7.1.1. bitbake/

This directory includes a copy of BitBake for ease of use. The copy usually matches the current stable BitBake release from the BitBake project. BitBake, a Metadata interpreter, reads the Yocto Project Metadata and runs the tasks defined by that data. Failures are usually from the Metadata and not from BitBake itself. Consequently, most users do not need to worry about BitBake.

When you run the bitbake command, the main BitBake executable, which resides in the bitbake/bin/ directory, starts. Sourcing an environment setup script (e.g. oe-init-build-env or oe-init-build-env-memres) places the scripts and bitbake/bin directories (in that order) into the shell's PATH environment variable.

For more information on BitBake, see the BitBake User Manual.
