BOOST multiple definition of `boost::system::throws
QT在添加#include"mongo/client/dbclient.h" 之前构建是通过的,添加之后报multiple definition of `boost::system::throws,之前报boost::system::generic_category()后来在error_code.hpp中添加了一句#define BOOST_ERROR_CODE_HEADER_ONLY后来不报了,现在添加#include"mongo/client/dbclient.h"后报错重复定义boost::system::throws,请问这是怎么回事
