具体的安装办法：
1、去这里下载Qt 4.4.0 for X11 OpenSource版。
2、下载过来的是 qt-x11-opensource-src-4.4.0.tar.gz 文件，我们用tar命令解压一下。
tar zxvf qt-x11-opensource-src-4.4.0.tar.gz
3、把这个目录移到/usr/local目录下，或者不移，放在/home目录也无所谓，下面的安装过程是把这个目录移到/usr/local目录下，改名为qt，如果您没有移动，在设置的时候注意目录。
4、修改（可以使用vi编辑器或者gedit）自己目录下的.bash_profile 或者 .profile或者是/etc/profile这个文件，加入下面的代码：
QTDIR=/usr/local/qt
PATH=$QTDIR/bin:$PATH
MANPATH=$QTDIR/man:$MANPATH
LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH
export QTDIR PATH MANPATH LD_LIBRARY_PATH
5、注销一下用户或者 source .bash_profile 一下，使配置文件生效。
6、进入QT的目录，开始编译
./configure
输入yes同意GPL/QPL协议。在网络上还看到这个命令 ./configure -thread，为了支持多线程，大家还是敲一下这些命令好了。（不知道./configure -thread 和 ./configure 命令有没有重复）
7、开始make 这步要一两个小时
make
8、开始install（网上的一些手册没有这步，会出现 error while loading shared libraries: libQTDesignerComponents.so4 错误，我make install一下之后，就OK了。）这步也要挺久的，大概几十分钟吧。
make install
9、进入QT的目录，进入bin目录，然后运行 ./designer，大家可以看到图形界面了吧。
