Hi avahi people,

I'm trying to compile avahi for an embedded device and I would like to only have the avahi-core library. I've disabled everything else as far as I could tell. There doesn't seem to be a ./configure option for IPV6 so aside from altering the code, I don't think there's any way for me to prevent the compile-time error further below.

This happens both with 0.6.15 and 0.6.12, and likely the versions in between.

My ./configure line is here:

CC=arm-linux-gcc ./configure --build=i686-pc-linux-gnu --host=arm-9tdmi-linux-gnu --prefix=$PWD/../avahi-0.6.12-arm  --disable-glib  --disable-qt3 --disable-qt4 --disable-gtk  --disable-dbus  --disable-expat  --disable-gdbm --disable-libdaemon  --disable-python  --disable-pygtk --disable-python-dbus --disable-mono --disable-monodoc  --disable-doxygen-doc  --disable-manpages --with-distro=debian

I just grepped for IPV6_V6ONLY recursively through /usr/include, and i found it in:

/usr/include/linux/in6.h

/usr/include/linux/in6.h:172:#define IPV6_V6ONLY

Is this a known bug? Would it fix the problem by simply adding

#ifdef ... ipv6 code #endif

code to the function / header files (socket.c/h i guess) ? Is there some reason why IPv6 is always built?

Many thanks. I'm going to patch this myself for now, should I send you the diff?

The Avahi configure script includes many checks for optional features, and bails out if the prerequisites for any of those optional features is missing.

It would be nice if after detecting that the prerequisites aren't available, avahi could disable the optional feature.

This makes it difficult to produce a single set of commands that will build avahi on a variety of platforms (as a buildscript like jhbuild would need to do), unless I explicitly disable all the optional features that may or may not be available on the target system.

i18n labels should be encoded with punycode instead of utf8 like on mDNS.

This touches #21 in some way

Currently, if no suitable network interface is found, local browser clients will to find locally registered services. Some people find this confusing.

It might be a good idea to make use of the loopback network interface iff no better interface is available. And if a better iface becomes available don't use "lo" anymore.

the stdb stuff already has that and the rest needs that as well.
