| Welcome to the Yocto Project Reference Manual! This manual provides |
| reference information for the current release of the Yocto Project, and |
| is most effectively 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. |
| Rather, use this manual to find variable definitions, class |
| descriptions, and so forth as needed during the course of using the |
| Yocto Project. |
| |
| For introductory information on the Yocto Project, see the |
| :yocto_home:`Yocto Project Website <>` and the |
| ":ref:`overview-manual/development-environment:the yocto project development environment`" |
| chapter in the Yocto Project Overview and Concepts Manual. |
| |
| If you want to use the Yocto Project to quickly build an image without |
| having to understand concepts, work through the |
| :doc:`/brief-yoctoprojectqs/index` document. You can find "how-to" |
| information in the :doc:`/dev-manual/index`. You can find Yocto Project overview |
| and conceptual information in the :doc:`/overview-manual/index`. |

| |
| .. note:: |
| |
| - While the Yocto Project Team attempts to ensure all Yocto Project |
| releases are one hundred percent compatible with each officially |
| supported Linux distribution, instances might exist where you |
| encounter a problem while using the Yocto Project on a specific |
| distribution. |
| |
| - Yocto Project releases are tested against the stable Linux |
| distributions in the above list. The Yocto Project should work |
| on other distributions but validation is not performed against |
| them. |
| |
| - In particular, the Yocto Project does not support and currently |
| has no plans to support rolling-releases or development |
| distributions due to their constantly changing nature. We welcome |
| patches and bug reports, but keep in mind that our priority is on |
| the supported platforms listed below. |
| |
| - You may use Windows Subsystem For Linux v2 to set up a build host |
| using Windows 10, but validation is not performed against build |
| hosts using WSLv2. |
| |
| - The Yocto Project is not compatible with WSLv1, it is |
| compatible but not officially supported nor validated with |
| WSLv2, if you still decide to use WSL please upgrade to WSLv2. |
| |
| - If you encounter problems, please go to :yocto_bugs:`Yocto Project |
| Bugzilla <>` and submit a bug. We are |
| interested in hearing about your experience. For information on |
| how to submit a bug, see the Yocto Project |
| :yocto_wiki:`Bugzilla wiki page </Bugzilla_Configuration_and_Bug_Tracking>` |
| and the ":ref:`dev-manual/common-tasks:submitting a defect against the yocto project`" |
| section in the Yocto Project Development Tasks Manual. |

| |
| Required Packages for the Build Host |
| ==================================== |
| |
| The list of packages you need on the host development system can be |
| large when covering all build scenarios using the Yocto Project. This |
| section describes required packages according to Linux distribution and |
| function. |
| |
| .. _ubuntu-packages: |
| |
| Ubuntu and Debian |
| ----------------- |
| |
| The following list shows the required packages by function given a |
| supported Ubuntu or Debian Linux distribution: |
| |
| .. note:: |
| |
| - If your build system has the ``oss4-dev`` package installed, you |
| might experience QEMU build failures due to the package installing |
| its own custom ``/usr/include/linux/soundcard.h`` on the Debian |
| system. If you run into this situation, either of the following |
| solutions exist: |
| :: |
| |
| $ sudo apt-get build-dep qemu |
| $ sudo apt-get remove oss4-dev |
| |
| - For Debian-8, ``python3-git`` and ``pylint3`` are no longer |
| available via ``apt-get``. |
| :: |
| |
| $ sudo pip3 install GitPython pylint==1.9.5 |
| |
| - *Essentials:* Packages needed to build an image on a headless system: |
| :: |
| |
| $ sudo apt-get install &UBUNTU_HOST_PACKAGES_ESSENTIAL; |
| |
| - *Documentation:* Packages needed if you are going to build out the |
| Yocto Project documentation manuals: |
| :: |
| |
| $ sudo apt-get install make python3-pip |
| &PIP3_HOST_PACKAGES_DOC; |
| |
| .. note:: |
| |
| It is currently not possible to build out documentation from Debian 8 |
| (Jessie) because of outdated ``pip3`` and ``python3``. ``python3-sphinx`` |
| is too outdated. |
| |
| Fedora Packages |
| --------------- |
| |
| The following list shows the required packages by function given a |
| supported Fedora Linux distribution: |
| |
| - *Essentials:* Packages needed to build an image for a headless |
| system: |
| :: |
| |
| $ sudo dnf install &FEDORA_HOST_PACKAGES_ESSENTIAL; |
| |
| - *Documentation:* Packages needed if you are going to build out the |
| Yocto Project documentation manuals: |
