在添加如下代码保证debug版本的arx文件也是使用MFC的release库
// 'DEBUG workaround' below prevents the MFC or ATL #include-s
// from pulling in "afx.h" that would force the debug CRT through
// #pragma-s.
#if defined(_DEBUG) && !defined(_FULLDEBUG_)
#define _DEBUG_WAS_DEFINED
#undef _DEBUG
#pragma message (" Compiling MFC header files in release mode.")
#endif #include MFC相关头文件 #ifdef _DEBUG_WAS_DEFINED
#define _DEBUG
#undef _DEBUG_WAS_DEFINED
#endif
