[lwip-users] lwippools.h, building error with memp.h

[PHAM ANH THIEN]

Dear all,

I defined MEM_USE_POOLS=1 and MEMP_USE_CUSTOM_POOLS=1 in lwipopts.h, also created lwippools.h as below

#ifndef __LWIPPOOLS_H__
#define __LWIPPOOLS_H__

/* OPTIONAL: Pools to replace heap allocation
 * Optional: Pools can be used instead of the heap for mem_malloc. If
 * so, these should be defined here, in increasing order according to
 * the pool element size.
 *
 * LWIP_MALLOC_MEMPOOL(number_elements, element_size)
 */
#if MEM_USE_POOLS
LWIP_MALLOC_MEMPOOL_START
LWIP_MALLOC_MEMPOOL(100, 256)
LWIP_MALLOC_MEMPOOL(50, 512)
LWIP_MALLOC_MEMPOOL(20, 1024)
LWIP_MALLOC_MEMPOOL(20, 1536)
LWIP_MALLOC_MEMPOOL_END
#endif /* MEM_USE_POOLS */

/* Optional: Your custom pools can go here if you would like to use
 * lwIP's memory pools for anything else.
 */
//LWIP_MEMPOOL(SYS_MBOX, 22, 100, "SYS_MBOX")
#endif    /* __LWIPPOOLS_H__ */

But when i compile i got some error messages: 

Error   : (Serious) C2291E: <_expression_> expected but found ')'
memp.h line 60   

Error   : (Serious) C2291E: <_expression_> expected but found ')'
memp.h line 69   

This is memp.h file where error message was found

typedef enum {
    /* Get the first (via:
       MEMP_POOL_HELPER_START = ((u8_t) 1*MEMP_POOL_A + 0*MEMP_POOL_B + 0*MEMP_POOL_C + 0)*/
    MEMP_POOL_HELPER_FIRST = ((u8_t)
#define LWIP_MEMPOOL(name,num,size,desc)
#define LWIP_MALLOC_MEMPOOL_START 1
#define LWIP_MALLOC_MEMPOOL(num, size) * MEMP_POOL_##size + 0
#define LWIP_MALLOC_MEMPOOL_END
#include "lwip/memp_std.h"
    ) ,   //<--------------- line 60
    /* Get the last (via:
       MEMP_POOL_HELPER_END = ((u8_t) 0 + MEMP_POOL_A*0 + MEMP_POOL_B*0 + MEMP_POOL_C*1) */
    MEMP_POOL_HELPER_LAST = ((u8_t)
#define LWIP_MEMPOOL(name,num,size,desc)
#define LWIP_MALLOC_MEMPOOL_START
#define LWIP_MALLOC_MEMPOOL(num, size) 0 + MEMP_POOL_##size *
#define LWIP_MALLOC_MEMPOOL_END 1
#include "lwip/memp_std.h"
    )     //<--------------- line 69
} memp_pool_helper_t;


Anyone faced or knew how to solve it please advise!

Thanks a lot
Thien
