The Yocto Project builds embedded Linux packages from source using BitBake tasks executing a deterministic sequence of recipe compilation stages.

BitBake Task Pipeline Sequence

1. do_fetch: Downloads source tarballs or clones git repositories. 2. do_unpack & do_patch: Extracts code to ${S} and applies patch files. 3. do_configure & do_compile: Runs cmake/make toolchains. 4. do_install: Installs artifacts to image sysroot ${D}.
