一个 C 的 . LIB 文件 在 c++ 中调用的问题
用c 写了这么个.LIB
#include "stdlib.h "
#include "stdio.h "
#ifdef __cplusplus
extern "C " {
#endif
typedefstruct _LogFile{
FILE* pFile;
}LOGFILE,*LPLOGFILE;
#ifndef WINAPI
#define WINAPI __stdcall
#endif
int WINAPI InitLog(const char* pszStr);
int WINAPI UnInitLog();
#ifdef __cplusplus
}
#endif
我在 vc 用 控制台 来连接 就没有问题 ， 在其他 如 dll, windows application 下 就有问题 了
estdll1.cpp

[解决办法]
调整工程选项来解决。
[解决办法]
修改 C/C++ Code generation.run－time library
[解决办法]
Try to set 'Using MFC Share DLL ' in project settings of the windows application. If not successful, try to remove 'LIBCMTD.lib ' from link option of the windows application.

This error usually results from including a source code file multiple times. If you recognize any of the names in the message then it probably results from multiple inclusion of one of your own header files. Check to be sure that you 've used #ifndef/#define/#endif properly your header files. If you don 't recognize the name then it 's probably multiple inclusion of a system file (e.g., afxwin.h). Make sure that you haven 't explicitly included something in main.cpp that is already included in one of your own header files. Also check that you haven 't ＃i ncluded a .cpp file where you should have ＃i ncluded a .h file.
