I'm creating a text-based RPG, but I have been recieving this error:

	int GetAge();
};


void PLAYER::SetAge(int newage)
{
	age = newage;
}

int PLAYER::GetAge()
{
	return age;
}
//PlayerHouse.cpp
#include "Library.h"

PLAYER player;

void PlayerHouse_Bedroom_WakeUp()
{
}

Any ideas?
Kind Regards,

Here's a few question you need to answer:
1) What IDE are you using?
2) What type of library are you trying to link?

If you're using Visual C++ Express 2010, and you're trying to link a static library, you can follow my instructions in a previous thread^[1].

Thanks for the fast answer.
I'm using Visual C++ Express 2010, the headers are already inside the solution and the project.
Kind Regards,

You have function definitions inside a header file, but not in the class itsself, specifically SetAge and GetAge. Either move them into the class, or put them in a cpp file.

Thanks to everyone.
