Preparing to Use Toaster
************************

This chapter describes how you need to prepare your system in order to
use Toaster.

Setting Up the Basic System Requirements
========================================

Before you can use Toaster, you need to first set up your build system
to run the Yocto Project. To do this, follow the instructions in the
"`Preparing the Build
Host <&YOCTO_DOCS_DEV_URL;#dev-preparing-the-build-host>`__" section of
the Yocto Project Development Tasks Manual. For Ubuntu/Debian, you might
also need to do an additional install of pip3. $ sudo apt-get install
python3-pip

Establishing Toaster System Dependencies
========================================

Toaster requires extra Python dependencies in order to run. A Toaster
requirements file named ``toaster-requirements.txt`` defines the Python
dependencies. The requirements file is located in the ``bitbake``
directory, which is located in the root directory of the `Source
Directory <&YOCTO_DOCS_REF_URL;#source-directory>`__ (e.g.
``poky/bitbake/toaster-requirements.txt``). The dependencies appear in a
``pip``, install-compatible format.

.. _toaster-load-packages:

Install Toaster Packages
------------------------

You need to install the packages that Toaster requires. Use this
command: $ pip3 install --user -r bitbake/toaster-requirements.txt The
previous command installs the necessary Toaster modules into a local
python 3 cache in your ``$HOME`` directory. The caches is actually
located in ``$HOME/.local``. To see what packages have been installed
into your ``$HOME`` directory, do the following: $ pip3 list installed
--local If you need to remove something, the following works: $ pip3
uninstall PackageNameToUninstall
