getting a link error  with the message below. After researching the error it
seems like there would be a virtual class definitions lacking. After reviewing 
the code I could not find anything apparently wrong. Any suggestions? Thank you

Well, I have figured out how to compile it:
 diff --git a/QtGlSliceView.cxx b/QtGlSliceView.cxx
 index c218804..65bae97 100644
 --- a/QtGlSliceView.cxx
 +++ b/QtGlSliceView.cxx

 -#include "QtGlSliceView.h"
 +#include "QtGlSliceView.moc"
  #include "itkMinimumMaximumImageCalculator.h"
  #include <QMouseEvent>
  #include <QKeyEvent>

But it segfaults when an attempt is made to run it:
(gdb) run

Done!
