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中我输入：

#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 ;
} 

它无法编译，有什么帮助吗？ RapidXML 可以与 Visual Studio 6 一起运行吗？ 我收到的错误是：

Answer 1

我刚刚注意到您的错误与 rapidxml.cpp 相关。 该文件从哪里来？

RapidXML 是一个仅包含标头的库。没有 rapidxml.cpp，并且 rapidxml.hpp 无法单独编译 - 您只需将其包含在您自己的文件中（例如 main.cpp< /code> 上面）来使用它。

我对 VC++ 一无所知，但尝试从 VC 项目中删除“rapidxml”并重建。

Answer 2

Visual C++ 6 的历史可以追溯到 C++ 语言标准化之前。如果您在使用它编译甚至是模糊的现代代码时遇到问题，那么问题很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

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

namespace std
{
    typedef unsigned long size_t;
}

这将（非法）将 size_t 注入 在 RapidXML 尝试使用 std 命名空间之前。如果确实可以编译，那么您可以搜索 VC6 头文件以找出 size_t 的真正定义是什么，并替换上面的 unsigned long 。
