What version of Rcpp are you using? With R 4.3 and Rcpp 1.0.10 I have no issues.
library(Rcpp)
Rcpp::sourceCpp(code='
#include <Rcpp.h>
using namespace Rcpp;
// [[Rcpp::export()]]
SEXP cpptest(NumericVector v) {
return v;
}'
)
cpptest(1:5)
#> [1] 1 2 3 4 5

Subject: [Rcpp-devel] Rcpp::sourceCpp Problem with R 4.3 update
Looks like the recent update to R 4.3 broke Rcpp::sourceCpp.
Here is a simple example...
library(Rcpp)
Rcpp::sourceCpp(code='
#include <Rcpp.h>
using namespace Rcpp;
// [[Rcpp::export()]]
SEXP cpptest(NumericVector v) {
return v;
}'
)
cpptest(1:5)
This works without problems under R 4.2.3, but under R 4.3 I get...
using C++ compiler: 'G__~1.EXE (GCC) 12.2.0'
