[reSIProcate] Failed to compile resip for Android when IPv6 enabled.

[Herbert Karajan <boost.regex@xxxxxxxxx>]

I'm using "./build/android-custom-ndk" to compile the resip 1.9.7 for Android,

It's compile successfully for IPv4, but if I added the "--enable-ipv6" option to "android-custom-ndk":

./configure \

--libdir=/libs/${MOD_NAME} \

--host=${CROSS_COMPILE} \

--with-sysroot=${SYSROOT} \

--enable-android \

--enable-ipv6 \

--with-ssl \

"$@"

I got below error:

======================================================

ares_init.c: In function 'init_by_defaults_andriod_nameservers':

ares_init.c:496:78: error: 'struct in6_addr' has no member named 's_addr'

ares_init.c:459:9: warning: unused variable 'prop_name' [-Wunused-variable]

ares_init.c: At top level:

ares_init.c:1210:12: warning: 'find_server6' defined but not used [-Wunused-function]

make[1]: *** [ares_init.lo] Error 1

=================================================

I'm tried to fix it, edit the ares_init.c, in line 496:

change rc = inet_pton(AF_INET6, props_dns[i], &channel->servers[j].addr6.s_addr);

to 

rc = inet_pton(AF_INET6, props_dns[i], &channel->servers[j].addr6.s6_addr);

Then got another error:

How to fix the errors?
