I have Visual Studio 2015 on my windows 10 and I would like to use Rcpp for developping my own package. Now I get an error "status 127" which means, according to this SO post, that the C++ compiler is not found. I don't want to install RTools because I think I have already a C++ compiler since Visual studio can make it (see also).

Now my problem is : how to locate this compiler and how to point R onto it ? This post should help me but I cannot figure out how to properly follow it.

There may also be some good references here about R PATH and here for C++ and Visual Studio. I recognize I don't understand a lot of things about these config pages.

thanks

    Please see [question 2.9 of the Rcpp FAQ](https://cloud.r-project.org/web/packages/Rcpp/vignettes/Rcpp-FAQ.pdf). – Dirk Eddelbuettel May 31 '17 at 14:23
  • Thanks for pointing out. Indeed I am scared of installing RTools because of possible interference with the current c++ compiler. But so there is no such risk indeed ? – ClementWalter May 31 '17 at 14:46
