I am running into a wall getting my system to work with rcpp and inline. 
Following Dirk's advice on stackoverflow, I hope someone is able to help 
me.

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

I am trying to get the following code to work:

library(Rcpp)
library(inline)

body <- '
NumericVector xx(x);
return wrap( std::accumulate( xx.begin(), xx.end(), 0.0));'

add <- cxxfunction(signature(x = "numeric"), body, plugin = "Rcpp", 
verbose=T)

x <- 1
y <- 2
res <- add(c(x, y))
res


I get the following error messages:

  >>  setting environment variables:
PKG_LIBS =  C:/Users/Owe/Documents/R/win-library/2.15/Rcpp/lib/x64/libRcpp.a

  >>  LinkingTo : Rcpp
