<div>I just deleted the XCodeBuild folder and added a couple of
files in the project manually. </div>
<div>My computer is re-building the project, I will see how it
goes.</div>
<div>A couple of extra questions:</div>
<div><br>
</div>
<div>1) After deleting the XCodeBuild folder, I cannot make my
first build using Xcode. I end up with a file not found on </div>
<div>
<div style="margin:0px;font-size:11px;font-family:Menlo;color:rgb(228,68,72)"><span style="color:#d28f5a">#include
</span><llvm-c/Analysis.h></div>
<div>in JavaScriptCore/llvm/LLVMHeaders.h</div>
<div>I actually had the same issue on my first build. After a
successful build from build-webkit, I can build again using
Xcode (not clean and build).</div>
<div>Any lead regarding why?</div>
</div>
</blockquote></div>
No idea, I only use build-webkit and make for building.<br>
A lot of people use Xcode so there must be a way to get it to work.<div class=""><br>
<blockquote type="cite">
<div>
<div>2) The Xcode projects is versioned on the repo. Is there
anyway to re-generate it automatically?</div>
<div>Having the Xcode project shared sounds very unsafe. What is
someone introduces a bug in it someday?</div>
</div>
</blockquote></div>
The Xcode project files are not generated, they are real project
files created by Xcode. WebKit contributors maintain 3 build systems
in parallel: Xcode, CMake, and VS.

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 href="https://trac.webkit.org/wiki/FeatureFlags" target="_blank">features
list</a>, a document about <a href="https://trac.webkit.org/wiki/AddingFeatures" target="_blank">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>

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>
