            I think it was blocked, maybe because of the attachment that
            I remove this time.</div>
          <div><br>
          </div>
          <div>Iím new on this mailing so Iíll start by introducing
            myself:</div>
          <div>My name Jacques-Olivier Hachť (J-O), Iím working for
            Temasys Communication, and Iím entering the WebKit project
            to work on the implementation of WebRTC inside WebKit.</div>
          <div>For those who would be following the WebRTCís news, Iím
            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&nbsp;171167</li>
              <li>Iím on master</li>
              <li>I suppose Iím using the regular Mac port as I didnít
                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.&nbsp;</div>
          <div>I have to say that I faced a lack of documentation on
            this area. I found the&nbsp;<a moz-do-not-send="true" href="https://trac.webkit.org/wiki/FeatureFlags">features
              list</a>, a document about&nbsp;<a moz-do-not-send="true" href="https://trac.webkit.org/wiki/AddingFeatures">how to
              add a new feature</a>&nbsp;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&nbsp;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>&nbsp; &nbsp; class Observer {</div>
            <div>&nbsp; &nbsp; public:</div>
            <div>&nbsp; &nbsp; &nbsp; &nbsp; virtual void didAddOrRemoveTrack() = 0;</div>
            <div>&nbsp; &nbsp; &nbsp; virtual ~Observer() {};</div>
            <div>&nbsp; &nbsp; };</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.&nbsp;</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>

    </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>
