【问题描述】：

我一直在关注一些关于代码块中 SFML 的 youtube 教程，我们刚刚接触到音频。到目前为止，我只使用了图形方面，但没有任何问题。虽然对于音频，我尝试从使用 .ogg 文件切换到 .wav 文件并返回到我的代码中，并且玩了一段时间，但程序无法正常工作。我真的不明白这些库是如何工作的（如果这不明显，我是新手）但我已经查看了 sfml 的 lib 文件并将每个文件都放在我的链接器设置中，所以我不明白为什么我继续得到错误。无论如何，我遇到了大量错误，并想简单地使用 SFML 的音频部分。以下是破案所需的所有数据：

实际代码：

#include <SFML/Graphics.hpp>
#include <SFML/Audio.hpp>
#include <string>
#include <iostream>

int main(){

    sf::Vector2i screenDimensions(800,600);

    sf::RenderWindow Window;
    Window.create(sf::VideoMode(screenDimensions.x, screenDimensions.y), "A Window");

    sf::Clock clock;

    sf::SoundBuffer soundBuffer;
    sf::Sound sound;

    if(!soundBuffer.loadFromFile("punch.ogg")){
        std::cout << "Can't find audio file" << std::endl;
    }

    sound.setBuffer(soundBuffer);

    float moveSpeed = 10000.0f;

    while(Window.isOpen()){

        clock.restart();
        sf::Event Event;
        while(Window.pollEvent(Event)){

            switch(Event.type){
            case sf::Event::Closed:
                Window.close();
                break;
            case sf::Event::KeyPressed:
                if(Event.key.code == sf::Keyboard::Escape){
                    Window.close();
                }
                if(Event.key.code == sf::Keyboard::P){
                    sound.play();
                }
                break;
            }
        }

        Window.display();
        Window.clear();
        }
}

链接器设置：（我尝试将订单移动一吨左右，但没有帮助）

【解决方案1】：

音频库未链接到。这就是未定义的引用错误的含义。所以你可能应该检查你的项目文件是否链接到你的路径中存在的静态库文件（.a）。

~~另一件事是，除了 SFML 库之外，您不需要当前在链接器设置中拥有的任何库，因为它们已经链接到 SFML 静态库文件中。~~ 不正确在 2.3 中，但在 2.1 中是正确的

【讨论】：

这绝对不是真的。静态链接 SFML 时，您必须链接 SFML 依赖项。
@Alayric 阅读手册。您只需链接到 .a 文件。至少使用 -s.a 文件。对于音频，您需要确保可执行文件在 dll 用于 sndfile 和 openal 的同一目录中启动
official tutorial 中的红色：“静态链接时，您还必须将 SFML 的所有依赖项也链接到您的项目”
@Alyric 我记得不必在 2.1 上链接 SFML 的部门。所以如果是2.3我可能会错，因为我没有使用过。
@Alayric 我使用的 SFML 的最后一个版本是 2.1 不是这种情况，所以我错了。

【解决方案2】：

正确的链接顺序是：

openal32
flac
vorbisenc
vorbisfile
vorbis
ogg

不是：

flac
ogg
vorbis
vorbisenc
vorbisfile
openal32

否则它会给你未定义的'oggpack_***'引用

【解决方案3】：

请使用正确的链接顺序：

openal32
flac
vorbisenc
vorbisfile
vorbis
ogg

不是：

flac
ogg
vorbis
vorbisenc
vorbisfile
openal32

否则它会给你未定义的'oggpack_***'引用
