1) 签出源代码

svn checkout http://v8.googlecode.com/svn/trunk/ v8

2)在v8根目录下签出gyp

svn co http://gyp.googlecode.com/svn/trunk build/gyp

3)在v8根目录下签出python和cygwin

svn co http://src.chromium.org/svn/trunk/tools/third_party/python_26@89111 third_party/python_26

svn co http://src.chromium.org/svn/trunk/deps/third_party/cygwin@66844 third_party/cygwin

4)添加python和cygwin的路径到环境变量

set path="%cd%\third_party\python_26";"%cd%\third_party\cygwin\bin;%path%

5) 生成编译项目文件(gyp是json配置文件和python脚本的工具集，是一个元编译系统，用来生成真正的编译系统，比如常见的Makefile, *.sln, *.vcproj 等）

python build\gyp_v8

6) 打开编译项目编译(在命令行里面用start方式打开sln文件，可以让visual studio编译系统继承环境变量)

start build\all.sln

7) 编译

在 build/{debug,release}/lib 下得到4个静态库文件(windows上默认也是静态库文件)

preparser_lib.lib
v8_base.lib
v8_nosnapshot.lib
v8_snapshot.lib

头文件在v8根目录下的include文件夹里面

8) 测试

testv8.cxx

// testv8.cpp : Defines the entry point for the console application.//#include <v8.h>using namespace v8;int main(int argc, char* argv[]) {// Create a stack-allocated handle scope.HandleScope handle_scope;// Create a new context.Persistent<Context> context = Context::New();// Enter the created context for compiling and// running the hello world script. Context::Scope context_scope(context);// Create a string containing the JavaScript source code.Handle<String> source = String::New("var x='xyziamheres2///sdfsdf123'; x.match(/\\d{3,3}/);");// Compile the source code.Handle<Script> script = Script::Compile(source);// Run the script to get the result.Handle<Value> result = script->Run();// Dispose the persistent context.context.Dispose();// Convert the result to an ASCII string and print it.String::AsciiValue ascii(result);printf("%s\n", *ascii);return 0;}

在testv8.cxx所在目录下新建文件夹

v8/inc

v8/lib/debug

v8/lib/release

把生成lib文件和头文件一起复制到相应的目录

9) 编译测试testv8

cl /Od /I "v8/inc" /D "WIN32" /D "_DEBUG" /D "_CONSOLE" /D "_UNICODE" /D "UNICODE" /Gm /EHsc /RTC1 /MDd /Fo"Debug\\" /Fd"Debug\vc90.pdb" /W3 /c /ZI /TP ".\testv8.cpp"

link "/OUT:C:\Users\Administrator\Documents\Visual Studio 2008\Projects\testv8\Debug\testv8.exe" /INCREMENTAL "/LIBPATH:v8/lib/Debug" /MANIFEST "/MANIFESTFILE:Debug\testv8.exe.intermediate.manifest" "/MANIFESTUAC:level='asInvoker' uiAccess='false'" /DEBUG "/PDB:c:\Users\Administrator\Documents\Visual Studio 2008\Projects\testv8\Debug\testv8.pdb" /SUBSYSTEM:CONSOLE /DYNAMICBASE /NXCOMPAT /MACHINE:X86 v8_snapshot.lib v8_base.lib preparser_lib.lib ws2_32.lib winmm.lib kernel32.lib user32.lib gdi32.lib winspool.lib comdlg32.lib advapi32.lib shell32.lib ole32.lib oleaut32.lib uuid.lib odbc32.lib odbccp32.lib

10) 运行testv8
