Well, OK, but that doesn't work for DWARF, and everybody these days should be using DWARF. Actually I would like that option to work for DWARF but nobody has implemented it. >> Note that in general you need to have a variable of type X before gdb >> can tell you anything about it. >> > Actually I have one, but I don't need to. > Gdb must be able to display class members without a variable of this class. But gcc won't generate debugging information for a class if there are no actual instances of the class. Otherwise C++ .o files would be gargantuan, since they would have to contain debug info for every class defined in every included .h file. Ian
