Re: [lwip-users] MEMP_POOL_256 undeclared when enabling custom pools

I must of corrupted things while messing around with lwip makefiles.  

I redid all my steps from a clean lwip2 checkout and everything compiles.

Thank again for the help.

Subject: [lwip-users] MEMP_POOL_256 undeclared when enabling custom pools

 

Hi

I am trying to use the latest lwip2.0 and use it with custom pools.  I am using the following wiki document and followed it to the letter.

http://lwip.wikia.com/wiki/Custom_memory_pools

I added in lwipopts.h:

#define MEM_USE_POOLS                   1

#define MEMP_USE_CUSTOM_POOLS           1

And created lwippools.h

LWIP_MALLOC_MEMPOOL_START

LWIP_MALLOC_MEMPOOL(50, 256)

LWIP_MALLOC_MEMPOOL(50, 512)

LWIP_MALLOC_MEMPOOL(50, 1512)

LWIP_MALLOC_MEMPOOL_END

After doing this I am running into the following error when trying to compile lwip2.0 with the microblaze compiler (gcc).

"src/include/lwip/priv/memp_priv.h:101:42: error: 'MEMP_POOL_256' undeclared here (not in a function)"

How does one fix this issue.  

Thanks in advance.
