[Dev-C++] Compilation of multiple files

[Jan M. <jan...@vo...>]

Hello,

I have problems with compiling using gcc in Dev-C.

I am trying to compile
two .c and two .h files.

In main.h I have preprocesor commands:

#ifndef __stdio_h__
#include<stdio.h>
#define __stdio_h__
#endif
/*  and the similarly with standard .h headers. */
#ifndef __bet_list_h__
#include "bet_list.h"
#define __bet_list_h__
#endif
#ifndef __bet_list_h__
#include "bet_list.h"
#define __bet_list_h__
#endif


In main.c and bet_list.c I have:

#ifndef __main_h__
#include "main.h"
#define __main_h__
#endif


The output from make is:

gcc main.c bet_list.c -o out_exe

Anyone knows where is an error.
I have tried to do it
using just simple #include, without the definition
the preprocesor variables but it doesn't work neither.

Thank you very much
