VS2012的Node.js模塊：故障排除LNK2005/LNK1169錯誤

我工作在Visual Studio中的Node.js模塊，並具有以下文件結構：VS2012的Node.js模塊：故障排除LNK2005/LNK1169錯誤

load.h

#include <string> 
#include <v8.h> 

void property_guard(v8::Local<v8::Object> obj, v8::Local<v8::String> name, const std::string path);

負荷。 CPP

#include "load.h" 

void property_guard(v8::Local<v8::Object> obj, v8::Local<v8::String> name, const std::string path) { 
    if (!obj->Has(name)) { 
     throw path + " does not exist"; 
    } 
}

的main.cpp

#include <string> 
#include <node.h> 
#include <v8.h> 
#include "load.h" 

void integer_type_guard(v8::Local<v8::Value> obj, const std::string path) { 
    if (!obj->IsInt32()) { 
     throw path + " is not an integer"; 
    } 
} 

int get_int_property(v8::Local<v8::Object> obj, v8::Local<v8::String> name, const std::string path) { 
    property_guard(obj, name, path); 
    v8::Local<v8::Value> value = obj->Get(name); 
    integer_type_guard(value, path); 
    return value->Int32Value(); 
}

我期望結構是正確的，但我得到的Visual Studio和類似的錯誤，當我編譯節點GYP項目：

error LNK2005: "public: class v8::Object * __cdecl v8::Handle<class v8::Object>::operator->(void)const " ([email protected]@[email protected]@@[email protected]@[email protected]@XZ) already defined in node.lib(node.exe) C:\...\load.obj 
error LNK1169: one or more multiply defined symbols found C:\...\Test1.dll

從main.cpp中包括去除node.h刪除錯誤（我需要它來註冊模塊）。將property_guard方法移至main.cpp也解決了這個問題。

在這種情況下將聲明移動到其他文件的正確方法是什麼？
