Can not generate the project file

[Bicen Zhu]

Hi *,

I was trying to build chromium following the guide: https://chromium.googlesource.com/chromium/src/+/master/docs/windows_build_instructions.md

Visual Studio Community 2017 was installed with the suggesting commond arguments: 

--add Microsoft.VisualStudio.Workload.NativeDesktop
    --add Microsoft.VisualStudio.Component.VC.ATLMFC --includeRecommended

And I also installed the "Debuging Tools for Windows" as suggested in the guide.

Chromium code was fetched and synced perfectly

but when running following command:

gn gen --ide=vs out\Default

Errors occured(after re-syncing(by gclient sync) it has the simillar phenomenon)

E:\chromium\src>gclient sync

Syncing projects: 100% (83/83), done.

Running hooks: 100% (60/60), done.

E:\chromium\src>gn gen --ide=vs out\Default

actally i also tried "gn gen out/Default", it has the similar problem, but not exactly same.

Could anyone help?

Thanks!

I have the exact same problem. Have you been able to solve it?

\"/Ic:\\program files (x86)\\microsoft visual studio\\2017\\community\\vc\\tools\\msvc\\14.13.26128\\include\"

The problem is it is expecting SDK 10.0.15063.0 , but actually it was not installed

After install the SDK, problem disappear

The SDK can be found here: https://developer.microsoft.com/en-us/windows/downloads/sdk-archive

[André Kamara]

It did the trick. Thanks a lot.

BTW, the reason that we insist on using the 10.0.15063.0 version of the SDK is that 10.0.16299.0 (Fall Creators Update) has some bugs which make it incompatible with clang-cl. We are hopeful that the next Windows 10 SDK will work with clang. Initial pre-release testing is promising.
