-Use ``devtool add`` to Add an Application
-----------------------------------------
-The ``devtool add`` command generates a new recipe based on existing
-source code. This command takes advantage of the
-:ref:`devtool-the-workspace-layer-structure`
-layer that many ``devtool`` commands use. The command is flexible enough
-to allow you to extract source code into both the workspace or a
-separate local Git repository and to use existing code that does not
-need to be extracted.
-Depending on your particular scenario, the arguments and options you use
-with ``devtool add`` form different combinations. The following diagram
-shows common development flows you would use with the ``devtool add``
-command:
-.. image:: figures/sdk-devtool-add-flow.png
-   :width: 100%
-#. *Generating the New Recipe*: The top part of the flow shows three
-   scenarios by which you could use ``devtool add`` to generate a recipe
-   based on existing source code.
-   In a shared development environment, it is typical for other
-   developers to be responsible for various areas of source code. As a
-   developer, you are probably interested in using that source code as
-   part of your development within the Yocto Project. All you need is
-   access to the code, a recipe, and a controlled area in which to do
-   your work.
-   Within the diagram, three possible scenarios feed into the
-   ``devtool add`` workflow:
-   -  *Left*: The left scenario in the figure represents a common
-      situation where the source code does not exist locally and needs
-      to be extracted. In this situation, the source code is extracted
-      to the default workspace --- you do not want the files in some
-      specific location outside of the workspace. Thus, everything you
-      need will be located in the workspace::
-         $ devtool add recipe fetchuri
-      With this command, ``devtool`` extracts the upstream
-      source files into a local Git repository within the ``sources``
-      folder. The command then creates a recipe named recipe and a
-      corresponding append file in the workspace. If you do not provide
-      recipe, the command makes an attempt to determine the recipe name.
-   -  *Middle*: The middle scenario in the figure also represents a
-      situation where the source code does not exist locally. In this
-      case, the code is again upstream and needs to be extracted to some
-      local area --- this time outside of the default workspace.
-      .. note::
-         If required, ``devtool`` always creates a Git repository locally
-         during the extraction.
-      Furthermore, the first positional argument ``srctree`` in this case
-      identifies where the ``devtool add`` command will locate the
-      extracted code outside of the workspace. You need to specify an
-      empty directory::
-         $ devtool add recipe srctree fetchuri
-      In summary, the source code is pulled from fetchuri and extracted into the
-      location defined by ``srctree`` as a local Git repository.
-      Within workspace, ``devtool`` creates a recipe named recipe along
-      with an associated append file.
-   -  *Right*: The right scenario in the figure represents a situation
-      where the ``srctree`` has been previously prepared outside of the
-      ``devtool`` workspace.
-      The following command provides a new recipe name and identifies
-      the existing source tree location::
-         $ devtool add recipe srctree
-      The command examines the source code and creates a recipe named
-      recipe for the code and places the recipe into the workspace.
-      Because the extracted source code already exists, ``devtool`` does
-      not try to relocate the source code into the workspace --- only the
-      new recipe is placed in the workspace.
-      Aside from a recipe folder, the command also creates an associated
-      append folder and places an initial ``*.bbappend`` file within.
-#. *Edit the Recipe*: You can use ``devtool edit-recipe`` to open up the
-   editor as defined by the ``$EDITOR`` environment variable and modify
-   the file::
-      $ devtool edit-recipe recipe
-   From within the editor, you can make modifications to the recipe that
-   take effect when you build it later.
-#. *Build the Recipe or Rebuild the Image*: The next step you take
-   depends on what you are going to do with the new code.
-   If you need to eventually move the build output to the target
-   hardware, use the following ``devtool`` command::
-      $ devtool build recipe
-   On the other hand, if you want an image to contain the recipe's
-   packages from the workspace for immediate deployment onto a device
-   (e.g. for testing purposes), you can use the ``devtool build-image``
-   command::
-      $ devtool build-image image
-#. *Deploy the Build Output*: When you use the ``devtool build`` command
-   to build out your recipe, you probably want to see if the resulting
-   build output works as expected on the target hardware.
-   .. note::
-      This step assumes you have a previously built image that is
-      already either running in QEMU or is running on actual hardware.
-      Also, it is assumed that for deployment of the image to the
-      target, SSH is installed in the image and, if the image is running
-      on real hardware, you have network access to and from your
-      development machine.
-   You can deploy your build output to that target hardware by using the
-   ``devtool deploy-target`` command::
-      $ devtool deploy-target recipe target
-   The target is a live target machine running as an SSH server.
-   You can, of course, also deploy the image you build to actual
-   hardware by using the ``devtool build-image`` command. However,
-   ``devtool`` does not provide a specific command that allows you to
-   deploy the image to actual hardware.
-#. *Finish Your Work With the Recipe*: The ``devtool finish`` command
-   creates any patches corresponding to commits in the local Git
-   repository, moves the new recipe to a more permanent layer, and then
-   resets the recipe so that the recipe is built normally rather than
-   from the workspace::
-      $ devtool finish recipe layer
-   .. note::
-      Any changes you want to turn into patches must be committed to the
-      Git repository in the source tree.
-   As mentioned, the ``devtool finish`` command moves the final recipe
-   to its permanent layer.
-   As a final process of the ``devtool finish`` command, the state of
-   the standard layers and the upstream source is restored so that you
-   can build the recipe from those areas rather than the workspace.
-   .. note::
-      You can use the ``devtool reset`` command to put things back should you
-      decide you do not want to proceed with your work. If you do use this
-      command, realize that the source tree is preserved.
-Use ``devtool modify`` to Modify the Source of an Existing Component
--------------------------------------------------------------------
-The ``devtool modify`` command prepares the way to work on existing code
-that already has a local recipe in place that is used to build the
-software. The command is flexible enough to allow you to extract code
-from an upstream source, specify the existing recipe, and keep track of
-and gather any patch files from other developers that are associated
-with the code.
