Re: [webkit-dev] Some compile time data
Somewhat related to all this, if you'd like to keep an eye on your Xcode build times, you can use: $ defaults write com.apple.Xcode ShowBuildOperationDuration YES To have the build time show up in the status bar (at least with Xcode 3.x).

(The WebCoreExportGenerator project will get recompiled, but that's generally negligible compared to WebCore itself.) It seems likely that WebCore.exp.in is changing in conjunction with other files, in particular header files which are #included by WebKit. -Adam ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev
