webkit在win32下的编译规则（三）

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

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"

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: #!/usr/bin/bash

auto-version.sh这个脚本主要是根据D:/tools/cygwin/home/xufan/WebKit/WebKitLibraries/win/tools/scripts/VERSION，D:/tools/cygwin/home/xufan/WebKit/WebKitLibraries/win/tools/scripts/COPYRIGHT-END-YEAR以及当前时间等生成D:/tools/cygwin/home/xufan/WebKit/WebKitBuild/Debug\_Cairo\_CFLite/obj/JavaScriptCore/include/autoversion.h这个描述版本信息的头文件，这个头文件在生成后的格式如下：

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：

[![image][]][image 1]

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：

[![image][image 2]][image_image 2]

这些vsprops文件包含：

../../../../WebKitLibraries/win/tools/vsprops/FeatureDefinesCairo.vsprops  
../../../../WebKitLibraries/win/tools/vsprops/common.vsprops  
../../../../WebKitLibraries/win/tools/vsprops/release.vsprops  
../../../../WebKitLibraries/win/tools/vsprops/WinCairo.vsprops  
./WTFCommon.vsprops

FeatureDefinesCairo.vsprops这个文件主要是用来定义一些宏，这些宏用来开启和关闭webkit的特性，例如3D\_CANVAS，BLOB，DATABASE，DATAGRID，SVG等。如果要开启对应的属性，只需要修改UserMacro里面的Value属性即可。

WTFCommon.vsprops这个文件定义了wtf这个工程依赖的头文件目录和库等。

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。
