Hi !
Here is an example of source with the project file for rhide. This example
work only if you don't setup variables with values (like a=2;).
In this example, this is not really a problem, but my program needs to
assign values to var in header files.

source of header f.h :
#include <stdlib.h>
#include <stdio.h>
#include "allegro.h"

#ifndef FONC_H
#define FONC_H

// here
int d_a=10;
int d_b=11;

extern int calcab(int a, int b);

#endif
----------------

source of f.c :
#include "fonc.h"

int calcab(int a, int b)
{
 return a*b+d_a;
}
--------------

source of main.c :
include <stdlib.h>
#include <stdio.h>

#include "allegro.h"
#include "fonc.h"


int calcabi(int a, int b)
{
 return (d_a*a)+(d_b*b);
}

int main()
{

 int r;

 allegro_init();
 install_keyboard();

 printf("\nBonjour !");
 r=calcab(d_a,d_b)+calcabi(7,8);
 printf("%d*%d=%d",d_a,d_b,r);

 readkey();

 set_gfx_mode(GFX_VGA, 320, 200, 0, 0);
 set_pallete(desktop_pallete);
 textout_centre(screen, font, "Hello, world!", SCREEN_W/2, SCREEN_H/2, 255);
 readkey();
 return 0;
}
