I am coding a RTS game but I cant compile my dataLoader function. It gives that errors when want to call it:
//Window size
int width;
int height;
if( !dataLoader<int>( width, "settings/resolution.txt", "width" ) || !dataLoader<int>( height, "settings/resolution.txt", "height" ) )

I am wondering why ToStr throws me this error. I am using mingw64 and codeblocks.
Code:
E:JackyDocumentsCode Blocks ProjectsPerfectSimXmain.cpp|35|undefined reference to `std::string ToStr<int>(int const&)'|
Code:
for (int i = 0; i < NO_CAMS; i++) {
std::string filename("E:/Jacky/Documents/Code Blocks Projects/PerfectSimX/Data/Cam");
std::string restFileName(".cam");
filename += ToStr(i);
[Code] ....
The error is this:
#include <iostream>
using namespace std;
void add(int s);
void subtract(int d);
void multiply(int p);
void divide(int q);

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;
[code]....
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 :
/tmp/ccdt0Bf9.o: In function `main':
pa4.cpp:(.text+0x1c): undefined reference to `synopsis()'
pa4.cpp:(.text+0x1e7): undefined reference to `execute(std::basic_string<char, std::char_traits<char>, std::allocator<char> >)'

I am currently working on a code, but I keep getting a error as follows:

[Linker error] undefined reference to 'getStateTax(double)'
[Linker error] undefined reference to 'getFederalTax(double)'

[Linker error] undefined reference to 'getWithHoldingAmount(double)'
I have been trying to debug this error for hours and I am completely stumped....

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.

what I'm doing wrong?
Why I keep getting the error: "In function main: [linker error] undefined reference to readBook(BookData)" ....
main.cpp :
Code:

#include "BookData.h"

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 <string>
#include "Goblin.h"
#include "User.h"
#include "Inventory.h"
#include "Maps.h"
using namespace std;
void treasureGet();

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()'|

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'
compiler: g++
Due to the nature of this requirement, I've made a very minimal example, which would adequately solve my issue, without resorting to use of pointers or copy constructors.
Basically I'm trying to pass an object as a reference to the template function, rather than a copy as it's seeing. I'm needing to do this without editing Obj::Call to accommodate a reference as its first parameter, as it'd break other calls.
You'll notice in the following code the object will be destroyed upon passing, while the object defined is still in-scope due to the infinite end loop.
#include <iostream>
#include <string>
using namespace std;
class Obj {
public:
string name;
[Code] ....
In the past I tried ref(), which appeared to stop this happening, however it created a blank copy of the object instead.

The problem with the code is on line 14 and says undefined reference to `push(int)
Code:

using namespace std;
void push(int n);
int pop(int &n);

glibc-headers-2.5-34
glibc-devel-2.5-34

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);

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'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...
I'm trying to implement a simple template array class, but when i came into the operator< i actually have to use a template :
my code is something like :
template<typename _Type, std::size_t _Size>
class array {
public :
[Code] ......
but i am having an error of shadows template param 'class _Type' is it w/ the name conflict between the array template parameter and the function template parameter ?
I have a function:
template<class Iterator, class T>
void a(Iterator, Iterator, const T&);
and I want to be able to simplify calls to 'a' with calls like
a(someIteratableContainer);
instead of having to call:
a(someIteratableContainer.begin(), someIteratableContainer.end(), valueOfTheContainersElementType);
I also want to be able to generalize the function to handle any of the standard iteratable contains: array, vector, deque, whatever.
I was under the impression I could write:
template<template<class T> class U> a(U<T>& container) {
a(container.begin(), container.end(), g(T()));
}
where 'g()' returns an object of the element type. However, the compiler is claiming, no matter how I write a call to the overload, the original template is selected and/or the overload is invalid, depending on the various ways I attempt to write said overload.
