[ROOT] how to run TMINUIT from a stand alone c++ class?

Dear Rooters,

I'm trying to call TMinuit from a c++ class in a similar way
that I've used TMinuit in a program called directly from 
ROOT, but now I do not  know how to define the 'fcn' 
function in order for TMinuit to recognice it with the 
	SetFCN(fcn)
I've tried many different ways (attached is a small example)
but my code does not want to compile. Could anyone help me how 
to change this so that the attached code goes through the compilation?

Thanks!!!
