it isn't
[root@corbeau /usr/local/src/openldap-2.1.8]
$ ldd ./servers/slapd/back-bdb/.libs/back_bdb.so
libc.so.6 => /lib/i686/libc.so.6 (0x42000000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)
Here's what I see in Makefile.in, but I don't what to change ?
[root@corbeau /usr/local/src/openldap-2.1.8/servers/slapd/back-bdb]
$ vi Makefile.in
...
shared_LDAP_LIBS = $(LDAP_LIBLDAP_R_LA) $(LDAP_LIBLBER_LA)
NT_LINK_LIBS = -L.. -lslapd $(@BUILD_LIBS_DYNAMIC@_LDAP_LIBS)
UNIX_LINK_LIBS = $(@BUILD_LIBS_DYNAMIC@_LDAP_LIBS)
