- Capitalize section titles correctly - Rename "Building on Windows" to "Building on non-Unix systems" and tweak the text accordingly. - Remove the "Installing Prebuilt Binaries" section. This info is better in the web instead, as it may change. - Mention that Sphinx 1.0 or newer is required.

Compiling and Installing Jansson
|
|
================================
|
|
|
|
The Jansson source is available at
|
|
http://www.digip.org/jansson/releases/.
|
|
|
|
Unix-like systems
|
|
-----------------
|
|
|
|
Unpack the source tarball and change to the source directory:
|
|
|
|
.. parsed-literal::
|
|
|
|
bunzip2 -c jansson-|release|.tar.bz2 | tar xf -
|
|
cd jansson-|release|
|
|
|
|
The source uses GNU Autotools (autoconf_, automake_, libtool_), so
|
|
compiling and installing is extremely simple::
|
|
|
|
./configure
|
|
make
|
|
make check
|
|
make install
|
|
|
|
To change the destination directory (``/usr/local`` by default), use
|
|
the ``--prefix=DIR`` argument to ``./configure``. See ``./configure
|
|
--help`` for the list of all possible installation options. (There are
|
|
no options to customize the resulting Jansson binary.)
|
|
|
|
The command ``make check`` runs the test suite distributed with
|
|
Jansson. This step is not strictly necessary, but it may find possible
|
|
problems that Jansson has on your platform. If any problems are found,
|
|
please report them.
|
|
|
|
If you obtained the source from a Git repository (or any other source
|
|
control system), there's no ``./configure`` script as it's not kept in
|
|
version control. To create the script, the build system needs to be
|
|
bootstrapped. There are many ways to do this, but the easiest one is
|
|
to use ``autoreconf``::
|
|
|
|
autoreconf -vi
|
|
|
|
This command creates the ``./configure`` script, which can then be
|
|
used as described above.
|
|
|
|
.. _autoconf: http://www.gnu.org/software/autoconf/
|
|
.. _automake: http://www.gnu.org/software/automake/
|
|
.. _libtool: http://www.gnu.org/software/libtool/
|
|
|
|
|
|
Other Systems
|
|
-------------
|
|
|
|
On Windows and other non Unix-like systems, you may be unable to run
|
|
the ``./configure`` script. In this case, follow these steps. All the
|
|
files mentioned can be found in the ``src/`` directory.
|
|
|
|
1. Create ``jansson_config.h``. This file has some platform-specific
|
|
parameters that are normally filled in by the ``./configure``
|
|
script:
|
|
|
|
- On Windows, rename ``jansson_config.h.win32`` to ``jansson_config.h``.
|
|
|
|
- On other systems, edit ``jansson_config.h.in``, replacing all
|
|
``@variable@`` placeholders, and rename the file to
|
|
``jansson_config.h``.
|
|
|
|
2. Make ``jansson.h`` and ``jansson_config.h`` available to the
|
|
compiler, so that they can be found when compiling programs that
|
|
use Jansson.
|
|
|
|
3. Compile all the ``.c`` files (in the ``src/`` directory) into a
|
|
library file. Make the library available to the compiler, as in
|
|
step 2.
|
|
|
|
|
|
Building the Documentation
|
|
--------------------------
|
|
|
|
(This subsection describes how to build the HTML documentation you are
|
|
currently reading, so it can be safely skipped.)
|
|
|
|
Documentation is in the ``doc/`` subdirectory. It's written in
|
|
reStructuredText_ with Sphinx_ annotations. To generate the HTML
|
|
documentation, invoke::
|
|
|
|
make html
|
|
|
|
and point your browser to ``doc/_build/html/index.html``. Sphinx_ 1.0
|
|
or newer is required to generate the documentation.

|
Compiling Programs that Use Jansson
|
|
===================================
|
|
|
|
Jansson involves one C header file, :file:`jansson.h`, so it's enough
|
|
to put the line
|
|
|
|
::
|
|
|
|
#include <jansson.h>
|
|
|
|
in the beginning of every source file that uses Jansson.
|
|
|
|
There's also just one library to link with, ``libjansson``. Compile and
|
|
link the program as follows::
|
|
|
|
cc -o prog prog.c -ljansson
|
|
|
|
Starting from version 1.2, there's also support for pkg-config_::
|
|
|
|
cc -o prog prog.c `pkg-config --cflags --libs jansson`
|
|
|
|
.. _pkg-config: http://pkg-config.freedesktop.org/
