PHP的安裝雖然有時候很簡單，可是如果應用一多，我們安裝起來就很頭痛了！出錯最多的就是安裝PHP擴展的時候了。其實不管是你是Apache類的應用還是Nginx類的，PHP的安裝都不是很簡單，雖然網上有很多configure參數，但是那不一定是適合你的，因爲很多都直接關係着你的系統版本和內核。因此要自己親自不斷的調試，才能完全安裝成功。
本文總結了一些常見的configure錯誤信息和解決這些錯誤的經驗。
1、configure: error: No curses/termcap library found
網上有的說法是：–with-named-curses-libs=/usr/lib/libncursesw.so.5

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