Hi,
The file lives in the lib directory of the installed package Rcpp.
Rscript -e "cat(system.file( 'lib', 'Rcpp.h', package = 'Rcpp' ))"
The maintainer of Rcpp (cc'ed, just in case) will tell you more tricks.
Note that Rcpp has its own mailing list.
https://lists.r-forge.r-project.org/cgi-bin/mailman/listinfo/rcpp-devel
where questions like this might be more appropriate.

Hi,
I am Linux Ubuntu 9.04 user. I'm using R-2.6.
Actually, I am developing R package for reading/writing 3D images. I needed
to use the R package Rcpp in order to make profit of available C/C++ codes.
My problem is that my C code is not able to include the Rcpp.h
In fact, when I run this command R CMD build rply, I got the following error
message in the file /home/amine/R/r-eclipse/rply.Rcheck/00install.out:

** Removing '/home/amine/R/r-eclipse/rply.Rcheck/rply'
It is evident that I will this error since the file Rcpp.h is not in this
directory /usr/share/R/include .
I tried to solve this include problem by copying the Rcpp.h to
/usr/share/R/include. But, it was not successful and I the following error
message.
Error in dyn.load(file, DLLpath = DLLpath, ...) :
Unable to load shared library
'/home/amine/R/r-eclipse/rply.Rcheck/rply/libs/rply.so':

Error in library(rply) : .First.lib has failed for 'rply'
Execution stopped
It looks like this package has a loading problem: see the messages for
details.
Resulting this last error seems to be also logical. In fact, I think the
file libRcpp.so is need for the compilation of my code.
Please notice that the package Rcpp is installed in the following directory:
/usr/lib/R/site-library/Rcpp
Thank you for giving an idea for solving this problem.
