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]

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]
	--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 [SYSCONFDIR/bash_completion.d]
	--zshcompletiondir=DIR	Zsh completions files [PREFIX/share/zsh/functions/Completion/Unix]

Some specific library versions can be specified (auto-detected otherwise):

        --with-gmime-version=VERS       Specify GMIME version (2.4 or 2.6)

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

	--without-emacs			Do not install lisp file
	--without-bash-completion	Do not install bash completions files
	--without-zsh-completion	Do not install zsh completions files

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
	--infodir=DIR			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:

With any luck, you're using a modern, package-based operating system
that has all of these packages available in the distribution. In that
case a simple command will install everything you need. For example:

On Debian and similar systems:

	sudo apt-get install libxapian-dev libgmime-2.6-dev libtalloc-dev

Or on Fedora and similar systems:

	sudo yum install xapian-core-devel gmime-devel libtalloc-devel

On other systems, similar commands can be used, but the details of the
package names may be different.

Note: the pkg-config program is not available. This configure script
uses pkg-config to find the compilation flags required to link against
the various libraries needed by notmuch. It's possible you simply need
to install pkg-config with a command such as:

	sudo apt-get install pkg-config
Or:
	sudo yum install pkgconfig

But if pkg-config is not available for your system, then you will need
to modify the configure script to manually set the cflags and ldflags
variables to the correct values to link against each library in each
case that pkg-config could not be used to determine those values.
