You should jump straight to making a package. You are making you life
difficult with this "main program & makefile" model.
Install Rcpp and try to use the Rcpp.package.skeleton, this will create
a simple package that uses some C++ classes from Rcpp, as well as an R
function that calls them.
I read Rcpp , I am not sure if RcppResultSet can solve my problem or other
function. Once I make sure it work I need ask UNIX adminstrator to install it.
We don't know what your problem is. We can answer a question, but we
cannot guess the question for you.
Rcpp works, please refer to our unit tests, for example look at this
vignette:
http://cran.r-project.org/web/packages/Rcpp/vignettes/Rcpp-unitTests.pdf
I think it shouldn't be very complex, as I know to build a R function easy
with one C function.
Thanks you for yout attention!

When you asked _that exact same question_ this morning on r-help, you got the
following answer:

Pick up Rcpp, make your life easier.

Now, can you let us know
a) what part of the answer was unclear to you, and
b) what made you think you needed to repost _the identical question_ here
| Thank you in advance!
You're welcome.
