      I suddenly started getting some strange errors while compiling the code.
      i have not modified any files from these locations.

      for a while it was working perfect, and i observed these suddenly, i could not rectify the problem.
      now even if i open a new project and write @qDebug() <<"hello";@ also it is giving these errors.
      i cut few lines because of no of lines constraint .
