BitBake

BitBake is a tool for building software libraries/applications using recipes such as those provided by meta-openembedded.

• Consumes recipes to create binaries.
• Co-maintained by Yocto and OpenEmbedded.
• Both Yocto and OpenEmbedded maintain collections of open source BitBake layers and recipes that describe how to build and deploy software components.
• Recipes are text-based configuration files that describe how a software library or application should be built.
• Recipes define:
  • Location of source code.
  • Source code patches (optional).
  • Custom built settings (optional).
• Recipes are grouped into layers.
• Recipes in upper layers can augment or override layers below.
• Edge OS uses Yocto’s Poky reference Linux Distribution and extends it using OpenEmbedded layers such as _meta-python_ and meta-oe.
  • See Poky for more information.
