Re: [Dev-C++] Multiply-included header problem

Oo oi,

OK got it working... I tried the following code and it made no difference,
but I tried doing a clean build and now it's worked. The solution is basic,
but here it is anyway for those who might run into this problem at some
point.

MAIN.H
#ifndef PRAGMAONCE
#define PRAGMAONCE
int some_important_variable;
#endif


PRAGMAONCE can be renamed to whatever you feel like if you really want.

Oo oi,

I have a bit of a dilemma, albiet a seemingly simplistic one...
Say I have 3 files as follows-


MAIN.CPP
#include "main.h"

EXTRAFUNCTIONS.CPP
#include "main.h"

MAIN.H
int some_variable_important_to_lots_of_functions;


I keep getting errors that some_variable_important_to_lots_of_functions is
being redefined. I have tried the "#pragma once" solution which worked with
Visual C++ but it doesn't seem to work in Dev-C++. I tried
the following-


MAIN.CPP
#include "main.h"
int some_variable_important_to_lots_of_functions;

EXTRAFUNCTIONS.CPP
#include "main.h"

MAIN.H
extern int some_variable_important_to_lots_of_functions;


Still the same problem. Does anyone know of a solution to this? Is this some
mistake I am making, a problem with Dev-C++'s compiler, or what?
