Question

我试图构建一个使用SDL2的游戏（编译很好，但是在执行二进制文件时我遇到了seg错误）和SFML（我无法成功编译）。

这些是我得到的错误：

代码已于2015年上次更新，因此我假设它使用的是一些较旧的SFML版本（我不知道），在最新版本中，某些功能已更改且兼容性已损坏。我无法测试旧版本，因为只有一个版本可用于RPi3（2.4）。

audio / player.cpp文件：

public:
    sf::SoundBuffer operator()(const std::string& name) {
        std::vector<char> data =

        if(data.empty())

            throw std::logic_error("Cannot load sound \"" + name + "\"");
        return sb;
    }
};

class ControllerImpl : public Controller {
public:
    ControllerImpl(const sf::SoundBuffer& sb, bool autoplay, bool loop) :
        mSound(sb, loop)
    {
        if(autoplay)
            mSound.Play();
    }

    virtual bool IsPlaying() const override {
        return mSound.GetStatus() == sf::Sound::Playing;
    }

private:
    sf::Sound mSound;
};

} // namespace

std::shared_ptr<Controller> Play(const std::string& name, bool autoplay,
                                 bool loop) {
    static Cache<sf::SoundBuffer, Loader> cache;
    const sf::SoundBuffer& sb = cache.Get(name);
    return std::make_shared<ControllerImpl>(sb, autoplay, loop);
}

#else

// SDL audio code, not needed

#endif

} // namespace audio
} // namespace oci
