C++ :: Tile Based RPG - Undefined Reference To Class Function
Mar 13, 2014
I'm making a simple tile-based RPG and I've run into a bit of trouble when I put my code into classes.
Heres my main
#include <iostream>
#include "windows.h"
#include "math.h"
#include "time.h"
#include <string>
#include "Goblin.h"
#include "User.h"
#include "Inventory.h"
#include "Maps.h"
using namespace std;
void treasureGet();
[Code] ....
My other 3 classes have the same structure and the same error for all their functions.
This is the exact Error
undefined reference to `Goblin::goblinBattle()'|
undefined reference to `Goblin::goblinBattle()'|
undefined reference to `Goblin::goblinBattle()'|
undefined reference to `Goblin::goblinBattle()'|
undefined reference to `Inventory::inventoryOpen()'|
undefined reference to `Goblin::Goblin()'|
undefined reference to `User::User()'|
undefined reference to `Inventory::Inventory()'|
undefined reference to `Maps::Maps()'|

I'm making a program that's essentially a Text-Based Fire Emblem game; it runs calculations and rolls dice and has all sorts of Goodies. However, I have hit a block to the tune of
#ifndef ITEM_H
#define ITEM_H
class Item
{
[Code]....
Up Until I called up a Sword object, it worked fine. But when I compiled it, I got an Undefined Reference to Item::Item() error in Line 8 of Weapon.cpp.

Everything seems to be in order and I know my code still has mistakes. I'm just trying to get it to compile and it won't allow it. I've narrowed it down to when I call the functions in main but beyond that I have no clue.
#include <iostream>
#include <cstring>
using namespace std;
void getSize(int num);
void getSpace(int num, int ptr);
void inputData();
void printData();
void destroy();
const int BIG_NUMBER = 100;

So I have a really strange problem occurring...
First, here are the files I'm using:
//pa4.cpp wirtten by Syd Frederick
#include<iostream>
#include<string>
#include<fstream>
[Code].....
When compiling I'm getting a strange error that says :

I'm getting an undefined reference error to a function, and I can't figure out why. I have tried letting code blocks compile the files, I have tried the command line to compile it with the same results.
I looked up the error and found this from [URL]
undefined reference
Example
/tmp/cc2Q0kRa.o: In function `main':
/tmp/cc2Q0kRa.o(.text+0x18): undefined reference to `Print(int)'
collect2: ld returned 1 exit status
Meaning / Your code called the function Print, but the linker could not find the code for it in any .o file
Usual Causes
You forgot to link the .o file that contains the function
You misspelled the name of the function
You spelled the name of the function correctly, but the parameter list is different in someway
which seems to be the error I get. I have double checked all 4 and I see nothing.
The code that specifically gives me the error is:
Item *name = new Item(desc, id, weight, loc);
itemMap.addItem(name);
and the class looks like this:
class Item // Standard Items {
private:
std::string name;
std::string desc;
int id;
int weight;
int loc;
[code].....
I think everything matches up unless I'm just missing it.
Full codes are located here: [URL]
what I'm doing wrong?

I am modifying a set of static variables inside of the class's member function. The static variables are private. An example of what I'm doing is as below,
utilities.h
-----------
class utilities {
private:
static int num_nodes;
public:
void parse_details(char* );
[Code] ....
I get a compilation error in the function void utilities::parse_details(char* filename)
which says: undefined reference to `utilities::num_nodes'

I have been writing a fairly simple turn based rpg game in c++ and at the moment it has a 2d integer array for the map, which I can display using periods for the blank areas and letters for the various people in the game, and I am trying to figure out how to upgrade to a tile based display.

I'm still working on my Project and the next Problem has occured: How do I detect collisions on a tilebased map? My tiles are 16x16 and the map is based on the tutorial of [URL] ..... I really like this Approach because I can define for each tile of what type it should be (so a earth tile can be walkable and lead to a secret passage).
The first Number stands for what Kind of tile it should be (e.g. Grass, Earth, Water, Blank,...) and the number after ":" stands for the type of the tile (e.g. solid, walkable, do dmg to the Player,...).
e.g.
0:0 0:0 0:0 0:0 0:0 //No tile and walkable
0:0 0:0 0:0 0:0 0:0
0:0 0:0 0:0 0:0 0:0
1:1 1:1 1:1 1:1 1:1 //Grass tile and solid
2:1 2:1 2:1 2:1 2:1 //Earth tile and solid
It's working just fine with loading the Images, but i've got no clue about the collision. I've already read a lot of stuff on the Internet but I don't get how to Combine it the structure from above. For example lazyfoo describes the collision with one object like one wall. So how can I check the Player Position with each tile?
For now there's no camera, but I plan to implement one later...

