基础知识（九）boost+vs2015安装配置

在调用boost头文件的时候采用：

<span style="font-size:18px;">#include "boost/program_options.hpp"#include "boost/filesystem.hpp"</span>

结果出现了连接错误：

于是添加了#define #undef语句：

<span style="font-size:18px;">#define BOOST_NO_CXX11_SCOPED_ENUMS#include "boost/program_options.hpp"#include <boost/filesystem.hpp>#undef BOOST_NO_CXX11_SCOPED_ENUMS</span>

结果就OK了。
