Needs additional setup. + +* **agl-ptest**: Enables + [Ptest](https://yoctoproject.org/docs/3.1.4/dev-manual/dev-manual.html#testing-packages-with-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. + +## Example + +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: + +```sh +$ 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 ...
