Which Rcpp version do you have installed? Which Armadillo version do you have installed? I have not tried the free-floating direct compile you try here. Maybe the defines for RcppArmadillo that we use are missing here -- hard to say. Could you try to create your own little package but copying the RcppArmadillo files, changes DESCRIPTION to what you do and changes the FastLM code in C++ and R?
