[Rcpp-devel] an error message from RcppArmadillo

Hi there,

I am trying the package of RcppArmadillo. This is the code I copied from
your website. I am not sure what went wrong.

My inline package is 0.3.10, RcppArmadillo is 0.3.6.1, Rcpp is 0.10.2. I
also installed Rtools216.exe. Please let me know what I did wrongly. Thank
you.
