dovecot - Oct 2006 - autoconf check for ldap not linking with -lber

Maybe not a big deal, but generally you (used to?) link against both:

configure:31276: checking for ldap_init in -lldap
configure:31311: gcc -o conftest -std=gnu99 -I/usr/local/include -Wall -W -Wmiss
ing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat
=2 -Wbad-function-cast -I/usr/sfw/include    -L/usr/local/lib conftest.c -lldap
   -lsocket -lnsl -lrt -lsendfile >&5
Undefined                       first referenced
  symbol                             in file
ber_sockbuf_io_readahead            /usr/local/lib/libldap.so
ber_sockbuf_alloc                   /usr/local/lib/libldap.so
ber_sockbuf_io_fd                   /usr/local/lib/libldap.so

But could be special situation as my LDAP version is fixed, due to production 
environment using it. It also failed when OpenLDAP was linked against OpenSSL, 
since it does not try with the SSL libraries.

If anyone cares, I needed:

from: LIBS="-lldap $LIBS"

to:   LIBS="-lldap -llber -lresolv $LIBS"

to compile, that's without SSL support in OpenLDAP.

No, I've never even heard of lber before.

I think usually the linker links it with automatically..:

~/cvs/m/dovecot/src/auth% rm dovecot-auth 
~/cvs/m/dovecot/src/auth% make |grep lber
~/cvs/m/dovecot/src/auth% ldd dovecot-auth|grep lber
        liblber.so.2 => /usr/lib/liblber.so.2 (0xb7b75000)
