RapidXML 的编译错误

Question

我是 rapidXML 的新手，但第一印象并不积极，我制作了简单的 Visual Studio 6 C++ Hello World 应用程序并将 RapidXML hpp 文件添加到项目中，并在 main.cpp 中放入：

#include "stdafx.h"

#include < iostream >
#include < string >
#include "rapidxml.hpp"

using namespace std;
using namespace rapidxml;

int main ( )
{
    char x[] = "<Something>Text</Something>\0" ; //<<<< funktioniert, aber mit '*' nicht
    xml_document<> doc ;
    doc.parse<0>(x) ;
    cout << "Name of my first node is: " << doc.first_node()->name() << endl ;
    xml_node<>* node = doc.first_node("Something") ;
    cout << "Node 'Something' has value: " << node->value() << endl ;
} 

它不能编译，有什么帮助吗？ RapidXML 是否可以与 Visual Studio 6 一起运行？ 我得到的错误是：

Answer 1

我刚刚注意到您的错误与 rapidxml.cpp 有关。 那个文件是从哪里来的？？

RapidXML 是一个只有头文件的库。没有rapidxml.cpp，并且rapidxml.hpp 不能单独编译 - 您只需将其包含在您自己的文件中（如上面的main.cpp）即可使用它。

我对 VC++ 一无所知，但请尝试从 VC 项目中删除“rapidxml”并重新构建。

Answer 2

Visual C++ 6 可以追溯到 C++ 语言标准化之前。如果您在用它编译甚至模糊的现代代码时遇到问题，那么问题可能出在编译器而不是代码上。此类问题通常无法修复 - 您可能需要升级到更现代的编译器。

Answer 3

这在技术上是不合法的，但您可以尝试在您的 #include "rapidxml.hpp" 行上方插入以下代码：

namespace std
{
    typedef unsigned long size_t;
}

这将在 RapidXML 尝试使用之前（非法）将 size_t 注入到 std 命名空间中。如果真的可以编译，那么你可以搜索VC6的头文件，找出size_t的真正定义是什么，然后替换上面的unsigned long。
