I tried the example of sourceCpp on Mac mountain lion with R 2.15.1
with the following error (I hit the similar error in using RStan as
well).
> library(Rcpp)
> require(Rcpp)
>
> sourceCpp(code='
+ #include <Rcpp.h>
+
+ // [[Rcpp::export]]
+ int fibonacci(const int x) {
+ if (x == 0) return(0);
+ if (x == 1) return(1);
+ return (fibonacci(x - 1)) + fibonacci(x - 2);
+ }'
+ , verbose = TRUE)
Generated Rcpp module declaration:
--------------------------------------------------------
RCPP_MODULE(sourceCpp_72196) {
Rcpp::function("fibonacci", &fibonacci,
Rcpp::List::create(Rcpp::Named("x")));