| :: |
| |
| $ sudo dnf install make python3-pip which |
| &PIP3_HOST_PACKAGES_DOC; |
| |
| openSUSE Packages |
| ----------------- |
| |
| The following list shows the required packages by function given a |
| supported openSUSE Linux distribution: |
| |
| - *Essentials:* Packages needed to build an image for a headless |
| system: |
| :: |
| |
| $ sudo zypper install &OPENSUSE_HOST_PACKAGES_ESSENTIAL; |
| |

| &PIP3_HOST_PACKAGES_DOC; |
| |
| |
| CentOS-7 Packages |
| ----------------- |
| |
| The following list shows the required packages by function given a |
| supported CentOS-7 Linux distribution: |
| |
| - *Essentials:* Packages needed to build an image for a headless |
| system: |
| :: |
| |
| $ sudo yum install &CENTOS7_HOST_PACKAGES_ESSENTIAL; |
| |
| .. note:: |
| |
| - Extra Packages for Enterprise Linux (i.e. ``epel-release``) is |
| a collection of packages from Fedora built on RHEL/CentOS for |
| easy installation of packages not included in enterprise Linux |
| by default. You need to install these packages separately. |
| |
| - The ``makecache`` command consumes additional Metadata from |
| ``epel-release``. |
| |
| - *Documentation:* Packages needed if you are going to build out the |
| Yocto Project documentation manuals: |
| :: |
| |
| $ sudo yum install make python3-pip which |
| &PIP3_HOST_PACKAGES_DOC; |
| |
| CentOS-8 Packages |
| ----------------- |
| |
| The following list shows the required packages by function given a |
| supported CentOS-8 Linux distribution: |

| |
| - Extra Packages for Enterprise Linux (i.e. ``epel-release``) is |
| a collection of packages from Fedora built on RHEL/CentOS for |
| easy installation of packages not included in enterprise Linux |
| by default. You need to install these packages separately. |
| |
| - The ``PowerTools`` repo provides additional packages such as |
| ``rpcgen`` and ``texinfo``. |
| |
| - The ``makecache`` command consumes additional Metadata from |
| ``epel-release``. |
| |
| - *Documentation:* Packages needed if you are going to build out the |
| Yocto Project documentation manuals: |
| :: |
| |
| $ sudo dnf install make python3-pip which |
| &PIP3_HOST_PACKAGES_DOC; |
| |
| Required Git, tar, Python and gcc Versions |
| ========================================== |
| |
| In order to use the build system, your host development system must meet |
| the following version requirements for Git, tar, and Python: |
| |
| - Git 1.8.3.1 or greater |
| |
| - tar 1.28 or greater |
| |
| - Python 3.5.0 or greater |
| |
| If your host development system does not meet all these requirements, |
| you can resolve this by installing a ``buildtools`` 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. |
| |
| In addition, your host development system must meet the following |
| version requirement for gcc: |
| |
| - gcc 5.0 or greater |
| |
| If your host development system does not meet this requirement, you can |
| resolve this by installing a ``buildtools-extended`` tarball that |
| contains additional tools, the equivalent of ``buildtools-essential``. |
| |
| Installing a Pre-Built ``buildtools`` Tarball with ``install-buildtools`` script |
| -------------------------------------------------------------------------------- |
| |
| The ``install-buildtools`` script is the easiest of the three methods by |
| which you can get these tools. It downloads a pre-built buildtools |
| installer and automatically installs the tools for you: |
| |
| 1. Execute the ``install-buildtools`` script. Here is an example: |
| :: |
| |
| $ cd poky |
| $ scripts/install-buildtools --without-extended-buildtools \ |
| --base-url &YOCTO_DL_URL;/releases/yocto \ |
| --release yocto-&DISTRO; \ |
| --installer-version &DISTRO; |
| |
| During execution, the buildtools tarball will be downloaded, the |
| checksum of the download will be verified, the installer will be run |
| for you, and some basic checks will be run to to make sure the |
| installation is functional. |
| |
| To avoid the need of ``sudo`` privileges, the ``install-buildtools`` |
| script will by default tell the installer to install in: |
| :: |
| |
| /path/to/poky/buildtools |
| |
| If your host development system needs the additional tools provided |
| in the ``buildtools-extended`` tarball, you can instead execute the |
| ``install-buildtools`` script with the default parameters: |
| :: |
| |
| $ cd poky |
| $ scripts/install-buildtools |
| |
| 2. Source the tools environment setup script by using a command like the |
| following: |
| :: |
| |
| $ source /path/to/poky/buildtools/environment-setup-x86_64-pokysdk-linux |
| |
| Of course, you need to supply your installation directory and be sure to |
| use the right file (i.e. i586 or x86_64). |
