Question

首先，我不得不说我只是初学c ++编程，所以这是我第一次尝试设置sfml 2.4.0。我在Ubuntu 16.04 LTS上运行Code :: Blocks。带有错误的脚本与SFML官方网站上的教程相同：

#include <iostream>
#include <SFML/Graphics.hpp>
#include <SFML/Window.hpp>
#include <SFML/System.hpp>
using namespace std;

int main()
{
sf::RenderWindow finestra (sf::VideoMode(100,100), "Ciao!");
    sf::CircleShape cerchio (100.f);
    cerchio.setFillColor(sf::Color::Blue);
    while (finestra.isOpen())
    {
    sf::Event evento;
    while (finestra.pollEvent(evento))
    {
    if (evento.type == sf::Event::Closed)
    finestra.close();
    }
    finestra.clear();
    finestra.draw(cerchio);
    finestra.display();
    }
    return 0;
}

不要介意变量和字符串的奇怪名称，我只是想使用我的语言术语更熟悉脚本。我尝试构建并运行脚本后出现的错误是这个（“riferimento non definito a”表示“未定义引用”）：

这里有项目的构建选项（我没有提到的那些被设置为默认值）：

搜索目录/编译器：/home/user/Downloads/SFML-2.4.0/include

搜索目录/链接器：/home/user/Downloads/SFML-2.4.0/lib（我还试图添加另一个“/ include”但它也不起作用）

链接器设置/调试/ sfml-graphics-s-d SFML窗口-S-d sfml-system-s-d

链接器设置/发布/ sfml-graphics-s SFML窗口-S SFML系统-S

编译器设置/ #define / SFML_STATIC

我在论坛上搜索了一周以上非常单一的帖子，但我从来没有发现和我一样的问题。如果您需要其他信息，请提前感谢。

未定义的引用是opengl。您需要添加opengl库。

在opengl32的窗口中，在所有sfml库之后添加

在linux中，我不太确定，但它看起来像GL

（奇怪的是SFML文档没有提到这一点。https://www.sfml-dev.org/tutorials/2.4/start-cb.php的windows版本确实提到了依赖关系，但截图没有显示库引用.linux构建指令根本没有提到它。！当你开始工作时，你应该让他们更新文档。）
