Unkown type name "Enemy" error after including all headers in C -

-

i'm developing game sdl 2.0 in c , have following problem: after including needed .h files on each file, compiler shows error (unknown type name 'enemy') on shoots.h, have function parameter of type enemy declared on enemy.h.

the header files think i'm getting error bullet.h, enemy.h, mobs.h, , shoots.h. (there more sdl.h)

bullet.h

#ifndef bullet_h_included #define bullet_h_included #include "sdl.h"  typedef struct bullet *bullet;  #endif // bullet_h_included

enemy.h

#ifndef enemy_h_included #define enemy_h_included #include "sdl.h" #include "shoots.h"  typedef struct enemy *enemy;  #endif // enemy_h_included

mobs.h

#ifndef mobs_h_included #define mobs_h_included #include "enemy.h"  typedef struct enemylist *enemylist; typedef struct enemyposition *enemyposition;  #endif // mobs_h_included

shoots.h

#ifndef shoots_h_included #define shoots_h_included #include "sdl.h" #include "player.h" #include "bullet.h" #include "enemy.h"   typedef struct bulletlist *bulletlist; typedef struct bulletposition *bulletposition;  void initenemyshoots(bulletlist l, bulletposition p, player pl, enemy e);  #endif // shoots_h_included

struct enemy declaration on enemy.c

struct enemy {     sdl_surface *sprite;    //enemy sprite     int x, y;             //enemy position     int w, h;               //enemy hitbox     bulletlist ammo;      //enemy bullets };

those headers have declaration of functions implemented on each .c file. structs defined on own .c

that initenemyshoots have problem, since 1 of it's parameters type enemy. how can solve that?

the problem caused #including "shoots.h" in enemy.h

the #include "shoots.h" comes after #define enemy_h_included, comes before actual declaration of enemy pointer struct enemy. therefore inside shoots.h enemy not yet defined, enemy_h_included is, though shoots.h #includes enemy.h, include guards prevent being evaluated , enemy never gets defined.

the solution not include "shoots.h" inside enemy.h if don't need to.
