make
安装Python(由于此版本默认有Python2.7和Python3.2故可省去）
第一步：下载Qt4源代码
第二步：下载SIP( SIP is a tool forautomatically generating Python bindings for C andC++ libraries)
第三步：下载PyQt
第四步：配置SIP:
解压sip-XXXXX.tar.gz压缩包,进入sip-XXXXX目录
运行
python configure.py
注意：If you have multiple versions of Python installed then make sure
you use theinterpreter for which you wish SIP to generate bindings for.
也就是说我采用Python3.x进行开发，那么使用的命令是：python3 configure.py
shell下的结果是：
lieo@ubuntu:~/download/sip-4.14.2$ python3 configure.py
This is SIP 4.14.2 for Python 3.2.3 on linux2.
The SIP code generator will be installed in /usr/bin.
The sip module will be installed in /usr/lib/python3/dist-packages.
The sip.h header file will be installed in /usr/include/python3.2mu.
The default directory to install .sip files in is /usr/share/sip.
make
注意： 这步可能会报找不到Python.h文件的错误（没报错跳到make install)
这是因为缺失头文件和静态库包，
假如使用python2.7运行
sudo apt-get install python-dev
假如使用python3运行
sudo apt-get install python3-dev
make install
第五步：编译安装Qt4
Ubuntu默认没有编译环境，运行以下命令安装编译环境
sudo apt-get install build-essential
#进入qt源码目录运行
./configure
结果：Qt will be installed into /usr/local/Trolltech/Qt-4.8.4
make
make install
1.如果在./configure阶段，出现了以下错误
Basic XLib functionality test failed!
You might need to modify the include and library search paths by editing
QMAKE_INCDIR_X11 and QMAKE_LIBDIR_X11
那是因为没装有libxtst-dev，使用命令apt-get install libxtst-dev安装
2.如果在make阶段，出现一下错误
/usr/bin/ld: cannot find -lXrender
make[1]: *** [../../../../lib/libQtWebKit.so.4.7.3] 错误 1
make: *** [sub-webkit-make_default-ordered] 错误 2
那是因为没有装libxrender-dev
3.在qt create中，尝试编译测试，如果找不到qmake，则在工具－选项－QT4中手动设置qmake的位置。qmake的位置默认在/usr/local/Trolltech/Qt-4.8.4/bin/qmake。
当这几个步骤全部完成后，把“PATH=/usr/local/Trolltech/Qt-4.8.4/bin:$PATH
export PATH”加到.profile中，Qt就安装成功了。
或者 在.bashrc文件（如果你的shell是bash、ksh、zsh或者sh）中，添加下面这些行：
QTDIR=/usr/local/Trolltech/Qt-4.8.4
PATH=$QTDIR/bin:$PATH
LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH
第六步：安装PyQt
#进入PyQt源码目录运行以下命令安装PyQt
#前提是Qt4和SIP以正确安装
python configure.py
make
make install
至此配置完成
嵌入式Linux的ftp最常用来完成开发板和开发环境Linux系统之间的的文件传输功能，避免了频繁的U盘拷贝的过程。
根据安装手册安装就行啊
看看wo的网名？
