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
":ref:`dev-manual/start: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
:term:`Source Directory` (e.g.
``poky/bitbake/toaster-requirements.txt``). The dependencies appear in a
``pip``, install-compatible format.
Install Toaster Packages
You need to install the packages that Toaster requires. Use this
$ 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
