Re: Compiling Samba against OpenLDAP 2.0.27

[Jean-Rene Cormier <jean-rene.cormier@cipanb.ca>]

The problem I have is not really the compilation process, when I run
configure it doesn't find the LDAP libraries so when I run make it'll
compile but without LDAP support. I searched all morning for a solution
and haven't found one yet. Though I think the problem is that the
OpenLDAP shared libraries don't link against the liblber and libresolv
cause when you do a ldd -r libldap.so they're not there and you get a
bunch of undefined symbol about stuff that are related to those
libraries and when I compile my small test C file and needed to link it
with those 2 libraries. I need a way to link the shared libraries to
liblber and libresolv when I compile them though I have no idea how to
do that...

I think your compilation problems are similar to my problems but you
could always edit the Makefile and add -lber (and maybe -lresolv too) to
LIBS to see what you get. In Samba 2.2.X I had to add -lresolv to LIBS
in the Makefile so Samba would work with LDAP.
