        <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

    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>

    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.

              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>
