class'boost :: shared_ptr <T>'需要具有類'boost :: signals :: connection'的客戶端使用的dll接口

Question

編譯代碼時出現以下錯誤。作爲

boost::signal<void (long long int)> totalTimeChanged; 
boost::signal<void (unsigned int)> curTimeChanged; 

連接作爲

GStreamer::totalTimeChanged.connect(boost::bind(&MainWindow\ 
      ::total_time_changed, &player, _1)); 

編譯成功，但我怎麼擺脫這些編譯器警告的做

c:\boost_1_48_0\boost\signals\connection.hpp(118) : warning C4251: 'boost::signals::connection::con' : class 'boost 
::shared_ptr<T>' needs to have dll-interface to be used by clients of class 'boost::signals::connection' 

代碼的信號定義？

您可能需要閱讀How can I use Standard Library (STL) classes in my dll interface or ABI?所提到的 'UnknownRoad' 張貼在http://www.unknownroad.com/rtfm/VisualStudio/warningC4251.html
