28 This script configures notmuch to build on your system.
30 It verifies that dependencies are available, determines flags needed
31 to compile and link against various required libraries, and identifies
32 whether various system functions can be used or if locally-provided
33 replacements will be built instead.
35 Finally, it allows you to control various aspects of the build and
38 First, some common variables can specified via environment variables:
40 CC The C compiler to use
41 CFLAGS Flags to pass to the C compiler
42 CXX The C++ compiler to use
43 CXXFLAGS Flags to pass to the C compiler
44 LDFLAGS Flags to pass when linking
46 Each of these values can further be controlled by specifying them
47 later on the "make" command line.
49 Other environment variables can be used to control configure itself,
50 (and for which there is no equivalent build-time control):
52 XAPIAN_CONFIG The program to use to determine flags for
53 compiling and linking against the Xapian
54 library. [$XAPIAN_CONFIG]
56 Additionally, various options can be specified on the configure
59 --prefix=PREFIX Install files in PREFIX [$PREFIX]
61 By default, "make install" will install the resulting program to
62 $PREFIX/bin, documentation to $PREFIX/man, etc. You can
63 specify an installation prefix other than $PREFIX using
64 --prefix, for instance:
66 ./configure --prefix=\$HOME
68 Fine tuning of some installation directories is available:
70 --libdir=DIR Install libraries to DIR [PREFIX/lib]
71 --includedir=DIR Install header files to DIR [PREFIX/include]
72 --mandir=DIR Install man pages to DIR [PREFIX/share/man]
73 --sysconfdir=DIR Read-only single-machine data [PREFIX/etc]
74 --emacslispdir=DIR Emacs code [PREFIX/share/emacs/site-lisp]
76 Additional options are accepted for compatibility with other
77 configure-script calling conventions, but don't do anything yet:
79 --build=<cpu>-<vendor>-<os> Currently ignored
80 --infodir=DIR Currently ignored
81 --localstatedir=DIR Currently ignored

142 Welcome to Notmuch, a system for indexing, searching and tagging your email.
144 We hope that the process of building and installing notmuch is quick
145 and smooth so that you can soon be reading and processing your email
146 more efficiently than ever.
148 If anything goes wrong in the configure process, you can override any
149 decisions it makes by manually editing the Makefile.config file that
150 it creates. Also please do as much as you can to figure out what could
151 be different on your machine compared to those of the notmuch
152 developers. Then, please email those details to the Notmuch list
153 (notmuch@notmuchmail.org) so that we can hopefully make future
154 versions of notmuch easier for you to use.
156 We'll now investigate your system to verify that all required
157 dependencies are available:

169 printf "Checking for Xapian development files... "
171 for xapian_config in ${XAPIAN_CONFIG}; do
172 if ${xapian_config} --version > /dev/null 2>&1; then
175 xapian_cxxflags=$(${xapian_config} --cxxflags)
176 xapian_ldflags=$(${xapian_config} --libs)
180 if [ ${have_xapian} = "0" ]; then
182 errors=$((errors + 1))
185 printf "Checking for GMime 2.4 development files... "
186 if pkg-config --modversion gmime-2.4 > /dev/null 2>&1; then
189 gmime_cflags=$(pkg-config --cflags gmime-2.4)
190 gmime_ldflags=$(pkg-config --libs gmime-2.4)
194 errors=$((errors + 1))
197 printf "Checking for talloc development files... "
198 if pkg-config --modversion talloc > /dev/null 2>&1; then
201 talloc_cflags=$(pkg-config --cflags talloc)
202 talloc_ldflags=$(pkg-config --libs talloc)
207 errors=$((errors + 1))
210 printf "Checking for valgrind development files... "
211 if pkg-config --modversion valgrind > /dev/null 2>&1; then

220 if [ -z "${EMACSLISPDIR}" ]; then

222 EMACSLISPDIR=$(pkg-config emacs --variable sitepkglispdir)
224 EMACSLISPDIR='$(prefix)/share/emacs/site-lisp'
228 printf "Checking if emacs is available... "
229 if emacs --quick --batch > /dev/null 2>&1; then
233 printf "No (so will not byte-compile emacs code)\n"
237 if [ $errors -gt 0 ]; then
240 *** Error: The dependencies of notmuch could not be satisfied. You will
241 need to install the following packages before being able to compile
245 if [ $have_xapian -eq 0 ]; then
246 echo " Xapian library (including development files such as headers)"

259 With any luck, you're using a modern, package-based operating system
260 that has all of these packages available in the distribution. In that
261 case a simple command will install everything you need. For example:
263 On Debian and similar systems:
265 sudo apt-get install libxapian-dev libgmime-2.4-dev libtalloc-dev
267 Or on Fedora and similar systems:
269 sudo yum install xapian-core-devel gmime-devel libtalloc-devel
271 On other systems, similar commands can be used, but the details of the
272 package names may be different.
275 if [ $have_pkg_config -eq 0 ]; then
277 Note: the pkg-config program is not available. This configure script
278 uses pkg-config to find the compilation flags required to link against
279 the various libraries needed by notmuch. It's possible you simply need
280 to install pkg-config with a command such as:
282 sudo apt-get install pkg-config
284 sudo yum install pkgconfig
286 But if pkg-config is not available for your system, then you will need
287 to modify the configure script to manually set the cflags and ldflags
288 variables to the correct values to link against each library in each
289 case that pkg-config could not be used to determine those values.
294 When you have installed the necessary dependencies, you can run
295 configure again to ensure the packages can be found, or simply run
296 "make" to compile notmuch.
