| Welcome to the Yocto Project Reference Manual! |
| This manual provides reference information for the current release |
| of the Yocto Project. |
| The manual is best used after you have an understanding |
| of the basics of the Yocto Project. |
| The manual is neither meant to be read as a starting point to the |
| Yocto Project nor read from start to finish. |
| Use this manual to find variable definitions, class |
| descriptions, and so forth as needed during the course of using |
| the Yocto Project. |

| <title>Required Git, tar, and Python Versions</title> |

| <para> |
| In order to use the build system, your host development system |
| must meet the following version requirements for Git, tar, and |
| Python: |
| <itemizedlist> |
| <listitem><para>Git 1.8.3.1 or greater</para></listitem> |

| <listitem><para>Python 3.4.0 or greater</para></listitem> |
| </itemizedlist> |
| </para> |
| |
| <para> |
| If your host development system does not meet all these requirements, |
| you can resolve this by installing a <filename>buildtools</filename> |
| tarball that contains these tools. |
| You can get the tarball one of two ways: download a pre-built |
| tarball or use BitBake to build the tarball. |
| </para> |

| <section id='downloading-a-pre-built-buildtools-tarball'> |
| <title>Downloading a Pre-Built <filename>buildtools</filename> Tarball</title> |
| |
| <para> |
| Downloading and running a pre-built buildtools installer is |
| the easiest of the two methods by which you can get these tools: |
| <orderedlist> |
| <listitem><para> |

| Here is an example: |
| <literallayout class='monospaced'> |
| $ sh ~/Downloads/x86_64-buildtools-nativesdk-standalone-&DISTRO;.sh |
| </literallayout> |
| During execution, a prompt appears that allows you to |
| choose the installation directory. |

| <literallayout class='monospaced'> |
| /home/<replaceable>your-username</replaceable>/buildtools |
| </literallayout> |
| </para></listitem> |
| <listitem><para> |
| Source the tools environment setup script by using a |

| <literallayout class='monospaced'> |
| $ source /home/<replaceable>your_username</replaceable>/buildtools/environment-setup-i586-poky-linux |

| <para> |
| After you have sourced the setup script, |
| the tools are added to <filename>PATH</filename> |

| Building and running your own buildtools installer applies |
| only when you have a build host that can already run BitBake. |
| In this case, you use that machine to build the |

| take steps to transfer and run it on a |
| machine that does not meet the minimal Git, tar, and Python |
| requirements. |

| <filename>.sh</filename> file that installs |
| the tools in the <filename>tmp/deploy/sdk</filename> |
| subdirectory of the |
