包含<map>后编译错误

Compilation error after including <map>

本文关键字：编译 错误 map lt 包含 gt      更新时间：2023-10-16

我刚开始学习C++，试图学习一些基础知识。现在在Eclipse中使用gcc 5.2.1版本进行编译，项目是使用c++11参数进行编译的。

现在，当我尝试#include <map>时，就会出现include问题（只要编译器进入其中，我甚至还不使用map，只是尝试将其包含在内，这并不重要）。据我所知，地图本身有问题，但似乎不对。此处为简短的故障片段。

好的，我包含地图的文件

#ifndef MATHOPERATIONFACTORY_H_
#define MATHOPERATIONFACTORY_H_
#include <map>
#include <string>
class MathOperation;
class MathOperationFactory {
public:
    MathOperationFactory();
    virtual ~MathOperationFactory();
    virtual MathOperation& findOperationNamed(const std::string &name);
private:
    typedef std::map<std::string, MathOperation*> OperationMap;
    typedef OperationMap::iterator iterator;
    OperationMap _operationsByName;
};
#endif

这是一个与Cpputest的内存泄漏检测功能有关的问题。您可以应用Cpputest文档页面中描述的解决方案之一。

http://cpputest.github.io/manual.html#memory_leak_detection

我可以通过确保<地图>包含在任何CppUTest相关的包含之前。

示例：

class1.h:

#include <map>
.
.
//your code for class 1 business logic

class1_test.cpp:

#include "class1.h"
//other include
#include <CppUTest/TestHarness.h> // at very end

在任何要包含CppUtest标头的地方遵循此规则

所以我没有找到确切的答案，但通过简单地将所有项目文件移到新项目中，成功地完全解决了这个问题。这意味着这个问题在某种程度上与项目设置有关，我比较了两个项目的编译器设置，它们是相同的，所以原因仍然笼罩着一层非常精细的钻石硬雾。
