need help with program crashing/undefined symbol..

[drarem]

Using QT and trying to use SFML audio, I get this when trying to run my program:

symbol lookup error: /usr/local/lib/libsfml-audio.so.1.6: undefined symbol: _ZTIN2sf6ThreadE
exited with code 127

I'm using the following setup/test:

INCLUDEPATH += /usr/include/SFML
LIBS += -lsfml-window -lsfml-graphics -lsfml-system -lsfml-audio -lsfml-network

    sf::SoundBuffer Buffer;
    if (!Buffer.LoadFromFile("bounce.ogg"))
        exit(1);

    unsigned int SampleRate = Buffer.GetSampleRate();
    unsigned int Channels   = Buffer.GetChannelsCount();

    // Create a sound instance and play it
    sf::Sound Sound(Buffer);
    Sound.Play();

How did you install SFML?

Do you have (or did you have) several versions installed?

Installed via packing and ubuntu 12.04

In fact the answer to this problem is explained in the gcc tutorial. So I let you read it carefully
