首先来看WTF这个project，这个project的Pre-build event如下：
1: REM Do not edit from the Visual Studio IDE! Customize via a $(ProjectName)PreBuild.cmd file. 2: if not exist "$(ProjectDir)$(ProjectName)PreBuild.cmd" exit /b 3: 4: set CONFIGURATIONBUILDDIR=$(ConfigurationBuildDir) 5: set CONFIGURATIONNAME=$(ConfigurationName) 6: set INPUTDIR=$(InputDir) 7: set INPUTFILENAME=$(InputFileName) 8: set INPUTPATH=$(InputPath) 9: set INTDIR=$(IntDir) 10: set LIBRARYCONFIGSUFFIX=$(LibraryConfigSuffix) 11: set OUTDIR=$(OutDir) 12: set PLATFORMNAME=$(PlatformName) 13: set PROJECTDIR=$(ProjectDir) 14: set PROJECTFILENAME=$(ProjectFileName) 15: set PROJECTNAME=$(ProjectName) 16: set PROJECTPATH=$(ProjectPath) 17: set SOLUTIONDIR=$(SolutionDir) 18: set SOLUTIONFILENAME=$(SolutionFileName) 19: set SOLUTIONNAME=$(SolutionName) 20: set SOLUTIONPATH=$(SolutionPath) 21: set TARGETDIR=$(TargetDir) 22: set TARGETEXT=$(TargetExt) 23: set TARGETFILENAME=$(TargetFileName) 24: set TARGETPATH=$(TargetPath) 25: set WEBKITCONFIGSUFFIX=$(WebKitConfigSuffix) 26: set WEBKITDLLCONFIGSUFFIX=$(WebKitDLLConfigSuffix) 27: 28: REM If any of the above variables didn't exist previously and 29: REM were set to an empty string, set will set the errorlevel to 1, 30: REM which will cause the project-specific script to think the build 31: REM has failed. This cmd /c call will clear the errorlevel. 32: cmd /c 33: 34: "$(ProjectDir)$(ProjectName)PreBuild.cmd"这些脚本首先利用vs自带的一些内置变量来设置环境变量，然后调用"$(ProjectDir)$(ProjectName)PreBuild.cmd"这个脚本，展开后的路径是D:/tools/cygwin/home/xufan/WebKit/Source/JavaScriptCore/JavaScriptCore.vcproj/JavaScriptCore/JavaScriptCorePreBuild.cmd。从上面的28-31行可以看出，cmd /c的主要作用是为了清除errorlevel。JavaScriptCorePreBuild.cmd这个脚本的内容如下：
1: %SystemDrive%/cygwin/bin/which.exe bash 2: if errorlevel 1 set PATH=%SystemDrive%/cygwin/bin;%PATH% 3: cmd /c 4: if exist "%CONFIGURATIONBUILDDIR%/buildfailed" grep XX%PROJECTNAME%XX "%CONFIGURATIONBUILDDIR%/buildfailed" 5: if errorlevel 1 exit 1 6: echo XX%PROJECTNAME%XX > "%CONFIGURATIONBUILDDIR%/buildfailed" 7: 8: bash "%WEBKITLIBRARIESDIR%/tools/scripts/auto-version.sh" "%INTDIR%"JavaScriptCorePreBuild.cmd首先检查前面的编译有没有问题，如果没有问题，就会调用D:/tools/cygwin/home/xufan/WebKit/WebKitLibraries/win/tools/scripts/auto-version.sh这个perl脚本，内容如下：

1: #define __VERSION_TEXT__ "533+ - Mon Jan 31 12:26:06 2011 - r77102" 2: #define __BUILD_NUMBER__ "533+ - Mon Jan 31 12:26:06 2011 - r77102" 3: #define __BUILD_NUMBER_SHORT__ "533+" 4: #define __VERSION_MAJOR__ 5 5: #define __VERSION_MINOR__ 33 6: #define __VERSION_TINY__ 0 7: #define __VERSION_BUILD__ 0 8: #define __BUILD_NUMBER_MAJOR__ 533 9: #define __BUILD_NUMBER_MINOR__ 0 10: #define __BUILD_NUMBER_VARIANT__ 0 11: #define __SVN_REVISION__ 77102 12: #define __COPYRIGHT_YEAR_END_TEXT__ "2011"这些信息会体现在javascriptcore.dll这个文件的版本信息里面，如下图：
执行完prebuild脚本后，就要开始编译了。wtf这个project有一些属性是从别的vsprops文件集成来的，如下图：
这些vsprops文件包含：

需要注意的是，FeatureDefinesCairo.vsprops,common.vsprops,release.vsprops,WinCairo.vsprops是大部分webkit工程都会继承的，因此修改后会一些所有继承这几个文件的工程。例如如果你想将webkit编译依赖的crt由Multi-threaded DLL(/MD)改为Multi-threaded (/MT)，只需要修改release.vsprops这个文件的RuntimeLibrary这个属性即可。
WTF这个工程的编译过程就和普遍的vc工程一样了，这里就不介绍了。
WTF这个工程的PreLink Event和PostBuild Event主要是调用WTFPreLink.cmd和WTFPostBuild.cmd，这两个bat都比较简单，就不介绍了。
