59 Usage: ./configure [options]...
61 This script configures notmuch to build on your system.
63 It verifies that dependencies are available, determines flags needed
64 to compile and link against various required libraries, and identifies
65 whether various system functions can be used or if locally-provided
66 replacements will be built instead.
68 Finally, it allows you to control various aspects of the build and
71 First, some common variables can specified via environment variables:
73 CC The C compiler to use
74 CFLAGS Flags to pass to the C compiler
75 CXX The C++ compiler to use
76 CXXFLAGS Flags to pass to the C compiler
77 LDFLAGS Flags to pass when linking
79 Each of these values can further be controlled by specifying them
80 later on the "make" command line.
82 Other environment variables can be used to control configure itself,
83 (and for which there is no equivalent build-time control):
85 XAPIAN_CONFIG The program to use to determine flags for
86 compiling and linking against the Xapian
87 library. [$XAPIAN_CONFIG]
89 Additionally, various options can be specified on the configure
92 --prefix=PREFIX Install files in PREFIX [$PREFIX]
94 By default, "make install" will install the resulting program to
95 $PREFIX/bin, documentation to $PREFIX/man, etc. You can
96 specify an installation prefix other than $PREFIX using
97 --prefix, for instance:
99 ./configure --prefix=\$HOME
101 Fine tuning of some installation directories is available:
103 --libdir=DIR Install libraries to DIR [PREFIX/lib]
104 --includedir=DIR Install header files to DIR [PREFIX/include]
105 --mandir=DIR Install man pages to DIR [PREFIX/share/man]
106 --sysconfdir=DIR Read-only single-machine data [PREFIX/etc]
107 --emacslispdir=DIR Emacs code [PREFIX/share/emacs/site-lisp]
108 --emacsetcdir=DIR Emacs miscellaneous files [PREFIX/share/emacs/site-lisp]
109 --bashcompletiondir=DIR Bash completions files [SYSCONFDIR/bash_completion.d]
110 --zshcompletiondir=DIR Zsh completions files [PREFIX/share/zsh/functions/Completion/Unix]
112 Some features can be disabled (--with-feature=no is equivalent to
115 --without-emacs Do not install lisp file
116 --without-bash-completion Do not install bash completions files
117 --without-zsh-completion Do not install zsh completions files

219 Welcome to Notmuch, a system for indexing, searching and tagging your email.
221 We hope that the process of building and installing notmuch is quick
222 and smooth so that you can soon be reading and processing your email
223 more efficiently than ever.
225 If anything goes wrong in the configure process, you can override any
226 decisions it makes by manually editing the Makefile.config file that
227 it creates. Also please do as much as you can to figure out what could
228 be different on your machine compared to those of the notmuch
229 developers. Then, please email those details to the Notmuch list
230 (notmuch@notmuchmail.org) so that we can hopefully make future
231 versions of notmuch easier for you to use.
233 We'll now investigate your system to verify that all required
234 dependencies are available:

420 With any luck, you're using a modern, package-based operating system
421 that has all of these packages available in the distribution. In that
422 case a simple command will install everything you need. For example:
424 On Debian and similar systems:
426 sudo apt-get install libxapian-dev libgmime-2.4-dev libtalloc-dev
428 Or on Fedora and similar systems:
430 sudo yum install xapian-core-devel gmime-devel libtalloc-devel
432 On other systems, similar commands can be used, but the details of the
433 package names may be different.
436 if [ $have_pkg_config -eq 0 ]; then
438 Note: the pkg-config program is not available. This configure script
439 uses pkg-config to find the compilation flags required to link against
440 the various libraries needed by notmuch. It's possible you simply need
441 to install pkg-config with a command such as:
443 sudo apt-get install pkg-config
445 sudo yum install pkgconfig
447 But if pkg-config is not available for your system, then you will need
448 to modify the configure script to manually set the cflags and ldflags
449 variables to the correct values to link against each library in each
450 case that pkg-config could not be used to determine those values.
455 When you have installed the necessary dependencies, you can run
456 configure again to ensure the packages can be found, or simply run
457 "make" to compile notmuch.
