$ qmake -project   编译生成 工程文件
ywx@yuweixian:~/yu/qt/hello_cn$ qmake            编译生成 Makefile
ywx@yuweixian:~/yu/qt/hello_cn$ make             编译文件 Makefile

参看生成文件，其中hello_cn 就是我们需要的 二进制应用程序文件

ywx@yuweixian:~/yu/qt/hello_cn$ ls
hello_cn      hello_cn.h  hello_cn.pro  main.o    moc_hello_cn.cpp
hello_cn.cpp  hello_cn.o  main.cpp      Makefile  moc_hello_cn.o
ywx@yuweixian:~/yu/qt/hello_cn$

当让，我们也可以使用 qt creator  实现上面一样的功能，具体参考 qt-4.5 篇章中的qt creator 使用部分

2.qt4.5 文件系统的制作
 
   1.在文件系统 opt/新建目录 qt-4.5 目录
   2.复制 4.5.3-arm/lib 目录到 文件系统  qt-4.5/下，删除掉出“fonts”和*.so* 文件外其他的文件

ywx@yuweixian:/usr/local/Trolltech/QtEmbedded-4.5.3-arm$ ls
bin    examples  lib      plugins               setenv.sh
demos  include   mkspecs  qtc-debugging-helper
ywx@yuweixian:/usr/local/Trolltech/QtEmbedded-4.5.3-arm$

  3.在这里我只移植了hello_cn 这个应用程序，所以在第 2 步骤中，我还删除了其他.so 文件。
     3.1 使用 arm-linux-readelf -d hello_cn 查看动态链接库
         所以我只复制了 下面三个 qt 库

ywx@yuweixian:~/yu/qt/hello_cn$ arm-linux-readelf -d hello_cn

Dynamic section at offset 0x2b0c contains 34 entries:
  Tag        Type                         Name/Value

 0x00000001 (NEEDED)                     Shared library: [libQtCore.so.4]   ###这三个是 qt库，
 0x00000001 (NEEDED)                     Shared library: [librt.so.1]       ### 下面的都是 busybox 中生成库

ywx@yuweixian:~/yu/qt/hello_cn$

   
     3.2 复制上面提到的 qt 动态链接库  到文件系统 qt-4.5/lib/下

fonts               libQtGui.so        libQtNetwork.so.4
libQtCore.so        libQtGui.so.4      libQtNetwork.so.4.5
libQtCore.so.4      libQtGui.so.4.5    libQtNetwork.so.4.5.3
libQtCore.so.4.5    libQtGui.so.4.5.3
libQtCore.so.4.5.3  libQtNetwork.so

4.复制 -arm/plugins/imageformates 文件到 文件系统/opt/qt-4.5/plugins/

ywx@yuweixian:/usr/local/Trolltech/QtEmbedded-4.5.3-arm/plugins$ ls
accessible  iconengines  imageformats  sqldrivers
ywx@yuweixian:/usr/local/Trolltech/QtEmbedded-4.5.3-arm/plugins$

5.建立 opt/qt-4.5/bin 目录
  在bin 目录中加入我们上面制作的二进制应用程序 hell0_cn

6.修改文件系统的/etc/profiel 文件， 为了单独运行QT程序

# Ash profile
# vim: syntax=sh

# No core files by default
#ulimit -S -c 0 > /dev/null 2>&1

###################################### qt 添加开始
export set HOME=/root
export set QTDIR=/opt/qt-4.5
export set QPEDIR=/opt/qt-4.5
export set QWS_DISPLAY="LinuxFB:/dev/fb0"
export set QWS_DISPLAY="LinuxFB:mmWidth130:mmHeight100:0"   注意这里没有空格 哟
export set QWS_KEYBOARD="TTY:/dev/tty1"

export set QT_PLUGIN_PATH=$QTDIR/plugins/
export set QT_QWS_FONTDIR=$QTDIR/lib/fonts
export set PATH=$QPEDIR/bin:$PATH
export set LD_LIBRARY_PATH=$QTDIR/lib:$QPEDIR/plugins/imageformats:$LD_LIBRARY_PATH

####################################### qt 添加结束


USER="`id -un`"
LOGNAME=$USER
PS1='[\u@\h \W]# '
PATH=$PATH

HOSTNAME=`/bin/hostname`

export USER LOGNAME PS1 PATH

7.在/bin/建立 qt4 执行文件

#!/bin/sh

echo Start qt-4.5 > /dev/ywx_serial0

export set HOME=/root
export set QTDIR=/opt/qt-4.5
export set QPEDIR=/opt/qt-4.5
export set QWS_DISPLAY="LinuxFB:/dev/fb0"
export set QWS_DISPLAY="LinuxFB:mmWidth130:mmHeight100:0"
export set QWS_KEYBOARD="TTY:/dev/tty1"

export set QT_PLUGIN_PATH=$QTDIR/plugins/
export set QT_QWS_FONTDIR=$QTDIR/lib/fonts
export set PATH=$QPEDIR/bin:$PATH
export set LD_LIBRARY_PATH=$QTDIR/lib:$QPEDIR/plugins/imageformats:$LD_LIBRARY_PATH

$QPEDIR/bin/hello_cn -qws 1>/dev/null 2>/dev/null

8.加入自动启动项  gedit /etc/init.d/rcS

ifconfig lo 127.0.0.1
net_set&

qt4 &   加入 qt4 自动启动

/bin/hostname -F /etc/sysconfig/HOSTNAME

9.好了，这样就可以了

  mkyaffs2image root-2.6.33-final root-2.6.33-fianl.bin
  .bin 文件有 30 MB
注意：生成的bin 文件太大，会出错 ，下都下不进开发板，自己遇到了这个问题


10.启动，详细信息
