Multiple Definition Error
I recently started teaching myself C++ from varrious tutorials and books, and once I felt I had a decent understanding of syntax, input, output and classes, I figured I'd try to write a basic text adventure console app.
The class definition seems to work fine, but I keep getting a "multiple definition" error on the testRoom instance I create, despite the fact that it's only created once.
At first I thought I might be calling the file twice (I'm keeping the list of rooms in a separate header file), but that is not the case. I've looked online and can't seem to figure out what is wrong with it...
source.cpp
Code:
/*
Name: Text Adventure
Copyright: None
Author: Timothy Sassone
Date: 14/02/09 22:42
Description: A basic text adventure engine, written to practice basic C++ skills.
*/
#include <iostream>
#include <vector> //I plan on using a vector to hold the rooms
#include <string>
#include "roomDef.cpp"
#include "roomListing.cpp"
int main()
{
bool quit = 0;
while(quit==0)
{
//Main loop
quit=1;
}
return 0;
}
roomDef.cpp
Code:
#ifndef ROOM_DEF //Prevents repeated class definition
#define ROOM_DEF
#include <iostream>
#include <string>
using namespace std;
class Room {
private:
string itsName;
string itsDesc;
public:
string getName() {
return itsName;
}
string getDesc() {
return itsDesc;
}
void setName(string newName) {
itsName=newName;
}
void setDesc(string newDesc) {
itsDesc=newDesc;
}
Room(string name, string desc) { //constructor
itsName=name;
itsDesc=desc;
}
~Room() {}; //Destructor
};
#endif
roomListing.cpp
Code:
#ifndef ROOM_LIST //Prevents repeat definitions.
#define ROOM_LIST
#include "roomDef.cpp" //So I have access to the Room class
Room testroom1("1", "2"); //Create two test rooms
Room testroom2("2", "3");
#endif
I'm compiling with Dev-C++, and the error it gives is:
multiple definition of `testroom1'
first is defined here
multiple definition of `testroom2'
first is defined here
ld returned 1 exit status
C:\Documents and Settings\Timothy Sassone\Text Adventure\Makefile.win [Build Error] ["Text] Error 1
Neither of the "first defined here" errors is giving me a line or even file name. Any idea why it is giving me this error?
Thank you for your time,
Timothy
