php用宝塔安装fileinfo无法成功的解决方法

在使用宝塔安装PHP的fileinfo扩展是，发现一直安装不上，排除了内存大小问题，看了下错误日志，发现

Configuring for:

make: *** No targets specified and no makefile found.  Stop.

网上google了下，是缺少GCC配置，解决方案：

centos：

yum install gcc

debian&ubuntu：

 apt-get install gcc

还有一总错误日志是，configure: error: C preprocessor “/lib/cpp” fails sanity check

也google了下，是因为缺少必要的C++库，需要安装 gcc-c++

yum reinstall glibc-headers gcc-c++ -y
