I am not sure what 'adding the line "Gtk::TextView textView;" to my
header' means, but probably you meant that you have defined a global
textview object.  You cannot do that because it will cause the textview
object to be created before main() is entered, which will be before
you have called the Gtk::Main constructor to initialise GTK+.