/usr/lib/gcc/x86_64-redhat-linux/4.1.2/libstdc++.so: undefined reference to `memcpy@GLIBC_2.14'
Why is this happening and how do I fix it? I installed g++ with rpms, and all of the dependencies were handled.

I don't understand how memcpy can't be there, it's been standard for 40 years. And I'm not using memcpy in my code, it's likely coming from one of the STL containers I use.

trying to practice the object-oriented part of it by converting my java programs into c++. I believe I understand the concepts of a header file and declaring the functions in the .cpp files. I keep getting this "Undefined reference to NamedStorm::NamedStorm()" error.

I just purchased a laptop with Windows 8 and installed the portable Dev-C++ because the other one wasnt compatible with Win8.
Now im getting an error when i compile that says:
'undefined reference to 'printSpecChar(int)
when i was using Dev-C++ on Win7, i never had to use #include <stdlib.h> for system ("pause") but now I do.
Is there a setting that I need to change, or am I just missing something.....again?
Code:
#include <stdlib.h>
#include <iostream>
using namespace std;
int getNumber(int, int);
void printSpecChar(int);
void pause (double);
int main() {

I am looking to program a digital to analog converter to output voltage on 12 of the available analog channels. I am an novice-intermediate programmer but cannot seem to solve a problem with undefined references.
I downloaded Measurement Computing's "DAQ" and "Instacal" programs to allow for the USB-3105 board to be recognized. Included with instillation is the Universal Library example programs for the USB-3105 DAC.
I am running windows 7 and using Code::Blocks with a GNU GCC compiler to try and run this sample program on the board. The program is also written in C/C++
When I load the VOut01.C file from the examples it reads:
/*VOut01.C****************************************************************
File: VOut01.C
Library Call Demonstrated: cbVOut()
Purpose: Writes to a D/A Output Channel.
Demonstration: Sends a digital output to D/A 0 until a key is pressed.
Other Library Calls: cbErrHandling()
cbFromEngUnits()
Special Requirements: Board 0 must have a D/A output port.
/* Include files */
#include <windows.h>
#include <stdio.h>
#include <conio.h>
#include "..cbw.h"
[Code] ....
Afterwards all three functions are declared as:
int EXTCCONV cbDeclareRevision(float *RevNum);
int EXTCCONV cbErrHandling (int ErrReporting, int ErrHandling);
int EXTCCONV cbVOut (int BoardNum, int Chan, int Gain, float DataValue, int Options);
The program Instacal in combination with the header file is supposed to recognize the "BoardNum" and allows for the "int Chan", "int Gain", "float DataValue", and all other subsequent dependent variables to exist.
However, I am still retaining these undefined reference errors even when I used Instacal to define the variables of the board (BoardNum, int Chan, ...ect) and added the full location of the header file.
My questions are:
-Why is this section of the header file dimmed after the endif statements?
-Is this reference problem a problem with the header files directory?
-Do the declarations of the function in the header file prevent them from being access due to their names and or symbolism?
-Why are the reference errors @4, @8, or @20, and what does this mean?

Some background: I have a class, A, with members, B and C and D; I also have an array of A objects; I want to be able to have a function which takes said array and performs a certain calculation on either the B, C, or D members of each of the A objects, depending upon certain circumstances; I want to perform the same calculation regardless of which member is to be used in said calculation, such as always assigning the value 3 or multiplying the member's value by a cofactor of some sort.
My question, therefore, is: how I might do this using only one function be it a template or not?

We're assigned a project working with classes and fractions. My goal is to display a fraction in proper from based on 2 arguments passed to a class member function proper();
My strategy was to utilize the greatest common factor between the 2 arguements, then divide both the numerator and denominator by that number and then it would display.
The program actually runs, but only seems to divide the numerator and not the denominator. This in return makes my other class member functions have incorrect comparisons and sums.
Code:
#include<iostream>
#include<conio.h>
class Fraction {
friend void compare(Fraction a, Fraction b);
friend void sum(Fraction a, Fraction b);

I've been trying for more than one month to access a method found in a library called libcocosnas_static.a. I'm using Cocos2d-X version 2.0.4. The library has been used many times by my company to make games using cocos2d-1.0.1-x-0.12.0 without any problem.
This is what I've done:
1- I added the include paths of the library to both eclipse and Android.mk
2- Included the .h file using #include "NASPlatformUtil.h"
3- Added the libcocosnas_static.a file to the proj.androidobjlocalarmeabi folder
4- Added "LOCAL_WHOLE_STATIC_LIBRARIES += cocosnas_static" to the Android.mk file
5- Called the function using: NASPlatformUtil:: openUrl("http://xxx.xxx.com/");
I can right click on the function, click Open Declaration and get it without any problem, but the compiler keeps on giving me that dreaded error...
