79 Usage: ./configure [options]...
81 This script configures notmuch to build on your system.
83 It verifies that dependencies are available, determines flags needed
84 to compile and link against various required libraries, and identifies
85 whether various system functions can be used or if locally-provided
86 replacements will be built instead.
88 Finally, it allows you to control various aspects of the build and
91 First, some common variables can specified via environment variables:
93 CC The C compiler to use
94 CFLAGS Flags to pass to the C compiler
95 CPPFLAGS Flags to pass to the C preprocessor
96 CXX The C++ compiler to use
97 CXXFLAGS Flags to pass to the C compiler
98 LDFLAGS Flags to pass when linking
100 Each of these values can further be controlled by specifying them
101 later on the "make" command line.
103 Other environment variables can be used to control configure itself,
104 (and for which there is no equivalent build-time control):
106 XAPIAN_CONFIG The program to use to determine flags for
107 compiling and linking against the Xapian
108 library. [$XAPIAN_CONFIG]
110 Additionally, various options can be specified on the configure
113 --prefix=PREFIX Install files in PREFIX [$PREFIX]
115 By default, "make install" will install the resulting program to
116 $PREFIX/bin, documentation to $PREFIX/man, etc. You can
117 specify an installation prefix other than $PREFIX using
118 --prefix, for instance:
120 ./configure --prefix=\$HOME
122 Fine tuning of some installation directories is available:
124 --libdir=DIR Install libraries to DIR [PREFIX/lib]
125 --includedir=DIR Install header files to DIR [PREFIX/include]
126 --mandir=DIR Install man pages to DIR [PREFIX/share/man]
127 --sysconfdir=DIR Read-only single-machine data [PREFIX/etc]
128 --emacslispdir=DIR Emacs code [PREFIX/share/emacs/site-lisp]
129 --emacsetcdir=DIR Emacs miscellaneous files [PREFIX/share/emacs/site-lisp]
130 --bashcompletiondir=DIR Bash completions files [SYSCONFDIR/bash_completion.d]
131 --zshcompletiondir=DIR Zsh completions files [PREFIX/share/zsh/functions/Completion/Unix]
133 Some specific library versions can be specified (auto-detected otherwise):
135 --with-gmime-version=VERS Specify GMIME version (2.4 or 2.6)
137 Some features can be disabled (--with-feature=no is equivalent to
140 --without-emacs Do not install lisp file
141 --without-bash-completion Do not install bash completions files
142 --without-zsh-completion Do not install zsh completions files

249 Welcome to Notmuch, a system for indexing, searching and tagging your email.
251 We hope that the process of building and installing notmuch is quick
252 and smooth so that you can soon be reading and processing your email
253 more efficiently than ever.
255 If anything goes wrong in the configure process, you can override any
256 decisions it makes by manually editing the Makefile.config file that
257 it creates. Also please do as much as you can to figure out what could
258 be different on your machine compared to those of the notmuch
259 developers. Then, please email those details to the Notmuch list
260 (notmuch@notmuchmail.org) so that we can hopefully make future
261 versions of notmuch easier for you to use.
263 We'll now investigate your system to verify that all required

457 With any luck, you're using a modern, package-based operating system
458 that has all of these packages available in the distribution. In that
459 case a simple command will install everything you need. For example:
461 On Debian and similar systems:
463 sudo apt-get install libxapian-dev libgmime-2.6-dev libtalloc-dev
465 Or on Fedora and similar systems:
467 sudo yum install xapian-core-devel gmime-devel libtalloc-devel
469 On other systems, similar commands can be used, but the details of the
470 package names may be different.
473 if [ $have_pkg_config -eq 0 ]; then
475 Note: the pkg-config program is not available. This configure script
476 uses pkg-config to find the compilation flags required to link against
477 the various libraries needed by notmuch. It's possible you simply need
478 to install pkg-config with a command such as:
480 sudo apt-get install pkg-config
482 sudo yum install pkgconfig
484 But if pkg-config is not available for your system, then you will need
485 to modify the configure script to manually set the cflags and ldflags
486 variables to the correct values to link against each library in each
487 case that pkg-config could not be used to determine those values.
492 When you have installed the necessary dependencies, you can run
493 configure again to ensure the packages can be found, or simply run
494 "make" to compile notmuch.
