Re: [lwip-users] where could I find the definition of MEMP_PBUF_POOL used in pbuf.c?

[kanprin]

thank you so much simon, yes , I did mixed the 2 versions ,
but I compiled the lwip 1.3.0 source code with gcc 3.4.3 without any
changes,
then the compiler told me that the MEMP_PBUF_POOL not defined.
is my complier version too old?

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.

Simon
