[Rcpp-devel] Rcpp C++ code debug / Calling Rcpp in a C++ environment

[Jing Peng]

Hi All,

I am trying to debug the C++ code of an R package in a pure C++
environment. That way, I can put aside the interaction between R and C++.

However, I found I was not able to setup Rcpp properly after two days of
effort. I followed the following instructions for Eclipse and Netbeans,
respectively.

Eclipse:

Netbeans:
http://cdrv.wordpress.com/2012/11/12/setting-up-netbeans-to-work-with-rcpp-and-compiling-rcpp-code-for-beginners/

Test code:

#include <iostream>
#include <Rcpp.h>
using namespace std;
using namespace Rcpp;
int main(int argc, char** argv) {
    cout<<"Hello World!"<<endl;
    CharacterVector x = CharacterVector::create( "foo", "bar" ); // problem
occurs here
    cout<<"Done!"<<endl;
    return 0;
}

Platform: Windows 7 x64

I was able to build the code successfully in both Eclipse and Netbeans.
However, I can only see "Hello world" but not "done" from the console
output.

It seems that a problem occurred while calling the Rcpp function
CharacterVector::create, regardless of whether I had linked to Rcpp.dll.

Does anyone has any idea what's happening here, or any idea on how to
effectively debug the C++ code for an R package within an C++ IDE? I
 actually had no problem calling the package in RStudio.

Thanks!
Jing
