我一直在寻找答案，但我发现的只是一些类似的问题，但答案对我一点帮助都没有。
我正在尝试将 SFML 用于最终项目(我们想创建一个像 Minigore 这样的游戏)，我们正在尝试加载图像，然后将其放入 Sprite 中。
这是我的代码:
#include <SFML/System.hpp>
#include <SFML\Graphics.hpp>
#include <iostream>
int main()
{
sf::RenderWindow App(sf::VideoMode(800, 600, 32), "SFML Graphics");
while(App.IsOpened())
{
sf::Clock Clock;
while (Clock.GetElapsedTime() < 5.f)
{
std::cout << Clock.GetElapsedTime() << std::endl;
sf::Sleep(0.5f);
}
sf::Image image;
sf::Sprite sprite;
if(!image.LoadFromFile("BaronsheetBas1.gif"))
{
}
else
{
sprite.SetImage(image);
}
}
return 0;
}
当我编译时，我一直有这些错误。

时钟工作正常(我单独尝试过)但是当我尝试加载图像然后将其放入 Sprite 时，出现了这些错误。
我已尝试将这些库包含到我的项目中，但错误仍然存在 - sfml-main.lib - sfml-system-s.lib 和 sfml-system-s-d.lib - sfml-graphics-s.lib 和 sfml-graphics-s-d.lib - sfml-window-s.lib 和 sfml-window-s-d.lib
我真的不知道现在该做什么:/
如果你们中的任何人有答案或可以帮助我找到答案，很高兴分享它:)
谢谢!!!
注意:对不起我的英语，这不是我的母语。
最佳答案
如果您链接到 sfml 的静态库(sfml-system-s.lib 等)，请确保在预处理定义中设置了 SFML_STATIC 变量。
在 visual studio 中，您可以在预处理设置(“预处理器定义”)中执行此操作，如下所示:http://sfml-dev.org/tutorials/2.0/start-vc.php
如果你想创建一个在其他没有安装 sfml dll 的机器上运行的游戏，你绝对应该链接到 Windows 上的静态库。
关于c++ - 尝试使用 SFML 时出错(一些 LNK 错误)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/16310435/
