Thread: how to ordered const structs

Hello every one.
I'm developing a menu system for a embedded device. i designed a struct and some core functions. i need all menu items in ordered some way. but when i try to compile this code faced with error { initializer element is not a constant }. here is sample code with comments. how can i solve this problem.
(complier gcc)

Code:

#include <stdio.h>

typedef struct _MENUITEM {			// this struct have details of menu items
	unsigned char* title;			// title bar
	struct _MENUITEM * topItem;		// if this item have parent, pointer of this parent, if dont have 0
	struct _MENUITEM * subItems;		// if this item have sub items, pointer of first item, if dont have subitems 0
} _menuItem; 

#define ITEM_1_IND	0	// order of menu items
#define ITEM_2_IND	1
#define ITEM_3_IND	2
#define ITEM_4_IND	4
#define ITEM_5_IND	5
#define ITEM_6_IND	6
#define ITEM_7_IND	8

const _menuItem itemOne;	// definitions
const _menuItem itemTwo;
const _menuItem itemThree;
const _menuItem itemFour;
const _menuItem itemFive;
const _menuItem itemSix;
const _menuItem itemSeven;

_menuItem * const itemsArray[] = {	// now i can reach items ordered
								&itemOne,
								&itemTwo,
								&itemThree,
								0,
								&itemFour,
								&itemFive,
								&itemSix,
								0,
								&itemSeven,
								0};
// error in this line. {initializer element is not a constant}
const _menuItem itemOne =		{"one",		0,		itemsArray[ITEM_2_IND]};
// one have no parent item and it have subitem(s). this items start from second(ITEM_2_IND=1) item of itemsArray
const _menuItem itemTwo =		{"two",		itemsArray[ITEM_1_IND],		itemsArray[ITEM_4_IND]};
const _menuItem itemThree =		{"three",	itemsArray[ITEM_1_IND],		itemsArray[ITEM_7_IND]};

int main(void) {
	
	printf ("hello");
	return EXIT_SUCCESS;
}

thanks Salam. it's ok now