-Depending on your particular scenario, the arguments and options you use
-with ``devtool modify`` form different combinations. The following
-diagram shows common development flows for the ``devtool modify``
-command:
-.. image:: figures/sdk-devtool-modify-flow.png
-   :width: 100%
-#. *Preparing to Modify the Code*: The top part of the flow shows three
-   scenarios by which you could use ``devtool modify`` to prepare to
-   work on source files. Each scenario assumes the following:
-   -  The recipe exists locally in a layer external to the ``devtool``
-      workspace.
-   -  The source files exist either upstream in an un-extracted state or
-      locally in a previously extracted state.
-   The typical situation is where another developer has created a layer
-   for use with the Yocto Project and their recipe already resides in
-   that layer. Furthermore, their source code is readily available
-   either upstream or locally.
-   -  *Left*: The left scenario in the figure represents a common
-      situation where the source code does not exist locally and it
-      needs to be extracted from an upstream source. In this situation,
-      the source is extracted into the default ``devtool`` workspace
-      location. The recipe, in this scenario, is in its own layer
-      outside the workspace (i.e. ``meta-``\ layername).
-      The following command identifies the recipe and, by default,
-      extracts the source files::
-         $ devtool modify recipe
-      Once ``devtool`` locates the recipe, ``devtool`` uses the recipe's
-      :term:`SRC_URI` statements to locate the source code and any local
-      patch files from other developers.
-      With this scenario, there is no ``srctree`` argument. Consequently, the
-      default behavior of the ``devtool modify`` command is to extract
-      the source files pointed to by the :term:`SRC_URI` statements into a
-      local Git structure. Furthermore, the location for the extracted
-      source is the default area within the ``devtool`` workspace. The
-      result is that the command sets up both the source code and an
-      append file within the workspace while the recipe remains in its
-      original location.
-      Additionally, if you have any non-patch local files (i.e. files
-      referred to with ``file://`` entries in :term:`SRC_URI` statement
-      excluding ``*.patch/`` or ``*.diff``), these files are copied to
-      an ``oe-local-files`` folder under the newly created source tree.
-      Copying the files here gives you a convenient area from which you
-      can modify the files. Any changes or additions you make to those
-      files are incorporated into the build the next time you build the
-      software just as are other changes you might have made to the
-      source.
-   -  *Middle*: The middle scenario in the figure represents a situation
-      where the source code also does not exist locally. In this case,
-      the code is again upstream and needs to be extracted to some local
-      area as a Git repository. The recipe, in this scenario, is again
-      local and in its own layer outside the workspace.
-      The following command tells ``devtool`` the recipe with which to
-      work and, in this case, identifies a local area for the extracted
-      source files that exists outside of the default ``devtool``
-      workspace::
-         $ devtool modify recipe srctree
-      .. note::
-         You cannot provide a URL for ``srctree`` using the ``devtool`` command.
-      As with all extractions, the command uses the recipe's :term:`SRC_URI`
-      statements to locate the source files and any associated patch
-      files. Non-patch files are copied to an ``oe-local-files`` folder
-      under the newly created source tree.
-      Once the files are located, the command by default extracts them
-      into ``srctree``.
-      Within workspace, ``devtool`` creates an append file for the
-      recipe. The recipe remains in its original location but the source
-      files are extracted to the location you provide with ``srctree``.
-   -  *Right*: The right scenario in the figure represents a situation
-      where the source tree (``srctree``) already exists locally as a
-      previously extracted Git structure outside of the ``devtool``
-      workspace. In this example, the recipe also exists elsewhere
-      locally in its own layer.
-      The following command tells ``devtool`` the recipe with which to
-      work, uses the "-n" option to indicate source does not need to be
-      extracted, and uses ``srctree`` to point to the previously extracted
-      source files::
-         $ devtool modify -n recipe srctree
-      If an ``oe-local-files`` subdirectory happens to exist and it
-      contains non-patch files, the files are used. However, if the
-      subdirectory does not exist and you run the ``devtool finish``
-      command, any non-patch files that might exist next to the recipe
-      are removed because it appears to ``devtool`` that you have
-      deleted those files.
-      Once the ``devtool modify`` command finishes, it creates only an
-      append file for the recipe in the ``devtool`` workspace. The
-      recipe and the source code remain in their original locations.
-#. *Edit the Source*: Once you have used the ``devtool modify`` command,
-   you are free to make changes to the source files. You can use any
-   editor you like to make and save your source code modifications.
-#. *Build the Recipe or Rebuild the Image*: The next step you take
-   depends on what you are going to do with the new code.
-   If you need to eventually move the build output to the target
-   hardware, use the following ``devtool`` command::
-      $ devtool build recipe
-   On the other hand, if you want an image to contain the recipe's
-   packages from the workspace for immediate deployment onto a device
-   (e.g. for testing purposes), you can use the ``devtool build-image``
-   command::
-      $ devtool build-image image
-#. *Deploy the Build Output*: When you use the ``devtool build`` command
-   to build out your recipe, you probably want to see if the resulting
-   build output works as expected on target hardware.
-   .. note::
-      This step assumes you have a previously built image that is
-      already either running in QEMU or running on actual hardware.
-      Also, it is assumed that for deployment of the image to the
-      target, SSH is installed in the image and if the image is running
-      on real hardware that you have network access to and from your
-      development machine.
-   You can deploy your build output to that target hardware by using the
-   ``devtool deploy-target`` command::
-      $ devtool deploy-target recipe target
-   The target is a live target machine running as an SSH server.
-   You can, of course, use other methods to deploy the image you built
-   using the ``devtool build-image`` command to actual hardware.
-   ``devtool`` does not provide a specific command to deploy the image
-   to actual hardware.
-#. *Finish Your Work With the Recipe*: The ``devtool finish`` command
-   creates any patches corresponding to commits in the local Git
-   repository, updates the recipe to point to them (or creates a
-   ``.bbappend`` file to do so, depending on the specified destination
-   layer), and then resets the recipe so that the recipe is built
-   normally rather than from the workspace::
-      $ devtool finish recipe layer
-   .. note::
-      Any changes you want to turn into patches must be staged and
-      committed within the local Git repository before you use the
-      ``devtool finish`` command.
-   Because there is no need to move the recipe, ``devtool finish``
-   either updates the original recipe in the original layer or the
-   command creates a ``.bbappend`` file in a different layer as provided
-   by layer. Any work you did in the ``oe-local-files`` directory is
-   preserved in the original files next to the recipe during the
-   ``devtool finish`` command.
-   As a final process of the ``devtool finish`` command, the state of
-   the standard layers and the upstream source is restored so that you
-   can build the recipe from those areas rather than from the workspace.
-   .. note::
-      You can use the ``devtool reset`` command to put things back should you
-      decide you do not want to proceed with your work. If you do use this
-      command, realize that the source tree is preserved.
-``devtool ide-sdk`` configures IDEs and bootstraps SDKs
-------------------------------------------------------
-The ``devtool ide-sdk`` command can provide an IDE configuration for IDEs when
-working on the source code of one or more recipes.
-Depending on the programming language, and the build system used by the recipe,
-the tools required for cross-development and remote debugging are different.
-For example:
-  A C/C++ project usually uses CMake or Meson.
-  A Python project uses setuptools or one of its successors.
-  A Rust project uses Cargo.
-Also, the IDE plugins needed for the integration of a build system with the
-IDE and the corresponding settings are usually specific to these build-systems.
-To hide all these details from the user, ``devtool ide-sdk`` does two things:
-  It generates any kind of SDK needed for cross-development and remote
-   debugging of the specified recipes.
-  It generates the configuration for the IDE (and the IDE plugins) for using
-   the cross-toolchain and remote debugging tools provided by the SDK directly
-   from the IDE.
-For supported build systems the configurations generated by ``devtool ide-sdk``
-combine the advantages of the ``devtool modify`` based workflow
-(see :ref:`using_devtool`) with the advantages of the simple Environment Setup
-script based workflow (see :ref:`running_the_ext_sdk_env`) provided by Yocto's
-SDK or eSDK:
-  The source code of the recipe is in the workspace created by
-   ``devtool modify`` or ``devtool add``.
-   Using ``devtool build``, ``devtool build-image``,
-   ``devtool deploy-target`` or ``bitbake`` is possible.
-   Also ``devtool ide-sdk`` can be used to update the SDK and the IDE
-   configuration at any time.
-  ``devtool ide-sdk`` aims to support multiple programming languages and
-   multiple IDEs natively. "Natively" means that the IDE is configured to call
-   the build tool (e.g. ``cmake`` or ``meson``) directly. This has several
-   advantages.
-   First of all, it is usually much faster to call for example ``cmake`` than
-   ``devtool build``.
-   It also allows to benefit from the very good integration that IDEs like
-   VSCode offer for tools like CMake or GDB.
-   
-   However, supporting many programming languages and multiple
-   IDEs is quite an elaborate and constantly evolving thing. Support for IDEs
-   is therefore implemented as plugins. Plugins can also be provided by
-   optional layers.
-So much about the introduction to the default mode of ``devtool sdk-ide`` which
-is called the "modified" mode because it uses the workspace created by
-``devtool modify`` and the per recipe :term:`Sysroots <Sysroot>` of BitBake.
-For some recipes and use cases, this default behavior of ``devtool ide-sdk``
-with full ``devtool`` and ``bitbake`` integration might not be suitable.
-To offer full feature parity with the SDK and the eSDK, ``devtool ide-sdk`` has
-a second mode called "shared" mode.
-If ``devtool ide-sdk`` is called with the ``--mode=shared`` option, it
-bootstraps an SDK directly from the BitBake environment, which offers the same
-Environment Setup script as described in :ref:`running_the_ext_sdk_env`.
-In addition to the (e)SDK installer-based setup, the IDE gets configured
-to use the shared :term:`Sysroots <Sysroot>` and the tools from the SDK.
-``devtool ide-sdk --mode=shared`` is basically a wrapper for the setup of the
-extensible SDK as described in :ref:`setting_up_ext_sdk_in_build`.
-The use of ``devtool ide-sdk`` is an alternative to using one of the SDK
-installers.
-``devtool ide-sdk`` allows the creation of SDKs that offer all the
-functionality of the SDK and the eSDK installers. Compared to the installers,
-however, the SDK created with ``devtool ide-sdk`` is much more flexible.
-For example, it is very easy to change the :term:`MACHINE` in the
-``local.conf`` file, update the layer meta data and then regenerate the SDK.
-Let's take a look at an example of how to use ``devtool ide-sdk`` in each of
-the two modes:
-#. *Modified mode*:
-   In order to use the ``devtool ide-sdk``, a few settings are needed. As a
-   starting example, the following lines of code can be added to the
-   ``local.conf`` file::
-      # Build the companion debug file system
-      IMAGE_GEN_DEBUGFS = "1"
-      # Optimize build time: with devtool ide-sdk the dbg tar is not needed
-      IMAGE_FSTYPES_DEBUGFS = ""
-      # Without copying the binaries into roofs-dbg, GDB does not find all source files.
-      IMAGE_CLASSES += "image-combined-dbg"
-      # SSH is mandatory, no password simplifies the usage
-      EXTRA_IMAGE_FEATURES += "\
-         ssh-server-openssh \
-         allow-empty-password \
-         allow-root-login \
-         empty-root-password \
-      "
-      # Remote debugging needs gdbserver on the target device
-      IMAGE_INSTALL:append = " gdbserver"
-      # Add the recipes which should be modified to the image
-      # Otherwise some dependencies might be missing.
-      IMAGE_INSTALL:append = " my-recipe"
-   Assuming the BitBake environment is set up correctly and a workspace has
-   been created for the recipe using ``devtool modify my-recipe`` or probably
-   even better by using ``devtool modify my-recipe --debug-build``, the
-   following command can create the SDK and the configuration for VSCode in
-   the recipe workspace::
-      $ devtool ide-sdk my-recipe core-image-minimal --target root@192.168.7.2
-   The command requires an image recipe (``core-image-minimal`` for this
-   example) that is used to create the SDK.
-   This firmware image should also be installed on the target device.
-   It is possible to pass multiple package recipes::
-      $ devtool ide-sdk my-recipe-1 my-recipe-2 core-image-minimal --target root@192.168.7.2
-   ``devtool ide-sdk`` tries to create an IDE configuration for all package
-   recipes.
-   What this command does exactly depends on the recipe, more precisely on the
-   build tool used by the recipe. The basic idea is to configure the IDE so
-   that it calls the build tool exactly as ``bitbake`` does.
-   For example, a CMake preset is created for a recipe that inherits
-   :ref:`ref-classes-cmake`. In the case of VSCode, CMake presets are supported
-   by the CMake Tools plugin. This is an example of how the build configuration
-   used by ``bitbake`` is exported to an IDE configuration that gives exactly
-   the same build results.
-   Support for remote debugging with seamless integration into the IDE is
-   important for a cross-SDK. ``devtool ide-sdk`` automatically generates the
-   necessary helper scripts for deploying the compiled artifacts to the target
-   device as well as the necessary configuration for the debugger and the IDE.
-   .. note::
-      To ensure that the debug symbols on the build machine match the binaries
-      running on the target device, it is essential that the image built by
-      ``devtool ide-sdk`` is running on the target device.
-   The default IDE is VSCode. Some hints about using VSCode:
-   -  VSCode can be used to work on the BitBake recipes or the application
-      source code.
-      Usually there is one instance of VSCode running in the folder where the
-      BitBake recipes are. This instance has the
-      `Yocto Project BitBake plugin <https://marketplace.visualstudio.com/items?itemName=yocto-project.yocto-bitbake>`_
-      running.
-      .. warning::
-         Some VSCode plugins (Python, BitBake and others) need a reasonable
-         configuration to work as expected. Otherwise, some plugins try to
-         index the build directory of BitBake, which keeps your system quite
-         busy until an out of memory exception stops this nonsense.
-         Other plugins, such as the BitBake plugin, do not behave as expected.
-         To work around such issues, the ``oe-init-build-env`` script creates
-         an initial ``.vscode/settings.json`` file if ``code`` can be found
-         and the ``.vscode`` folder does not yet exist.
-         It is best to run ``oe-init-build-env`` once before starting VSCode.
-         An alternative approach is to use a build folder outside the layers,
-         e.g. ``oe-init-build-env ../build``.
-      The BitBake plugin also offers to create devtool workspaces and run
-      ``devtool ide-sdk`` with a few mouse clicks.
-      Of course, issuing commands in the terminal works as well.
-   -  To work on the source code of a recipe another instance of VSCode is
-      started in the recipe's workspace. Example::
-         code build/workspace/sources/my-recipe
-      This instance of VSCode uses plugins that are useful for the development
-      of the application. ``devtool ide-sdk`` generates the necessary
-      ``extensions.json``, ``settings.json``, ``tasks.json``and ``launch.json``
-      configuration files for all the involved plugins.
-      When the source code folder present in the workspace folder is opened in
-      VSCode for the first time, a pop-up message recommends installing the
-      required plugins.
-      After accepting the installation of the plugins, working with the source
-      code or some debugging tasks should work as usual with VSCode.
-      Starting the VSCode instances in the recipe workspace folders can also be
-      done by a mouse click on the recipe workspaces in the first VSCode
-      instance.
-   -  To work with CMake press ``Ctrl + Shift + p``, type ``cmake``. This will
-      show some possible commands like selecting a CMake preset, compiling or
-      running CTest.
-      For recipes inheriting :ref:`ref-classes-cmake-qemu` rather than
-      :ref:`ref-classes-cmake`, executing cross-compiled unit tests on the host
-      can be supported transparently with QEMU user-mode.
-   -  To work with Meson press ``Ctrl + Shift + p``, type ``meson``. This will
-      show some possible commands like compiling or executing the unit tests.
-      A note on running cross-compiled unit tests on the host: Meson enables
-      support for QEMU user mode by default. It is expected that the execution
-      of the unit tests from the IDE will work without any additional steps,
-      given that the code is suitable for the execution on the host machine.
-   -  For the deployment to the target device, just press ``Ctrl + Shift + p``,
-      type ``task``.  Select ``install && deploy-target``.
-   -  For remote debugging, switch to the debugging view by pressing the "play"
-      button with the ``bug icon`` on the left side. This will provide a green
-      play button with a drop-down list where a debug configuration can be
-      selected.  After selecting one of the generated configurations, press the
-      "play" button.
-      Starting a remote debugging session automatically initiates the
-      deployment to the target device. If this is not desired, the
-      ``"dependsOn": ["install && deploy-target...]`` parameter of the tasks
-      with ``"label": "gdbserver start...`` can be removed from the
-      ``tasks.json`` file.
-      VSCode supports GDB with many different setups and configurations for
-      many different use cases.  However, most of these setups have some
-      limitations when it comes to cross-development, support only a few target
-      architectures or require a high performance target device. Therefore
-      ``devtool ide-sdk`` supports the classic, generic setup with GDB on the
-      development host and gdbserver on the target device.
-      Roughly summarized, this means:
-      -  The binaries are copied via SSH to the remote target device by a
-         script referred by ``tasks.json``.
-      -  gdbserver is started on the remote target device via SSH by a script
-         referred by ``tasks.json``.
-         Changing the parameters that are passed to the debugging executable
-         requires modifying the generated script. The script is located at
-         ``oe-scripts/gdbserver_*``. Defining the parameters in the ``args``
-         field in the ``launch.json`` file does not work.
-      -  VSCode connects to gdbserver as documented in
-         `Remote debugging or debugging with a local debugger server
-         <https://code.visualstudio.com/docs/cpp/launch-json-reference#_remote-debugging-or-debugging-with-a-local-debugger-server>`__.
