[Quantlib-dev] Problem with abstrat class

[<tar...@li...>]

Hello,

I've added into ql/processes a new class with is the same as 
blackscholesprocess class with a very small change to handle a quanto 
adjustment.
I can build quantlib but when I go to use this class into my project it 
returns me the error
"cannot instantiate abstract class".

any suggestion?

thanks in advance,
regards,
Paolo
