linker errors... I HATE THEM

[tomtetlaw]

THEY'RE ANNOYING! :@

This is my code:

lang.h

#pragma once

#define _ASM_START namespace _TomAsm{
#define _ASM_END   }

#define cpp_asm _TomAsm

#define _main int main(){
#define _endmain }

_ASM_START
template<typename _T>
struct _Reg{
	_T val;
	_Reg(_T _Val):val(_Val){}
};

typedef _Reg<int> _IntReg;
typedef _Reg<char> _CharReg;
typedef _Reg<float> _FloatReg;
typedef _Reg<double> _DoubleReg;
_ASM_END

instructions.h:

#pragma once

#include "lang.h"
#include "registers.h"

_ASM_START
void imov(_IntReg _Register, int _Val      );
void cmov(_CharReg _Register, char _Val    );
void fmov(_FloatReg _Register, float _Val  );
void dmov(_DoubleReg _Register, double _Val);

void iadd(_IntReg _Register, int _Val      );
void cadd(_CharReg _Register, char _Val    );
void fadd(_FloatReg _Register, float _Val  );
void dadd(_DoubleReg _Register, double _Val);

void isub(_IntReg _Register, int _Val      );
void csub(_CharReg _Register, char _Val    );
void fsub(_FloatReg _Register, float _Val  );
void dsub(_DoubleReg _Register, double _Val);

void iout();
void mcout();
void fout();
void dout();
_ASM_END

instructions.cpp:

#include <iostream>
#include "lang.h"

using namespace std;

void _TomAsm::imov(_IntReg _Register, int _Val)

void _TomAsm::mcout()
{ cout << EAX.val; }

void _TomAsm::fout()
{ cout << ecx.val; }

void _TomAsm::dout()
{ cout << ECX.val; }

registers.h:

#pragma once

#include "lang.h"
_ASM_START
_IntReg eax(0), ebx(0);
_CharReg EAX('?'), EBX('?');
_FloatReg ecx(0.0f), edx(0.0f);
_DoubleReg ECX(0.0), EDX(0.0);
_ASM_END

main.cpp:

#include "instructions.h"
#include "lang.h"
using namespace cpp_asm;

_main
	imov(eax, 0);
	iadd(eax, 4);
	isub(eax, 1);
	iout();
_endmain

I get these errors, even though I have put #pragma once in all the .h files:

I have no idea why I am getting these errors, it's not making any sense.

Can someone help me to fix these linker errors

Any help would be appreciated :)

>linker errors... I HATE THEM
The I HATE THEM -part really was too much for me, first: it adds no more extra information about your program (in other words: it's not meaningful), second: I really hate uppercase letters, especially in titles, so I've changed the title of this post as well.

Read this, maybe something useful for you:

>THEY'RE ANNOYING! :@
Another example of useless information, it won't help us, nor will it help you.
(Also, because it's in uppercase it seems like you're screaming, yelling, etc...)

>I have no idea why I am getting these errors, it's not making any sense.
Only by looking at the error messages I would say that you've (re)defined the same thing multiple times.

But I can't see where I have defined them more than once, I've only defined them in registers.h, and that's got a #pragma once in it.
