BitBake is a task execution engine build automation tool that allows shell and Python tasks to run in parallel yet in order constrained by configured dependencies.
Engine
[edit]It was originally developed for and is commonly used to build embedded Linux distributions – often using a cross compiler to target a system that differs architecturally from the build host.
BitBake provides capabilities similar to make but via significantly different configuration information. A BitBake recipe specifies how to build a package with information such as where to pull source code from (source URL), dependency constraints, and compile and install options. A source URL commonly specifies a git repo, but other protocols are supported including: http, https, ftp, cvs, svn, and local file system. A recipe also stores metadata for a package in standard variables.[3]
During a build operation, recipes determine build order (constrained by dependencies) and processing tasks to be performed to produce the requested target – recipe or package. A relatively high-level target can produce a complete system software image consisting of boot-time resources, a kernel and a root file system. A build typically includes building the cross-platform build toolchain that generates code for the target platform.
BitBake was inspired by Portage,[4] which is the package management system used by the Gentoo Linux distribution. BitBake existed for some time in the OpenEmbedded project until it was separated out into a standalone, maintained, distribution-independent tool. BitBake is co-maintained by the Yocto Project and the OpenEmbedded project.
