[Rcpp-devel] RcppProgress RcppArmadillo

[bbonit at tin.it]

 Dear list good morning,
 can someone explain why the compiler return me an error when I add the following include 
#include <progress.hpp> (without this inclusion the code is compiled in correct way)
(using // [[Rcpp::depends(Rcpp,RcppArmadillo,RcppProgress)]] for dependencies)

the example code (using attributes sourceCpp) :


// [[Rcpp::depends(Rcpp,RcppArmadillo,RcppProgress)]]

#include <RcppArmadillo.h>
#include <RcppArmadilloExtensions/sample.h>

#include <progress.hpp>


// [[Rcpp::export]]

arma::vec Mahalanobis(arma::mat x, arma::rowvec center, arma::mat cov){
    int n = x.n_rows;
    arma::mat x_cen;
    x_cen.copy_size(x);
    for (int i=0; i < n; i++) {
        x_cen.row(i) = x.row(i) - center;
    }
    return sum((x_cen * cov.i()) % x_cen, 1);    
}


require("Rcpp")
Sys.setenv("PKG_CXXFLAGS"="-fopenmp")
Sys.setenv("PKG_LIBS"="-fopenmp")
 sourceCpp("rr.cpp")


ERROR :
