WebCore Folder下面的有3個工程：QTMovieWin，WebCore，WebCoreGenerated，編譯的順序是：WebCoreGenerated-》QTMovieWin-》QTMovieWin。
首先來看WebCoreGenerated這個工程，這個工程的NMake Build Comand Line如下：
%SystemDrive%/cygwin/bin/which.exe bash if errorlevel 1 set PATH=%SystemDrive%/cygwin/bin;%PATH% cmd /c if exist "$(ConfigurationBuildDir)/buildfailed" grep XX$(ProjectName)XX "$(ConfigurationBuildDir)/buildfailed" if errorlevel 1 exit 1 echo XX$(ProjectName)XX > "$(ConfigurationBuildDir)/buildfailed" set CONFIGURATIONBUILDDIR=$(ConfigurationBuildDir) bash build-generated-files.sh "$(ConfigurationBuildDir)" "$(WebKitLibrariesDir)" "$(WebKitVSPropsRedirectionDir)../../../WebKitLibraries/win" cairo bash migrate-scripts.sh "$(ConfigurationBuildDir)/obj/WebCore/scripts" cmd /C copyForwardingHeaders.cmd cairo curl cmd /C copyInspectorFiles.cmd if exist "$(ConfigurationBuildDir)/buildfailed" del "$(ConfigurationBuildDir)/buildfailed"
比較重要的是下面四句：
bash build-generated-files.sh "$(ConfigurationBuildDir)" "$(WebKitLibrariesDir)" "$(WebKitVSPropsRedirectionDir)../../../WebKitLibraries/win" cairo bash migrate-scripts.sh "$(ConfigurationBuildDir)/obj/WebCore/scripts" cmd /C copyForwardingHeaders.cmd cairo curl cmd /C copyInspectorFiles.cmd
首先來看build-generated-files.sh：

這個腳本比較重要的是倒數兩句。倒數第二句將vsprops裏面的值轉換爲FEATURE_DEFINES這個環境變量。倒數第一句調用make來編譯$WebCore/DerivedSources.make （D:/tools/cygwin/home/xufan/WebKit/Source/WebCore/DerivedSources.make）這個文件，-j選項同時進行編譯的任務數（多核很有優勢）。DerivedSources.make的文件內容如下：

VPATH這個變量定義了Make在哪裏尋找文件，使用VPATH有一個隱患: VPATH在每個目錄中搜索所有的source文件，如果一個相同的文件名出現在不同的目錄中, VPATH將第一個搜索到的文件作爲結果，使用vpath就比VPATH更靈活些。不夠webkit暫時沒出這個問題，所以VPATH已經夠用。後面很多規則沒有指定路徑，靠的就是這個VPATH，將路徑展開交給了make工具。
DOM_CLASSES定義了一大堆要根據IDL文件生成的h和cpp文件列表，大概有450個，生成的文件在D:/tools/cygwin/home/xufan/WebKit/WebKitBuild/Debug_Cairo_CFLite/obj/WebCore/DerivedSources目錄下。
JS_DOM_HEADERS將所有的DOM_CLASSES值加了JS前綴，並去除了其中的JSMediaQueryListListener.h JSEventListener.h JSEventTarget.h這幾個文件。
WEB_DOM_HEADERS在編譯選項中包括BUILDING_WX時，將所有的DOM_CLASSES值加了WebDOM前綴，並去除了其中的WebDOMXSLTProcessor.h WebDOMEventTarget.h。在cairo win32編譯環境下，這個變量爲空。
makefile的入口是all這條規則，all依賴於$(JS_DOM_HEADERS),$(WEB_DOM_HEADERS),JSJavaScriptCallFrame.h,CSSGrammar.cpp,CSSPropertyNames.h,CSSValueKeywords.h,ColorData.cpp,DocTypeStrings.cpp,HTMLElementFactory.cpp,HTMLEntityTable.cpp,HTMLNames.cpp,WMLElementFactory.cpp,WMLNames.cpp,JSSVGElementWrapperFactory.cpp,SVGElementFactory.cpp,SVGNames.cpp,UserAgentStyleSheets.h,XLinkNames.cpp,XMLNSNames.cpp,XMLNames.cpp,MathMLElementFactory.cpp,MathMLNames.cpp,XPathGrammar.cpp,tokenizer.cpp,HeaderDetection.h，下面就介紹makefile如何對這些文件進行處理。