-   Additionally ``--ide=none`` is supported. With the ``none`` IDE parameter,
-   some generic configuration files like ``gdbinit`` files and some helper
-   scripts starting gdbserver remotely on the target device as well as the GDB
-   client on the host are generated.
-   Here is a usage example for the ``cmake-example`` recipe from the
-   ``meta-selftest`` layer which inherits :ref:`ref-classes-cmake-qemu`:
-   .. code-block:: sh
-      # Create the SDK
-      devtool modify cmake-example --debug-build

-#. *Shared sysroots mode*
-   Creating an SDK with shared :term:`Sysroots <Sysroot>` that contains all the
-   dependencies needed to work with ``my-recipe`` is possible with the following
-   example command::
-      $ devtool ide-sdk --mode=shared my-recipe
-   For VSCode the cross-toolchain is exposed as a CMake kit. CMake kits are
-   defined in ``~/.local/share/CMakeTools/cmake-tools-kits.json``.
-   The following example shows how the cross-toolchain can be selected in
-   VSCode. First of all we need a folder containing a CMake project.
-   For this example, let's create a CMake project and start VSCode::
-      mkdir kit-test
-      echo "project(foo VERSION 1.0)" > kit-test/CMakeLists.txt
-      code kit-test
-   If there is a CMake project in the workspace, cross-compilation is
-   supported:
-   - Press ``Ctrl + Shift + P``, type ``CMake: Scan for Kits``
-   - Press ``Ctrl + Shift + P``, type ``CMake: Select a Kit``
-   Finally most of the features provided by CMake and the IDE should be
-   available.
-   Other IDEs than VSCode are supported as well. However,
-   ``devtool ide-sdk --mode=shared --ide=none my-recipe`` is currently
-   just a simple wrapper for the setup of the extensible SDK, as described in
-   :ref:`setting_up_ext_sdk_in_build`.
-Use ``devtool upgrade`` to Create a Version of the Recipe that Supports a Newer Version of the Software
-------------------------------------------------------------------------------------------------------
-The ``devtool upgrade`` command upgrades an existing recipe to that of a
-more up-to-date version found upstream. Throughout the life of software,
-recipes continually undergo version upgrades by their upstream
-publishers. You can use the ``devtool upgrade`` workflow to make sure
-your recipes you are using for builds are up-to-date with their upstream
-counterparts.
-.. note::
-   Several methods exist by which you can upgrade recipes ---
-   ``devtool upgrade`` happens to be one. You can read about all the methods by
-   which you can upgrade recipes in the
-   :ref:`dev-manual/upgrading-recipes:upgrading recipes` section of the Yocto
-   Project Development Tasks Manual.
-The ``devtool upgrade`` command is flexible enough to allow you to specify
-source code revision and versioning schemes, extract code into or out of the
-``devtool`` :ref:`devtool-the-workspace-layer-structure`, and work with any
-source file forms that the
-:ref:`bitbake-user-manual/bitbake-user-manual-fetching:fetchers` support.
-The following diagram shows the common development flow used with the
-``devtool upgrade`` command:
-.. image:: figures/sdk-devtool-upgrade-flow.png
-   :width: 100%
-#. *Initiate the Upgrade*: The top part of the flow shows the typical
-   scenario by which you use the ``devtool upgrade`` command. The
-   following conditions exist:
-   -  The recipe exists in a local layer external to the ``devtool``
-      workspace.
-   -  The source files for the new release exist in the same location
-      pointed to by :term:`SRC_URI`
-      in the recipe (e.g. a tarball with the new version number in the
-      name, or as a different revision in the upstream Git repository).
-   A common situation is where third-party software has undergone a
-   revision so that it has been upgraded. The recipe you have access to
-   is likely in your own layer. Thus, you need to upgrade the recipe to
-   use the newer version of the software::
-      $ devtool upgrade -V version recipe
-   By default, the ``devtool upgrade`` command extracts source
-   code into the ``sources`` directory in the
-   :ref:`devtool-the-workspace-layer-structure`.
-   If you want the code extracted to any other location, you need to
-   provide the ``srctree`` positional argument with the command as follows::
-      $ devtool upgrade -V version recipe srctree
-   .. note::
-      In this example, the "-V" option specifies the new version. If you
-      don't use "-V", the command upgrades the recipe to the latest
-      version.
-   If the source files pointed to by the :term:`SRC_URI` statement in the
-   recipe are in a Git repository, you must provide the "-S" option and
-   specify a revision for the software.
-   Once ``devtool`` locates the recipe, it uses the :term:`SRC_URI` variable
-   to locate the source code and any local patch files from other
-   developers. The result is that the command sets up the source code,
-   the new version of the recipe, and an append file all within the
-   workspace.
-   Additionally, if you have any non-patch local files (i.e. files
-   referred to with ``file://`` entries in :term:`SRC_URI` statement
-   excluding ``*.patch/`` or ``*.diff``), these files are copied to an
-   ``oe-local-files`` folder under the newly created source tree.
-   Copying the files here gives you a convenient area from which you can
-   modify the files. Any changes or additions you make to those files
-   are incorporated into the build the next time you build the software
-   just as are other changes you might have made to the source.
-#. *Resolve any Conflicts created by the Upgrade*: Conflicts could happen
-   after upgrading the software to a new version. Conflicts occur
-   if your recipe specifies some patch files in :term:`SRC_URI` that
-   conflict with changes made in the new version of the software. For
-   such cases, you need to resolve the conflicts by editing the source
-   and following the normal ``git rebase`` conflict resolution process.
-   Before moving onto the next step, be sure to resolve any such
-   conflicts created through use of a newer or different version of the
-   software.
-#. *Build the Recipe or Rebuild the Image*: The next step you take
-   depends on what you are going to do with the new code.
-   If you need to eventually move the build output to the target
-   hardware, use the following ``devtool`` command::
-      $ devtool build recipe
-   On the other hand, if you want an image to contain the recipe's
-   packages from the workspace for immediate deployment onto a device
-   (e.g. for testing purposes), you can use the ``devtool build-image``
-   command::
-      $ devtool build-image image
-#. *Deploy the Build Output*: When you use the ``devtool build`` command
-   or ``bitbake`` to build your recipe, you probably want to see if the
-   resulting build output works as expected on target hardware.
