<chapter id='toaster-manual-start'>
<title>Preparing to Use Toaster</title>
<para>
This chapter describes how you need to prepare your system in order to
use Toaster.
</para>
<section id='toaster-setting-up-the-basic-system-requirements'>
<title>Setting Up the Basic System Requirements</title>
<para>
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
"<ulink url='&YOCTO_DOCS_QS_URL;#packages'>The Build Host Packages</ulink>"
and
"<ulink url='&YOCTO_DOCS_QS_URL;#releases'>Yocto Project Release</ulink>"
sections in the Yocto Project Quick Start.
</para>
</section>
<section id='toaster-establishing-toaster-system-dependencies'>
<title>Establishing Toaster System Dependencies</title>
<para>
Toaster requires extra Python dependencies in order to run.
A Toaster requirements file named
<filename>toaster-requirements.txt</filename> defines the
Python dependencies.
The requirements file is located in the
<filename>bitbake</filename> directory, which is located in the
root directory of the
<ulink url='&YOCTO_DOCS_DEV_URL;#source-directory'>Source Directory</ulink>
(e.g. <filename>poky/bitbake/toaster-requirements.txt</filename>).
The dependencies appear in a <filename>pip</filename>,
install-compatible format.
</para>
<section id='toaster-virtual-environment'>
<title>Set Up a Python Virtual Environment</title>
<para>
Set up 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 Python and the
modules provided by the operating system.
This separation avoids any version conflicts.
<note>
Creating a virtual environment is not absolutely
necessary.
However, doing so is highly recommended.
</note>
</para>
<para>
Follow these steps to set up your virtual environment.
These steps assume a Ubuntu distribution:
<orderedlist>
<listitem><para><emphasis>Install <filename>virtualenv</filename>:</emphasis>
Install the supported
<filename>python-virtualenv</filename> package from your
distribution rather than using <filename>pip</filename>.
<literallayout class='monospaced'>
$ sudo apt-get install python-virtualenv
</literallayout>
</para></listitem>
<listitem><para><emphasis>Create and Activate a Virtual Environment:</emphasis>
<literallayout class='monospaced'>
$ virtualenv venv
$ source venv/bin/activate
</literallayout>
</para></listitem>
</orderedlist>
<note>
After setting up a virtual environment in
which to run Toaster, you must initialize that
virtual environment each time you want to start
Toaster.
Use the following to initialize the environment just
before you start Toaster:
<literallayout class='monospaced'>
$ source venv/bin/activate
</literallayout>
</note>
</para>
</section>
<section id='toaster-load-packages'>
<title>Install Toaster Packages</title>
<para>
You need to install the packages that Toaster requires.
Use this command:
<literallayout class='monospaced'>
$ pip install -r bitbake/toaster-requirements.txt
</literallayout>
</para>
</section>
<!-- Commenting this section out for now in case it needs to be used again.
<section id='toaster-install-daemon'>
<title>Install <filename>daemon</filename></title>
<para>
Toaster depends on
<ulink url='http://www.libslack.org/daemon/'><filename>daemon</filename></ulink>.
Depending on your distribution, how you install
<filename>daemon</filename> differs:
<itemizedlist>
<listitem><para><emphasis>Debian-Based Systems:</emphasis>
If you are running a Debian-based distribution,
install <filename>daemon</filename> using the
following command:
<literallayout class='monospaced'>
$ sudo apt-get install daemon
</literallayout>
</para></listitem>
<listitem><para><emphasis>Non-Debian-Based Systems:</emphasis>
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
<filename>daemon</filename> manually.
Following are the commands for 64-bit distributions:
<literallayout class='monospaced'>
$ 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
</literallayout>
Here are the commands for a 32-bit distribution:
<literallayout class='monospaced'>
$ wget http://libslack.org/daemon/download/daemon-0.6.4-1.i686.rpm
$ sudo rpm -i daemon-0.6.4-1.i686.rpm
</literallayout>
</para></listitem>
