Hi there,
I think you are mixing 2 different versions of lwIP here: the 3
occurrences of MEMP_PBUF_POOL seem to fit to lwIP v1.3.0 but in the
corresponding (and current) memp.h, the typedef enum memp_t is defined
like this:
typedef enum {
#define LWIP_MEMPOOL(name,num,size,desc) MEMP_##name,
#include "lwip/memp_std.h"
MEMP_MAX
} memp_t;
Some preprocessor magic puts the enum members together, which is why you
don't find the real definition of the enum members when searching the code.

it appears three times in the pbuf.c, but I could not reach its definition ,
where does it defined ? or which num should I define it?
in pbuf.c
line 145: p = memp_malloc(MEMP_PBUF_POOL);
line 175: q = memp_malloc(MEMP_PBUF_POOL);
line 498: memp_free(MEMP_PBUF_POOL, p);
the MEMP_PBUF_POOL must be memp_t type through memp_malloc();
memp_t is defined in memp.h as
typedef enum {
MEMP_PBUF,
MEMP_RAW_PCB,
MEMP_UDP_PCB,
MEMP_TCP_PCB,
MEMP_TCP_PCB_LISTEN,
MEMP_TCP_SEG,
MEMP_NETBUF,
MEMP_NETCONN,
MEMP_API_MSG,
MEMP_TCPIP_MSG,
MEMP_SYS_TIMEOUT,
MEMP_MAX
} memp_t;
but still no MEMP_PBUF_POOL;
regards !
