[lwip-users] Include Problems

[Spies, Dominik]

Hi!

I'm working on a APIPA module and got some problems:

I have a apipa.c and a apipa.h in the core directory. apipa.h is included by etharp.c (cause of "hook" at incoming arp packets), netif.h (apipa struct in netif like dhcp) and in apipa.c.

I declared the function

 

void apipa_arp_reply(struct netif *netif, struct etharp_hdr *hdr);

 

in apipa.h and implemented it in apipa.c and calling it in etharp.c (atharp_arp_input()):

 

#if (LWIP_APIPA)
apipa_arp_reply(netif, hdr);
#endif

I must include arch/etharp.h in apipa.h that i get no error, when i do it i get following warnings:

 

Severity and Description Path Resource Location Creation Time Id
warning: 'struct etharp_hdr' declared inside parameter list FreeRTOS_02/lwip/include/lwip apipa.h line 98 1179817999628 8037

What could cause that problem?
