Installation on Linux
=====================

Using software packages
~~~~~~~~~~~~~~~~~~~~~~~

For installing distribution relative packages .deb/.rpm/...


Ubuntu / Kubuntu / Xubuntu / Lubuntu (Saucy and above)
------------------------------------------------------

#. Add one of the PPAs as you prefer

    :stable builds:
        $ sudo add-apt-repository ppa:kivy-team/kivy
    :nightly builds:
        $ sudo add-apt-repository ppa:kivy-team/kivy-daily

#. Update your package list using your package manager
    $ sudo apt-get update

#. Install Kivy

    :Python2 - **python-kivy**:
        $ sudo apt-get install python-kivy
    :Python3 - **python3-kivy**:
        $ sudo apt-get install python3-kivy
    :optionally the examples - **kivy-examples**:
        $ sudo apt-get install kivy-examples


Debian  (Jessie or newer)
-------------------------

#. Add one of the PPAs to your sources.list in apt manually or via Synaptic

    :stable builds:
        deb http://ppa.launchpad.net/kivy-team/kivy/ubuntu xenial main
    :daily builds:
        deb http://ppa.launchpad.net/kivy-team/kivy-daily/ubuntu xenial main

    **Notice**: Wheezy is not supported - You'll need to upgrade to Jessie at least!

#. Add the GPG key to your apt keyring by executing

    as user:

    ``sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys A863D2D6``

    as root:

    ``apt-key adv --keyserver keyserver.ubuntu.com --recv-keys A863D2D6``

#. Refresh your package list and install **python-kivy** and/or **python3-kivy** and optionally the examples
   found in **kivy-examples**


Linux Mint
----------

#. Find out on which Ubuntu release your installation is based on, using this
   `overview <https://linuxmint.com/download_all.php>`_.
#. Continue as described for Ubuntu above, depending on which version your
   installation is based on.


Bodhi Linux
-----------

#. Find out which version of the distribution you are running and use the table below
   to find out on which Ubuntu LTS it is based.

    :Bodhi 1:
        Ubuntu 10.04 LTS aka Lucid (No packages, just manual install)
    :Bodhi 2:
        Ubuntu 12.04 LTS aka Precise
    :Bodhi 3:
        Ubuntu 14.04 LTS aka Trusty
    :Bodhi 4:
        Ubuntu 16.04 LTS aka Xenial


2. Continue as described for Ubuntu above, depending on which version your installation is based on.


OpenSuSE
--------

#. To install kivy go to http://software.opensuse.org/package/python-Kivy and use the "1 Click Install" for your openSuse version. You might need to make the latest kivy version appear in the list by clicking on "Show unstable packages". We prefer to use packages by " devel:languages:python".

#. If you would like access to the examples, please select **python-Kivy-examples** in the upcoming installation wizard.


Gentoo
------

#. There is a kivy ebuild (kivy stable version)

   emerge Kivy

#. available USE-flags are:

   `cairo: Standard flag, let kivy use cairo graphical libraries.`
   `camera: Install libraries needed to support camera.`
   `doc: Standard flag, will make you build the documentation locally.`
   `examples: Standard flag, will give you kivy examples programs.`
   `garden: Install garden tool to manage user maintained widgets.`
   `gstreamer: Standard flag, kivy will be able to use audio/video streaming libraries.`
   `spell: Standard flag, provide enchant to use spelling in kivy apps.`

Other
-----

For other distros, we recommend installing via pip as shown below.


Installation in a Virtual Environment
=====================================


Common dependencies
~~~~~~~~~~~~~~~~~~~


Cython
------


Different versions of Kivy have only been tested up to a certain Cython version.
It may or may not work with a later version.

========   =============
Kivy       Cython
========   =============
1.8        0.20.2
1.9        0.21.2
1.9.1      0.23
1.10.0     0.25.2
========   =============


