webkit在win32下的编译规则（二）

现在的webkit分为4个Floder：Javascript Folder，Tools，WebCore Folder，Webkit2 Folder，WebkitCom Folder，这5个目录的编译顺序基本是：Javascript Folder-》WebCore Folder-》WebkitCom Folder-》Webkit2 Folder-》Tools（有些子工程的顺序并不是这样的），下面就以这几个目录为单位来说明webkit的编译规则。

1. Javascript Folder

这个目录下有5个工程：JavaScriptCore, JavaScriptGenerated, jsc, testapi, WTF。编译顺序是：JavaScriptGenerated-》WTF-》 JavaScriptCore-》testapi-》jsc。testapi和jsc其实是在比较后面编译的，应为它们依赖于Tools下的FindSafari工程。

首先看JavaScriptGenerated的工程属性，可以看到这个工程是用nmake编译的,如下图：

JavaScriptGenerated的工程文件在D: oolscygwinhomexufanWebKitJavaScriptCoreJavaScriptCore.vcprojJavaScriptC

oreJavaScriptCoreGeneratedCommon.vsprops，内容如下：

<?xml version="1.0" encoding="Windows-1252"?>
<VisualStudioPropertySheet
ProjectType="Visual C++"
Version="8.00"
Name="JavaScriptCoreGeneratedCommon"
OutputDirectory="$(WebKitOutputDir)lib"
IntermediateDirectory="$(WebKitOutputDir)obj$(ProjectName)$(ConfigurationName)"
>
<Tool
Name="VCNMakeTool"
BuildCommandLine="%SystemDrive%cygwininwhich.exe bash
if errorlevel 1 set PATH=%SystemDrive%cygwinin;%PATH%
cmd /c

nmake /nologo -f JavaScriptCoreGenerated.make"
ReBuildCommandLine="%SystemDrive%cygwininwhich.exe bash
if errorlevel 1 set PATH=%SystemDrive%cygwinin;%PATH%
cmd /c

nmake /nologo -f JavaScriptCoreGenerated.make clean
nmake -f JavaScriptCoreGenerated.make"
CleanCommandLine="%SystemDrive%cygwininwhich.exe bash
if errorlevel 1 set PATH=%SystemDrive%cygwinin;%PATH%
cmd /c

nmake /nologo -f JavaScriptCoreGenerated.make clean"
/>
</VisualStudioPropertySheet>

其中编译这个工程使用的命令行（BuildCommandLine）为：

%SystemDrive%cygwininwhich.exe bash
if errorlevel 1 set PATH=%SystemDrive%cygwinin;%PATH%
cmd /c

nmake /nologo -f JavaScriptCoreGenerated.make

从上面可以看到，首先执行which命令在环境变量PATH里面查找bash的位置，如果查找不成功，则将cygwin下面的bin目录加到环境变量里面PATH。接着调用cmd /c, 表示当执行完相应的命令(在命令提示符中)后自动退出命令提示符，这个接的命令为空，应该只是用于刷新命令行环境。最后用nmake去编译JavaScriptCoreGenerated.make这个文件了，JavaScriptCoreGenerated.make文件内容如下：
