[Rcpp-devel] rcpp 0.10 on mac error with sourceCpp

[Jiqiang Guo]

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")));
}
