Installing Sumo =============== Parts of sumo ------------- Sumo consists of scripts, python modules, documentation and configuration files. The distribution does not contain the configuration files since you have to adapt them to your development host. Examples of configuration files are shown further below. Sumo is available as a debian or rpm package, as a tar.gz or zip file and on pypi. The sections below describe all installation options. Requirements ------------ Sumo requires at least `Python `_ version 3.2.3 or newer. Sumo is tested on `debian `_ and `Fedora `_ linux distributions but should run on all linux distributions. It probably also runs on other flavours of unix, probably even MacOS, but this is not tested. It may run on windows, escpecially the `Cygwin `_ environment, but this is also not tested. Install from pypi with pip -------------------------- In order to install sumo with `pip `_, you use the command [1]_:: pip install EPICS-sumo .. [1] You may have to use ``pip3`` or ``pip-3.2`` or a similar command instead of ``pip`` on your system to use python 3. You find documentation for the usage of pip at `Installing Python Modules `_. Install from a debian package ----------------------------- There are packages for some of the recent debian versions. In order to see what debian version you use enter:: cat /etc/debian_version Download the package here: * `sumo downloads at Sourceforge `_ and install with:: dpkg -i The packages may or may not work for other debian versions, but this was not tested. As a last resort you may always install from source (see `Install from source (tar.gz or zip file)`_). Note that you have to *configure* sumo after installing it, see `The sumo configuration file`_. Install from a rpm package -------------------------- There are packages for some of the recent fedora versions. In order to see what fedora version you use enter:: cat /etc/fedora-release Download the package here: * `sumo downloads at Sourceforge `_ and install with:: rpm -ivh The packages may or may not work for other fedora versions, redhat or scientific linux but this was not tested. As a last resort you may always install from source (see `Install from source (tar.gz or zip file)`_). Note that you have to *configure* sumo after installing it, see `The sumo configuration file`_. Install from source (tar.gz or zip file) ---------------------------------------- Download the file here: * `sumo downloads at Sourceforge `_ unpack the tar.gz file with:: tar -xzf or unpack the zip file with:: unzip The sumo distribution contains the install script "setup.py". If you install sumo from source you always invoke this script with some command line options. The following chapters are just *examples* how you could install sumo. For a complete list of all possibilities see ``_. Install with:: python3 setup.py [options] Whenever ``python`` is mentioned in a command line in the following text remember that you may have to use ``python3`` instead. Install as root to default directories :::::::::::::::::::::::::::::::::::::: This method will install sumo on your systems default python library and binary directories. Advantages: - You don't have to modify environment variables in order to use sumo. - All users on your machine can easily use sumo. Disadvantages: - You must have root or administrator permissions to install sumo. - Files of sumo are mixed with other files from your system in the same directories making it harder to uninstall sumo. For installing sumo this way, as user "root" enter:: python setup.py install Install to a separate directory ::::::::::::::::::::::::::::::: In this case all files of sumo will be installed to a separate directory. Advantages: - All sumo files are below a directory you specify, making it easy to uninstall sumo. - If you have write access that the directory, you don't need root or administrator permissions. Disadvantages: - Each user on your machine who wants to use sumo must have the correct settings of the environment variables PATH and PYTHONPATH. For installing sumo this way, enter:: python setup.py install --prefix where is your install directory. In order to use sumo, you have to change the environment variables PATH and PYTHONPATH. Here is an example how you could do this:: export PATH=/bin:$PATH export PYTHONPATH=/lib/python/site-packages:$PYTHONPATH where is your install directory and is your python version number. You get your python version with this command:: python -c 'from sys import *;stdout.write("%s.%s\n"%version_info[:2])' You may want to add the environment settings ("export...") to your shell setup, e.g. $HOME/.bashrc or, if your are the system administrator, to the global shell setup. Install in your home :::::::::::::::::::: In this case all files of sumo are installed in a directory in your home called "sumo". Advantages: - All sumo files are below $HOME/sumo, making it easy to uninstall sumo. - You don't need root or administrator permissions. Disadvantages: - Only you can use this installation. - You need the correct settings of environment variables PATH and PYTHONPATH. For installing sumo this way, enter:: python setup.py install --home $HOME/sumo You must set your environment like this:: export PATH=$HOME/sumo/bin:$PATH export PYTHONPATH=$HOME/sumo/lib/python:$PYTHONPATH You may want to add these lines to your shell setup, e.g. $HOME/.bashrc. The sumo configuration file --------------------------- In order to use sumo on your system you should create a configuration file. The default name for this file is "sumo.config". See :doc:`configuration-files` for a complete description of configuration files. See :ref:`sumo.config examples ` for examples of configuration files. See :ref:`sumo config new ` for a command that creates a configuration file from a template provided with sumo.
