api-ms-win-downlevel-kernel32-l2-1-0.dll NOT there

[awarnick]

I'm attempting to build the latest master. I keep getting this error:

Exception: api-ms-win-downlevel-kernel32-l2-1-0.dll not found in "C:\Program Files (x86)\Windows Kits\10\Debuggers\x86\api-ms-win-downlevel-kernel32-l2-1-0.dll"
You must install the "Debugging Tools for Windows" feature from the Windows 10 SDK, the 10.0.19041.0 version.

Indeed, api-ms-win-downlevel-kernel32-l2-1-0.dll is not there, but the Windows 10 SDK 19041 (Visual Studio 2019 feature) is installed. I've tried doing a repair and rebooting, but the dll still isn't there. Maybe the solution is to stop trusting Visual Studio to install the SDK?

Maybe the solution is to stop trusting Visual Studio to install the SDK?

That's probably correct. I always install the SDK using the separate Windows SDK installer.

[awarnick]

Confirmed. That was the issue. So sad, really.

The build worked, but the network service crashes when trying to go to certain pages, such as the Accelerated 2D Canvas test.

Run with:
cefclient.exe --disable-gpu --no-sandbox

[magreenblatt]

the network service crashes when trying to go to certain pages, such as the Accelerated 2D Canvas test.

Looks like a crash in Chromium. Does it reproduce in the release branches?

[awarnick]

It's a DCHECK. I just commented it out, for now, and it works fine (or seems to). I'll try an official release build from the site.

Then I had to do this one in content_security_policy.cc (line 705):
void Deprecation::GenerateReport(const LocalFrame* frame, WebFeature feature) {
if (!frame || !frame->Client())
return;

const DeprecationInfo info = GetDeprecationInfo(feature);
if(info.message.IsEmpty()) return; // *** I put this line here ***

// Send the deprecation message to the console as a warning.
//DCHECK(!info.message.IsEmpty());

Then this one in services/audio:
[0807/143203.986:FATAL:service.cc(136)] Check failed: enable_remote_client_support_.
That could be happening because I don't have a mic.

I'm starting to think that my build is corrupt or something, but I don't know how that's possible.

[awarnick]

Then this one when I exited (renderer_process_host_impl.cc (line 1691)):
#ifndef NDEBUG
DCHECK(is_self_deleted_)
<< "RenderProcessHostImpl is destroyed by something other than itself";
#endif

[awarnick]

The latest release build is fine.
