Since this directory is DEPS'ed in by some other repositories (webrtc, pdfium, v8, etc), it should be kept as self-contained as possible by not referring to files outside of it. Some exceptions exist (
//third_party subdirectories), but new dependencies tend to break these other projects, and so should be avoided.
Changes to //build should be landed in the Chromium repo. They will then be replicated to the stand-alone build repo by the gsubtreed tool.
//build/config- Common templates via
//build/toolchain- GN toolchain definitions.
Other .py files- Some are used by GN/Ninja. Some by gclient hooks, some are just random utilities.
Files referenced by
//build/BUILDCONFIG.gn- Included by all
//build/secondary- An overlay for
BUILD.gnfiles. Enables adding
BUILD.gnto directories that live in sub-repositories.
//build_overrides- Refer to //build_overrides/README.md.
