libspf2.so: undefined reference to `res_ninit'

During the process of fixing many different errors in libspf2-1.2.5

I came up to the following step:
----
Making all in spfquery
source='spfquery.c' object='spfquery.o' libtool=no
depfile='.deps/spfquery.Po' tmpdepfile='.deps/spfquery.TPo' depmode=gcc
/bin/sh ../../config/depcomp gcc -DHAVE_CONFIG_H -I. -I. -I../..
-I../../src/include -I../../src -I/usr/local/include -pthread -lbind
-Wall -c spfquery.c
gcc: -lbind: linker input file unused since linking not done
/bin/sh ../../libtool --mode=link gcc -pthread -lbind -Wall
-L/usr/local/lib -o spfquery spfquery.o ../../src/libspf2/libspf2.la -lintl
mkdir .libs
gcc -Wall -o .libs/spfquery spfquery.o -pthread -L/usr/local/lib
../../src/libspf2/.libs/libspf2.so -lbind -lintl -Wl,--rpath
-Wl,/usr/local/milter/lib
../../src/libspf2/.libs/libspf2.so: undefined reference to `res_ninit'
../../src/libspf2/.libs/libspf2.so: undefined reference to `res_nclose'
*** Error code 1

Stop in /mnt/disk/A/com/libspf2-1.2.5/src/spfquery.
*** Error code 1
----

It seems strange enough for me because:
----
# nm libbind.a | grep res_ninit
U __res_ninit
U __res_ninit
U __res_ninit
U __res_ninit
U __res_ninit
U __res_ninit
U __res_ninit
U __res_ninit
U __res_ninit
U __res_ninit
U __res_ninit
00000000 T __res_ninit
----

But the linker ignores this fact permanently as shown above.
Can anybody prompt - maybe I forgot something?

On FreeBSD, installing bind from the isc sources created the needed library
in a subdirectory of the installation directory, but that library was not
installed to the system doing a "make install". (!)
I manually installed it and that fixed the linking errors.

The library (libbind.la) was in the lib/bind subdirectory of the install directory.

[on my system, in /usr/local/bind/bind-9.2.4rc4:]
./lib/bind/.libs/libbind.a
./lib/bind/.libs/libbind.la
./lib/bind/libbind.la

It's not exact so - I installed /usr/local/lib/libbind.a (libbind.la was
not created)
and after that I got the result as signed in previous message.

Unfortunately I don't have a BSD box to test this kind of thing on.
However, one of our sub-projects is to write an internal DNS packet
generator/library, since the majority of the compilation/linkage errors
we see are due to the inability to link against thread-safe DNS
libraries. Since DNS is almost a non-moving standard, it will make sense
just to write a packet generator.

Expect this around 1.2.10.

While looking at this, I noticed that libspf2 has checks for
#if HAVE_DECL_RES_NINIT
on several places in the code, and reverts to using res_init() and
res_close() instead here (which will work on a stock FreeBSD system
without libbind installed).

However these #if's don't appear everywhere, and I wonder why:
Is libspf2 supposed to work with plain res_init()?
If so, please include a few more #if HAVE_DECL_RES_NINIT checks.


Ciao,
Johan

The attached patch makes it compile on my FreeBSD (current) machine.
