error linking shared library

I just tried linking in a shared library to root, using the directions and
files as described in the "Extending ROOT with Shared Libraries and an Example
of Object I/O" tutorial #44. I'm able to make the library with no problems, but
when I try to load it into root with "gSystem.Load("event.sl")", I get the
error message:

dlopen error: ./event.sl: undefined symbol: __tf7TObject
Load Error: Dynamic link library ./event.sl can not load
(int)(-1)

I'm running on a linux box, using v2.21/08 of root. I've tried it with
older versions of root, and gotten the same error.

Can anyone help me with this?

thanks... Charles.
