Google v8 - Hello world

OS:Window 7

 

1.下载v8 zip：https://github.com/v8/v8，解压zip，重命名v8-master文件夹为v8。

2.下载安装svn：http://tortoisesvn.net/downloads.html。安装后确认C:\Program Files\TortoiseSVN\bin被加到环境变量path

3.在v8根目录下Check out gyp

运行cmd：cd v8，切换到v8的根文件夹

运行cmd: svn co http://gyp.googlecode.com/svn/trunk build/gyp, gyp安装到v8/build/gyp

4.在v8根目录下Check out ICU

运行cmd：svn co https://src.chromium.org/chrome/trunk/deps/third_party/icu46 third_party/icu

5.在v8根目录下Check out cygwin

运行cmd：svn co http://src.chromium.org/svn/trunk/deps/third_party/cygwin@231940 third_party/cygwin

6.下载安装python 2.7.X：http://www.python.org/download/，安装后将python.exe的路径添加到path环境变量中

7.运行cmd：python build\gyp_v8 -Dtarget_arch=x64（注：按装python后要打开新的cmd窗口，并且当前目录切换到v8的根文件夹）

8.运行cmd："C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\dev
env.exe" /build release build\all.sln，或者用VS2010打开v8\build\all.sln, build. Build成功后在v8\build\Release\lib生成v8_base.x64.lib，v8_nosnapshot.x64.lib，v8_snapshot.lib，icui18n.lib，icuuc.lib。

9.用VS2010创建一个c++ Win32 Console Application，添加x64 build配置。在linker里面导入v8_base.x64.lib，v8_nosnapshot.x64.lib，v8_snapshot.lib，icui18n.lib，icuuc.lib，ws2_32.lib，winmm.lib。

10.Copy/Paste以下代码到main函数

#include <v8.h>

using namespace v8;

int main(int argc, char* argv[]) {
  // Get the default Isolate created at startup.
  Isolate* isolate = Isolate::GetCurrent();

  // Create a stack-allocated handle scope.
  HandleScope handle_scope(isolate);

  // Create a new context.
  Handle<Context> context = Context::New(isolate);

  // Enter the 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::NewFromUtf8(isolate, "'Hello' + ', World!'");
  
  // Compile the source code.
  Handle<Script> script = Script::Compile(source);
  
  // Run the script to get the result.
  Handle<Value> result = script->Run();
  
  // Convert the result to an UTF8 string and print it.
  String::Utf8Value utf8(result);
  printf("%s\n", *utf8);
  return 0;
}

11.Build，如果出现以下linker error，添加msvcprtd.lib;MSVCRTD.lib到linker/input/Ignore Specific Default Libriries

>LIBCMT.lib(memcpy.obj) : error LNK2005: memmove already defined in MSVCRTD.lib(MSVCR100D.dll)
