Trying to call functions from other classes

Question

I'm trying to get FMOD working but I just can't get the main() to call it

int main()
{
  cout << "Using FMOD \n";
  cout << "Select a Track: 1-5 Horror \n";
  cin >> HorrorTrack;

  AudioProject *pAudioProject = new AudioProject;
  pAudioProject->initAudio();
  //AudioProject::initAudio();
  MainPage(); // Main Page Function

  if (pAudioProject)
  {
      delete pAudioProject;
      pAudioProject=NULL;
  }

  char f;
  cin>>f; 
  return 0;
}

The errors I'm getting are:

unresolved external symbol "public: __thiscall AudioProject::AudioProject(void)" (??0AudioProject@@QAE@XZ) referenced in function _main

1>C:\\Users\\CodeMonkey\\Desktop\\AudioProject\\Debug\\AudioProject.exe : fatal error LNK1120: 1 unresolved externals.

Which is from the .h file variables which are declared public . However, if I make the initAudio anything but public I wont be able to access it in my main() function. Any ideas?

You haven't linked the library, so the definitions of symbols that it exports cannot be found.

Read this "FMOD"'s instructions.
