dovecot - Jan 2013 - Define custom ldap libraries when building Dovecot

Hello,

I would like to compile Dovecot using custom ldap libraries, located at 
a particular custom system location.

How should I alter the config process to specify that the include dir is 
"/usr/local/openldap/include" and the lib dir is 
"/usr/local/openldap/lib64" and not the standard ones (/usr/include/
and
/usr/lib64/ respectively) on RHEL/CentOS 5 (x86_64). Note that all of 
the above files/folders exist on the file system at the same time.

The idea is to build dovecot against current openldap v2.4.x libraries 
and not against the available (by the OS) ancient openldap v.2.3.x libs.

Please, advise.

Thanks,
Nick

Clarification 1: I am trying to compile Dovecot 2.1.13.

Clarification 2: The custom include (if needed) and lib dirs are for 
OpenLDAP-linking only. All other required includes/libraries are to be 
found at the standard system locations.

So, how should I declare them?

Thanks and Regards,
Nick

Sorry, I got it. According to http://wiki2.dovecot.org/CompilingSource I 
should use:

CPPFLAGS="-I/usr/local/openldap/include" 
LDFLAGS="-L/usr/local/openldap/lib64 -lldap -llber" ./configure

I found (coincidentally) that it also works simply with 
"LDFLAGS="-L/usr/local/openldap/lib64" but I guess it is more
correct to
use the full syntax: LDFLAGS="-L/usr/local/openldap/lib64 -lldap
-llber"
(or even "... -lldap" only). However, I can't tell the real
difference.

If you can shed some light on it, that would be very useful to me.

Thanks and regards,
Nick

Check the binaries with ldd to make sure they are loading the expected 
libraries at run-time.