-   .. note::
-      This step assumes you have a previously built image that is
-      already either running in QEMU or running on actual hardware.
-      Also, it is assumed that for deployment of the image to the
-      target, SSH is installed in the image and if the image is running
-      on real hardware that you have network access to and from your
-      development machine.
-   You can deploy your build output to that target hardware by using the
-   ``devtool deploy-target`` command::
-      $ devtool deploy-target recipe target
-   The target is a live target machine running as an SSH server.
-   You can, of course, also deploy the image you build using the
-   ``devtool build-image`` command to actual hardware. However,
-   ``devtool`` does not provide a specific command that allows you to do
-   this.
-#. *Finish Your Work With the Recipe*: The ``devtool finish`` command
-   creates any patches corresponding to commits in the local Git
-   repository, moves the new recipe to a more permanent layer, and then
-   resets the recipe so that the recipe is built normally rather than
-   from the workspace.
-   Any work you did in the ``oe-local-files`` directory is preserved in
-   the original files next to the recipe during the ``devtool finish``
-   command.
-   If you specify a destination layer that is the same as the original
-   source, then the old version of the recipe and associated files are
-   removed prior to adding the new version::
-      $ devtool finish recipe layer
-   .. note::
-      Any changes you want to turn into patches must be committed to the
-      Git repository in the source tree.
-   As a final process of the ``devtool finish`` command, the state of
-   the standard layers and the upstream source is restored so that you
-   can build the recipe from those areas rather than the workspace.
-   .. note::
-      You can use the ``devtool reset`` command to put things back should you
-      decide you do not want to proceed with your work. If you do use this
-      command, realize that the source tree is preserved.
-A Closer Look at ``devtool add``
-================================
-The ``devtool add`` command automatically creates a recipe based on the
-source tree you provide with the command. Currently, the command has
-support for the following:
-  Autotools (``autoconf`` and ``automake``)
-  CMake
-  Scons
-  ``qmake``
-  Plain ``Makefile``
-  Out-of-tree kernel module
-  Binary package (i.e. "-b" option)
-  Node.js module
-  Python modules that use ``setuptools`` or ``distutils``
-Apart from binary packages, the determination of how a source tree
-should be treated is automatic based on the files present within that
-source tree. For example, if a ``CMakeLists.txt`` file is found, then
-the source tree is assumed to be using CMake and is treated accordingly.
-.. note::
-   In most cases, you need to edit the automatically generated recipe in
-   order to make it build properly. Typically, you would go through
-   several edit and build cycles until the recipe successfully builds.
-   Once the recipe builds, you could use possible further iterations to
-   test the recipe on the target device.
-The remainder of this section covers specifics regarding how parts of
-the recipe are generated.
-Name and Version
----------------
-If you do not specify a name and version on the command line,
-``devtool add`` uses various metadata within the source tree in an
-attempt to determine the name and version of the software being built.
-Based on what the tool determines, ``devtool`` sets the name of the
-created recipe file accordingly.
-If ``devtool`` cannot determine the name and version, the command prints
-an error. For such cases, you must re-run the command and provide the
-name and version, just the name, or just the version as part of the
-command line.
-Sometimes the name or version determined from the source tree might be
-incorrect. For such a case, you must reset the recipe::
-   $ devtool reset -n recipename
-After running the ``devtool reset`` command, you need to
-run ``devtool add`` again and provide the name or the version.
-Dependency Detection and Mapping
--------------------------------
-The ``devtool add`` command attempts to detect build-time dependencies and map
-them to other recipes in the system. During this mapping, the command fills in
-the names of those recipes as part of the :term:`DEPENDS` variable within the
-recipe. If a dependency cannot be mapped, ``devtool`` places a comment
-in the recipe indicating such. The inability to map a dependency can
-result from naming not being recognized or because the dependency simply
-is not available. For cases where the dependency is not available, you
-must use the ``devtool add`` command to add an additional recipe that
-satisfies the dependency. Once you add that recipe, you need to update
-the :term:`DEPENDS` variable in the original recipe to include the new
-recipe.
-If you need to add runtime dependencies, you can do so by adding the
-following to your recipe::
-   RDEPENDS:${PN} += "dependency1 dependency2 ..."
-.. note::
-   The ``devtool add`` command often cannot distinguish between mandatory and
-   optional dependencies. Consequently, some of the detected dependencies might
-   in fact be optional. When in doubt, consult the documentation or the
-   configure script for the software the recipe is building for further
-   details. In some cases, you might find you can substitute the
-   dependency with an option that disables the associated functionality
-   passed to the configure script.
-License Detection
-----------------
-The ``devtool add`` command attempts to determine if the software you are
-adding is able to be distributed under a common, open-source license. If
-so, the command sets the :term:`LICENSE` value accordingly.
-You should double-check the value added by the command against the
-documentation or source files for the software you are building and, if
-necessary, update that :term:`LICENSE` value.
-The ``devtool add`` command also sets the :term:`LIC_FILES_CHKSUM`
-value to point to all files that appear to be license-related. Realize
-that license statements often appear in comments at the top of source
-files or within the documentation. In such cases, the command does not
-recognize those license statements. Consequently, you might need to
-amend the :term:`LIC_FILES_CHKSUM` variable to point to one or more of those
-comments if present. Setting :term:`LIC_FILES_CHKSUM` is particularly
-important for third-party software. The mechanism attempts to ensure
-correct licensing should you upgrade the recipe to a newer upstream
-version in future. Any change in licensing is detected and you receive
-an error prompting you to check the license text again.
-If the ``devtool add`` command cannot determine licensing information,
-``devtool`` sets the :term:`LICENSE` value to "CLOSED" and leaves the
-:term:`LIC_FILES_CHKSUM` value unset. This behavior allows you to continue
-with development even though the settings are unlikely to be correct in
-all cases. You should check the documentation or source files for the
-software you are building to determine the actual license.
