C/C++ :: Display Contents Of Binary Tree In Per-level Format - Undefined Reference
Oct 5, 2014
I am coding in C++ an implementation of BTree Insertion. I want to display the contents of the Tree in a per-level format. After writing functions and trying to run. I get the error Undefined reference.
// C++ program for B-Tree insertion
#include<iostream>
using namespace std;
// A BTree node
class BTreeNode{
int *keys; // An array of keys
int order; // Minimum degree (defines the range for number of keys)
BTreeNode **child; // An array of child pointers
int size; // Current number of keys

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 :

/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.
glibc-headers-2.5-34
glibc-devel-2.5-34
libstdc++-devel-4.1.2-44
gcc-4.1.2-44
gcc-c++-4.1.2-44
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'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 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?

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()'|

My homework assignment is to create a 2 dimensional array that displays in a 10x10 table-like format after completing this assignment i must:
a) sum of each row
b) sum of each column
c) sum of every other row (vice versa with columns)
d) add diagonally
f) change the row to columns
what i have so far is
#include <iostream>
#include <iomanip>
using namespace std;
int main() {
const int row = 10;
const int col = 10;
[Code] ....
Furthermore, what ive tried is to do total = total + x[r][c] within (for c= 0...)
But when it is outputted it continues to add the total from before (which of course is a looping error ive made)
How to add and subtract elements within arrays?
