Symbol referencing error

fromatz · #1 (**permalink**) 03-13-2008

Hey everyone, I can't figure out this symbol referencing error after looking at it for the longest time, and I figured some fresh eyes might be able to point something out I am overlooking.

Undefined first referenced
symbol in file
Player::Player() /var/tmp/ccqbgWea.o
ld: fatal: Symbol referencing errors. No output written to a.out
collect2: ld returned 1 exit status

I've looked at all my files and Player() is declared in the Player class. And in my player.cpp file (contains implementations of public member functions of Player) I have included "player.h" (stores my declaration of the class)

I know my battleground.h and .cpp are not complete but it should still compile fine. I know once I add a constructor in for Battleground it will also give me another symbol referencing error like Battleground::Battleground()

I compile using: g++ pvpranks.cpp

Here is the code if it will help:

battleground.h

Code:

#include "player.h"

class Battleground
{
private:
    Player bgPlayers[40];
public:

};

battleground.cpp

Code:

#include "battleground.h"
using namespace std;

player.h

Code:

class Player
{

private:

    char pname[13];
    char pserver[50];
    char prace[10];
    char pclass[8];
    int pkillingblows;
    int phonorkills;
    int pdeaths;
    int phonorgained;
    int pfaction;
    int prank;
    int pdamage;
    int phealing;
    int pflagcaps;
    int pbasesassaulted;
    int pflagreturns;
    int pbasesdefended;

public:

    Player();
    void set_pname(char pn[]);
    void set_pserver(char ps[]);
    void set_prace(char prac[]);
    void set_pclass(char pc[]);
    void set_pkillingblows(int pkb);
    void set_phonorkills(int phk);
    void set_pdeaths(int pde);
    void set_phonorgained(int phg);
    void set_pfaction(int pfa);
    void set_prank(int pran);
    void set_pdamage(int pda);
    void set_phealing(int ph);
    void set_pflagcaps(int pflagc);
    void set_pbasesassaulted(int pbasesa);
    void set_pflagreturns(int pflagr);
    void set_pbasesdefended(int pbasesd);

};

player.cpp

Code:

#include "player.h"
using namespace std;

Player::Player()
{

    pname = "\0";
    pserver = "\0";
    prace = "\0";
    pclass = "\0";

    return 0;

Hello,

I think you need to replace [in Player::Player()]:
pname = "\0";
to something like this:
pname[0]='\0';
etc.
