-Wswitch-enum is a bit awkward if a switch statement is intended to
handle just some of the named codes of an enumeration especially, and
leave the rest to the default label.
We already have -Wall, which enables -Wswitch by default, and per GCC
documentation, "The only difference between -Wswitch and this option
[-Wswitch-enum] is that this option gives a warning about an omitted
enumeration code even if there is a default label."
Drop -Wswitch-enum to not force listing all named codes of
enumerations in switch statements that have a default label.
OpenBSD's build flags are identical to FreeBSD, except that libraries
need to be explicitly linked against libc. No code changes are
necessary.

'configure' script uses parameter substring extensively. It is Posix shell
feature. Original Bourne shell does not have such features. Some systems
still ships such shells as /bin/sh (for compatibility reasons -- shell
scripts written on those platforms are expected to work on 1990's systems).
Just testing whether parameter substring processing works will make the
shell exit due to syntax error if it is not compatible. Therefore the test
is executed in a subshell -- subshell exits with nonzero value when the
operation in question fails.
As 'if ! ...' does not work in Bourne shell, Short-circuiting construct
'||' is used to print information message and exit when expected.
Without proper quoting the DEFAULT_IFS was getting set incorrectly,
which was causing problems with the storage of some variables later in
the script. Quoting fixes the problem.
Since GMime 2.6 is now the stable version upstream, and probably the
most tested by notmuch developers, it makes sense to suggest that to
users to install.
Currently whenever message about missing GMime, Glib or talloc is
printed the message is 2 lines, component info and its http location
in next line. In the future the amount of lines will vary. To ease
reading in these cases newline is added after each message.
This allows for testing against both versions of gmime on a single
machine, without having to mess with pkg-config paths.
This is rework of Tom Prince's patch submitted in
id:"1331402091-15663-1-git-send-email-tom.prince@ualberta.net"
In the future, IFS value needs to be changed in a few places
in configure -- and then restored. Store the original value
to $DEFAULT_IFS for easy restoration.
Formerly the code assumed the arguments to be triples and threw an
error if this was not the case. But those arguments are only there for
compatibility with autotools and are not used within the build system,
so just dropping the code parsing these values makes the build system
more robust.

gmime-2.6 had a bug [1] which made it impossible to tell why a signature
verification failed when the signer key was unavailable (empty "sigstatus" field
in the JSON output). Since 00b5623d the corresponding test is marked as broken
when using gmime-2.6 (2.4 is fine).
This bug has been fixed in gmime 2.6.5, which is now the minimal gmime-2.6
version required for building notmuch (gmime-2.4 is still available). As a
consequence the version check in test/crypto can be removed.
[Added by db]
Although less unambigously a bug, Gmime 2.6 prior to 2.6.7 also was
more strict about parsing, and rejected messages with initial "From "
headers. This restriction is relaxed in [2]. For reasons explained in [3],
we want to keep this more relaxed parsing for now.

Previously, the configure script would appear to detect gmime-2.6 if
present. However, the binaries would end up being compiled against
gmime-2.4. The addition of a break fixes things so that now gmime-2.6
will be used if available, falling back to gmime-2.4.
As of commit b3caef1f, we're using g_array_unref() in 'lib/query.cc',
which was only introduced in glib 2.22, so update the dependency.

Various typo fixes in comments within the Makefile and other build scripts.

