2440+2.6.33 QT-4.5.3移植（十）

分类：

2011-04-23 18:35:14

原文地址：2440+2.6.33 QT-4.5.3移植（十） 作者：yuweixian4230

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  
  1. 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
  2. ywx@yuweixian:~/yu/qt/hello_cn$ ls
  3. hello_cn.cpp hello_cn.h main.cpp
  4. 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
  1. ywx@yuweixian:/usr/local/Trolltech/QtEmbedded-4.5.3-arm$ ls
  2. bin examples lib plugins setenv.sh
  3. demos include mkspecs qtc-debugging-helper
  4. 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
  1. ywx@yuweixian:~/yu/qt/hello_cn$ arm-linux-readelf -d hello_cn

  3. Dynamic section at offset 0x2b0c contains 34 entries:
  4.   Tag Type Name/Value
  5.  0x00000001 (NEEDED) Shared library: [libQtGui.so.4]
  6.  0x00000001 (NEEDED) Shared library: [libQtNetwork.so.4]
  7.  0x00000001 (NEEDED) Shared library: [libQtCore.so.4]   ###这三个是 qt库，
  8.  0x00000001 (NEEDED) Shared library: [librt.so.1]       ### 下面的都是 busybox 中生成库
  9.  0x00000001 (NEEDED) Shared library: [libdl.so.2]
  10.  0x00000001 (NEEDED) Shared library: [libpthread.so.0]
  11.  0x00000001 (NEEDED) Shared library: [libstdc++.so.6]
  12.  0x00000001 (NEEDED) Shared library: [libm.so.6]
  13.  0x00000001 (NEEDED) Shared library: [libgcc_s.so.1]
  14.  0x00000001 (NEEDED) Shared library: [libc.so.6]
  15.  0x0000000f (RPATH) Library rpath: [/usr/local/Trolltech/QtEmbedded-4.5.0-arm/lib]
  16.  0x0000000c (INIT) 0x9d50
  17.  0x0000000d (FINI) 0xa80c
  18.  0x00000019 (INIT_ARRAY) 0x12b00
  19.  0x0000001b (INIT_ARRAYSZ) 4 (bytes)
  20.  0x0000001a (FINI_ARRAY) 0x12b04
  21.  0x0000001c (FINI_ARRAYSZ) 4 (bytes)
  22.  0x00000004 (HASH) 0x8168
  23.  0x00000005 (STRTAB) 0x8c50
  24.  0x00000006 (SYMTAB) 0x85f0
  25.  0x0000000a (STRSZ) 3315 (bytes)
  26.  0x0000000b (SYMENT) 16 (bytes)
  27.  0x00000015 (DEBUG) 0x0
  28.  0x00000003 (PLTGOT) 0x12c44
  29.  0x00000002 (PLTRELSZ) 672 (bytes)
  30.  0x00000014 (PLTREL) REL
  31.  0x00000017 (JMPREL) 0x9ab0
  32.  0x00000011 (REL) 0x9a80
  33.  0x00000012 (RELSZ) 48 (bytes)
  34.  0x00000013 (RELENT) 8 (bytes)
  35.  0x6ffffffe (VERNEED) 0x9a10
  36.  0x6fffffff (VERNEEDNUM) 3
  37.  0x6ffffff0 (VERSYM) 0x9944
  38.  0x00000000 (NULL) 0x0
  39. 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
  1. fonts libQtGui.so libQtNetwork.so.4
  2. libQtCore.so libQtGui.so.4 libQtNetwork.so.4.5
  3. libQtCore.so.4 libQtGui.so.4.5 libQtNetwork.so.4.5.3
  4. libQtCore.so.4.5 libQtGui.so.4.5.3
  5. 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/
  1. ywx@yuweixian:/usr/local/Trolltech/QtEmbedded-4.5.3-arm/plugins$ ls
  2. accessible iconengines imageformats sqldrivers
  3. 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
  1. # Ash profile
  2. # vim: syntax=sh

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

  7. ###################################### qt 添加开始
  8. export set HOME=/root
  9. export set QTDIR=/opt/qt-4.5
  10. export set QPEDIR=/opt/qt-4.5
  11. export set QWS_DISPLAY="LinuxFB:/dev/fb0"

  25. PS1='[\u@\h \W]# '
  26. PATH=$PATH

  28. HOSTNAME=`/bin/hostname`

  30. export USER LOGNAME PS1 PATH

7.在/bin/建立 qt4 执行文件
  1. #!/bin/sh

  3. echo Start qt-4.5 > /dev/ywx_serial0

  5. export set HOME=/root
  6. export set QTDIR=/opt/qt-4.5

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

8.加入自动启动项  gedit /etc/init.d/rcS
  1. ifconfig lo 127.0.0.1
  2. net_set&

  4. qt4 &   加入 qt4 自动启动

  6. /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
