2 Preparing to Use Toaster

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

2.1 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” section of the Yocto Project Development Tasks Manual. For Ubuntu/Debian, you might also need to do an additional install of pip3.

$ sudo apt install python3-pip

2.2 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 (e.g. poky/bitbake/toaster-requirements.txt). The dependencies appear in a pip, install-compatible format.

2.2.1 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
