Thanks for filing the issue!

As this issue seems to be related to build which is out of scope for ET team to triage, hence adding label TE-NeedsTriageHelp for further investigation.

On Linux a number of compile errors are generated, such as:

Changing status to assigned, since the issue has an owner.

some undefined-symbol link errors occurred after add includes to //chrome/browser/BUILD.gn

 Issue 809971  has been merged into this issue.

I've implemented a bot that looks for this:

Do we actually have a commitment from somebody to fix this?

I don't think we can fix this properly without a clear definition of what this flag should do, is there such a definition?

Well, there should be no dependency on //third_party/webrtc I suppose.

That will be more and more complex to maintain imo, since more and more dependencies are coming from other APIs than PeerConnection (chromoting, AEC in audio process etc). Is there still a reason for excluding this dependency?

All right, then I guess we should remove enable_webrtc altogether.

The following revision refers to this bug:
  https://chromium.googlesource.com/chromium/src.git/+/c6d201bf57dab8c8c53470325bbe19deca1523f4

commit c6d201bf57dab8c8c53470325bbe19deca1523f4
Author: Wez <wez@chromium.org>
Date: Thu May 03 17:04:59 2018

Remove |enable_webrtc| exception for Cast Audio builds.

- Remove |enable_webrtc=false| from the Cast Audio bot configuration.
- Set |enable_webrtc=true| by default, rather than based on whether
  |is_cast_audio_only| is set.

This requires a roll of OpenH264 to pick up changes that fix it not to
use pthreads APIs that are not present under Fuchsia.

CL that removes enable_webrtc: https://chromium-review.googlesource.com/c/chromium/src/+/1044220

I'll dry run it and then find reviewers.

Ok, done and reviewed, it's going in now...

commit d98b020fe1f0cb85de21de5313261a66ad9c9fe4

Remove enable_webrtc and treat it as always true from now on.

enable_webrtc=false has been broken for months and no one has noticed,
so let's get rid of this complexity. WebRTC will now be a part of
Chromium until the serpent Nidhoggr ascends into the sky and ushers
in Ragnarök.

Next step: remove #ifdef'd code that depends on defines that
were set by enable_webrtc.

Removed BUILDFLAG(ENABLE_WEBRTC).

The enable_webrtc gn variable has been removed, so ENABLE_WEBRTC is
always true now; we may as well remove it.
