错误 LNK2001:未解析的外部符号“公共:静态类 sf::RenderStates const sf::RenderStates::Default" [英] error LNK2001: unresolved external symbol "public: static class sf::RenderStates const sf::RenderStates::Default"

问题描述

代码如下:

引擎.h

#include <SFML/Audio.hpp>
#include <SFML/Config.hpp>
#include <SFML/Graphics.hpp>
#include <SFML/Network.hpp>
#include <SFML/OpenGL.hpp>
#include <SFML/System.hpp>
#include <SFML/Window.hpp>

class Engine
{
public:
    Engine(sf::RenderWindow & wd);
    void run(sf::RenderWindow & wd);

    sf::Sprite player;
    sf::Texture playerTexture;

};

引擎.cpp

#include "Engine.h"

Engine::Engine(sf::RenderWindow & wd) : player(), playerTexture()
{

}

void Engine::run(sf::RenderWindow & wd)
{
    if (!playerTexture.loadFromFile("image/char.png")) {}
    player.setTexture(playerTexture);

    while (wd.isOpen())
    {
        sf::Event event;
        while (wd.pollEvent(event))
        {
            if (event.type == sf::Event::Closed)
                wd.close();
        }

        wd.clear();
        wd.draw(player);
        wd.display();
    }
}

main.cpp

#include <SFML/Audio.hpp>
#include <SFML/Config.hpp>
#include <SFML/Graphics.hpp>
#include <SFML/Network.hpp>
#include <SFML/OpenGL.hpp>
#include <SFML/System.hpp>
#include <SFML/Window.hpp>

#include "Engine.h"

int main()
{
    sf::RenderWindow * wd = new sf::RenderWindow(sf::VideoMode(800, 600), "Lumia");
    Engine * eg = new Engine(*wd);
    eg->run(*wd);

    return EXIT_SUCCESS;
}

如果我删除 wd.draw(player);从 Engine.cpp 中，不会发生此错误，似乎我无法绘制任何东西，我是否定义了默认构造函数而不调用它?还是我以错误的方式传递参数?请解释为什么会出现这个错误并给我一个合理的解决方案，感谢进一步的回答.

if I delete wd.draw(player); from Engine.cpp, this error doesn't occur, it seems like I can't draw anything, am I defining a default constructor and not calling it? Or am I passing arguments in aa wrong way? Please explain me why this error occurs and give me a reasonably solution, thanks for further answers.

推荐答案

您应该将 *.lib 文件的文件名添加到 vs 的链接器中.

You should add your file names of *.lib files to vs' linker.

步骤:

1. 打开您的项目属性页面.(在 vs 中按 Alt+F7).
2. 展开配置属性".
3. 展开链接器".
4. 您将在链接器"下找到输入"项，然后单击输入".
5. 在右侧，您会找到一项附加依赖项".
6. 在此处添加您的 lib 文件名.(例如 lib1.lib;lib2.lib...，用分号分隔库).