Edited-by: Carl Worth <cworth@cworth.org> Restricted to just build files.
Ever since commit b4b5e9ce4d the
detection of libdir in the ldconfig configuration has been broken,
resulting in RPATH being set when not needed and not wanted.
The cause was a change from an IFS setting of:
IFS="$(printf '\n\t')"
to a new setting of:
IFS="$(printf '\n')"
That looks desirable since we want to split the output of ldconfig
based on newlines, (and not split on any filename that might have an
embedded tab in it). The subtle bug in the above is that the shell
trims any trailing newlines when performing command substitution so
the final statement above was equivalent to:
IFS=''
which prevented any splitting of the ldconfig output at all.
Fix this by avoiding command substitution and just using a literal
newline in the source file for setting this variable.
This supports the case of a user running "configure --prefix=/foo" then later
updating the soruce (including the configure script) and re-running make.
In this case, the make invocation will re-run configure. Before this change,
this run of configure would lose the user's carefully chosen prefix. This
is now fixed so that configrue is re-run with the user's options.
Such as:
mkdir build
cd build
../configure
make
This is implemented by having the configure script set a srcdir
variable in Makefile.config, and then sprinkling $(srcdir) into
various make rules. We also use vpath directives to convince GNU make
to find the source files from the original source directory.
This was originally intended to help support filenames with spaces in
them, but this actually breaks things when someone sets a command with
a space in it, (such as CC="ccache cc").
Instead, we now only set a custom IFS when acting on the
newline-separated list of files from /sbin/ldconfig.
add --bashcompletiondir and --zshcompletiondir (like --emacslispdir) to choose
installation dir for bash/zsh completion files
Make some features optional:
--without-emacs / --with-emacs=no do not install lisp file
--without-bash-completion / --with-bash-completion=no do not install bash
files
--without-zsh-completion / --with-zsh-completion=no do not install zsh files
By default, everything is enabled. You can reenable something with
--with-feature=yes
With --modversion we were asking for output that we were just throwing
away anyway. The --exists option does just what we want, (no output
and communivating only via return value).
Also, --exists allows for testing versions of the package as well.
This fits with our general build philosophy of checking at configure
time for desired support, (rather than putting platform-specific
conditionals into our Makefiles).
Previously, we preferred a value of "xapian-config-1.1" first. This
was convenient for compiling against Xapian 1.1 while Xapian 1.2 was
unreleased. But now that Xapian 1.2 is realease, and since it ships a
xapian-config, the xapian-config-1.1 value can mask the newer library.
Instead of trying to track the latest xapian-config-1.x in our
configure script let's simply expect the user to set
XAPIAN_CONFIG=xapian-config-1.x in order to compile against an
unreleased Xapian.
Various users were confused as to why they couldn't run notmuch
immediately after "make install", (with linker errors saying that
libnotmuch.so could not be found). The errors came from two different
causes:
1. The user had installed to a system library directory, but had not
yet run ldconfig.
2. The user had installed to some non-system directory, and had not
set the LD_LIBRARY_PATH variable.
With this change we fix both problems (on Linux) without the user
having to do anything additional. We first use ldconfig to find the
system library directories. If the user is installing to one of these,
then we run ldconfig as part of "make install".
For case (2) we use the -rpath and --enable-new-dtags linker options
to install a DT_RUNPATH entry in the binary. This entry tells the
dynamic linker where to find libnotmuch. Without the
--enable-new-dtags option only a DT_RPATH option would be installed,
(which has the drawback of not allowing any override with the
LD_LIBRARY_PATH variable).
Distributions (such as Debian and Fedora) don't want to see binaries
packaged with a DT_RPATH or DT_RUNPATH entry. This should be avoided
automatically as long as the packages install to standard locations,
(such as /usr/lib).
The idea here is to more easily support filenames with spaces in them
in various loops. We're about to add a loop over the paths configured
by the dynamic linker. Hopefully, they wouldn't contain spaces, but
one never knows so we might as well be prepared.
The configure usage string documents that it respects LDFLAGS, but
currently it doesn't do anything with the configure-time LDFLAGS
value.

[Tomas and Nelson sent almost identical patches which I've merged
together here.]
This way when GMime 2.8 comes out we can simply add it to the list
rather than adding an additional block of conditional code for it.
Also GMime 2.6 is now preferred over GMime 2.4.
Before and after the assignment operator, no spaces are allowed.
I don't know if there are any /bin/sh which allow spaces, but at least
in bash, csh and zsh, the former code was no valid assigment.
Apparently the OS X linker can't resolve symbols when linking a
program (notmuch) against a library (libnotmuch) when the library
depends on another library (libgmime) that the program doesn't depend
on directly.
For this case, we need to link the program directly against both
libraries, but we don't want to do this on Linux, where the linker can
do this on its own and the explicit, unneeded link would cause
problems.
This patch adds a configure check for OS X (actually Darwin),
and sets up the Makefiles to build a proper shared library on
that platform.

And just make the Debian packaging request site-lisp/notmuch like it
wants. Otherwise, the installed files won't appear on the load-path
so won't be found by emacs.
Which means that the bash completion script will now install
to ${prefix}/etc by default (unless configured with --syconfdir=/etc)
which is probably the right thing to do.
