Re: [lwip-users] errors in memp.h

[PHAM ANH THIEN]

Hi all,

For everyone looking for the solution of this issue.

The way finding exactly the error is do preprocess for memp.c file, then look at typedef enum { ...} memp_pool_helper_t; preprocessor out file, you will see exactly what the error happen.
 
For my case after i do this i see the error then i just comment out //#ifndef __LWIPPOOLS_H__
//#define __LWIPPOOLS_H__  //#endif    /* __LWIPPOOLS_H__ */ in file lwippools.h, the error does not happen anymore. 
    
Above is my solution, if anyone got difference solution please share.

Thanks a lot.

Hi Thien,

 

Sorry, I did not fix this compiling issue in lwIP source code. I am not working on this project any more so far.

Hi,

 

Can any one figure out the errors “\lwip-1.3.0\src\include\lwip/memp.h(60): error:  #29: expected an _expression_” at the line after #include "lwip/memp_std.h" in memp.h file? This error comes when I defined MEM_USE_POOLS  1 and added a head file “lwippools.h” to compile.

 

#if MEM_USE_POOLS

/* Use a helper type to get the start and end of the user "memory pools" for mem_malloc */

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"

    ) ,

    /* 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"

    )

} memp_pool_helper_t;

 

Thanks,
