关于libjingle与mfc的问题

我已经顺利的编译了libjingle,并且生成了libjingle.lib.把它加入了项目的additional dependence里面,而且在项目的additional include directory里面加入了C:\Documents and Settings\Administrator\桌面\libjingle-0.4.0\libjingle-0.4.0这个目录.(MFC 应用程序项目) 在项目的stdafx.h中加入了 
#include "talk/base/win32.h" 
#include "talk/base/fileutils.h" 
#include "talk/base/pathutils.h" 
#include "talk/base/helpers.h" 
#include "talk/base/httpclient.h" 
#include "talk/base/logging.h" 
#include "talk/base/physicalsocketserver.h" 
#include "talk/base/ssladapter.h" 
#include "talk/xmpp/xmppclientsettings.h" 
#include "talk/p2p/client/httpportallocator.h" 
#include "talk/p2p/client/sessionmanagertask.h" 
#include "talk/session/fileshare/fileshare.h" 
我给程序的初始化函数里面就写了一个 
talk_base::InitializeSSL();  
却出现了很多连接错误,这是怎么回事啊 错误如下:
