问题主要有2点：
1.error LNK2038: 检测到“RuntimeLibrary”的不匹配项: 值“MD_DynamicRelease”不匹配值“MT_StaticRelease”(BACKUPDLG.obj 中)
  log4cplusS.lib 重新release一次，MD->MT
2.log4cplusSD.lib(patternlayout.obj) : error LNK2038: 检测到“_ITERATOR_DEBUG_LEVEL”的不匹配项: 值“2”不匹配值“0”(BACKUPDLG.obj 中)
 去掉了ifndef 宏定义，值保留
#pragma comment(lib,"E:/library/log4cplus/msvc8/binRelease/log4cplusS.lib") 


#ifndef _DEBUG 
#pragma comment(lib,"E:/library/log4cplus/msvc8/binDebug/log4cplusSD.lib") 
#else 
#pragma comment(lib,"E:/library/log4cplus/msvc8/binRelease/log4cplusS.lib") 
#endif
