gn.py: Could not find gn executable at: F:\code\chromium_git\chromium\src\buildt ools\win\gn.exe

[gen]

1, I am trying to generate sln and build the CEF/Chromium under Windows, but I got the error below. 

gn.py: Could not find gn executable at: F:\code\chromium_git\chromium\src\buildt ools\win\gn.exe

2, I have run the below command correctly.

F:\code\depot_tools>python.bat gsutil.py config

3, I used the below command to debug, but it still failed.

How can I get the gn.exe? 

[Brett Wilson]

You'll have to ask CEF people. This list is for Chromium development and we don't know how their checkout works.

Thanks Brett.

The CEF uses the chromium checkout flow. 

I also followed the steps in http://dev.chromium.org/developers/how-tos/get-the-code. when i run

gclient runhooks

I got the error same. 

Because the gn.exe doesn't exist under chromium source directory, I can't find a exactly working flow to get the gn.exe.

You should run gclient runhooks to download this gn.exe

In fact, this error is triggered by 'gclient runhooks'. 

I have checked the script source code. It failed in get_toolchain_if_necessary.py.

Seems that the user should pass the below check. Do you know how to access the ToolchainBucket as a external user?

  if desired_hash not in current_hashes:

    should_use_gs = False

    if (HaveSrcInternalAccess() or

        LooksLikeGoogler() or

        CanAccessToolchainBucket()):

      should_use_gs = True

      if not CanAccessToolchainBucket():

        RequestGsAuthentication()

You need to actually read the page you linked to for Windows https://chromium.googlesource.com/chromium/src/+/master/docs/windows_build_instructions.md in particular the "Open source contributors".
