[PHP-INSTALL] How to compile LDAP Extension for PHP

Hey guys,

I'm trying to build PHP from source, but when I run ./configure with
all the extensions I want to build, I get this:

checking for LDAP support... yes, shared
checking for LDAP Cyrus SASL support... no
checking size of long int... 8
checking for 3 arg ldap_set_rebind_proc... yes
checking for ldap_parse_result... no
checking for ldap_parse_reference... no
checking for ldap_start_tls_s... no
checking for ldap_bind_s... no
configure: error: LDAP build check failed. Please check config.log for
more information.

I installed LDAP 2.4.40 and 2-devel to my Ubuntu 14.04 for this, but
it keeps saying that.

Any ideas how I can fix that?

Thanks
