无法在 Windows 上使用 g++ 编译带有 SFML 的 *.cpp 文件

问题描述 投票：0回答：1

我正在尝试编译 *.cpp 文件：

#include <SFML/Graphics.hpp>

using namespace sf;

int main()
{
    
    RenderWindow window(VideoMode(400, 400), L"New project", Style::Default);
    
    window.setVerticalSyncEnabled(true);
       
    CircleShape shape(100.f,3); 
    shape.setPosition(100, 100);           
    shape.setFillColor(Color::Magenta);
        
    while (window.isOpen())
    {
        Event event;
        while (window.pollEvent(event))
        {
            if (event.type == Event::Closed)
                window.close();
        }
        
        window.clear(Color::Blue);
        window.draw(shape);
        window.display();
    }
    return 0;
}

我将 

g++ Durak.cpp -o output.exe -I"C:\Users\dalvo\IT\SFML (MinGW)\SFML-3.0.0\include" -L"C:\Users\dalvo\IT\SFML (MinGW)\SFML-3.0.0\lib" -lsfml-graphics -lsfml-window -lsfml-system
放入控制台，但出现错误：

我的版本如下： g++（Rev3，由 MSYS2 项目构建）13.2.0； SFML-3.0.0。 我从 ChatGpt 询问的命令提示文本行。 我从带有指南的网站复制粘贴的代码：https://habr.com/ru/articles/703500/。其他人成功地使用了此代码，但我没有。请帮助我，我已经解决这个问题好几天了（已经想退出编程了......）

由于您使用的是 SFML3，因此需要进行一些更改。大多数以前具有分别获取高度和宽度的重载的函数现在都具有采用 

sf::Vector2u
或类似值的构造函数或成员函数。

还有一个迁移到 SFML3 指南。只需在搜索框中输入

VideoMode
，它就会告诉你如何在SFML3中正确拨打电话。

您的程序已解决问题：

#include <SFML/Graphics.hpp>

using namespace sf;

int main() {
    RenderWindow window(VideoMode({400, 400}), L"New project", Style::Default);
    //                            ^        ^

    window.setVerticalSyncEnabled(true);

    CircleShape shape(100.f, 3);
    shape.setOrigin(shape.getGeometricCenter()); // getGeometricCenter: new in SFML3
    shape.setPosition({200, 200});
    //                ^        ^
    shape.setFillColor(Color::Magenta);

    while(window.isOpen()) {
        while(auto event = window.pollEvent()) { // polling in SFML3
            if(event->is<sf::Event::Closed>()) {
                window.close();
            } else if(const auto* keyPressed =
                          event->getIf<sf::Event::KeyPressed>()) {
                if(keyPressed->scancode == sf::Keyboard::Scancode::Escape)
                    window.close();
            }
        }

        window.clear(Color::Blue);
        window.draw(shape);
        window.display();
        shape.rotate(degrees(1.0f)); // rotate takes an sf::Angle in SFML3
    }
}
