[Rcpp-devel] Compilation ERROR

[Sedat Sen]

Dear list,

I am planning to use Stan through R which requires using Rcpp package and
C++ compiler. I am not familiar with C++. I have been trying to install
necessary packages and tools. I followed the steps given at this website:
http://tonybreyal.wordpress.com/2011/12/07/installing-rcpp-on-windows-7-for-r-and-c-integration/

There is an example code on that website. I tried to run it many times. I
failed at each attempts. I have spent hours and googled but could not get
it run. Could you please help me solve this problem based on the code and
error below.

# install packages
install.packages(c("Rcpp", "rbenchmark", "inline", "RUnit"))

# load main two packages
library(Rcpp)
library(inline)

# do something with Rcpp to quickly check that it works
body <- '
NumericVector xx(x);
return wrap( std::accumulate( xx.begin(), xx.end(), 0.0));'

add <- cxxfunction(signature(x = "numeric"), body, plugin = "Rcpp")

*ERROR:*

I am using Windows-64 bit. On my previous run, I also got an error
like *"Cygwin1.dll
Not Found". *In order to fix this I reinstalled the Cygwin but it did not
work. Now I am getting the long error listed above.


I am also adding what seems on my PATH
C:\R\batchfiles_0.6-6;C:\R\Rtools\bin;C:\R\Rtools\MinGW\bin;C:\cygwin\bin


Any suggestion?
