Previously, the makefile created dependency files in a separate, first pass. In particular, include-ing the dependency files would cause make to attempt to rebuild those files using the dependency-generation rules in the makefile. Unfortunately, this approach required obtuse rules and silently delayed the start of the build process (by quite a bit on a clean tree without any dependency files). Worse, this required the dependency files to themselves depend on all of the headers the source file depended on, which meant that, if a header file was removed, the depedency file could not be updated because of a missing dependency (!), which would cause make to silently fail. This patch eliminates the dependency generation rules and instead generates dependency files as a side-effect of the regular build rule. On the first build, we don't need to know the dependencies beforehand; the object file doesn't exist, so it will be built anyway. On subsequent builds, if a header file is updated, the dependency rules generated by the previous build will force a rebuild. If a source file is updated, the dependency rules may be stale, but it doesn't matter because the updated source file will force a rebuild. In the final case above, the stale dependency rules may refer to a header file that no longer exists but is also no longer needed. In order to prevent this from breaking the build, we also pass gcc the -MP option, which generates phony targets for every depended-on header file, so make won't complain if it can't find them during a later build. |

Notmuch - thread-based email index, search and tagging. Notmuch is a system for indexing, searching, reading, and tagging large collections of email messages in maildir or mh format. It uses the Xapian library to provide fast, full-text search with a convenient search syntax. Notmuch is free software, released under the GNU General Public License version 3 (or later). Building notmuch ---------------- See the INSTALL file for notes on compiling and installing notmuch. Running notmuch --------------- After installing notmuch, start by running "notmuch setup" which will interactively prompt for configuration information such as your name, email address, and the directory which contains your mail archive to be indexed. You can change any answers later by running "notmuch setup" again or by editing the .notmuch-config file in your home directory. With notmuch configured you should next run "notmuch new" which will index all of your existing mail. This can take a long time, (several hours) if you have a lot of email, (hundreds of thousands of files). When new mail is delivered to your mail archive in the future, you will want to run "notmuch new" again. These runs will be much faster as they will only index new messages. Finally, you can prove to yourself that things are working by running some command-line searches such as "notmuch search from:someone@example.com" or "notmuch search subject:topic". See "notmuch help search-terms" for more details on the available search syntax. The command-line search output is not expected to be particularly friendly for day-to-day usage. Instead, it is expected that you will use an email interface that builds on the notmuch command-line tool or the libnotmuch library. Notmuch installs a full-featured email interface for use within emacs. To use this, first add the following line to your .emacs file: (require 'notmuch) Then, either run "emacs -f notmuch" or execute the command "M-x notmuch" from within a running emacs. If you're interested in a non-emacs-based interface to notmuch, then please join the notmuch community. Various other interfaces are already in progress, (an interface within vim, a curses interface, graphical interfaces based on evolution, and various web-based interfaces). The authors of these interfaces would love further testing or contribution. See contact information below.
