　　PHP的安装虽然有时候很简单，可是如果应用一多，我们安装起来就很头痛了！出错最多的就是安装PHP扩展的时候了。其实不管是你是Apache类的应用还是Nginx类的，PHP的安装都不是很简单，虽然网上有很多configure参数，但是那不一定是适合你的，因为很多都直接关系着你的系统版本和内核。因此要自己亲自不断的调试，才能完全安装成功。
　　本文总结了一些常见的configure错误信息和解决这些错误的经验。
　　1、configure: error: No curses/termcap library found
　　网上有的说法是：–with-named-curses-libs=/usr/lib/libncursesw.so.5

　　centos: yum -y install ncurses-devel
　　debian: apt-get install libncurses5-dev
