SPDX-License-Identifier: CC-BY-SA-2.0-UK + +******************* +System Requirements +******************* + +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:: + + For more information about the Yocto Project Documentation set, see + the :ref:`ref-manual/resources:links and related documentation` section. + +.. _detailed-supported-distros: + +Supported Linux Distributions +============================= + +Currently, the Yocto Project is supported on the following +distributions: + +- Ubuntu 16.04 (LTS) + +- Ubuntu 18.04 (LTS) + +- Ubuntu 20.04 + +- Fedora 30 + +- Fedora 31 + +- Fedora 32 + +- CentOS 7.x + +- CentOS 8.x + +- Debian GNU/Linux 8.x (Jessie) + +- Debian GNU/Linux 9.x (Stretch) + +- Debian GNU/Linux 10.x (Buster) + +- OpenSUSE Leap 15.1 + + +.. 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.

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``. |
