Initialization in Audio Applications

Hey all,
I’ve been developing plugins for a while with juce and am now starting an audio application.

Unfortunately I’m always getting a linker error.

This is a blank project, only changes are:

In MainComponent.h

private:
    // Your private member variables go here...
    ScopedPointer<NetworkServiceDiscovery::Advertiser> advertiser;
    JUCE_DECLARE_NON_COPYABLE_WITH_LEAK_DETECTOR (MainComponent)
};

and in MainComponent.cpp:

MainComponent::MainComponent()
{
    // Make sure you set the size of the component after
    // you add any child components.
    setSize (800, 600);
    // specify the number of input and output channels that we want to open
    setAudioChannels (2, 2);
    advertiser = new NetworkServiceDiscovery::Advertiser("1","1",1,1,RelativeTime::seconds(1.5f));

}

Exact same code works in a plugin project. What am I missing?

Cheers

It would be helpful if you included the linker error here.
