Re: [Libvncserver-common] [PATCH] IPv6 support for LibVNCServer, part one: accept IPv4 and IPv6 connections.

[José L. P. <on...@gm...>]

Hi all,

Just for clarification, shouldnt the ipv6 related stuff
on rfbProcessNewConnection be surrounded by the LIBVNCSERVER_IPv6 macro
verification? i tried to compile vncserver without ipv6 support and i was
having errors on "rfbCheckFds: accept".

Note, it was just tested on Android.
