<div>Note: I already sent this email, but I didn’t get any
answer, nor can I see the thread in the archives. Therefore
I think it was blocked, maybe because of the attachment that
I remove this time.</div>
<div><br>
</div>
<div>I’m new on this mailing so I’ll start by introducing
myself:</div>
<div>My name Jacques-Olivier Haché (J-O), I’m working for
Temasys Communication, and I’m entering the WebKit project
to work on the implementation of WebRTC inside WebKit.</div>
<div>For those who would be following the WebRTC’s news, I’m
also the main developer of the WebRTC plugin released by
Temasys.</div>
<div><br>
</div>
<div>Back to business:</div>
<div><br>
</div>
<div>I was able to download the project, build it and run it
inside Safari. I did not try to run it in a different
browser yet.</div>
<div><br>
</div>
<div>My configuration:</div>
<div>
<ul>
<li>Macbook Air 2012</li>
<li>Mac OS X 10.9.4</li>
<li>Revision 171167</li>
<li>I’m on master</li>
<li>I suppose I’m using the regular Mac port as I didn’t
see where to change from one port to another yet.</li>
<li>building for debug mode</li>
</ul>
</div>
<div>I am now trying to enable the WebRTC related features to
get a better understanding of the current state of this part
of the project. </div>
<div>I have to say that I faced a lack of documentation on
this area. I found the <a moz-do-not-send="true" href="https://trac.webkit.org/wiki/FeatureFlags">features
list</a>, a document about <a moz-do-not-send="true" href="https://trac.webkit.org/wiki/AddingFeatures">how to
add a new feature</a> but nothing about how to turn a
feature on and off (there is actually a TODO about that in
the second link).</div>
<div><br>
</div>
<div>I looked into the files that one needs to change to add a
new feature and found two interesting files:</div>
<div>
<ul>
<li><span style="background-color: rgb(255, 255, 255);">Source/WTF/wtf/FeatureDefines.h
- where the WebRTC related contants were set to
0 instead of 1</span></li>
<li>Source/cmake/WebKitFeatures.cmake - where the contants
were set to OFF</li>
</ul>
</div>
<div>I listed the following definitions that look related to
WebRTC</div>
<div>
<ul>
<li>ENABLE_MEDIA_CAPTURE</li>
<li>ENABLE_MEDIA_CONTROLS_SCRIPT</li>
<li>ENABLE_MEDIA_SOURCE</li>
<li>ENABLE_MEDIA_STATISTICS</li>
<li>ENABLE_MEDIA_STREAM</li>
<li>ENABLE_VIDEO</li>
<li>ENABLE_VIDEO_TRACK</li>
</ul>
</div>
<div>I turned those definitions to 1 and ON in the respective
file and tried to build.</div>
<div>The code in the header
WebCore/Modules/mediastream/mediastream.h could not compile
apparently because the observer did not have a destructor. I
created one:</div>
<div>
<div> class Observer {</div>
<div> public:</div>
<div> virtual void didAddOrRemoveTrack() = 0;</div>
<div> virtual ~Observer() {};</div>
<div> };</div>
</div>
<div><br>
</div>
<div>and tried to build again.<br>
<br>
</div>
<div>I now have a linking error when building WebCore with
Xcode. </div>
<div><br>
</div>

The first error could simply be because the files defining those
symbols are not included in the XCode project file. Nobody has
worked on WebRTC for a while, it probably only builds for GTK.<br>
<br>
The second error is likely a problem with the incremental build. I
would just delete WebKitBuild and start a clean build.<br>

Yep, that's weird. I only run into problems with precompiled headers
when I change my SDK.<br>
But after changing feature flags you often have to do a clean build
anyway. There are too many code generators that are not tracking
these kind of dependencies.<br>
<br>
Good luck!<br>
