[Rcpp-devel] installing Rcpp on windows

[Jeffrey Pollock]

Hello,

I'm trying to get Rcpp to work on my machine running Windows 7 64 bit but
I'm not having much luck!

I've reinstalled R in: C:\opt\R-2.13.1
and have: C:\Rtools\MinGW64
my path variables are set as:
C:\Rtools\bin;C:\Rtools\perl\bin;C:\Rtools\MinGW64\bin;C:\opt\R-2.13.1\bin\x64;C:\Program
Files\Java\jdk1.6.0_25\bin;C:\Program
Files\TortoiseSVN\bin;%JAVA_HOME%\bin;%MAVEN_HOME%\bin

Trying some examples from the help pdf I get the following error, can anyone
help?

+ for(inti=0;i<n_xa;i++)
