c++11使用

在gcc中加入-std=c++11.
编译错误1
 error: ‘shared_ptr’ is not a member of ‘std’
  std::shared_ptr<net_que_handle> q_handle = make_shared<net_que_handle>();
  解决：gcc中加入-std=c++11，如cc -g -std=c++11 -o xxx
编译错误2
 unable to find string literal operator ‘operator"" __FILE__’
 #define PROXY_LOG(format,...) printf("FILE:"__FILE__",line:%05d:"format"/n",__LINE__,##__VA_ARGS__)
 错误解决：c++11要求字符串和变量拼接的时候要加空格，改为
 #define PROXY_LOG(format,...) printf("FILE:" __FILE__ ",line:%05d:" format "/n",__LINE__,##__VA_ARGS__)即可
