1) Your email does not state how you invoke g++ (or R, which invokes it for you)
2) Your email is not complete as it has no reproducible code
3) Your email refers to a working examples _which still works_ (see below)
4) All you need to know is spelled out in the Rcpp documentation. I am not
going to repeat it here. See eg the two chapters on 'compiler etc setup' and
RcppGSL in my Rcpp book.
