%poky; ] > This chapter describes how you need to prepare your system in order to use Toaster.

You first need to be sure your build system is set up to run the Yocto Project. See the "What You Need and How You Get It" section in the Yocto Project Quick Start for information on how to set up your system for the Yocto Project.

Toaster requires extra Python dependencies and daemon 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.

It is highly recommended that you use a Python virtual environment that allows you to maintain a dedicated Python executable and its own set of installed modules. Doing so separates the executable from the Python and modules provided by the operating system and therefore avoids any version conflicts. Follow these steps to set up your virtual environment. These steps assume a Ubuntu distribution: Install virtualenv: Install the supported python-virtualenv package from your distribution rather than using pip. $ sudo apt-get install python-virtualenv Create and Activate a Virtual Environment: $ virtualenv venv $ source venv/bin/activate

You need to install the packages that Toaster requires. Use this command: $ pip install -r bitbake/toaster-requirements.txt

Toaster depends on daemon. Depending on your distribution, how you install daemon differs: Debian-Based Systems: If you are running a Debian-based distribution, install daemon using the following command: $ sudo apt-get install daemon​ Non-Debian-Based Systems: If you are not running a Debian-based distribution (Redhat-based distribution such as Fedora), you need to download ​the file relevant to the architecture and then install daemon manually. Following are the commands for 64-bit distributions: $ wget http://libslack.org/daemon/download/daemon-0.6.4-1.x86_64.rpm $ sudo rpm -i daemon-0.6.4-1.x86_64.rpm Here are the commands for a 32-bit distribution: $ wget http://libslack.org/daemon/download/daemon-0.6.4-1.i686.rpm $ sudo rpm -i ​daemon-0.6.4-1.i686.rpm​
