MB - The Meta-Build wrapper
MB is a simple wrapper intended to provide a uniform interface to either GYP or GN, such that users and bots can call one script and not need to worry about whether a given bot is meant to use GN or GYP.
It supports two main functions:
-
"gen" - the main
gyp_chromium/gn geninvocation that generates the Ninja files needed for the build. -
"analyze" - the step that takes a list of modified files and a list of desired targets and reports which targets will need to be rebuilt.
We also use MB as a forcing function to collect all of the different
build configurations that we actually support for Chromium builds into
one place, in //tools/mb/mb_config.pyl.
