Hi,

I'm trying to port some code (KX509) to cygwin that needs to use librsolv. 
I've installed minires-devl-0.98-1, but make (of KX509) always fails with 
'undefined reference to '___res_search' and '___dn_expand':

 ...
 gcc -o kx509   -g -O2  -DUSE_KRB5 kx509.o debug.o getcert.o\
 get_kca_list.o 
 get_realm.o store_in_cc.o store_tkt.o ../lib/libkx.a -L/usr/lib -L/usr 
 -lcrypto -L/opt/krb5-1.3.1//lib -lkrb5 -lk5crypto -lcom_err
 get_kca_list.o(.text+0xf9): In function `get_kca_list':
 /opt/src/kx509/cygwin_w2k/client/../../src/client/get_kca_list.c:266: 
 undefined reference to `___res_search'
 get_kca_list.o(.text+0x174):/opt/src/kx509/cygwin_w2k/client/../../src/\
 client/get_kca_list.c:294: undefined reference to `___dn_expand'
 ...
 collect2: ld returned 1 exit status
 make[1]: *** [kx509] Error 1
 make[1]: Leaving directory `/opt/src/kx509/cygwin_w2k/client'

I've set up the lib links as follows:

 $ cd /usr/lib; ls -l libresolv* libminires.*
 -rwxrwxrwx    1 guest  Users      453200 Jan 22 11:45 libminires.a
 -rwxrwxrwx    1 guest  Users       21784 Jan 22 11:45 libminires.dll.a
 lrwxrwxrwx    1 guest  Users         135 Feb 10 12:20 libresolv.dll.a ->
 /usr/lib/libminires.dll.a
 lrwxrwxrwx    1 guest  Users       127 Feb 11 13:22 libresolv.a -> 
 /usr/lib/libminires.a

and the libraries seem to have the required functions:

 $ nm -s libresolv.dll.a | grep ___res_search
 ___res_search in d000016.o
 __imp____res_search in d000016.o
 00000000 T ___res_search
 00000000 I __imp____res_search

 $ nm -s libresolv.a | grep ___res_search
 ___res_search in minires.o
 00001b78 T ___res_search

So how can I make gcc find ___res_search and ___dn_expand? Did I miss 
something?

regards

King Lung Chiu
