[comp.sys.next] Help with adding to a class

shiffman@sumex-aim.stanford.edu (Smadar Shiffman) (06/01/90)

I'm trying to add a method to the Object class by defining a category for the
class. I can't get the other objects in my application to inherit the method.
At run time when the added method is sent to an object I get an error message:
"Unable to find method implementation".
I also noted that in GDB, after typing 'info selector method' I get:

All selectors matching 'method':
 mapped selector #3 = 'method'
..defined by: ???


Any hints?
	Thanks,
