dll调用

1.将.h .lib .dll 的第三方文件复制到项目文件夹下

 2.将.dll复制到输出目录exe目录下

3.在项目属性里添加lib文件路径 

 4.调用

#include"dll5/hello.h"
#include <iostream>

#pragma comment(lib,"QtWidgetsApplication2.lib")
using namespace std;
int main(int argc, char* argv[])
{
    Face2* Fa = Face2::CreateFace2();
    Fa->main2(argc, argv);
    Fa->main2(argc, argv);
    Fa->Init2();
    cout << Fa->InitAdd2(5, 6) << endl;
    return 0;
}

cpp文件中

#include"dll5/hello.h"
#include <iostream>

#pragma comment(lib,"QtWidgetsApplication2.lib")
using namespace std;
int main(int argc, char* argv[])
{
	Face2* Fa = Face2::CreateFace2();
	Fa->main2(argc, argv);
	Fa->main2(argc, argv);
	Fa->Init2();
	cout << Fa->InitAdd2(5, 6) << endl;
	return 0;
}
