在 Visual Studio 代码中调试 SFML 代码时出错

Question

我在 linux 上使用 SFML 库创建了一个项目，它工作得很好。我通过启动这个脚本 exec.sh:

来启动它

g++ -c main.cpp -I/usr/include
g++ main.o -o sfml-app -L/usr/lib -lsfml-graphics -lsfml-window -lsfml-system
export LD_LIBRARY_PATH=/usr/lib && ./sfml-app

这里是 main.cpp 文件中的代码：

#include <SFML/Graphics.hpp>

int main()
{
    sf::RenderWindow window(sf::VideoMode(200, 200), "SFML works!");
    sf::CircleShape shape(100.f);
    shape.setFillColor(sf::Color::Blue);

    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;
}

但问题是我无法调试它，并且在尝试时总是出错。有人可以给我建议或解释我该怎么做吗？我需要 linux 的解决方案，我是这个 OC 和 [=44= 的新手].

这是使用 g++ 调试后的错误：

尝试将库安装到您的系统路径。对于基于 Arch Linux -

sudo pacman -S sfml

基于 Debian Linux -

sudo apt-get install sfml-dev

并且只需使用以下 g++ 命令 -

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

最好用一个IDE。您可以使用

Code Blocks
Code Lite
Apache netbeans
Eclipse

如果您熟悉 cmake，您可以使用-

Kdevelop
