[avahi] Problems compiling avahi for Android NDK project

Hi again,
Starting fresh
1) Git avahi
git clone git://git.0pointer.de/avahi.git
2) Download the Android patches:
From: http://avahi.org/ticket/354
Apply the two patches:
git am < 0001-Add-Android-support.patch
git am < 0002-Add-uninstalled.pc.in-files.patch
3) Remove the patch from avahi-core/socket.c:
Commented out the following lines:
#ifdef __BIONIC__
struct in6_pktinfo {
struct in6_addr ipi6_addr;
int ipi6_ifindex;
};
#endif
4) building the lib:
-Make sure androgenizer is built and in my path
which androgenizer
/usr/local/bin/androgenizer
-Starting with the Android.mk file provided by the patch
-Added AVAHI_TOP variable definition and commands for building the shared lib.
-<Android.mk file attached>
ndk-build or ndk-build V=1 NDK_LOG=2 APP_ABI="armeabi armeabi-v7a"
results in the same thing:
jni/Android.mk:20: warning: overriding commands for target `avahi-configure-real'
jni/Android.mk:20: warning: ignoring old commands for target `avahi-configure-real'
Install : libavahi.so => libs/armeabi/libavahi.so
Install : libavahi.so => libs/armeabi-v7a/libavahi.so
This lib is 38K and when I link my project against it all the avahi commands are unresolved references
undefined reference to `avahi_server_add_service'
undefined reference to `avahi_server_add_service'
undefined reference to `avahi_server_add_service_subtype'
undefined reference to `avahi_s_entry_group_commit'
etc...
There are no Android.mk files present in any of the Avahi subdirectories (like avahi-core etc)
So I don't think it's running androgenizer.
It doesn't seem like any sources are being compiled into the lib, 38K seems small.
Not sure how to proceed here, problem with the Android.mk file most likely?
Thanks,
Chris