| |
| After you have sourced the setup script, the tools are added to |
| ``PATH`` and any other environment variables required to run the |
| tools are initialized. The results are working versions versions of |
| Git, tar, Python and ``chrpath``. And in the case of the |
| ``buildtools-extended`` tarball, additional working versions of tools |
| including ``gcc``, ``make`` and the other tools included in |
| ``packagegroup-core-buildessential``. |
| |
| Downloading a Pre-Built ``buildtools`` Tarball |
| ---------------------------------------------- |
| |
| Downloading and running a pre-built buildtools installer is the easiest |
| of the two methods by which you can get these tools: |
| |
| 1. Locate and download the ``*.sh`` at &YOCTO_RELEASE_DL_URL;/buildtools/ |
| |
| 2. Execute the installation script. Here is an example for the |
| traditional installer: |
| :: |
| |
| $ sh ~/Downloads/x86_64-buildtools-nativesdk-standalone-DISTRO.sh |
| |
| Here is an example for the extended installer: |
| :: |
| |
| $ sh ~/Downloads/x86_64-buildtools-extended-nativesdk-standalone-DISTRO.sh |
| |
| During execution, a prompt appears that allows you to choose the |
| installation directory. For example, you could choose the following: |
| ``/home/your-username/buildtools`` |
| |
| 3. Source the tools environment setup script by using a command like the |
| following: |
| :: |
| |
| $ source /home/your_username/buildtools/environment-setup-i586-poky-linux |
| |
| Of |
| course, you need to supply your installation directory and be sure to |
| use the right file (i.e. i585 or x86-64). |
| |
| After you have sourced the setup script, the tools are added to |
| ``PATH`` and any other environment variables required to run the |
| tools are initialized. The results are working versions versions of |
| Git, tar, Python and ``chrpath``. And in the case of the |
| ``buildtools-extended`` tarball, additional working versions of tools |
| including ``gcc``, ``make`` and the other tools included in |
| ``packagegroup-core-buildessential``. |
| |
| Building Your Own ``buildtools`` Tarball |
| ---------------------------------------- |
| |
| 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 ``.sh`` file and then take steps to transfer |
| and run it on a machine that does not meet the minimal Git, tar, and |
| Python (or gcc) requirements. |
| |
| Here are the steps to take to build and run your own buildtools |
| installer: |
| |
| 1. On the machine that is able to run BitBake, be sure you have set up |
| your build environment with the setup script |
| (:ref:`structure-core-script`). |
| |
| 2. Run the BitBake command to build the tarball: |
| :: |
| |
| $ bitbake buildtools-tarball |
| |
| or run the BitBake command to build the extended tarball: |
| :: |
| |
| $ bitbake buildtools-extended-tarball |
| |
| .. note:: |
| |
| The :term:`SDKMACHINE` variable in your ``local.conf`` file determines |
| whether you build tools for a 32-bit or 64-bit system. |
| |
| Once the build completes, you can find the ``.sh`` file that installs |
| the tools in the ``tmp/deploy/sdk`` subdirectory of the |
| :term:`Build Directory`. The installer file has the string |
| "buildtools" (or "buildtools-extended") in the name. |
| |
| 3. Transfer the ``.sh`` file from the build host to the machine that |
| does not meet the Git, tar, or Python (or gcc) requirements. |
| |
| 4. On the machine that does not meet the requirements, run the ``.sh`` |
| file to install the tools. Here is an example for the traditional |
| installer: |
| :: |
| |
| $ sh ~/Downloads/x86_64-buildtools-nativesdk-standalone-&DISTRO;.sh |
| |
| Here is an example for the extended installer: |
| :: |
| |
| $ sh ~/Downloads/x86_64-buildtools-extended-nativesdk-standalone-&DISTRO;.sh |
| |
| During execution, a prompt appears that allows you to choose the |
| installation directory. For example, you could choose the following: |
| ``/home/your_username/buildtools`` |
| |
| 5. Source the tools environment setup script by using a command like the |
| following: |
| :: |
| |
| $ source /home/your_username/buildtools/environment-setup-x86_64-poky-linux |
| |
| Of course, you need to supply your installation directory and be sure to |
| use the right file (i.e. i586 or x86_64). |
| |
| After you have sourced the setup script, the tools are added to |
| ``PATH`` and any other environment variables required to run the |
| tools are initialized. The results are working versions versions of |
| Git, tar, Python and ``chrpath``. And in the case of the |
| ``buildtools-extended`` tarball, additional working versions of tools |
| including ``gcc``, ``make`` and the other tools included in |
| ``packagegroup-core-buildessential``. |
