Chromium Build Failing on Windows

[Paras HS]

I've built the Chromium browser on my Windows from its official source code by following this documentation.

I made some changes and executed my first build and ran into some errors.

I have tried cleaning and rebuilding, but still couldn't get rid of these errors.
How can I get rid of them?

Any help would be appreciated!
