Thread: undefined reference error when compiling

I am getting the above error on the lines marked here in the code. I have included my functions declarations as well. Can someon please tell what is wrong and what can I do to remedy it?

Code:

StackCities(StartCity, EndCity, DistanceMatrix,
                  PredecessorMatrix, st, Reverse);//<--------HERE

      // Display the route - Start city to End city
      //==========================================================
      DispRoute(Reverse, st);     // For testing

      // Display the Intervening cities and the distances between
      // them including the cumulative distances for the route
      //==========================================================
      DispItinerary(st, StartCity, EndCity, DistanceMatrix, Reverse);//<-----HERE

The function declarations:

Code:

void PrintPredChart(int cities, StringTable &st, TwoDIntArray &PredecessorArray);
void DispItinerary(StringTable &st, string StartCity,  string EndCity, TwoDIntArray &DistanceMatrix, Stack &Reverse);
void DispRoute(Stack &Reverse, StringTable &st);
void InitMatrices(TwoDIntArray &DistanceMatrix, TwoDIntArray &PredecessorMatrix, int cities);
void getMapData(ifstream &in, StringTable &st, char * buf, TwoDIntArray &DistanceMatrix, TwoDIntArray &PredecessorMatrix);
void FloydWarshall(TwoDIntArray &DistanceMatrix, TwoDIntArray &PredecessorMatrix, int cities);
void StackCities(string StartCity, string EndCity, TwoDIntArray &DistanceMatrix, TwoDIntArray &PredecessorMatrix, StringTable &st, Stack &Reverse);

just in case:

Code:

int menuChoice;
    string StartCity;
    string EndCity;
    string fileName;
    //ifstream in;

    cout<<"Welcome to J.A.C. P2 Assignment\n"
      "\n"
      "This program will find the shortest path\n"
      "from One city to all other cities if there\n"
      "is a connecting node, find the shortest path\n"
      "between two cities or find the shortest\n"
      "between three or more cities.\n"<<endl;

    cout<<"Please make a choice of what you would like to do:\n"<<endl;

    cout<<"  1------> Shortest Path between 2 cities.\n"
          "  2------> Shortest Path between 3 or more cities.\n"
          "  3------> Shortest Path from 1 city to all.\n"
          "  9------> Take your ball and go home!\n"<<endl;
    cout<<"Waiting on you: "; cin>>menuChoice;

    switch (menuChoice) {
        case 1:
            cout<<"Enter the starting city: ";
            cin>>StartCity;
            cout<<"\nEnter the ending city: ";
            cin>> EndCity;
            cout<<"\nEnter the name of the file: ";
            cin>> fileName;

        break;

Thank You.

FYI: You are NOT getting "undefined reference error" when compiling.
These happen during the linking stage NOT the compiling stage.

Do the linking correctly to fix the problem.
Link to the needed object file/library.

NOTE: If you want more help post the errors!
