  Hi rooters,

  I would like to define one class "A", parent of another class
"B", the child. I'm trying to do it definning "A" as child of
TObject, because I want to link all together in a single
executable program. But I get all the time errors of the
following type:

Unresolved:
__vtbl_1a  Make sure that the first noninlined virtual member
function of 'a' is
 defined.
__vtbl_1b  Make sure that the first noninlined virtual member
function of 'b' is
 defined.

I cannot find in the documentation how to handle this problem. Do
you have any idea?

Thanks,

  J C
