notmuch/Makefile.local, branch 0.5

Makefile: Move the -Wl,-as-needed option earlier in the command line.

2010-11-02T06:24:44Z

This option wasn't having the desired effect, and sure enough, the documentation states that it only affects the linking of libraries that appear after this option on the command line. So put it early for the desired effect.

lib: Add GCC visibility(hidden) pragmas to private header files.

2010-11-02T05:35:48Z

This prevents any of the private functions from being leaked out through the library interface (at least when compiling with a recent-enough gcc to support the visibility pragma).

Makefile: Build library with -Wl,--as-needed

2010-11-01T23:52:22Z

Previously, we were building the final binary with this option, but not the library. The library can benefit from it as well, (as pointed out by Debian's lintian).

configure: Add a check for the -Wl,--as-needed flag.

2010-10-30T20:20:33Z

This fits with our general build philosophy of checking at configure time for desired support, (rather than putting platform-specific conditionals into our Makefiles).

build: only link to what we really use

2010-10-30T20:15:51Z

At least linux has the -Wl,--as-needed option. Signed-off-by: Felipe Contreras

configure: Test for flag to set rpath

2010-10-30T20:15:00Z

This is better than the previous approach which had a hardcoded Linux-specific value in the Makefile.

Makefile: Fix notmuch binary to directly link against Xapian and GMime.

2010-10-29T21:32:48Z

Without this, trying to link with the gold linker would fail, (which meant that notmuch could not be compiled out of the box on recent Fedora, nor even on Debian when the binutils-gold package is installed).

test: Fix test suite to integrate with our non-recursive Makefile system.

2010-09-17T19:16:10Z

This avoids "make test" emitting messages from three (3!) recursive invocations of make. We change the invocations of the tests themselves to occur directly from the shell script rather than having the shell script invoke make again and using wildcards in the Makefile.

make install: Run ldconfig or install a DT_RUNPATH in binary as appropriate.

2010-06-04T23:52:56Z

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).

Makefile: Improve the "what to do now" message from "make install"

2010-06-01T17:51:42Z

This was already telling the user how to run notmuch within emacs, but not how to just run the notmuch command-line interface, (which, as it turns out, is a prerequisite for running the emacs interface anyway). So add a small paragraph here.
