Correct -- the RInside package comes with four example directories. And each of these four directories has a Makefile. The easiest to start with is examples/standard/Makefile as you can simply drop in a new file 'myhelloworld.cpp' (or any other name you choose) into this directory and say 'make myhelloworld' --- and the binary 'myhelloworld' will be created for you. It does this by querying R via Rscript to learn about headers and libraries for R headers and libraries for Rcpp headers and libraries for RInside and all six components are needed for compiling and linking.
