大神看过来，关于linux 下 SFML 库audio播放音乐 的使用

[李苏珂]

第一次写c++ SFML库sfml-audio的实例，然而报错了

#include <SFML/Audio.hpp>

int main(int argc, char const *argv[])
{

sf::Music music;

if (!music.openFromFile("/usr/share/doc/fmodex/examples/media/stereo.ogg"))
{
return -1;
}

music.setVolume(50);
music.play();
music.setLoop(true);
return 0;
}

g++ test.cpp -lsfml-system -lsfml-audio
./a.out
然而报错
