在我们源码编译安装PHP的时候，总会遇到各种各样的问题，每次编译的时候都会提示我们去安装其他
要依赖的包，笔者根据自己多次安装的经验以及网络上找到的不少资料，将出错提示与解决方法做了一
个小小的汇总。
首先，我们在编译的时候需要安装很多的包，而这些包不一定在我们本来的yum源中有，所以我们可以
先去安装一个yum的扩展源。
yum install -y release
yum install -y freetype-devel libevent libevent-devel libxml2 libxml2-devel ncurses ncurses-devel openssl openssl-devel libjpeg libjpeg-devel libpng libpng–devel zlib-devel bzip2 bzip2-devel libmcrypt libmcrypt-devel
然后我们再来看看可能会遇到的各种错误以及解决方法：
错误：configure: error: freetype-config not found.
解决：yum install freetype-devel
错误：configure: error: libevent >= 1.4.11 could not be found
解决：yum -y install libevent libevent-devel
错误：configure: error: Please reinstall the mysql distributio
解决：yum -y install mysql-devel
错误：make: *** [sapi/fpm/php-fpm] error 1
解决：用make ZEND_EXTRA_LIBS='-liconv'编译
