[lwip-users] SNMP module vs minimal system config

[Rasmussen, Art N.]

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.

PS As a newbie to using mailing lists, I'd very much appreciate suggestions on how to doing simple stuff like -- how to post a reply to the list instead of emailing someone's personal email (which is the only alternative I see on the archives page, which is the recommended way to view the list according to the 'official' page at

Any pointers greatly appreciated!
