Compiling and Installing Jansson
|
|
================================
|
|
|
|
This chapter explains how to compile and install the library itself.
|
|
|
|
|
|
Compiling and Installing from a Source Tarball
|
|
----------------------------------------------
|
|
|
|
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.

|
|
.. _automake: http://www.gnu.org/software/automake/
|
|
.. _libtool: http://www.gnu.org/software/libtool/
|
|
|
|
|
|
Compiling and Installing from Git
|
|
---------------------------------
|
|
|
|
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, Autotools 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 in the previous section.
|
|
|
|
|
|
Installing Prebuilt Binary Packages
|
|
-----------------------------------
|
|
|
|
Binary ``.deb`` packages for Ubuntu are available in the `Jansson
|
|
PPA`_ at Launchpad_. Follow the instructions in the PPA ("Read about
|
|
installing" link) to take the PPA into use. Then install the -dev
|
|
package::
|
|
|
|
apt-get install libjansson-dev
|
|
|
|
.. _Jansson PPA: http://launchpad.net/~petri/+archive/ppa
|
|
.. _Launchpad: http://launchpad.net/

|
Compiling Programs Using 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
|
