You have not shown a reproducible error in Rcpp. What you have shown is that
you failed to build something using Eclipse.  Which may be well a setup error
on your part.

We support an R package which is fairly rigorously tested and which supports
'R CMD INSTALL .....' for various values of '.....' (and various different
incantations, including RStudio which tries hard (and successfully) to behave
just like R by invoking R as R).

For everything else, you are mostly on your own. Windows is twice as hard
because of its inconsistent $PATH etc. 

I would try to build something simple first, either directly with R or via
RStudio, so that you know that the code works, and then migrate a known
working setup to your chosen environment.

Good luck,  Dirk
