From 685bb88433b7520946e30a1e520d37bfc2288151 Mon Sep 17 00:00:00 2001 From: dsinclair Date: Wed, 20 Apr 2016 07:32:39 -0700 Subject: Standalone GN build. This CL setups up a standalone GN build. You'll need to set gn args similar to: use_goma = true clang_use_chrome_plugins = false pdf_enable_xfa = true pdf_enable_v8 = true pdf_is_standalone = true The third_party/pymock files are needed to make git cl upload work correctly.

V8 defines a top-level +target, //v8:d8 (a simple executable), which will only be built in the +standalone configuration. To indiate itis a standalone configuration, v8 can +create a file, build_overrides/v8.gni, containing a variable, +`build_standalone_d8 = true` and import it (as +import("//build_overrides/v8.gni") from its top-level BUILD.gn file. + +Chromium, on the other hand, does not need to build d8, and so it would +create its own build_overrides/v8.gni file, and in it set +`build_standalone_d8 = false`. + +The two files should define the same set of variables, but the values may +vary as appropriate to suit the the needs of the two different builds. + +The build.gni file provides a way for projects to override defaults for +variables used in //build itself (which we want to be shareable between +projects). + +TODO(crbug.com/588513): Ideally //build_overrides and, in particular, +//build_overrides/build.gni will go away completely in favor of some +mechanism that can re-use other required files like //.gn, so that we don't +have to keep requiring projects to create a bunch of different files to use GN. diff --git a/build_overrides/build.gni b/build_overrides/build.gni new file mode 100644 index 0000000000..fe286e5fcf --- /dev/null +++ b/build_overrides/build.gni @@ -0,0 +1,9 @@ +# Copyright 2016 The Chromium Authors.