-Adding Makefile-Only Software
-----------------------------
-The use of Make by itself is very common in both proprietary and
-open-source software. Unfortunately, Makefiles are often not written
-with cross-compilation in mind. Thus, ``devtool add`` often cannot do
-very much to ensure that these Makefiles build correctly. It is very
-common, for example, to explicitly call ``gcc`` instead of using the
-:term:`CC` variable. Usually, in a
-cross-compilation environment, ``gcc`` is the compiler for the build
-host and the cross-compiler is named something similar to
-``arm-poky-linux-gnueabi-gcc`` and might require arguments (e.g. to
-point to the associated sysroot for the target machine).
-When writing a recipe for Makefile-only software, keep the following in
-mind:
-  You probably need to patch the Makefile to use variables instead of
-   hardcoding tools within the toolchain such as ``gcc`` and ``g++``.
-  The environment in which Make runs is set up with various standard
-   variables for compilation (e.g. :term:`CC`, :term:`CXX`, and so forth) in a
-   similar manner to the environment set up by the SDK's environment
-   setup script. One easy way to see these variables is to run the
-   ``devtool build`` command on the recipe and then look in
-   ``oe-logs/run.do_compile``. Towards the top of this file, there is
-   a list of environment variables that are set. You can take
-   advantage of these variables within the Makefile.
-  If the Makefile sets a default for a variable using "=", that default
-   overrides the value set in the environment, which is usually not
-   desirable. For this case, you can either patch the Makefile so it
-   sets the default using the "?=" operator, or you can alternatively
-   force the value on the ``make`` command line. To force the value on
-   the command line, add the variable setting to
-   :term:`EXTRA_OEMAKE` or
-   :term:`PACKAGECONFIG_CONFARGS`
-   within the recipe. Here is an example using :term:`EXTRA_OEMAKE`::
-      EXTRA_OEMAKE += "'CC=${CC}' 'CXX=${CXX}'"
-   In the above example,
-   single quotes are used around the variable settings as the values are
-   likely to contain spaces because required default options are passed
-   to the compiler.
-  Hardcoding paths inside Makefiles is often problematic in a
-   cross-compilation environment. This is particularly true because
-   those hardcoded paths often point to locations on the build host and
-   thus will either be read-only or will introduce contamination into
-   the cross-compilation because they are specific to the build host
-   rather than the target. Patching the Makefile to use prefix variables
-   or other path variables is usually the way to handle this situation.
-  Sometimes a Makefile runs target-specific commands such as
-   ``ldconfig``. For such cases, you might be able to apply patches that
-   remove these commands from the Makefile.
-Adding Native Tools
-------------------
-Often, you need to build additional tools that run on the :term:`Build Host`
-as opposed to the target. You should indicate this requirement by using one of
-the following methods when you run ``devtool add``:
-  Specify the name of the recipe such that it ends with "-native".
-   Specifying the name like this produces a recipe that only builds for
-   the build host.
-  Specify the "--also-native" option with the ``devtool add``
-   command. Specifying this option creates a recipe file that still
-   builds for the target but also creates a variant with a "-native"
-   suffix that builds for the build host.
-.. note::
-   If you need to add a tool that is shipped as part of a source tree
-   that builds code for the target, you can typically accomplish this by
-   building the native and target parts separately rather than within
-   the same compilation process. Realize though that with the
-   "--also-native" option, you can add the tool using just one
-   recipe file.
-Adding Node.js Modules
----------------------
-You can use the ``devtool add`` command two different ways to add
-Node.js modules: through ``npm`` or from a repository or local source.
-Use the following form to add Node.js modules through ``npm``::
-   $ devtool add "npm://registry.npmjs.org;name=forever;version=0.15.1"
-The name and
-version parameters are mandatory. Lockdown and shrinkwrap files are
-generated and pointed to by the recipe in order to freeze the version
-that is fetched for the dependencies according to the first time. This
-also saves checksums that are verified on future fetches. Together,
-these behaviors ensure the reproducibility and integrity of the build.
-.. note::
-   -  You must use quotes around the URL. ``devtool add`` does not
-      require the quotes, but the shell considers ";" as a splitter
-      between multiple commands. Thus, without the quotes,
-      ``devtool add`` does not receive the other parts, which results in
-      several "command not found" errors.
-   -  In order to support adding Node.js modules, a ``nodejs`` recipe
-      must be part of your SDK.
-As mentioned earlier, you can also add Node.js modules directly from a
-repository or local source tree. To add modules this way, use
-``devtool add`` in the following form::
-   $ devtool add https://github.com/diversario/node-ssdp
-In this example, ``devtool`` fetches the specified Git repository, detects the
-code as Node.js code, fetches dependencies using ``npm``, and sets
-:term:`SRC_URI` accordingly.
-Working With Recipes
-====================
-When building a recipe using the ``devtool build`` command, the typical
-build progresses as follows:
-#. Fetch the source
-#. Unpack the source
-#. Configure the source
-#. Compile the source
-#. Install the build output
-#. Package the installed output
-For recipes in the workspace, fetching and unpacking is disabled as the
-source tree has already been prepared and is persistent. Each of these
-build steps is defined as a function (task), usually with a "do\_" prefix
-(e.g. :ref:`ref-tasks-fetch`,
-:ref:`ref-tasks-unpack`, and so
-forth). These functions are typically shell scripts but can instead be
-written in Python.
-If you look at the contents of a recipe, you will see that the recipe
-does not include complete instructions for building the software.
-Instead, common functionality is encapsulated in classes inherited with
-the ``inherit`` directive. This technique leaves the recipe to describe
-just the things that are specific to the software being built. There is
-a :ref:`ref-classes-base` class that is implicitly inherited by all recipes
-and provides the functionality that most recipes typically need.
-The remainder of this section presents information useful when working
-with recipes.
