There seems to be a problem using Rcpp::plugins("cpp11") on Windows
8.1. It gives the error:
cc1plus.exe: error: unrecognized command line option '-std=c++11'
I am using Rtools 3.1.0.1942 (which is the latest version) and for
that it needs -std=c++0x or -std=gnu++0x
If I remove the plugins line and instead issue this line first then it
all works (except as per prior email I built Rcpp without vignettes to
get around that problem):
Sys.setenv("PKG_CXXFLAGS"="-std=c++0x") # for gcc 4.6.3
> code <- '
+ // [[Rcpp::plugins("cpp11")]]
+
+ #include <Rcpp.h>
+ #include <boost/range/irange.hpp>
+
+ using boost::irange;
+
+ // [[Rcpp::depends(BH)]]
+
+ // [[Rcpp::export]]
+ int useCpp11() {
+ auto sum(0);
+ for(const auto& i : irange(0,4)) { sum += i; }
+ return sum;
+ }
