[Rcpp-devel] Rcpp C++11 on Windows

[Peter Meissner]

Hey Listeners,

I am quite solid in R but a complete noob to C++ and Rcpp so please excuse  
if do not get it right ...

My problem is that I would like to have a package using Rcpp AND using  
C++11 features AND working on both Linux (Debian derivates) and Windows.  
For Linux I seem to be on the right track and features like 'auto' and  
'iterators' do work. On Windows however it will not compile.

As far as I understand it, the main problem is that Rtools comes with a  
compiler that simply does not support those features (g++ version 4.6.3).  
Furthermore, I found that C++11 features are not CRAN compatible - right?

Do I get it right so far? Can you give guidance on how best to proceed?  
Should I get a newer g++/or-other compiler and make it the system default?  
What are best or good working practices? Windows/Linux is a must and  
system tweaks for other Windows users installing/building the package  
should be minimal, though CRAN compliance would be only a minor extra.

I hope I did not miss some obvious documentation or already existing  
I-take-you-by-the-hand-blog-post.


Best, Peter
