Chromium build on windows is not going through

[Ravikumar Patil]

Chromium build on windows is not working. I am trying to build latest chromium source on windows 7 for last one week am getting following error

[887/29625] CXX obj/components/crash/content/app/run_as_crashpad_handler/fallback_crash_handler_win.obj

ninja: build stopped: subcommand failed.

If I replace PROCESSOR_ARCHITECTURE_ARM32_ON_WIN64 with value 13 in the respective header, I am getting undefined identifier errors for some other parameters in some other files. How to fix these errors and get the Chromium build working on windows machine.

Do you have the correct Windows SDK version installed? See the Windows build instructions here: https://chromium.googlesource.com/chromium/src/+/master/docs/windows_build_instructions.md

Can you also paste the contents of args.gn file in the output directory?

Sunny is correct. You do not have the 10.0.14393 SDK installed. You can see from this page that PROCESSOR_ARCHITECTURE_ARM32_ON_WIN64 was newly added in 10.014393:

https://abi-laboratory.pro/compatibility/Windows_10_1511_10586.494_to_Windows_10_1607_14393.0/x86_64/headers_diff/ntdll.dll/diff.html

I have not found an effective way to detect at compile time what version of the SDK is installed which is why we don't have better error messages. We do, at least, detect if you don't have a new enough version of the compiler installed.

Thank you Sunny and Bruce...

I remember I followed the steps from the link  https://chromium.googlesource.com/chromium/src/+/master/docs/windows_build_instructions.md to install required SDK some time back last year and I was able to build old chromium source (in December 2016).

Now with latest source I am getting these errors. And I am not using any args parameters.

Do I need to try installing these SDKs again?

Thanks

Yes.

Chromium switched to requiring the 14393 SDK late last year. Maybe you built before we required 14393. Some things to check include do you have this directory:

    "c:\Program Files (x86)\Windows Kits\10\Include\10.0.14393.0"

If not then install the 14393 SDK. Tracking down the 14393.0 SDK could be tricky right now because Microsoft just released the 15063 SDK, and there are some build errors with that which I am investigating.

You can also try running these two commands from a fresh command prompt, for diagnostic purposes:

    > "%VS140COMNTOOLS%..\..\VC\vcvarsall.bat" amd64 10.0.14393.0

    > set include

The first one sets up the VC/SDK environment variables and the second one prints the include variable. The first command will fail if the needed SDK is not installed. If it fails then run it again without the 10.0.14393.0 parameter. The second one lets you determine which SDK version you are getting. Look at these results and then do further investigations on your end.

When build\toolchain\win\setup_toolchain.py script runs vcvarsall.bat it specifies amd64 but does not specify the SDK version. This appears to mean that you will get the latest SDK version (I get 15063 because I just installed that yesterday).

Hi Bruce,

I reinstalled the visual studio 15 and sdk 14393. And I selected as mentioned in Setting up Windows

• Visual C++, which will select three sub-categories including MFC
• Universal Windows Apps Development Tools > Tools (1.4.1) and Windows 10 SDK (10.0.14393)
• 
  

Following are the outputs on my machine.

C:\Project\Chromium\Source\src>"%VS140COMNTOOLS%..\..\VC\vcvarsall.bat" amd64 10.0.14393.0

!ERROR! Windows SDK 10.0.14393.0 : 'C:\Program Files (x86)\Windows Kits\10\include\10.0.14393.0\um'

I dont see folder "C:\Program Files (x86)\Windows Kits\10\include\10.0.14393.0". Could you please guide me to link to use for installing visual studio 15 with sdk 14393?

Thanks

What do you see in this directory?

    "C:\Program Files (x86)\Windows Kits\10\include"

My best guess is that you installed the latest SDK, which is 15063. Due to a bug in Bits.h Chrome can't build with that SDK unless you patch it. That is why we recommend the 14393 SDK. So, you should probably install the 14393 SDK. The Windows 10 SDK install page here: https://developer.microsoft.com/en-us/windows/downloads/windows-10-sdk

contains a link to an archive page here: https://developer.microsoft.com/en-us/windows/downloads/sdk-archive

That in turn has a link to a download of the 10.0.14393.795 SDK. That should work.

It is unfortunate that Microsoft has complicated this process by releasing a new (default) SDK that is broken. You can track that issue here:

https://developercommunity.visualstudio.com/content/problem/42961/15063-sdk-is-broken-bitsh-indirectly-references-no.html

I haven't seen an ETA on when they will fix it.

Hi Bruce,

After installing SDK from the link you mentioned below, I am able to build chromium source on windows 7.

I had visual studio 2015 (not the latest one), but sdk 14393.715 was missing. After installing SDK I am able to build chromium source.

Thanks
