You are not telling g++ where to find the R libraries that you need to
link with.

I've a similar basic RInside example and I've got a comment in the
header that says compile it with this:

g++ -I/usr/local/lib/R/site-library/Rcpp/include
-I/usr/local/lib/R/site-library/RInside/include -I/usr/share/R/include
-L/usr/lib64/R/lib -lR -L/usr/local/lib/R/site-library/Rcpp/lib -lRcpp
-L/usr/local/lib/R/site-library/RInside/lib -lRInside
-Wl,-rpath,/usr/local/lib/R/site-library/Rcpp/lib -lRInside
-Wl,-rpath,/usr/local/lib/R/site-library/RInside/lib main.cpp


You may have to adjust the paths (I'm on ubuntu 10.04, and I think
default locations for all R packages), but it gives you an idea of what
you're missing.

P.S. In that same directory I've also a rather long Makefile that
describes itself as a "simple Makefile". It doesn't look like I wrote
it; I guess it is from the RInside examples or vignette.
