Rcpp::depends(BH) #19

Closed romainfrancois closed 10 years ago

romainfrancois commented 10 years ago 
#include <Rcpp.h>
#include <boost/range/irange.hpp>

// [[Rcpp::depends(BH)]]

// [[Rcpp::export]]
int useCpp11() {
    auto sum = 0;
    for(auto i : boost::irange(0,4)) { sum += i; }
    return sum;
}

produces:

Just in case anybody gets here via Google looking for Rcpp and BH: it does of course work as expected with the Rcpp package (though Boost / BH generates many warning unless -Wno-unsued-local-typedefs is added).
