Part of the downloaded AGL software is a setup script that you must run to initialize the build environment.
You can find this script here:
The script accepts many options that allow you to define build parameters such as the target hardware (i.e. the machine), build directory, and so forth. Use the following commands to see the available options and script syntax:
$ cd $AGL_TOP/pike $ source meta-agl/scripts/aglsetup.sh -h
AGL Machines (board support)
Your target platform will be selected with the
The MACHINE can be selected from the templates in
Note: This is also the place where you can add new boards.

Before running the
aglsetup.sh, you should understand what AGL features you
want to include as part of your image.
The script's help output lists available features and shows you the layers in
which they reside.
Following is a list of the available features:
Available features: [meta-agl] # CORE layer Refer: https://git.automotivelinux.org/AGL/meta-agl/tree/templates/feature agl-all-features # For the usual demo image agl-app-framework # Application Framework agl-archiver # Source Archiver agl-buildstats # Build Statistics agl-ci-change-features-nogfx # CI: features enabled for gerrit change builds w/o gfx agl-ci-change-features # CI: features enabled for gerrit change builds with gfx agl-ci-snapshot-features-nogfx # CI: features enabled for nightly builds w/o gfx agl-ci-snapshot-features # CI: features enabled for nightly builds with gfx agl-ci # CI: specific settings for the CI environment agl-create-spdx # Software Bill of Materials (SBOM) generation agl-devel :( agl-package-management ) # Developer Env (root login w/o pass) agl-fossdriver # Fossology integration, Scancode, etc. agl-localdev # inclusion of local development folder ./meta-localdev agl-netboot # network boot (e.g. in CI) agl-package-management # include package management (e.g. rpm) agl-pipewire # include pipewire agl-ptest # enable ptest pckages agl-refhw-h3 # enable reference hardware when building h3ulcb machine agl-selinux # Enables building with SELinux agl-virt # EG-Virt features agl-virt-guest-xen # EG-Virt features agl-virt-xen # EG-Virt features agl-weston-remoting # remote streaming support agl-weston-waltham-remoting # remote streaming support w/ waltham [meta-agl-demo] # DEMO layer Refer: https://git.automotivelinux.org/AGL/meta-agl-demo/tree/templates/feature agl-demo-cluster-support # Add streaming to cluster of AGL demo system agl-demo-preload # Add Tokens and sample files specific to AGL demo system agl-demo # default IVI demo agl-kvm # Enables support for building multiconfig based KVM+QEMU demo images [meta-agl-devel] # Development layer Refer: https://git.automotivelinux.org/AGL/meta-agl-devel/tree/templates/feature agl-basesystem # Toyota basesystem agl-drm-lease # DRM lease support agl-egvirt # EG-Virt feature agl-flutter # Flutter support agl-ic-container # Instrument Cluster EG demo using containers agl-jailhouse # GSoC: jailhouse enablement agl-offline-voice-agent # Feature template for meta-offline-voice-agent layer agl-test # Test framework under development

An AGL feature is a configuration that accounts for specific settings
and dependencies needed for a particular build.
For example, specifying the "agl-demo" feature makes sure that the
aglsetup.sh script creates configuration files needed to build the
image for the AGL demo.
Following are brief descriptions of the AGL features you can specify on the
aglsetup.sh command line:
agl-all-features: A set of AGL default features. Do not think of this set of features as all the AGL features.
agl-app-framework: Application Framework
agl-archiver: Enables the archiver class for releases.
agl-ci: Flags used for Continuous Integration (CI). Using this feature changes the value of the
agl-ci-change-features: Enables features for CI builds for Gerrit changes.
agl-ci-change-features-nogfx: Enables features for CI builds for Gerrit changes for targets that use binary graphics drivers (i.e. builds without graphics).
agl-ci-snapshot-features: Enables features for CI daily snapshot builds.
agl-ci-snapshot-features-nogfx: Enables features for CI daily snapshot builds for targets that use binary graphics drivers (i.e. builds without graphics).
agl-devel: Activates development options such as an empty root password, debuggers, strace, valgrind, and so forth.
agl-netboot: Enables network boot support through Trivial File Transfer Protocol (TFTP) and Network Block Device (NBD) protocol. Netboot is needed for CI and useful for development to avoid writing sdcards. Needs additional setup.
agl-ptest: Enables Ptest as part of the build.
agl-demo: Enables the layers meta-agl-demo and meta-qt5. You need agl-demo if you are going to build the agl-demo-platform.
agl-pipewire: Enables AGLs pipewire support.
agl-localdev: Adds a local layer named "meta-localdev" in the meta directory and a local.dev.inc configuration file when that file is present.
This feature provides a shortcut for using the layer meta-localdev in the top-level folder for easy modifications to your own recipes.
Following is an example that initializes the build environment, selects "beaglebone" for the machine, and chooses the "agl-demo" feature, which also includes the "agl-appfw-smack", "agl-devel", and "agl-hmi-framework" features:
$ source meta-agl/scripts/aglsetup.sh -m qemux86-64 -b qemux86-64 agl-demo agl-devel aglsetup.sh: Starting Generating configuration files: Build dir: /home/scottrif/workspace_agl/build Machine: qemux86-64 Features: agl-appfw-smack agl-demo agl-devel Running /home/scottrif/workspace_agl/poky/oe-init-build-env Templates dir: /home/scottrif/workspace_agl/meta-agl/templates/base Config: /home/scottrif/workspace_agl/build/conf/bblayers.conf Config: /home/scottrif/workspace_agl/build/conf/local.conf Setup script: /home/scottrif/workspace_agl/build/conf/setup.sh Executing setup script ... --- beginning of setup script fragment /home/scottrif/workspace_agl/meta-agl/templates/base/01_setup_EULAfunc.sh fragment /home/scottrif/workspace_agl/meta-agl/templates/base/99_setup_EULAconf.sh end of setup script OK Generating setup file: /home/scottrif/workspace_agl/build/agl-init-build-env ...

You can now run 'bitbake target' Common targets are: - meta-agl: (core system) agl-image-minimal agl-image-minimal-qa agl-image-ivi agl-image-ivi-qa agl-image-ivi-crosssdk agl-image-weston - meta-agl-demo: (demo with UI) agl-demo-platform (* default demo target) agl-demo-platform-qa agl-demo-platform-crosssdk agl-demo-platform-html5
Running the script creates the Build Directory if it does not already exist.
The default Build Directory is
$AGL_TOP/<release-branch-name>/build, and the nomenclature to be used throughout this doc is going to be
For this example, the Build Directory is
The script's output also indicates the machine and AGL features selected for the build.
The script creates two primary configuration files used for the build:
Both these configuration files are located in the Build Directory in the
If you were to examine these files, you would find standard Yocto Project
configurations along with AGL configuration fragments, which are driven by the
machine (i.e. beaglebone) and the AGL features specified as part of the
script's command line.
The end result is configuration files specific for your build in the AGL development environment.
Finally, part of the
aglsetup.sh script makes sure that any End User License Agreements (EULA)
You can see that processing in the script's output as well.
NOTE: Use of the
bblayers.conf configuration files is fundamental
in the Yocto Project build environment.
Consequently, it is fundamental in the AGL build environment.
You can find lots of information on configuring builds in the Yocto Project
