fedora9 中qt-xll ernel/qt_x11.h:65:22: error: X11/Xlib.h: No such file or directory 问题解决
安装 libX11-dev libXext-dev libXtst-dev
（在网上有的说用sudo等指令的，其实那个不适合fedora,在fedora下用yum install)
yum install libX11-dev
显示没有找到相应的package
而且输入yum install llibXext-dev也不行
输入yum install libXtst-dev也不行
三个库文件都是显示有问题。
自己想一想，可能不同的linux发行版，所对应的库文件名字不同吧。
好吧，索性全部安装上。
yum install libX*
安好了在./configura
错误依旧，难道是网上说错了，还是我压根没安装上，先从自己找原因
yum 命令更新文件，更新包全部都在，/var/cache/yum/fedora/packages
找到这里果然发现很多的rpm包

从里面找果然找到了libX11-devel-1.1.4-1.fc9.i386.rpm libXext-devel-1.0.4-1.fc9.i386.rpm
看来他还真没有安装上，好吧自己手动安装。
rpm -ivh libX11-devel-1.1.4-1.fc9.i386.rpm
这时候显示 需要libxau-devel
于是
yum install libXau-devel
接着执行
rpm -ivh libXext-devel-1.0.4-1.fc9.i386.rpm
最后，./configura果然，错误解决了。
最后我们来总结一下，要解决这个问题只需要几个库就可以了呢，
实际上只要两个：
yum install libXau-devel
执行完上面这条语句后，我在执行
yum install ibX11-devel
打印信息显示，该package已经安装
最后在安装
libXext-devel就可以了
