If you want to build binaries for more than one platform from a single
source tree, skip ahead to the "Building LDAP For More Than One Platform"
13
section near the end of this file.

If you simply want to build LDAP for a single machine platform, follow
these steps:

 1. untar the distribution and cd to the top:

20
	% tar xfz openldap-VERSION.tgz
21
	% cd ldap

    If you are reading this file, you probably have already done this!

 3. edit the file include/ldapconfig.h.edit to configure
    the software for your site (the files are well-commented):

    do this (depending on where you are installing things):

	% su
	# make install

    That's it!  See the man pages for the individual clients for information
    on configuring and using them.  Eventually you will probably want to
    edit the configuration files used by the various clients (installed in
    the LDAP etc directory).  The files are:

	ldapfilter.conf      - search filter configuration
	ldapfriendly         - mapping of X.500 names to human-friendly names
	ldapsearchprefs.conf - search object definitions
	ldaptemplates.conf   - display template definitions

    There are section 5 man pages for all of these files.


Building LDAP For More Than One Platform

It is now possible to build LDAP for more than one platform from the same

source tree.  This is accomplished by using make(1) VPATH support.  If
your make(1) program is old and doesn't have VPATH support, install GNU
Make.

Follow these steps for each different platform:

 1.	Create a directory for the platform object files.

 4. Continue as above (starting at step 6).

	Note: make depend in VPATH environment is not yet supported.

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.

	CPPFLAGS	CPP Flags		(-I/path/include -Ddef)
	LDFLAGS		LDFLAGS			(-L/path/lib -llib)
	PATH		command path	/usr/local/bin:/usr/bin:/bin

* Including alternative compilers
	Use the CC environment variable to tell configure to
	use a specific compiler.  For example, to use ecgs
	instead of the compiler configure choose, use:

	[env] CC=ecgs ./configure 

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

	[env] CC="gcc -ansi -predantic" ./configure

	(you can use CFLAGS to specify compiler flags)

* Preprocessor Flags
	You may specify additional preprocessor flags by setting
	CPPFLAGS.  For example, if you would like to use headers
	installed in /usr/local/include, use:

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

	You can also use CPPFLAGS to specify preprocessor macros.

	[env] CPPFLAGS="-D__SPECIAL_FLAG__" ./configure

* Linker Flags
	You may specify additional linker flags by setting LDFLAGS.
	For example, if you would like to use libraries installed
	in /usr/local/lib, use:

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

	You can also use CPPFLAGS to specify linker flags:

	[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 /usr/css/bin for commands, use:

	[env] PATH="/usr/css/bin:$PATH" ./configure
