代碼塊中的SFML項目不起作用

Question

代碼塊版本：16.01 SFML版本：2.4.2

我在Codeblocks中創建了SFML 2.0項目。 我選擇了“新建項目”->“ SFML項目”->“ SFML 2.0”。 我將此代碼復制到main.cpp文件中並進行了編譯。

#include<SFML/Graphics.hpp>

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

    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;
}

構建代碼時，出現以下錯誤：

我嘗試同時使用靜態和動態版本，但均未成功。 什么地方出了錯？

Answer 1

原來我使用的是錯誤版本的SFML。 我下載了GCC 4.7 TDM（SJLJ- 32位版本），它可以正常工作。
