BuildDll.h:
//防止重复链接
#ifndef BUILDDLL_H_
#define BUILDDLL_H_
//若有该宏,则为输出,否则为输入
#ifdef BUILDDLL_BUILD_EXPORTS
# define BUILDDLL_EXPORTS __declspec(dllexport)
#else
# define BUILDDLL_EXPORTS __declspec(dllimport)
#endif
BUILDDLL_EXPORTS int a;
BUILDDLL_EXPORTS void MyFunc();
#endif
注意,应在Properties->C/C++->Preprocessor->Preprocessor Definitions中添加BUILDDLL_BUILD_EXPORTS定义
有关输出路径请自行设置。
BuildDll.cpp:
#include "BuildDll.h"
BUILDDLL_EXPORTS void MyFunc()
{
a=1;
}
