C++/程序compile不了

[qq_36483087]

#include <iostream>
// this is elevator.h
using namespace std;



class Elevator{
	
public:

	Elevator( );
	void openDoors( );
	void closeDoors( );
	void letOffPassengers( int amount );
	void acceptPassengers( int amount );
	void requestFloor( int floor );
	/*bool isOnFloor( int floor );
	int getFloor( );
	int getPassengers( );*/

private:
	int my_Floor;
	int my_NumberOfPassengers;
	bool my_DoorsOpen;

};

// this is in elevator.cpp

#include <iostream>
#include <math.h> 
#include "Elevator.h"






Elevator::Elevator(){
		using namespace std;
		
		cout<<"Elevator on floor 1 with 0 passengers"<<endl;

}

void Elevator::openDoors(){
	using namespace std;
	
	cout<<"Elevator Door's Open"<<endl;
	
}

void Elevator::acceptPassengers( int pp  ){
		
	using namespace std;
	my_NumberOfPassengers = pp+my_NumberOfPassengers;
	cout<<"Elevator"<<" has " << my_NumberOfPassengers<<" passengers"<<endl;
	
}

void Elevator::requestFloor(int floor){
	using namespace std;
	my_Floor = floor;
	
	cout<<"Passengers want floor "<<my_Floor<<endl;
	
}

 void Elevator::letOffPassengers(int pp){
	using namespace std;
	
	my_NumberOfPassengers -= pp; 
	cout<<"Elevator"<<" has " << my_NumberOfPassengers<<" passengers"<<endl;
	
}

void Elevator::closeDoors(){
	using namespace std;
	
	cout<<"Elevator Door's close"<<endl;
	
}


/*int main(){
	
	Elevator e;
	
	return 0;
}*/

我在cmd 里面 compile elevator.cpp，
结果是 undefined reference to "WinMain@16'
collect2.exe : error : ld returned 1 exit status.


求助。

新建的是win32 application还是win32 console application？

[ooolinux]

应该控制台应用。字数。。

[yshuise]

新建项目不是更好？

[paschen]

项目属性——链接器——系统——子系统，改成：控制台 (/SUBSYSTEM:CONSOLE)

undefined reference to 'WinMain@16' 意思为提示找不到 WinMain 函数，有几种可能：
1.int main() 写成了 int mian() ，即找不到函数，或者没写主函数。
2.有可能是找不到一个参数字节总数为16个的XXX函数。
