undefined reference to `WinMain#16'
(7 answers)
Closed 8 years ago.
I have a really simple shell of of a program. The editor i use is Scite and my compiler is MingW.
The answer to this is that I'm missing a main but i do have a main().
Main.cpp
#include <iostream>
#include "Money.h"
using namespace std;
int main()
{
}
Money.cpp
#include "Money.h"
#include <iostream>
using namespace std;
Money::Money()
{
cout << "test"
}
Money.h
#ifndef MONEY_H
#define MONEY_H
class Money
{
public:
Money();
private:
};
#endif //MONEY_H
Everytime I try to compile Money.cpp it gives me the error
libmingw32.a(main.o):(.text.startup+0xa7): undefined reference to `WinMain#16'
And I'm not sure what's wrong with the program. All the files are in the same directory. I'm fairly new to programming in C++ so if you can give me a very basic answer or fix it be greatly appreciated.

WinMain is the entry point of Windows "Win32" programs.
You are probably using Visual Studio wizard to create your C++ project, but you chose a Windows C++ application. Such an application is expected to have WinMain() as an entry point (the #16 part is name mangling decorations, according to Visual C++ compiler rules), but you haven't provided that in your code.
If you want to build a C++ console-mode application (with the classical standard main() entry point), you may want to choose the Win32 Console Application option when creating a new project with Visual Studio.
E.g. this is a screenshot from Visual Studio 2010:
