An error when building chromiun on windows (gn gen <dir>)

[Ben Amsalem]

I follow the guidelines in https://chromium.googlesource.com/chromium/src/+/master/docs/windows_build_instructions.md

When I run `gn gen out/Default` I get an unexpected error:

ERROR at //components/nacl/features.gni:6:1: Can't load input file.

import("//build/config/gclient_args.gni")

^---------------------------------------

Unable to load:

  D:/chromium/src/build/config/gclient_args.gni

I also checked in the secondary tree for:

  D:/chromium/src/build/secondary/build/config/gclient_args.gni

See //BUILD.gn:15:1: whence it was imported.

import("//components/nacl/features.gni")

^--------------------------------------

* it used to work for me on the same computer in the past, I'm afraid the chromium code has changed while depot_tools still expect an old file(s).

Anyone can help?

I landed a change last week that started using this file, which is supposed to be generated by gclient when `gclient sync` is run.

Make sure that your depot_tools checkout is up-to-date, and that `gclient sync` is running successfully to completion. If you're

pretty sure that they both are, and you're still seeing the problem, please file a bug and cc' me and we can follow up there.

maybe your source code is incomplete.

you can use "gclient sync --force" and try again.
