unsure where you see the confusion between long int and int.

Are you sure?

Problem with R_registerRoutines
...ckage to freshly generated packages by Rcpp.package.skeleton() and RcppArmadillo.package.skeleton().
(Since I had old-ish version of R and Rdevel, I updated them too. )
I believe that you also need to import something from Rcpp (but not from RcppArmadillo). Try the following line
importFrom(Rcpp, evalCpp)
in NAMESPACE (I believe that it is generated by both, Rcpp.package.skeleton() and RcppArmadillo.package.skeleton()).
The path issue on Windows is a separate one. I typically start a command window from a batch file which sets the paths and environment variables maybe more defensively, and the...

...and can also be adapted to other C++ types and libraries as described
in the Rcpp-extending vignette.
Rcpp attributes and their supporting functions include:
- Rcpp::export attribute to export a C++ function to R
- sourceCpp function to source exported functions from a file
- cppFunction and evalCpp functions for inline declarations and execution
- Rcpp::depends attribute for specifying additional build dependencies
