[Rcpp-devel] R.e. A RcppArmadillo based program cannot compile under Windows and RStudio

Wed Mar 11 23:25:41 CET 2015

No problem.
One more piece of list etiquette: when writing follow-up emails,
please CC the list in your response to individuals who have directly
answered you.  This prevents questions from being (privately) answered
repeatedly.

Two questions:

* Can you confirm that you do, in fact, have RcppArmadillo installed
by a call to library(RcppArmadillo)?

* You've looked over the Rcpp FAQ carefully?  Compilation on windows
is, er, different.

I don't have a windows machine, so I'm not able to reproduce your
problem.  Perhaps someone else can use the detailed information that
you've provided to identify the problem with your included example.

Best,
Christian
