[lwip-users] using LWIP_DEBUG

[Alexandre Malo]

Hello,

 

  I am working with LWIP to use the SNMP Agent. And to understand more of whats going on with everything, I would really like to enable Debugging message.

 

I tried the following:

When I put: #define LWIP_DEBUG

 

I get near a thousand errors when compiling.

 

 

Here is the first few errors I get.

 

 

>>Error   : argument expected while expanding macro 'LWIP_PLATFORM_DIAG' (got 1, wanted >=2)
>>tcpip.c line 122   IAG( ("tcpip: ip_reass_tmr()\n")); if ((0x00U) & LWIP_DBG_HALT) { while(1); } } } while(0)

>>

>>Error   : undefined identifier 'LWIP_DBG_HALT'
>>tcpip.c line 122   ")); if ((0x00U) & LWIP_DBG_HALT) { while(1); } } } while(0)

>>

>>Error   : undefined identifier 'IP_TMR_INTERVAL'
>>tcpip.c line 124     sys_timeout(IP_TMR_INTERVAL, ip_reass_timer, NULL); 

>>

>>Error   : undefined identifier 'NULL'
>>tcpip.c line 258     if (tcpip_init_done != NULL) { 

>>

>>Error   : undefined identifier 'TCPIP_DEBUG'
>>tcpip.c line 274         LWIP_DEBUGF(TCPIP_DEBUG, ("tcpip_thread: PACKET %p\n", (void *)msg)); 

>>

>>Error   : undefined identifier 'TCPIP_DEBUG'
>>tcpip.c line 293         LWIP_DEBUGF(TCPIP_DEBUG, ("tcpip_thread: CALLBACK %p\n", (void *)msg));

define of LWIP_DEBUGF

 

#ifdef LWIP_DEBUG
/** print debug message only if debug message type is enabled...
 *  AND is of correct type AND is at least LWIP_DBG_LEVEL
 */
#define LWIP_DEBUGF(debug,x) do { \
                               if ( \
                                   ((debug) & LWIP_DBG_ON) && \
                                   ((debug) & LWIP_DBG_TYPES_ON) && \
                                   ((s16_t)((debug) & LWIP_DBG_MASK_LEVEL) >= LWIP_DBG_MIN_LEVEL)) { \
                                 LWIP_PLATFORM_DIAG(x); \
                                 if ((debug) & LWIP_DBG_HALT) { \
                                   while(1); \
                                 } \
                               } \
                             } while(0)

 

#else  /* LWIP_DEBUG */
#define LWIP_DEBUGF(debug,x)

define of LWIP_PLATFORM_DIAG

 

#define LWIP_PLATFORM_DIAG( x, ... ) do{ sys_debug(x);} while( 0 );
