如何在ubuntu中安装SFML？

Question

我下载了 SFML，然后将其所有标头复制到usr/local/include/中，并将其所有库复制到usr/local/lib/中。

我在桌面中有一个名为main.cpp的文件，我想编译它。

首先我这样做了：-

g++ -c main.cpp

之后，当我尝试这样做时：-

g++ main.o -o sfml-app -lsfml-graphics -lsfml-window -lsfml-system

它给了我：-

我已正确安装所有这些必需的依赖项： https://github.com/SFML/SFML/wiki/Tutorial%3A-Installing-SFML-dependencies

我是否错过了任何必需的步骤？

要首先在 Ubuntu 中安装它，请在终端中运行以下命令 -

sudo apt-get install libsfml-dev

确保您已经有编译器（GCC），如果没有，则使用 make 安装它

sudo apt-get install build-essential

然后为了测试这一点，创建一个像这样的简单 SFML 应用程序

#include <SFML/Graphics.hpp>

int main(int argc, char const *argv[])
{
    sf::RenderWindow window(sf::VideoMode(200,200), "Hello From SFML");
    sf::CircleShape shape(100.f);
    shape.setFillColor(sf::Color::Magenta);

    while (window.isOpen())
    {
        sf::Event event;
        while (window.pollEvent(event))
        {
            if(event.type == sf::Event::Closed){
                window.close();
            }
        }
        window.clear();
        window.draw(shape);
        window.display();
        
    }

    return 0;
}

现在在存储库中创建一个makefile与main.cpp

compile:./main.cpp
    g++ -c ./main.cpp
    g++ main.o -o app -lsfml-graphics -lsfml-window -lsfml-system

run:
    ./app

现在编译它运行以下命令

compile:./main.cpp
    g++ -c ./main.cpp
    g++ main.o -o app -lsfml-graphics -lsfml-window -lsfml-system

run:
    ./app

最后运行以下命令

make compile
