Re: [lwip-users] SNMP module vs minimal system config

[Frédéric BERNON]

When LWIP_SNMP=0, these functions are not "declared" but simply "defined" to nothing. No, you shouldn't got any build errors. snmp.h is structured like this :

 

#if LWIP_SNMP

...

void snmp_delete_arpidx_tree(struct netif *ni, struct ip_addr *ip);

...

#else

...

#define snmp_delete_arpidx_tree(ni,ip)

....

#endif

Subject: [lwip-users] SNMP module vs minimal system config

I am trying to build a minimal config of LWIP - per the 'minimal features' page of the "makefiles" wiki page.

I have LWIP_SNMP set to zero in my lwipopts.h

There are many unsatisfied references when I link my executable.

There are quite a number of calls to snmp functions that are not 'protected' by #ifdef LWIP_SNMP. Some of these are in etharp.c (snmp_delete_arpidx_tree @ about line 180, 390; snmp_insert_arpidx_tree at about 500); also in icmp.c, ip.c, ip_frag.c, tcp.c, tcp-in.c, tcp_out.c.

Are these snmp functions needed, or can I add "#ifdef LWIP_SNMP" around them and safely turn them off?

Thanks,
Art R.
