Re:RE: RE: [lwip-users] how can I do when I want to set MEM_USE_POOLS = 1?

I has set MEM_USE_POOLS and MEMEP_USE_CUSTOM_POOLS enable, and add the file lwippools.

 

 

compiler code, It can't find MEMP_POOL_START and MEMP_POOL_END in the funtion mem_malloc() of the file mem.c, it should be change MEMP_POOL_START to MEMP_POOL_FIRST and change MEMP_POOL_END to MEMP_POOL_LAST, MEMP_POOL_FIRST and MEMP_POOL_LAST defindes in the memp.h.

I realize this was never adequately documented. … I have updated the article on lwipopts.h to explain more about the MEM_USE_POOLS and MEMP_USE_CUSTOM_POOLS options.

I'm set MEM_USE_POOLS = 1, not MEMP_USE_CUSTOM_POOLS, maybe it is some difference?

Here is what Jared (I think he invendet the new memp settings code)

wrote about it on lwip-devel:

As far as setting up a set number, you can define as many as you like.

So:

* #define MEMP_USE_CUSTOM_POOLS 1 to turn on the custom pools.. 

* Create a "lwippools.h" in the same directory as your "lwipopts.h"

file (doesn't really have to be in the same directory, but it may as

well be). Here is one I put together for an example... did I upload it

to the CVS somewhere?

/* OPTIONAL: Pools to replace heap allocation

* Optional: Pools can be used instead of the heap for mem_malloc. If so,

these

* should be defin!
 ed 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(20, 256)

LWIP_MALLOC_MEMPOOL(10, 512) LWIP_MALLOC_MEMPOOL(5, 1024)

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, sizeof(struct sys_mbox_struct), "SYS_MBOX")

LWIP_MEMPOOL(SYS_SEM, 12, sizeof(struct sys_sem_struct), "SYS_SEM")

Hi,

    I'm test LWIP When !
 I put ME
M_USE_POOLS = 1, then compiler code, some

of errors in memp.h. What do I do when I want to set MEM_USE_POOLS = 1?

or is it some error in the file memp.h?

Thanks.
