Compiling Avahi on a FreeBSD-6.1-ish machine fails in the autoipd directory
with the following complaint:
main.c: In function `open_socket':
main.c:665: error: `PCAP_D_IN' undeclared (first use in this function)
main.c:665: error: (Each undeclared identifier is reported only once
main.c:665: error: for each function it appears in.)
main.c:687: warning: passing arg 3 of `pcap_compile' discards qualifiers from pointer target type
gmake[2]: *** [avahi_autoipd-main.o] Error 1
I used the following patch to get around it:
