78 Usage: ./configure [options]...
80 This script configures notmuch to build on your system.
82 It verifies that dependencies are available, determines flags needed
83 to compile and link against various required libraries, and identifies
84 whether various system functions can be used or if locally-provided
85 replacements will be built instead.
87 Finally, it allows you to control various aspects of the build and
90 First, some common variables can specified via environment variables:
92 CC The C compiler to use
93 CFLAGS Flags to pass to the C compiler
94 CXX The C++ compiler to use
95 CXXFLAGS Flags to pass to the C compiler
96 LDFLAGS Flags to pass when linking
98 Each of these values can further be controlled by specifying them
99 later on the "make" command line.
101 Other environment variables can be used to control configure itself,
102 (and for which there is no equivalent build-time control):
104 XAPIAN_CONFIG The program to use to determine flags for
105 compiling and linking against the Xapian
106 library. [$XAPIAN_CONFIG]
108 Additionally, various options can be specified on the configure
111 --prefix=PREFIX Install files in PREFIX [$PREFIX]
113 By default, "make install" will install the resulting program to
114 $PREFIX/bin, documentation to $PREFIX/man, etc. You can
115 specify an installation prefix other than $PREFIX using
116 --prefix, for instance:
118 ./configure --prefix=\$HOME
120 Fine tuning of some installation directories is available:
122 --libdir=DIR Install libraries to DIR [PREFIX/lib]
123 --includedir=DIR Install header files to DIR [PREFIX/include]
124 --mandir=DIR Install man pages to DIR [PREFIX/share/man]
125 --sysconfdir=DIR Read-only single-machine data [PREFIX/etc]
126 --emacslispdir=DIR Emacs code [PREFIX/share/emacs/site-lisp]
127 --emacsetcdir=DIR Emacs miscellaneous files [PREFIX/share/emacs/site-lisp]
128 --bashcompletiondir=DIR Bash completions files [SYSCONFDIR/bash_completion.d]
129 --zshcompletiondir=DIR Zsh completions files [PREFIX/share/zsh/functions/Completion/Unix]
131 Some specific library versions can be specified (auto-detected otherwise):
133 --with-gmime-version=VERS Specify GMIME version (2.4 or 2.6)
135 Some features can be disabled (--with-feature=no is equivalent to
138 --without-emacs Do not install lisp file
139 --without-bash-completion Do not install bash completions files
140 --without-zsh-completion Do not install zsh completions files

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

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