There is a dedicated mailing list for Rcpp: rcpp-devel.

Please let us try to continue the discussion over there. Subscription is required as on some other R lists, so please subscribe before posting.

In general, you need Rtools correctly set up. If and when you compile a basic R package (also containing C or C++ files) from sources, you should be fine.

A decent 60+ page tutorial is available at:

  http://howtomakeanrpackage.pbworks.com/f/How_To_Make_An_R_Package-v1.14-01-11-10.pdf  

Once you have that sorted out, working with Rcpp and inline should "just work" as it does on other operating systems.

What do you mean by "MinGW's path entry disabled" ? You need mingw.

Looks like compilation worked.

That is just noise and can be ignored.

Linking failed. Something is wrong with your static Rcpp library. I cannot tell why this fails.

You could check your package by submitting it to http://win-builder.r-project.org. If it builds there, your local setup is wrong. If it fails there, your package is wrong.  

Cheers, Dirk
