    Qt 5.6 renames signal QProcesss::error()
    
    QProcesss::error() was renamed to QProcesss::errorOccurred().
    
    The renaming was done to avoid confusion from overloading (see the
    documentation for the signal before the renaming [1]).
    
    For more details, see this Qt bug report [2].
