This was a complete re-write of the YP Quick Start in an attempt
to streamline it, remove unecessary detail, and make it flow better
with the examples. In doing so, many manuals were affected due to
section headings being renamed, information being moved, etc. Here
is a list of the changes by manual:
Makefile - Removed two figures from TARFILE list for the
yocto-project-qs.
Added building-an-image.png to the ref-manual TARFILE list.
Added using-a-pre-build-image.png to the adt-manual TARFILE
list.
Repositioned 'eclipse' in the adt-manual TARFILE list.
adt-manual: Fixed a cross-reference so that it goes to the new
'Building Images' section that is within the YP QS.
Added new section 'Example Using Pre-Build Binaries and
QEMU' to hold the information that was formerly in YP QS.
dev-manual: Removed a cross-reference into the YP QS that promised how
to configure the most efficent build.
Changed a cross-reference into the YP QS from 'The Packages'
to 'The Build System Packages'.
Changed a cross-reference into the YP QS from 'Building an
Image' to 'Building Images'.
Changed a text reference from the YP QS to the adt-manual.
Moved the bit about getting YP files by using the YP website
from the YP QS to the dev-manual.
Changed a cross-reference into the YP QS from 'Using Pre-Built
Binaries and QEMU' to 'Example Using Pre-built Binaries and
QEMU', which was moved to the adt-manual.
ref-manual: Changed a cross-reference into the YP QS from 'What You
Need and How You Get It' to 'Setting Up to Use the Yocto Project'.
Moved the note about if your system has oss4-dev in the
packages area in the YP QS to the appropriate area in the
ref-manual.
Moved the introduction information regarding building an image
along with the figure from YP QS to the ref-manual's section on
building images.
toaster-manual: Changed a cross-reference into the YP QS from 'What You
Need and How You Get It' to 'Setting Up to Use the Yocto
Project'.
yocto-project-qs: Complete rewrite that changed many section headings and
removed much detail, which was placed in other manuals.

|
Welcome to the Yocto Project!
|
|
The Yocto Project is an open-source collaboration project whose
|
|
focus is developers of embedded Linux systems.
|
|
Among other things, the Yocto Project uses a build host based
|
|
on the OpenEmbedded (OE) project, which uses the
|
|
<ulink url='&YOCTO_DOCS_DEV_URL;#bitbake-term'>BitBake</ulink>
|
|
tool, to construct complete Linux images.
|
|
The BitBake and OE components are combined together to form
|
|
a reference build host, historically known as
|
|
<ulink url='&YOCTO_DOCS_DEV_URL;#poky'>Poky</ulink>.
|
|
</para>
|
|
|
|
<para>
|
|
If you do not have a system that runs Linux and you want to give
|
|
the Yocto Project a test run, you might consider using the Yocto
|
|
Project Build Appliance.
|
|
The Build Appliance allows you to build and boot a custom embedded
|
|
Linux image with the Yocto Project using a non-Linux development
|
|
system.
|
|
See the
|
|
<ulink url='https://www.yoctoproject.org/tools-resources/projects/build-appliance'>Yocto Project Build Appliance</ulink>
|
|
for more information.
|
|
</para>
|
|
|
|
<para>
|
|
This quick start is written so that you can quickly get a host
|
|
build host set up to use the Yocto Project and then build some
|
|
Linux images.
|
|
Rather than go into great detail about the Yocto Project and its
|
|
many capabilities, this quick start provides the minimal
|
|
information you need to try out the Yocto Project using a
|
|
supported Linux build host.
|
|
Reading and using the quick start should result in you having a
|
|
basic understanding of what the Yocto Project is and how to use
|
|
some of its core components.
|
|
You will also have worked through steps to produce two images:
|
|
one suitable for emulation and one that can be used on actual
|
|
hardware.
|
|
The examples highlight the ease with which you can use the
|
|
Yocto Project to create images for multiple types of hardware.

<para>
|
|
The Yocto Project through the OpenEmbedded build system provides an
|
|
open source development environment targeting the ARM, MIPS,
|
|
PowerPC, and x86 architectures for a variety of platforms
|
|
including x86-64 and emulated ones.
|
|
You can use components from the Yocto Project to design, develop,
|
|
build, debug, simulate, and test the complete software stack using
|
|
Linux, the X Window System, GTK+ frameworks, and Qt frameworks.

