[Rcpp-devel] Compilation error

[Mattias Nyström]

Hello,

I've just started with Rcpp. When I compile my file mattias.cpp, using: "R CMD SHLIB mattias.cpp", I get the error below. The source code of the file mattias.cpp is also written below. What can the problem be?

Source code of mattias.cpp:
#include <Rcpp.h>
SEXP firstfunction(SEXP nvec, SEXP ivec, SEXP svec, SEXP nmat)
{
                             SEXP rl=R_NilValue;
                             RcppVector<double> nv(nvec);
                             RcppVector<int> iv(ivec);
                             RcppStringVector sv(svec);
                             RcppMatrix<double> nm(nmat);

                             return rl;
}

The compilation error:
g++ -I"C:/PROGRA~1/R/R-210~1.0/include"        -O2 -Wall  -c mattias.cpp -o mattias.o
