Error with sourceCpp()

[stanthil]

Hi,

I am looking to use Rcpp11 but running the following lines :

library(Rcpp11)
library(attributes)
sourceCpp('test.cpp', verbose=TRUE)

returns this error :

#include <Rcpp11>

// [[export]]
IntegerVector foo(){  
  return {1, 2, 3} ;
}

// foo (test.cpp:4) - Rcpp::export
extern "C" SEXP sourceCpp_foo(  ){

  BEGIN_RCPP
    SEXP __sexp_result ;
    {
      Rcpp::RNGScope __rngScope;

      IntegerVector __result = foo() ; PROTECT(__sexp_result = Rcpp::wrap(__result)) ;
    }
    UNPROTECT(1) ;
    return __sexp_result ;
  END_RCPP

}

In addition: Warning message:

What might be the problem here ?

attributes::sourceCpp should have given you more text. I get a lot of it mainly related to the fact that the compiler in Rtools 31 does not support C++11 fully.

> attributes::sourceCpp( "foo.cpp", verbose = TRUE )
#include <Rcpp11>
using namespace Rcpp11;

// [[Rcpp::export]]
IntegerVector foo() {
   return {1,2,3};
}

// foo (foo.cpp:4) - Rcpp::export

Not much we can do at this point besides waiting for the toolchain that had been subtly announced to be released with R 3.2.0 in next spring.

e.g.

 error: 'Tuple' does not name a type

is because C++0x does not support the using notation. A lot of error are related to that. Nothing I can really do, as part of Rcpp11 3.1.2.0 we do mean C++11 for real, not pseudo unfinished c++0x

[eddelbuettel]

I noticed this earlier today and did a quick test with Rcpp -- it works on Windows with the old g++.

But as we do not have the new IntegerVector constructor, you need one more step. So here is a slightly expanded example.

#include <Rcpp.h>

// Enable C++11 -- or rather C++0x which is all Windows has
// [[Rcpp::plugins("cpp0x")]]

// [[Rcpp::export]]
Rcpp::IntegerVector foo() {  
  std::vector<int> x = {1, 2, 3};
  return Rcpp::IntegerVector(Rcpp::wrap(x));
}

// [[Rcpp::export]]
std::vector<int> bar() {  
  std::vector<int> x = {1, 2, 3};
  return x;
}

/*** R
foo()
bar()
*/

which works out fine under Windows:

R> library(Rcpp)
R> sourceCpp("C:/TEMP/ghtbStan.cpp")

R> foo()
[1] 1 2 3

R> bar()
[1] 1 2 3
R>

on a system with

R> Sys.info()
                     sysname                      release                      version 
                   "Windows"                      "7 x64" "build 7601, Service Pack 1" 
                    nodename                      machine                        login 
                "DIRK3500W7"                     "x86-64"              "deddelbuettel"

             "deddelbuettel"              "deddelbuettel"

So @eddelbuettel what does this have to do with attributes or Rcpp11 ?

Also your foo and bar are a waste of memory as they imply a deep copy of everything, in wrap for foo and implicitly as returned by bar.

The fact that Rcpp11 only works with C++11 is by design. a feature.

Although I prefer the elegant code as used by @gthbStan, I can also use your less elegant code with Rcpp11, given a real c++11 compiler is used, not some vague c++0x intermediate version. c++0x is not a standard, c++11 is.

$ Rcpp11Script /tmp/dirk.cpp

> foo()
[1] 1 2 3

> bar()
[1] 1 2 3

[eddelbuettel]

I saw the request for help by a user, and had a quick check to see what Rcpp could do.

And after you offered "please wait until April 2015 for R 3.2.0" I considered it to helpful to show what works today -- and what as a matter of fact has worked for years.

[romainfrancois]

How generous of you.

Thanks @romainfrancois and @eddelbuettel for your valuable answers.
