[reSIProcate-users] Linker errors when linking with resip

[Andrew Wood <ajwood@xxxxxxx>]

Ive built the library and ended up with 4 .a files: libares libdum 
libresip and librutil.

I guess the bulk of the stack is in libresip but what are the others. 
Ive tried linking against them all but Im getting errors such as:

../lib/resiprocate-1.4.1/lib/lib/libresip.a(DnsResult.o): In function 
`resip::DnsResult::skipDNSQuestion(unsigned char const*, unsigned char 
const*, int)':
/home/andrew/xswitch/lib/resiprocate-1.4.1/resip/stack/DnsResult.cxx:679: 
undefined reference to `ares_expand_name'

resip::ExternalDnsHandler*, void*)':
/home/andrew/xswitch/lib/resiprocate-1.4.1/rutil/dns/AresDns.cxx:276: 
undefined reference to `ares_query'

Which suggests to me libares.a isnt being found? Though Im not sure what 
libares is and a Google search didnt enlighten me.
Which ones do I need to link against, am I missing something?

Thanks
Andrew
