运行主机：ubuntu 32位 11.04
QT版本：2.2.0
开发板：TQ2440
源码安装路径（修改相关脚本x86-qtopia-2.2.0_build等，摈弃了解压缩后的文件都放在/opt/EmbedSky/Qte的问题）：/opt/newSSD/tq2440/source/Qte
GCC版本:3.4.4
说明：鉴于网上的讨论-------------------ubuntu11.04自带的gcc4.5.2编译Qt2.2.0会出现很多问题，所以把GCC的版本降低，出现的错误大大减少。参考文献：http://jinsuo2007.blog.163.com/blog/static/1922799520104137259556/
1. 安装GCC（包含G++）3.4.4
安装方法参考《ubuntu10.4系统下GCC降级安装》
下载地址http://mirror.bjtu.edu.cn/gnu/gcc/gcc-3.4.4/
先解压
$ ./configure --prefix=/opt/newSSD/tq2440/compile/gcc-3.4.4/ --mandir=/opt/newSSD/tq2440/compile/gcc-3.4.4/share/man --infodir=/opt/newSSD/tq2440/compile/gcc-3.4.4/share/info --enable-shared --enable-threads=posix --disable-checking --with-system-zlib --enable-__cxa_atexit --enable-languages=c,c++
$ make && make install
2. 编译错误
错误:asm/page.h:没有那个文件或目录 In file included from kernel/qgfx_qws.h:39,
解决办法：
http://tensing.blog.sohu.com/114887954.html
从linux2.6.25.8拷贝出linux-2.6.25.8/include/asm-x86/page.h放在/usr/include/asm目录下即可
3. 编译出现错误：
/usr/bin/ld: cannot find -luuid
/usr/bin/ld: cannot find -lqte

解决办法：
http://blog.csdn.net/r91987/article/details/6849730
$apt-get install libv4l-dev
$ vi x86-qtopia-2.2.0/qtopia/src/applications/camera/videocaptureview.cpp
#include <linux/videodev.h>
替换为
#include <libv4l1-videodev.h>

opt/EmbedSky/Qte/pro/build
mv: 无法获取"pro" 的文件状态(stat): 没有那个文件或目录
Build user program , please wait ...
./x86-qtopia-2.2.0_build: 第 45 行: cd: x86-qtopia-2.2.0/pro: 没有那个文件或目录
./x86-qtopia-2.2.0_build: 行 46: ./build: 没有那个文件或目录
解决办法：
发现原因是x86-qtopia-2.2.0_build脚本里的解压路径不对，改正即可。
------------------------------以下，Qt就可以运行了。
