Sure thing.
By the way, if you plan to use any of the other major libraries within
resip, here's what the link-time dependencies appear to be at the
moment:

Brilliant
it was the ordering. Thanks Adam

As you mentioned, libares is built by the project itself. (It's an
asynchronous DNS resolver library).
Librutil is a set of common utility classes used by various resiprocate
subprojects. It uses libares.
Libresip is, as you've guessed, the SIP stack itself. It uses librutil
(and, transitively, libares).
Libdum is the Dialog Usage Manager, which abstracts many User Agent
behaviors into a higher level than SIP transactions. If you're creating
a SIP User Agent, you'll want to use DUM. Libdum uses libresip and
librutil.
In most cases, link errors like you're getting come from order of
library inclusion. On your link line, you'll want to make sure the
libraries are included in the following order: libdum, libresip,
librutil, libares.

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

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
