+2.1.1. Build Overview

+ The first thing you need to do is set up the OpenEmbedded build environment by sourcing + the environment setup script as follows: +

+     $ source oe-init-build-env [build_dir]
+

+ The build_dir is optional and specifies the directory the + OpenEmbedded build system uses for the build - + the Build Directory. + If you do not specify a Build Directory it defaults to build + in your current working directory. + A common practice is to use a different Build Directory for different targets. + For example, ~/build/x86 for a qemux86 + target, and ~/build/arm for a qemuarm target. + See oe-init-build-env + for more information on this script. +

+ Once the build environment is set up, you can build a target using: +

+     $ bitbake <target>
+

+ The target is the name of the recipe you want to build. + Common targets are the images in meta/recipes-core/images, + /meta/recipes-sato/images, etc. all found in the + Source Directory. + Or, the target can be the name of a recipe for a specific piece of software such as + busybox. + For more details about the images the OpenEmbedded build system supports, see the + "Images" chapter. +

Note

+ Building an image without GNU General Public License Version 3 (GPLv3) components + is only supported for minimal and base images. + See the "Images" chapter for more information. +
