After running edyuk-debug I am not able to find the run.log anywhere.
I have diffed the edyukappliation with it's original as below, is it some thing else I am missing?

Qt Code: 
  1. C:\qtwork\edyuk-0.9.1\src\lib>diff edyukapplication.cpp edyukapplication.cpp.ORG
  2. 75c75
  3. < static QTextStream cout(stdout), cerr(stderr), clog;
  4. ---
  5. > //static QTextStream cout(stdout), cerr(stderr), clog;
  6. 93c93
  7. <       clog << type[t] << msg << endl;
  8. ---
  9. >       //clog << type[t] << msg << endl;
  10. 98c98
  11. <               clog << "aborting..." << endl;
  12. ---
  13. >               //clog << "aborting..." << endl;
  14. 142c142
  15. <       clog.setDevice(pEdyukLogFile);
  16. ---
  17. >       //clog.setDevice(pEdyukLogFile);

BTW the debug edyuk justs shows up in task manager and no GUI comes up, then terminates after a few seconds. Any Idea?
Just set the debug options as you mentioned i.e.:
CONFIG += debug and
add Q_OBJECT to QMakeParser declaration in src/default/qmakemodel/qmakeparser.h
