Getting started
===============

Installing
----------


Linux
~~~~~

PyTango is available on linux as an official debian/ubuntu package:

.. sourcecode:: console

    $ sudo apt-get install python3-tango

RPM packages are also available for RHEL & CentOS:

.. hlist::
   :columns: 2

   * `CentOS 6 32bits <http://pubrepo.maxiv.lu.se/rpm/el6/x86_64/>`_
   * `CentOS 6 64bits <http://pubrepo.maxiv.lu.se/rpm/el6/x86_64/>`_
   * `CentOS 7 64bits <http://pubrepo.maxiv.lu.se/rpm/el7/x86_64/>`_
   * `Fedora 23 32bits <http://pubrepo.maxiv.lu.se/rpm/fc23/i/386/>`_
   * `Fedora 23 64bits <http://pubrepo.maxiv.lu.se/rpm/fc23/x86_64/>`_

PyPi
~~~~

You can also install the latest version from `PyPi`_.

First, make sure you have the following packages already installed (all of them
are available from the major official distribution repositories):

* `boost-python`_ (including boost-python-dev)
* `numpy`_

Then install PyTango either from pip:

.. sourcecode:: console

    $ pip install PyTango

or easy_install:

.. sourcecode:: console

    $ easy_install -U PyTango

Windows
~~~~~~~

First, make sure `Python`_ and `numpy`_ are installed.

PyTango team provides a limited set of binary PyTango distributables for
Windows XP/Vista/7/8. The complete list of binaries can be downloaded from
`PyPI`_.

Select the proper windows package, download it and finally execute the
installion wizard.

Compiling
---------

Linux
~~~~~

Since PyTango 9 the build system used to compile PyTango is the standard python
setuptools.

Besides the binaries for the three dependencies mentioned above, you also need
the development files for the respective libraries.

You can get the latest ``.tar.gz`` from `PyPI`_ or directly
the latest SVN checkout:

.. sourcecode:: console

    $ git clone https://github.com/tango-cs/pytango.git
    $ cd pytango
    $ python setup.py build
    $ sudo python setup.py install

This will install PyTango in the system python installation directory.
(Since PyTango9, :ref:`itango` has been removed to a separate project and it will not be installed with PyTango.)
If you whish to install in a different directory, replace the last line with:

.. sourcecode:: console

    $ # private installation to your user (usually ~/.local/lib/python<X>.<Y>/site-packages)
    $ python setup.py install --user

    $ # or specific installation directory
    $ python setup.py install --prefix=/home/homer/local

Windows
~~~~~~~

On windows, PyTango must be built using MS VC++.
Since it is rarely needed and the instructions are so complicated, I have
choosen to place the how-to in a separate text file. You can find it in the
source package under :file:`doc/windows_notes.txt`.

Testing
-------

To test the installation, import ``tango`` and check ``tango.Release.version``:

.. sourcecode:: console

    $ python -c "import tango; print(tango.Release.version)"
    9.3.3

Next steps: Check out the :ref:`pytango-quick-tour`.
