c++ - '渲染' : 'class' type redefinition (C2011)

Question

关于这个主题，Stack Overflow 上有很多类似的问题。

我正在创建一个包含多个文件(.cpp 和 .h)的项目。我收到错误:

C2011: 'Render': 'class' type redefinition

我已经看过了。有些人说使用守卫，所以我在所有头文件上使用 #pragma once。有人说 header 被多次包含，但守卫会阻止这种情况。那我做错了什么？

代码:

立方体.h

#pragma once

char orientation(int sides, int hV);

std::vector<char> visOrd(std::string *xOrd, int *pov, int ord);

std::vector<int> convertColour(std::vector<std::string> rlBoxCol);

std::tuple<std::vector<int>, std::vector<std::string>> organiseLayers(std::vector<int> boxCoords, std::vector<std::string> rlBoxCol, std::vector<float> rot);


class Render
{
private:
    std::vector<float> rot;
    std::vector<int> boxCoords;
    std::vector<std::string> rlBoxCol;
    int gridSize;
    int cubeSize;
    std::vector<int> offset;

public:
    Render();


    void setRotation(std::vector<float> setRot);
    std::vector<float> getRotation();

    void setCoordinates(std::vector<int> setBoxCoords);
    std::vector<int> getCoordinates();

    void setColours(std::vector<std::string> setRlBoxCol);
    std::vector<std::string> getColours();

    void setSizeOfGrid(int setGridSize);
    int getSizeOfGrid();

    void setSizeOfCubes(int setCubeSize);
    int getSizeOfCubes();

    void setOffset(std::vector<int> setOffset);
    std::vector<int> getOffset();


    void display();
};

编辑:

我现在已经按照您所说的方式更改了代码。现在我收到错误 LNK2005 和 LNK1169。现在出了什么问题？

编辑 2:(错误)

Answer 1

您的 Cubes.cpp 确实重新定义了 Render 类。通常，.h 文件具有类原型(prototype)，而 .cpp 文件定义方法。

尝试将其添加到 Cubes.cpp 的顶部:

#include "Cubes.h"

从 Cubes.cpp 的顶部删除它:

class Render
{
private:
    std::vector<float> rot;
    std::vector<int> boxCoords;
    std::vector<std::string> rlBoxCol;
    int gridSize;
    int cubeSize;
    std::vector<int> offset;

public:   

并将其从底部移除:

};
