c + +編譯問題

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

我想在我的編譯器Ubuntu的編譯和我收到此錯誤c + +編譯問題

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

請問是什麼-mt，我嘗試谷歌，但找不到任何信息。

如果我嘗試省略-mt參數我得到這個錯誤

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

出於好奇，如果你不知道'-mt'是什麼，你爲什麼使用它？ – juanchopanza 2013-05-03 07:55:19

這裏有兩個獨立的問題。要使事情正常工作，請刪除-mt並修復編譯錯誤。 – Arun 2013-05-03 07:56:38

兩個std::memset和std::strerror在<cstring>頭聲明，你需要#include那一個。

而GCC沒有-mt選項。
