Usage: ./configure [options]...

This script configures notmuch to build on your system.

It verifies that dependencies are available, determines flags needed
to compile and link against various required libraries, and identifies
whether various system functions can be used or if locally-provided
replacements will be built instead.

Finally, it allows you to control various aspects of the build and
installation process.

First, some common variables can specified via environment variables:

	CC		The C compiler to use
	CFLAGS		Flags to pass to the C compiler
	CPPFLAGS	Flags to pass to the C preprocessor
	CXX		The C++ compiler to use
	CXXFLAGS	Flags to pass to the C compiler
	LDFLAGS		Flags to pass when linking

Each of these values can further be controlled by specifying them
later on the "make" command line.

Other environment variables can be used to control configure itself,
(and for which there is no equivalent build-time control):

	XAPIAN_CONFIG	The program to use to determine flags for
			compiling and linking against the Xapian
			library. [$XAPIAN_CONFIG]
	PYTHON		Name of python command to use in
			configure and the test suite.
	RUBY		Name of ruby command to use in
			configure and the test suite.

Additionally, various options can be specified on the configure
command line.

	--prefix=PREFIX	Install files in PREFIX [$PREFIX]

By default, "make install" will install the resulting program to
$PREFIX/bin, documentation to $PREFIX/man, etc. You can
specify an installation prefix other than $PREFIX using
--prefix, for instance:

	./configure --prefix=\$HOME

Fine tuning of some installation directories is available:

	--libdir=DIR		Install libraries to DIR [PREFIX/lib]
	--includedir=DIR	Install header files to DIR [PREFIX/include]
	--mandir=DIR		Install man pages to DIR [PREFIX/share/man]
	--infodir=DIR		Install man pages to DIR [PREFIX/share/man]
	--sysconfdir=DIR	Read-only single-machine data [PREFIX/etc]
	--emacslispdir=DIR	Emacs code [PREFIX/share/emacs/site-lisp]
	--emacsetcdir=DIR	Emacs miscellaneous files [PREFIX/share/emacs/site-lisp]
	--bashcompletiondir=DIR Bash completions files [PREFIX/share/bash-completion/completions]
	--zshcompletiondir=DIR	Zsh completions files [PREFIX/share/zsh/site-functions]

Some features can be disabled (--with-feature=no is equivalent to
--without-feature) :

	--without-bash-completion	Do not install bash completions files
	--without-docs			Do not install documentation
	--without-api-docs		Do not install API man page
	--without-emacs			Do not install lisp file
	--without-desktop		Do not install desktop file
	--without-ruby			Do not install ruby bindings
	--without-zsh-completion	Do not install zsh completions files
	--without-retry-lock		Do not use blocking xapian opens, even if available

Additional options are accepted for compatibility with other
configure-script calling conventions, but don't do anything yet:

	--build=<cpu>-<vendor>-<os>	Currently ignored
	--host=<cpu>-<vendor>-<os>	Currently ignored
	--datadir=DIR			Currently ignored
	--localstatedir=DIR		Currently ignored
	--libexecdir=DIR		Currently ignored
	--disable-maintainer-mode	Currently ignored
	--disable-dependency-tracking	Currently ignored

Welcome to Notmuch, a system for indexing, searching and tagging your email.

We hope that the process of building and installing notmuch is quick
and smooth so that you can soon be reading and processing your email
more efficiently than ever.

If anything goes wrong in the configure process, you can override any
decisions it makes by manually editing the Makefile.config file that
it creates. Also please do as much as you can to figure out what could
be different on your machine compared to those of the notmuch
developers. Then, please email those details to the Notmuch list
(notmuch@notmuchmail.org) so that we can hopefully make future
versions of notmuch easier for you to use.

We'll now investigate your system to verify that all required
dependencies are available:
