Compiling and Installing Jansson
|
|
================================
|
|
|
|
The Jansson source is available at
|
|
http://www.digip.org/jansson/releases/.
|
|
|
|
Unix-like systems (including MinGW)
|
|
-----------------------------------
|
|
|
|
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 configuration options.
|
|
|
|
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 -fi
|
|
|
|
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/
|
|
|
|
|
|
.. _build-cmake:
|
|
|
|
CMake (various platforms, including Windows)
|
|
--------------------------------------------
|
|
|
|
Jansson can be built using CMake_. Create a build directory for an
|
|
out-of-tree build, change to that directory, and run ``cmake`` (or ``ccmake``,
|
|
``cmake-gui``, or similar) to configure the project.
|
|
|
|
See the examples below for more detailed information.
|
|
|
|
.. note:: In the below examples ``..`` is used as an argument for ``cmake``.
|
|
This is simply the path to the jansson project root directory.
|
|
In the example it is assumed you've created a sub-directory ``build``
|
|
and are using that. You could use any path you want.
|
|
|
|
.. _build-cmake-unix:
|
|
|
|
Unix (Make files)
|
|
^^^^^^^^^^^^^^^^^
|
|
Generating make files on unix:
|
|
|
|
.. parsed-literal::
|
|
|
|
bunzip2 -c jansson-|release|.tar.bz2 | tar xf -
|
|
cd jansson-|release|
|
|
|
|
mkdir build
|
|
cd build
|
|
cmake .. # or ccmake .. for a GUI.
|
|
|
|
.. note::
|
|
|
|
If you don't want to build docs or ``Sphinx`` is not installed, you should add ``"-DJANSSON_BUILD_DOCS=OFF"`` in the ``cmake`` command.
|
|
|
|
|
|
Then to build::
|
|
|
|
make
|
|
make check
|
|
make install
|
|
|
|
Windows (Visual Studio)
|
|
^^^^^^^^^^^^^^^^^^^^^^^
|
|
Creating Visual Studio project files from the command line:
|
|
|
|
.. parsed-literal::
|
|
|
|
<unpack>
|
|
cd jansson-|release|
|
|
|
|
md build
|
|
cd build
|
|
cmake -G "Visual Studio 15 2017" ..
|
|
|
|
.. note::
|
|
|
|
You should replace the name of the generator (``-G`` flag) matching
|
|
the Visual Studio version installed on your system. Currently, the
|
|
following versions are supported:
|
|
|
|
- ``Visual Studio 9 2008``
|
|
- ``Visual Studio 10 2010``
|
|
- ``Visual Studio 11 2012``
|
|
- ``Visual Studio 12 2013``
|
|
- ``Visual Studio 14 2015``
|
|
- ``Visual Studio 15 2017``
|
|
- ``Visual Studio 16 2019``
|
|
|
|
Any later version should also work.
|
|
|
|
You will now have a *Visual Studio Solution* in your build directory.
|
|
To run the unit tests build the ``RUN_TESTS`` project.
|
|
|
|
If you prefer a GUI the ``cmake`` line in the above example can
|
|
be replaced with::
|
|
|
|
cmake-gui ..
|
|
|
|
For command line help (including a list of available generators)
|
|
for CMake_ simply run::
|
|
|
|
cmake
|
|
|
|
To list available CMake_ settings (and what they are currently set to)
|
|
for the project, run::
|
|
|
|
cmake -LH ..
|
|
|
|
Windows (MinGW)
|
|
^^^^^^^^^^^^^^^
|
|
If you prefer using MinGW on Windows, make sure MinGW installed and ``{MinGW}/bin`` has been added to ``PATH``, then do the following commands:
|
|
|
|
.. parsed-literal::
|
|
|
|
<unpack>
|
|
cd jansson-|release|
|
|
|
|
md build
|
|
cd build
|
|
cmake -G "MinGW Makefiles" ..
|
|
mingw32-make
|
|
|
|
|
|
Mac OSX (Xcode)
|
|
^^^^^^^^^^^^^^^
|
|
If you prefer using Xcode instead of make files on OSX,
|
|
do the following. (Use the same steps as
|
|
for :ref:`Unix <build-cmake-unix>`)::
|
|
|
|
...
|
|
cmake -G "Xcode" ..
|
|
|
|
Additional CMake settings
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Shared library
|
|
""""""""""""""
|
|
By default the CMake_ project will generate build files for building the
|
|
static library. To build the shared version use::
|
|
|
|
...
|
|
cmake -DJANSSON_BUILD_SHARED_LIBS=1 ..
|
|
|
|
Changing install directory (same as autoconf --prefix)
|
|
""""""""""""""""""""""""""""""""""""""""""""""""""""""
|
|
Just as with the autoconf_ project you can change the destination directory
|
|
for ``make install``. The equivalent for autoconfs ``./configure --prefix``
|
|
in CMake_ is::
|
|
|
|
...
|
|
cmake -DCMAKE_INSTALL_PREFIX:PATH=/some/other/path ..
|
|
make install
|
|
|
|
.. _CMake: http://www.cmake.org
|
|
|
|
|
|
Android
|
|
-------
|
|
|
|
Jansson can be built for Android platforms. Android.mk is in the
|
|
source root directory. The configuration header file is located in the
|
|
``android`` directory in the source distribution.
|
|
|
|
|
|
Other Systems
|
|
-------------
|
|
|
|
On 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`` (which has some platform-specific
|
|
parameters that are normally filled in by the ``./configure``
|
|
script). 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_:
|
|
|
|
.. code-block:: shell
|
|
|
|
cc -o prog prog.c `pkg-config --cflags --libs jansson`
|
|
|
|
.. _pkg-config: http://pkg-config.freedesktop.org/
