P1: Making and Installing the OpenLDAP Distribution

This file provides brief instructions on how to build and install
OpenLDAP on UNIX (and UNIX-{{like}}) system.  For other systems,
please consult {{The OpenLDAP Administrator's Guide}}
{{URL:http://www.openldap.org/devel/admin/}}.

It is recommended that you read, or at least skim through, ALL of
the instructions in this file before attempting to build the
software.

It is also recommended your review
{{The OpenLDAP Administrator's Guide}}
({{URL:http://www.openldap.org/devel/admin/}}) and
the {{Frequently Asked Questions}} ({{URL:http://www.openldap.org/faq/}})
pages, in particular the
{{Installation section}} ({{URL:http://www.openldap.org/faq/index.cgi?file=8}})
and
{{Platform Hints}} ({{URL:http://www.openldap.org/faq/index.cgi?file=9}})
should be examined.


P2: Making and Installing the OpenLDAP Distribution

^ Unpack the distribution and change directory:

E:	% tar xfz openldap-VERSION.tgz
E:	% cd openldap-VERSION

.(replacing {{EX:VERSION}} with the appropriate version string).  If
you are reading this file, you probably have already done this!


+ Type:

E:	% ./configure --help

.to list available configuration options.   A description of
these options is provided in the 'CONFIGURE OPTIONS' section
below.

.The {{EX:configure}} script uses environmental variables for
determining compiler/linker options.  See the 'USING ENVIRONMENT
VARIABLES' section for commonly used settings.

.These environment variables are used: 

>	CC		C compiler	gcc
>	CFLAGS		C flags		-ansi
>	CPPFLAGS	cpp flags	-I/path/include -Ddef
>	LDFLAGS		ld flags	-L/usr/local/lib
>	LIBS		libraries	-llib
>	PATH		command path	/usr/local/bin:/usr/bin:/bin

.See the 'USING ENVIRONMENT VARIABLES' section for information
on how to use the variables. 

+ Configure the build system

E:	% [env settings] ./configure [options]

.If all goes well, the {{EX:configure}} script with automatically
detect the appropriate settings.  However, you may need to
specify options and/or environment variables to obtain desired
results.

+ Build dependencies

E:	% make depend

+ Build the system

E:	% make

.If all goes well, the system will build as configured.  If not,
return to step 3 after reviewing the configuration settings.  You
may want to consult the {{Platform Hints}} subsection of the {{FAQ}}
if you have not done so already.

+ Test the standalone system

.This step requires the standalone LDAP server, {{slapd}}(8),
with {{LDBM}} support.

E:	% make test

.If all goes well, the system has been built as configured.  If not,
return to step 4 after reviewing your configuration settings.  You
may want to consult the {{Installation}} section of the {{FAQ}}
if you have not done so already.

+ install the binaries and man pages.  You may need to be {{superuser}}
to do this (depending on where you are installing things):

E:	% su root -c 'make install'

+ That's it!

See the {{Administrator's Guide}} and the manual pages for the
individual applications for configuration and use information.
You may also want to edit the configuration files used by the
various components.  These configuration files are located in
the OpenLDAP configuration directory (normally
{{F:/usr/local/etc/openldap}}).

>	ldap.conf		client defaults
>	ldapfilter.conf		search filter configuration
>	ldapsearchprefs.conf	search object definitions
>	ldaptemplates.conf	display template definitions
>	slapd.conf		Standalone LDAP daemon
>	schema/*.schema		Schema Definitions

There are section 5 man pages for these configuration files.


P2: Building OpenLDAP For More Than One Platform

You can build OpenLDAP for more than one platform from the
same source tree.
This is accomplished by using {{make}}(1) {{EX:VPATH}} support.
If your {{make}}(1) program is old and doesn't have {{EX:VPATH}}
support, install {{BSD Make}} or {{GNU Make}}.

Follow these steps for each different platform:

^ Create a directory for the platform object files.

E:	% mkdir obj-platform

+ Change your working directory to the platform object directory.

E:	% cd obj-platform

+ Configure the build system

E:	% [env settings] ../configure --src-dir=.. [options]

. ( replace "{{F:..}}" with the appropriate path )

+ Continue as above (starting at step 6).


P2: CONFIGURE OPTIONS

Regrettably, this section has not been written (yet).  See
"{{EX:./configure --help}}" for current list of options.  For general
information about how to use "{{EX:configure}}", please read
{{F:doc/install/configure}}.


P2: USING ENVIRONMENT VARIABLES

The configure script will also use your environmental
variables for determining compiler/linker options.   This can
be used to manual specify features and compilation options.

Note[label=Warning]: Executables built in your environment may not run
in your users' environments.  The portability of executables
between environments is your responsibility.

Supported Environmental Variables:

>	CC		C compiler	cc
>	CFLAGS		C flags		-ansi
>	CPPFLAGS	cpp flags	-I/path/include -Ddef
>	LDFLAGS		ld flags	-L/usr/local/lib
>	LIBS		libraries	-llib
>	PATH		command path	/usr/local/bin:/usr/bin:/bin

* Including alternative compilers

.Use the {{EX:CC}} environment variable to tell configure to
use a specific compiler.  For example, to use {{GNU C
Compiler}} instead of the default compiler, use:

E:	% [env] CC=gcc ./configure 

.You can also use {{EX:CC}} use specific flags with the
specified compiler.  For example, to require strict
{{ANSI C}} using the {{GNU C Compiler}}, use:

E:	% [env] CC="gcc -ansi -pedantic" ./configure

.(you can use {{EX:CFLAGS}} to specify compiler flags)

* Preprocessor Flags

.You may specify additional preprocessor flags by setting
{{EX:CPPFLAGS}}.  For example, if you would like to use headers
installed in {{F:/usr/local/include}}, use:

E:	% [env] CPPFLAGS="-I/usr/local/include" ./configure

.You can also use {{EX:CPPFLAGS}} to specify preprocessor macros.

E:	% [env] CPPFLAGS="-D__SPECIAL_FLAG__" ./configure

* Linker Flags

.You may specify additional linker flags by setting {{EX:LDFLAGS}}.
For example, if you would like to use libraries installed
in {{F:/usr/local/lib}}, use:

E:	% [env] LDFLAGS="-L/usr/local/lib" ./configure

.You can also use CPPFLAGS to specify linker flags:

E:	% [env] LDFLAGS="-Bstatic" ./configure

* Path

.You may alter your path to affect configure ability to
find (or not find) commands.  For example, to have configure
additionally look in {{F:/usr/css/bin}} for commands, use:

E:	% [env] PATH="/usr/css/bin:$PATH" ./configure
	
* Using locally installed software

.To use software under installed under {{F:/usr/local}}.

E:	[env] \
E:		CPPFLAGS="-I/usr/local/include" \
E:		LDFLAGS="-L/usr/local/lib" \
E:		./configure

Note: You may have add additional flags if your system
supports shared libraries.
