Subject Re: [users@httpd] Help building mod_auth_ldap.o against the netscape/mozilla SDK
Date Wed, 12 Oct 2005 14:28:47 GMT

Marc,

It's been a few weeks, so I'm going over my set of docs and hopefully I
didn't miss anything...

a) Make sure the SDK works if you compiled it.  I did compiled the
Mozilla SDK under RedHat but used a binary distribution for Solaris
(oddly enough made by RedHat - http://ftp.redhat.com/pub/redhat/ldapsdk/ )

b) Patch srclib/apr-util/includes/apr_ldap.h.in to enable Mozilla's SDK

c) Patch modules/experimental/util_ldap.c to implement TIMEOUT when
using the Mozilla SDK

d) Make sure you set up LD_LIBRARY_PATH or set up crle (under Solaris)
or ld.conf (linux) to include the SDK location (I use /usr/local/ldapsdk5)

e) Use the following config:

    ./configure --prefix=/usr/local/apache2 \
    --with-perl=/usr/local/bin/perl \
    --with-berkeley-db=/usr/local/BerkeleyDB.4.3 \
    --with-ssl=/usr/local/ssl -with-dbm=db43 \
    --with-ldap \
    --with-ldap-lib=/usr/local/ldapsdk5/lib \
    --with-ldap-include=/usr/local/ldapsdk5/include \
    --enable-auth-ldap --enable-ldap --enable-ssl \
    --enable-mods-shared=most

Adjust the above as needed (ie if you don't use Berkeley DB).  About the
warning, I also got it, but it still compiled. 
Note sure if you typed it back or you actually had a typo when running
configure:

    --with-ldap-lib=h-ldap-include=/usr/include/mozilla-1.7.12/ldap

Should be (besides the typo, check to make sure the libs are in ./lib
and headers in ./include):

    --with-ldap-lib=/usr/include/mozilla-1.7.12/ldap/lib \
    --with-ldap-include=/usr/include/mozilla-1.7.12/ldap/include

Note that there's a patch to util_ldap.c that was backported to v2.0.55,
but not sure if my patch for TIMEOUT or the other one to enable the SDK
would work.

Ricardo.
