I think my understanding of what is happening improved, but I’m still stuck at the same point:</div><div><br></div><div>I read some more code and did some research about the Supplement and Supplementable classes.</div><div>I mainly found <a href="http://trac.webkit.org/wiki/Modules">this page</a> which explains that Supplements are used to extract code from “massive” classes and make then more manageable and maintainable.</div><div>Please correct me if I am wrong.</div><div><br></div><div>Anyway, it doesn’t change that my program has no Supplement for the key “UserMediaController”.</div><div>It looks like most of the supplements are being provided in two places:</div><div><ul class="MailOutline"><li>WebKit::WebView::_commonInitializationWithFrameName</li><li>WebKit2::WebPage ’s constructor</li></ul><div>is there any other place where it should be done?</div><div><br></div><div>WebView actually contains a call to WebCore::provideUserMediaTo which creates a supplement, but my debugging show that _commonInitializationWithFrameName is never called.</div><div>WebPage’s constructor does not generate a UserMediaController supplement.</div><div><br></div><div><div>My understanding of the WebView is that it is the rectangle in which the webpages are rendered. Is this assumption correct?</div></div><div>I don’t understand why _commonInitializationWithFrameName is never called when browsing. From the name of the function, I would expect it to be called right after the memory allocation.</div><div><br></div><div>This leaves me with 2 options:</div><div>1) Find a way to trigger _commonInitializationWithFrameName.</div><div>I have no idea of how to do that at the moment</div><div><br></div><div>2) Duplicate the call to WebCore::provideUserMediaTo in WebKit2::WebPage.</div><div>I understand this is what is being done for the geolocation supplement.</div><div>I started to implement this solution, but it requires to translate Objective-C++ code into C++, and I am afraid that the file inclusion might never end.</div><div><br></div><div>Does any one of these solutions sound more reliable than the other for you?</div><div><br></div><div>Thanks in advance,</div><div>J-O H</div><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>

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.

<div>Note: I already sent this email, but I didn’t
get any answer, nor can I see the thread in the

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>

This code has not been updated in a while, you will have
to fix some stuff here and there to get it to do anything.<br>

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>

<div>Why is the precompiled header not re-built

</blockquote>
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>
