      HI Benjamin,
      <div><br>
      </div>
      <div>Thanks for you answer.</div>
      <div><br>
      </div>
      <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>&lt;llvm-c/Analysis.h&gt;</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>
    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.<br>

        <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>

    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>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

                    <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>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/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,

                            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_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() =

              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>
