[Rcpp-devel] Compilation ERROR

By default, g++.exe is installed into <Rtools_path>/gcc-<version>/bin; and
you want to make sure that folder is in your path (not just
C:\R\Rtools\bin, so I guess in your case, assuming an up-to-date version of
R/Rtools, you want to make sure C:\R\tools\gcc-4.6.3\bin is also in your
path). Note that this is done by default with the Windows installer (it
sets the system path rather than the user path). Also, ensure that you have
a version of Rtools compatible with the version of R you're using. Finally,
make sure you don't have any other (older?) versions of gcc or g++ hiding
in a path that's included before the Rtools path. If those versions are
getting called rather than the Rtools g++, that could lead to this problem.

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")

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?
