The output from make is looking better all the time, (though the columns still aren't lined up).

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
|
|
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 in LIBDIR [PREFIX/lib]

|
|
|

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-2.4-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.
|
|
|
|
EOF
|
|
if [ $have_pkg_config -eq 0 ]; then
|
|
cat <<EOF
|
|
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.
|
|
|
|
EOF
|
|
fi
|
|
cat <<EOF
|

When you have installed the necessary dependencies, you can run

configure again to ensure the packages can be found, or simply run

"make" to compile notmuch.
