The following subsections provide lists of variables whose context is configuration: distribution, machine, and local.

This section lists variables whose context is the distribution, or distro. DISTRO DISTRO_NAME DISTRO_VERSION MAINTAINER PACKAGE_CLASSES TARGET_OS TARGET_FPU TCMODE TCLIBC

This section lists variables whose context is the machine. TARGET_ARCH SERIAL_CONSOLE PACKAGE_EXTRA_ARCHS IMAGE_FSTYPES MACHINE_FEATURES MACHINE_EXTRA_RDEPENDS MACHINE_EXTRA_RRECOMMENDS MACHINE_ESSENTIAL_EXTRA_RDEPENDS MACHINE_ESSENTIAL_EXTRA_RRECOMMENDS

This section lists variables whose context is the local configuration through the local.conf file. DISTRO MACHINE DL_DIR BBFILES EXTRA_IMAGE_FEATURES PACKAGE_CLASSES BB_NUMBER_THREADS BBINCLUDELOGS ENABLE_BINARY_LOCALE_GENERATION

The following subsections provide lists of variables whose context is recipes: required, dependencies, path, and extra build information.
