linking error

[pradeep]

hi,
I am getting the following error when compiling my c++ program using
g++3.2
Thanks for any help.

In function `TreeNode::Tree Node[in-charge](QListView*, QString
const&, Indic::Node*)':
..obj/tree_gui.o(.tex t+0x173): undefined reference to `vtable for
TreeNode'

I have a simple class TreeNode and pointer of the same class in the
class

thanks
pradeep

Isn't it obvious? You have a bug on line 42.

This error message suggests that the virtual method table of the class
TreeNode was not generated by the compiler. It happens when the first
non-inline virtual member function is not defined (implemented). So
check if it is the case in your code.
