Add checks to "configure" to see whether _POSIX_PTHREAD_SEMANTICS needs
to be defined to get the right number of arguments in the prototypes for
getpwuid_r(). Solaris' default implementation conforms to POSIX.1c
Draft 6, rather than the final POSIX.1c spec. The standards-compliant
version can be used by defining _POSIX_PTHREAD_SEMANTICS.
This change also adds the file "compat/check_getpwuid.c", which
configure uses to perform its check, and modifies compat/compat.h to
define _POSIX_PTHREAD_SEMANTICS if configure detected it was needed.

It turns out that if people really use configure in autotools style and pass
libdir containing '${prefix}/foo' then the ldconfig previously failed.
This uses sed for portability (versus bash parameter expansion with
substitution) and hopefully a bit more robustness than blindly
parameter expanding the string.
-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.

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

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.
I'm not sure that this option would actually be useful for anything,
but debhelper at least expects our configure script to support it. So
we'll accept it and ignore it.
It makes sense to me to have the little tests for functionality right
next to the comptability implementations of that same functionality.
But also, this means I can now tab-complete ./configure from the three
initial characters (rather than the seven required previously).
Instead, simply byte-compile the emacs source files as part of "make"
and install them as part of "make install". The byte compilation is
made conditional on the configure script finding the emacs binary.
That way, "make; make install" will still work for someone that doesn't
have emacs installed, (which was the only reason we had made a separate
"make install-emacs" target in the first place).
With the original quiet function, there's an actual purpose (hiding
excessively long compiler command lines so that warnings and errors
from the compiler can be seen).
But with things like quiet_symlink there's nothing quieter. In fact
"SYMLINK" is longer than "ln -sf". So all this is doing is hiding the
actual command from the user for no real benefit.
The only actual reason we implemented the quiet_* functions was to be
able to neatly right-align the command name and left-align the arguments.
Let's give up on that, and just left-align everything, simplifying the
Makefiles considerably. Now, the only instances of a captialized command
name in the output is if there's some actually shortening of the command
itself.
One of the supproted mechanisms we offer for configuration is
manually editing the Makefile.config file after it is generated
by the configure script. In this case it would be nice to be able
to change prefix only once, so allow that.
There's not any special configure logic for determining these variable
values, but if we did add some in the future, then these will now be
in the right place for that.
Additionally, this now makes Makefile.local the single place for the
user to look for manually tweaking a variable assignment, (say, for a
compiler that can't accept a particular warning argument).
With this change, there should rarely be any need for a user to poke
into any Makefile.local file.
If an explicit --libdir is passed, then that is used directly. Otherwise
libdir is chosen as the value of $PREFIX/lib, (whether or not prefix was
passed explicitly or set by default).
Add an install target that uses desktop-file-install to install the

The in-development version of Xapian provides a config program named
xapian-config-1.1 while the released version provides a program named
xapian-config instead. By default, we now try each of these in turn,
and we also allow the user to set a XAPIAN_CONFIG environment variable
to explicitly specify a particular program.
These variables can now be set via configure time via environment
variables like so:
CFLAGS=-g ./configure
and subsequent builds will remember these values. The values can
still be overridden at compile time by passing make variables:
make CFLAGS=-O2
The CXXFLAGS variable is optional. If unset at either configure
time or at compile time, it will inherit its value from the
CFLAGS variable. (Though if explicitly set at configure time
it must be explicitly overriden at compile time---just overriding
CFLAGS will not override CXXFLAGS as well.)
The only reason I ever call "make V=1" myself, (other than when
debugging the compiler command-line for some reason), is to ensure
whether my CFLAGS, (like "-g -O0" or "-O2"), are actually making it to
the command-line.
But these are hard to find in the V=1 output, and really, we should
just print these even in the quiet case. So do that.

The environment variables CC and CXX can be set at configure time to
specify what compiler to use. This compiler will be used for any
configure-time compilation, and will also be recorded in
Makefile.config to be used during the actual build.
The compiler to be used can still be overridden at build time by using
a make variable such as:
make CC=gcc
Each dependency now gets its own variable in the resulting
Makefile.config to make it much easier to debug where the various
flags came from in the case of any problems.
It's probably a bit more work to use this configure script without
pkg-config, but it's at least possible, (and we could make it even
easier if this becomes an important use case).
Previously, we were resolving these within the Makefile. This had
the problem that if pkg-config was not present, the Makefile would
still invoke it resulting in ugly errors before the configure script
was even run, (which would finally present a kind error message about
pkg-config not being present).
This keeps configure-related clutter out of the main directory, and
also gives a more direct correlation between the name of the test and
the feature being tested for.
We're now using printf to print what we're checking before we check. We're
also making variables such as HAVE_GETLINE available to both make and to
the C pre-processor.
With this, the local getline implementation is now only compiled if not
available on the system.
Add a simple test to the configure script to detect getline. It's not
important that the test run, just that it compiles and links without
any errors.

We were missing an "override" directive in the assignment of CFLAGS
within Makefile.config so it was actually having no effect. Then, we
were also failing to get the proper include path for valgrind.h so
it wouldn't have worked even it were having effect. Fix both problems.
We had avoided using "echo -n" originally for portability concerns,
and instead just printed the same string in both conditions, (and
also printed the string late if any check took long). The word is
that printf is quite portable, so we use that instead.
It was problematic to have this in "make install" since it would
unconditionally try to install to /etc, (even if a non-privileged user
was attempting an install to a prefix in the user's home directory,
for example).
I felt sorry for Carl trying to step through an exception from xapian
and suffering from the SIGALARMs..
We can detect if the user launched notmuch under a debugger by either
checking our cmdline for the presence of the gdb string or querying if
valgrind is controlling our process. For the latter we need to add a
compile time check for the valgrind development library, and so add the
initial support to build Makefile.config from configure.

This is *not* based on autoconf. In fact, this doesn't actually

The only thing that this configure script does is to check for the

the user if they are not all available.
