Installation
============
Prequisites
-----------
* `Python <http://www.python.org/>`_ 2.6 or higher,
* `Astropy <http://www.astropy.org/>`_
Binary packages
---------------
On Debian and debian-based systems (Ubuntu, Mint), python-cpl can be installed with the command
.. code-block:: sh
apt-get install python-cpl
Python CPL comes with the `Ubuntu <packages.ubuntu.com/python-cpl>`_
distribution since 12.04. Debian packages are in `Wheezy (Debian 7)
<http://packages.debian.org/wheezy/python-cpl>`_, `Squeeze (Debian 8)
<http://packages.debian.org/jessie/python-cpl>`_, and `Testing
<http://packages.debian.org/testing/python-cpl>`_
Source code
-----------
* `Python Package Index <http://pypi.python.org/pypi/python-cpl/>`_
* `Git repository <http://github.com/olebole/python-cpl>`_. To access, do a::
git clone git://github.com/olebole/python-cpl.git
This gives you the current version in the subdirectory :file:`python-cpl`.
To update to the current version of an existing repository, do a
``git pull`` in the :file:`python-cpl` directory.
For more detailed information, check the manual page of :manpage:`git(1)`
and the `github <http://github.com/olebole/python-cpl>`_ page of the project.
Compilation
-----------
For compilation, a C compiler is needed additionally to the software mentioned
above.
The installation follows the standard procedure used in python. On default,
the installation path :file:`/usr/local`. If using a non-standard installation
path, add the directory :file:`{PREFIX}/lib/python2.7/site-packages/`
(:file:`lib64/python2.7/site-packages/` on 64 bit systems) to your environment
variable :envvar:`PYTHONPATH` where where :file:`{PREFIX}` is the installation
path for the package.
In the source directory of python-cpl, run
.. code-block:: sh
python setup.py install --prefix=PREFIX
There are other options available as well; use the :option:`--help` option to
list them.
Test suite
----------
There are a number of tests defined in :file:`test/TestRecipe.py`:
.. code-block:: sh
python TestRecipe.py
The test recipe needs an installed CPL development environment.
The tests may print a memory corruption detection by glibc. This is normal,
since the tests also check this behaviour in the recipe.
Tests are also automatically buils by
`Travis CI <https://travis-ci.org/olebole/python-cpl>`_.
