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. | My steps were to install MinGW 32 bit first, then installing Rtools, I | disabled MinGW's entry in the PATH.

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.
