Package building in R with Rcpp -- failure to build a package

I am very new to building packages in R, but I am trying to build a package of already written cpp code to use it in a foreach code, as I am running my code on a Windows machine and I can't pass the cpp code to the nodes.

The cpp code I am trying to wrap in an R package comes from:

https://github.com/darinchristensen/conley-se

I am following the instructions from this website to build the package:

http://web.mit.edu/insong/www/pdf/rpackage_instructions.pdf

Here is the code I am using:

setwd("C:/Users/Tim/Documents/code/")
library(Rcpp)
library(RcppArmadillo)
RcppArmadillo.package.skeleton("itirun")

Then, I try

setwd("C:/Users/Tim/Documents/code/itirun/")
compileAttributes(verbose=TRUE)

And then in terminal I go to the directory, and run the following command which gives me the following error message. I am a newbie at building packages, and I fail to understand what I am doing wrong. I also tried adding compiler flags, but wasn't successful which is probably due to my lack of understanding:
