CodeBlocks SFML音频库将无法正常工作

标签： c++ audio codeblocks sfml

我一直在关注代码块中的SFML的一些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，我已经尝试从使用.ogg切换到.wav文件并返回到我的代码中，并在一段时间内使用了所有内容，但该程序无法正常工作。我真的不明白这些库是如何工作的（如果不明显的话我是新的）但是我已经查看了sfml的lib文件并在我的链接器设置中包含了每个文件，所以我不明白为什么我继续得到错误。无论如何，我遇到了大量的错误，并希望简单地使用SFML的音频部分。以下是破解案例所需的所有数据：

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:(我已尝试将订单移动一吨左右，但没有帮助）

答案 0 :(得分：0)

未链接音频库。这是未定义的引用错误的含义。因此，您应该检查您的项目文件是否链接到路径中存在的静态lib文件（.a）。

另一件事是你不需要你的链接器设置中的任何库，除了SFML库之外，因为它们已经链接到SFML静态lib文件中。不是真的在2.3中，但在2.1中是真的

答案 1 :(得分：0)

正确的链接顺序是：

openal32
flac
vorbisenc
vorbisfile
vorbis
ogg

不是：

flac
ogg
vorbis
vorbisenc
vorbisfile
openal32

否则它会为您提供对'oggpack _ ***'的未定义引用

答案 2 :(得分：0)

请使用正确的链接顺序：

def to_var(x, volatile=True):
if torch.cuda.is_available():
    x = x.cuda()
return Variable(x, volatile=volatile)

否：

openal32
flac
vorbisenc
vorbisfile
vorbis
ogg

否则，它将为您提供对'oggpack _ ***'的未定义引用
