c + +编译问题

[email protected]:~/Data$ g++ UDPEchoServer.cpp PracticalSocket.cpp -o udpskserv -lsocket -lnsl -mt

我想在我的编译器Ubuntu的编译和我收到此错误c + +编译问题

cc1plus: error: unrecognized command line option ‘-mt’

请问是什么-mt，我尝试谷歌，但找不到任何信息。

如果我尝试省略-mt参数我得到这个错误

PracticalSocket.cpp: In constructor ‘SocketException::SocketException(const string&, bool)’: 
PracticalSocket.cpp:33:38: error: ‘strerror’ was not declared in this scope 
PracticalSocket.cpp: In function ‘void fillAddr(const string&, short unsigned int, sockaddr_in&)’:

您是否在PracticalSocket.cpp中包含''或''？ – 2013-05-03 07:54:58

出于好奇，如果你不知道'-mt'是什么，你为什么使用它？ – juanchopanza 2013-05-03 07:55:19

这里有两个独立的问题。要使事情正常工作，请删除-mt并修复编译错误。 – Arun 2013-05-03 07:56:38

两个std::memset和std::strerror在<cstring>头声明，你需要#include那一个。

而GCC没有-mt选项。
