Re: [reSIProcate-users] Compiling resiprocate on iOS

[Francesco Lamonica <alienpenguin@xxxxxxxxx>]

Hi all,

upon Dmytro suggestion i changed a bit DnsUtil to return localhost,

but i still get the assert failure in SipStack::getHostAddress()

i tried recompiling resiprocate with -DUSE_CARES as per Dmytro suggestion, however i get some compilation error :

dns/AresDns.cxx:369:61: error: member access into incomplete type 'ares_channeldata'

any ideas?

Talking about problem in DnsUtil.cxx.
I did see the same problem.

I use #ifdef-ed minor modification of DnsUtil::getLocalHostName()
which does return "localhost" name. Nothing more.

I did see similar problem for iOS / Android /  W10(UWP) - sometimes
this API is slow or bugging, especially after network changes.

About SipStack::getHostAddress() - I'm not sure - please check if you
have USE_CARES #define. It is must have definition if you want to use
DNS in async way.
