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")