Dependencies with SDL2
~~~~~~~~~~~~~~~~~~~~~~


Ubuntu example
--------------

In the following command use "python" and "python-dev" for Python 2, or "python3" and "python3-dev" for Python 3.

::

    # Install necessary system packages
    sudo apt-get install -y \
        python-pip \
        build-essential \
        git \
        python \
        python-dev \
        ffmpeg \
        libsdl2-dev \
        libsdl2-image-dev \
        libsdl2-mixer-dev \
        libsdl2-ttf-dev \
        libportmidi-dev \
        libswscale-dev \
        libavformat-dev \
        libavcodec-dev \
        zlib1g-dev

    # Install gstreamer for audio, video (optional)
    sudo apt-get install -y \
        libgstreamer1.0 \
        gstreamer1.0-plugins-base \
        gstreamer1.0-plugins-good


**Note:**  Depending on your Linux version, you may receive error messages related to the "ffmpeg" package.
In this scenario, use "libav-tools \" in place of "ffmpeg \" (above), or use a PPA (as shown below):

::

- sudo add-apt-repository ppa:mc3man/trusty-media
- sudo apt-get update
- sudo apt-get install ffmpeg


Installation
------------


.. parsed-literal::

    # Make sure Pip, Virtualenv and Setuptools are updated
    sudo pip install --upgrade pip virtualenv setuptools

    # Then create a virtualenv named "kivyinstall" by either:

    # 1. using the default interpreter
    virtualenv --no-site-packages kivyinstall

    # or 2. using a specific interpreter
    # (this will use the interpreter in /usr/bin/python2.7)
    virtualenv --no-site-packages -p /usr/bin/python2.7 kivyinstall

    # Enter the virtualenv
    . kivyinstall/bin/activate

    # Use correct Cython version here
    pip install |cython_install|

    # Install stable version of Kivy into the virtualenv
    pip install kivy
    # For the development version of Kivy, use the following command instead
    # pip install git+https://github.com/kivy/kivy.git@master

    # If you want to install pygame backend instead of sdl2
    # you can install pygame using command below and enforce using
    # export USE_SDL2=0. If kivy's setup can't find sdl2 libs it will
    # automatically set this value to 0 then try to build using pygame.

    # Install a couple of dependencies for KivyCatalog
    pip install -U pygments docutils


.. _linux-run-app:


Start from the Command Line
~~~~~~~~~~~~~~~~~~~~~~~~~~~

We ship some examples that are ready-to-run. However, these examples are packaged inside the package.
This means you must first know where easy_install has installed your current kivy package,
and then go to the examples directory::

    $ python -c "import pkg_resources; print(pkg_resources.resource_filename('kivy', '../share/kivy-examples'))"

And you should have a path similar to::

    /usr/local/lib/python2.6/dist-packages/Kivy-1.0.4_beta-py2.6-linux-x86_64.egg/share/kivy-examples/

Then you can go to the example directory, and run it::

    # launch touchtracer
    $ cd <path to kivy-examples>
    $ cd demo/touchtracer
    $ python main.py

    # launch pictures
    $ cd <path to kivy-examples>
    $ cd demo/pictures
    $ python main.py

If you are familiar with Unix and symbolic links, you can create a link directly in your home directory
for easier access. For example:

#. Get the example path from the command line above
#. Paste into your console::

    $ ln -s <path to kivy-examples> ~/

#. Then, you can access to kivy-examples directly in your home directory::

    $ cd ~/kivy-examples

If you wish to start your Kivy programs as scripts (by typing `./main.py`) or by double-clicking them,
you will want to define the correct version of Python by linking to it. Something like::

    $ sudo ln -s /usr/bin/python2.7 /usr/bin/kivy

Or, if you are running Kivy inside a virtualenv, link to the Python interpreter for it, like::

    $ sudo ln -s /home/your_username/Envs/kivy/bin/python2.7 /usr/bin/kivy

Then, inside each main.py, add a new first line::

    #!/usr/bin/kivy

NOTE: Beware of Python files stored with Windows-style line endings (CR-LF). Linux will not ignore the <CR>
and will try to use it as part of the file name. This makes confusing error messages. Convert to Unix line endings.

Device permissions
~~~~~~~~~~~~~~~~~~

When you app starts, Kivy uses `Mtdev <http://wiki.ubuntu.com/Multitouch>`_ to
scan for available multi-touch devices to use for input. Access to these
devices is typically restricted to users or group with the appropriate
permissions.

If you do not have access to these devices, Kivy will log an error or warning
specifying these devices, normally something like::

    Permission denied:'/dev/input/eventX'

In order to use these devices, you need to grant the user or group permission.
This can be done via::

    $ sudo chmod u+r /dev/input/eventX

for the user or::

    $ sudo chmod g+r /dev/input/eventX

for the group. These permissions will only be effective for the duration of
your current session. A more permanent solution is to add the user to a group
that has these permissions. For example, in Ubuntu, you can add the user to
the 'input' group::

    $ sudo adduser $USER input

Note that you need to log out then back in again for these permissions to
be applied.