<para>
|
|
You can use the Yocto Project to generate images for many kinds
|
|
of devices.
|
|
As mentioned earlier, the Yocto Project supports creation of
|
|
reference images that you can boot within and emulate using QEMU.
|
|
The standard example machines target QEMU full-system
|
|
emulation for 32-bit and 64-bit variants of x86, ARM, MIPS, and
|
|
PowerPC architectures.
|
|
Beyond emulation, you can use the layer mechanism to extend
|
|
support to just about any platform that Linux can run on and that
|
|
a toolchain can target.
|
|
</para>
|
|
|
|
<para>
|
|
Another Yocto Project feature is the Sato reference User
|
|
Interface.
|
|
This optional UI that is based on GTK+ is intended for devices with
|
|
restricted screen sizes and is included as part of the
|
|
OpenEmbedded Core layer so that developers can test parts of the
|
|
software stack.

|
|
If your build host does not meet any of these three listed
|
|
version requirements, you can take steps to prepare the
|
|
system so that you can still use the Yocto Project.
|
|
See the
|
|
"<ulink url='&YOCTO_DOCS_REF_URL;#required-git-tar-and-python-versions'>Required Git, tar, and Python Versions</ulink>"

<section id='packages'>

|
<title>The Build Host Packages</title>
|
|
|
|
<para>
|
|
Required build host packages vary depending on your
|
|
build machine and what you want to do with the Yocto Project.
|
|
For example, if you want to build an image that can run
|
|
on QEMU in graphical mode (a minimal, basic build
|
|
requirement), then the build host package requirements
|
|
are different than if you want to build an image on a headless
|
|
system or build out the Yocto Project documentation set.
|
|
</para>
|
|
|
|
<para>
|
|
Collectively, the number of required packages is large
|
|
if you want to be able to cover all cases.
|
|
<note>
|
|
In general, you need to have root access and then install
|
|
the required packages.
|
|
Thus, the commands in the following section may or may
|
|
not work depending on whether or not your Linux
|
|
distribution has <filename>sudo</filename> installed.

The following list shows the required packages needed to build

|
|
The last requirement you need to meet before using the
|
|
Yocto Project is getting a Yocto Project release.
|
|
It is recommended that you get the latest Yocto Project release
|
|
by setting up (cloning in
|
|
<ulink url='&YOCTO_DOCS_DEV_URL;#git'>Git</ulink> terms) a
|
|
local copy of the <filename>poky</filename> Git repository on
|
|
your build host and then checking out the latest release.
|
|
Doing so allows you to easily update to newer Yocto Project
|
|
releases as well as contribute back to the Yocto Project.
|
|
</para>
|
|
|
|
<para>
|
|
Here is an example from an Ubuntu build host that clones the

By default, the build process searches for source code
|
|
using a pre-determined order through a set of
|
|
locations.
|
|
If you are working behind a firewall and your build
|
|
host is not set up for proxies, you could encounter
|
|
problems with the build process when fetching source
|
|
code (e.g. fetcher failures or Git failures).

If you do not know your proxy settings, consult your

A good starting point could also be to check your web
|
|
browser settings.

$ cd ~/poky

Git's <filename>checkout</filename> command checks out
|
|
the current Yocto Project release into a local branch
|
|
whose name matches the release (i.e.
|
|
<filename>&DISTRO_NAME;</filename>).
|
|
The local branch tracks the upstream branch of the
|
|
same name.
|
|
Creating your own branch based on the released
|
|
branch ensures you are using the latest files for
|
|
that release.

<filename>local.conf</filename> becomes available in
|
|
a <filename>conf</filename> subdirectory of the
|

Build Directory.
|

Before using BitBake to start the build, you can

look at this file and be sure your general

<listitem><para>

To help conserve disk space during builds,
|
|
you can add the following statement to your

|
project's configuration file, which for this
|
|
example is
|
|
<filename>poky/build/conf/local.conf</filename>.
|

Adding this statement deletes the work

recipe is built.

<trademark class='registered'>Intel</trademark>

easily changed through the

Another consideration before you build is the

package manager used when creating the image.

The default <filename>local.conf</filename>

You can control this configuration by using the

Depending on the number of processors and cores, the

amount of RAM, the speed of your Internet connection

Subsequent builds run much faster since parts of the

To configure the build, you edit the

<filename>bblayers.conf</filename> and

|
<filename>local.conf</filename> files, both of which are
|
|
located in the <filename>build/conf</filename> directory.

|
|
<para>Here is a quick way to make the edits.
|
|
The first command uses the

<filename>bitbake-layers add-layer</filename> command
|
|
to add the <filename>meta-intel</filename>
|
|
layer, which contains the <filename>intel-core*</filename>
|
|
BSPs to the build.
|
|
The second command selects the BSP by setting the

<ulink url='&YOCTO_DOCS_REF_URL;#var-MACHINE'><filename>MACHINE</filename></ulink>
|
|
variable.

Use the following command to build the minimal image for

MinnowBoard MAX.

|
Because configuration changes are minimal to set up for
|
|
this second build, the OpenEmbedded build system can
|
|
re-use files from previous builds as much as possible.
|

Re-using files means this second build will be much faster
