Undefined references using files

Question

I have multiple files with a main driver below calling functions in a header file then going to a .cpp file. However I am getting an undefined reference on moneyCout() and choice(number) shown here:

#include <iostream>
#include<stdlib.h>
#include<fstream>
#include "Menu.h"
#include "Gates.h"
#include "Money.h"
#include "Lot.h"

using namespace std;

void moneyCount();

int main()
{

    std::ifstream infile;
    infile.open("parking_account.txt");
    while(!infile.eof())
    {
        cin>>TotalBills>>ones>>fives>>tens>>twen>>quar;
    }
    infile.close();
    int number;
   cout<<"----------------------------------------------------\n\n"
    <<"------------------------------------------\n------------------------------------------------------\n"
    <<"                     Parking Machine Accounts\n"
    <<"-------------------------------------------------------------------\n------------------------------------------------------------\n"
    <<"Sr. No. : BILL NAME                  : BILL COUNT : COST(in $)\n"
    <<"------------------------------------------------------------------------\n";
    moneyCount();
    cout<<"Which Gate to enter?\n"
    <<"1  Gate A\n"
    <<"2  Gate B\n"
    <<"3  Gate C\n"
    <<"4  Report to file\n"
    <<"5  Exit\n"
    <<"Gate option(1-3):  ";
    cin>>number;
    choice(number);
}

The header file looks like

#ifndef MENU_H_INCLUDED
#define MENU_H_INCLUDED
#include "Money.h"
#include "Gates.h"
void choice(int choice);
void menu_2_A(int choice);
void menu_3(int choice);
void costMenu(int cost);


#endif // MENU_H_INCLUDED

the .cpp file for this header is

#include "Menu.h"
#include "Gates.h"
#include <stdlib.h>
#include <fstream>
#include <iostream>

lot.h

#ifndef LOT_H_INCLUDED
#define LOT_H_INCLUDED
#include "Gates.h"

int park_lot();
int park_lot_dist();


#endif // LOT_H_INCLUDED

once I resolve these errors the other errors should be similar to solve. thanks in advance.

From what I can see, in the main file, 4 header files were included, so there should be at least 4 matching cpp files. — Evan Carslake, Nov 29 '14 at 03:30

"Undefined reference" by the linker means that it cannot find the compiled code for those symbols. That generally means that they're not defined, or defined incorrectly. Let's dig in with your particular example.

For moneyCount, I don't see an actual definition, only a declaration. You have

void moneyCount();

That's good, but somewhere in one of your .cpp files, you need to provide a body for it. That is:

void moneyCount() {
  // your stuff here
}

For choice(number), you have defined a global function as:

void choice(int choice){
    // some stuff
}

but have declared it as an instance function

class menu{
public:
void choice(int choice);
// more stuff
}

For this, you should change your definition to be:

void menu::choice(int choice){
    // some stuff
}

if i dont use the class it shouldnt make that much of a difference right? – McGuckinator Nov 29 '14 at 03:50
Correct. Looks like you edited the source and now have the declaration for a global function. You should be good to go. – kenrose Nov 29 '14 at 04:06
still the same errors with the main driver – McGuckinator Nov 29 '14 at 04:08

First problem is:

You are getting an undefined reference error for the moneyCout() function because it doesn't exist as you didn't define the function.

Please learn how to define functions. std::ofstream ReadMe; should be defined in main( my preference ).

Please define moneycount function. Don't just initialize it!

Show us the gate functions in gate.cpp that might be the problem.

Remember to have the class and scope operator before each function in menu.cpp like this

void menu::choice(int) 
void menu::costMenu(int)

Last problem is, you actually have to create class object to refer to the functions in your class like this.

menu Menu;
Menu.choice(number);

Please correct all errors.

all the files are on except the .cpp for lot: the entire file is too long to put in. – McGuckinator Nov 29 '14 at 04:01
all I need is gate functions from gate.cpp – Nov 29 '14 at 04:04
thanks didn't see that – Nov 29 '14 at 04:11
use classes they are made to make functions and variables more easy to access c++ classes - http://www.tutorialspoint.com/cplusplus/cpp_classes_objects.htm – Nov 29 '14 at 04:13
And will get this program working? – McGuckinator Nov 29 '14 at 04:15
class make everything easier and much easier to access function. It will get this program working for sure IF you make the class/class functions correctly. – Nov 29 '14 at 04:17
