Re: Function not definen in current scope

Through all CINT errors it appears I'd forgotten that it could also be my fault. Well, it now knows the function but the result is still not satisfying. Now it does not accept >> on istringstream. I give up on this and will try to compile it as a library. Thanks.

Error: operator>> not defined for basic_istringstream