-Finding Logs and Work Files
---------------------------
-After the first run of the ``devtool build`` command, recipes that were
-previously created using the ``devtool add`` command or whose sources
-were modified using the ``devtool modify`` command contain symbolic
-links created within the source tree:
-  ``oe-logs``: This link points to the directory in which log files and
-   run scripts for each build step are created.
-  ``oe-workdir``: This link points to the temporary work area for the
-   recipe. The following locations under ``oe-workdir`` are particularly
-   useful:
-   -  ``image/``: Contains all of the files installed during the
-      :ref:`ref-tasks-install` stage.
-      Within a recipe, this directory is referred to by the expression
-      ``${``\ :term:`D`\ ``}``.
-   -  ``sysroot-destdir/``: Contains a subset of files installed within
-      :ref:`ref-tasks-install` that have been put into the shared sysroot. For
-      more information, see the
-      ":ref:`dev-manual/new-recipe:sharing files between recipes`" section.
-   -  ``packages-split/``: Contains subdirectories for each package
-      produced by the recipe. For more information, see the
-      ":ref:`sdk-manual/extensible:packaging`" section.
-You can use these links to get more information on what is happening at
-each build step.
-Setting Configure Arguments
---------------------------
-If the software your recipe is building uses GNU autoconf, then a fixed
-set of arguments is passed to it to enable cross-compilation plus any
-extras specified by :term:`EXTRA_OECONF` or :term:`PACKAGECONFIG_CONFARGS`
-set within the recipe. If you wish to pass additional options, add them
-to :term:`EXTRA_OECONF` or :term:`PACKAGECONFIG_CONFARGS`. Other supported build
-tools have similar variables (e.g.  :term:`EXTRA_OECMAKE` for CMake,
-:term:`EXTRA_OESCONS` for Scons, and so forth). If you need to pass anything on
-the ``make`` command line, you can use :term:`EXTRA_OEMAKE` or the
-:term:`PACKAGECONFIG_CONFARGS` variables to do so.
-You can use the ``devtool configure-help`` command to help you set the
-arguments listed in the previous paragraph. The command determines the
-exact options being passed, and shows them to you along with any custom
-arguments specified through :term:`EXTRA_OECONF` or
-:term:`PACKAGECONFIG_CONFARGS`. If applicable, the command also shows you
-the output of the configure script's "--help" option as a
-reference.
-Sharing Files Between Recipes
-----------------------------
-Recipes often need to use files provided by other recipes on the
-:term:`Build Host`. For example,
-an application linking to a common library needs access to the library
-itself and its associated headers. The way this access is accomplished
-within the extensible SDK is through the sysroot. There is one sysroot per
-"machine" for which the SDK is being built. In practical terms, this
-means there is a sysroot for the target machine, and a sysroot for
-the build host.
-Recipes should never write files directly into the sysroot. Instead,
-files should be installed into standard locations during the
-:ref:`ref-tasks-install` task within the ``${``\ :term:`D`\ ``}`` directory. A
-subset of these files automatically goes into the sysroot. The reason
-for this limitation is that almost all files that go into the sysroot
-are cataloged in manifests in order to ensure they can be removed later
-when a recipe is modified or removed. Thus, the sysroot is able to
-remain free from stale files.
-Packaging
---------
-Packaging is not always particularly relevant within the extensible SDK.
-However, if you examine how build output gets into the final image on
-the target device, it is important to understand packaging because the
-contents of the image are expressed in terms of packages and not
-recipes.
-During the :ref:`ref-tasks-package` task, files installed during the
-:ref:`ref-tasks-install` task are split into one main package, which is almost
-always named the same as the recipe, and into several other packages. This
-separation exists because not all of those installed files are useful in every
-image. For example, you probably do not need any of the documentation installed
-in a production image. Consequently, for each recipe the documentation
-files are separated into a ``-doc`` package. Recipes that package
-software containing optional modules or plugins might undergo additional
-package splitting as well.
-After building a recipe, you can see where files have gone by looking in
-the ``oe-workdir/packages-split`` directory, which contains a
-subdirectory for each package. Apart from some advanced cases, the
-:term:`PACKAGES` and :term:`FILES` variables controls
-splitting. The :term:`PACKAGES` variable lists all of the packages to be
-produced, while the :term:`FILES` variable specifies which files to include
-in each package by using an override to specify the package. For
-example, ``FILES:${PN}`` specifies the files to go into the main package
-(i.e. the main package has the same name as the recipe and
-``${``\ :term:`PN`\ ``}`` evaluates to the
-recipe name). The order of the :term:`PACKAGES` value is significant. For
-each installed file, the first package whose :term:`FILES` value matches the
-file is the package into which the file goes. Both the :term:`PACKAGES` and
-:term:`FILES` variables have default values. Consequently, you might find
-you do not even need to set these variables in your recipe unless the
-software the recipe is building installs files into non-standard
-locations.
-Restoring the Target Device to its Original State
-=================================================
-If you use the ``devtool deploy-target`` command to write a recipe's
-build output to the target, and you are working on an existing component
-of the system, then you might find yourself in a situation where you
-need to restore the original files that existed prior to running the
-``devtool deploy-target`` command. Because the ``devtool deploy-target``
-command backs up any files it overwrites, you can use the
-``devtool undeploy-target`` command to restore those files and remove
-any other files the recipe deployed. Consider the following example::
-   $ devtool undeploy-target lighttpd root@192.168.7.2
-If you have deployed
-multiple applications, you can remove them all using the "-a" option
-thus restoring the target device to its original state::
-   $ devtool undeploy-target -a root@192.168.7.2
-Information about files deployed to
-the target as well as any backed up files are stored on the target
-itself. This storage, of course, requires some additional space on the
-target machine.
-.. note::
-   The ``devtool deploy-target`` and ``devtool undeploy-target`` commands do
-   not currently interact with any package management system on the target
-   device (e.g. RPM or OPKG). Consequently, you should not intermingle
-   ``devtool deploy-target`` and package manager operations on the target
-   device. Doing so could result in a conflicting set of files.
