[Rcpp-devel] Building RcppBDT fails on Win 7 64-bit

[Dino Veritas]

Hello Rcpp-devel community,

I am trying to build the RcppBDT package on Windows 7 64-bit using the
latest version of Rtools. This version of Rtools comes with gcc-4.6.3.
The process fails when building the 64-bit library for RcppBDT,
complaining about an invalid conversion from 'SEXP' to 'long long int'
somewhere in the Rcpp headers.

I built Rcpp as well as the RcppExamples package with no problem using
this toolchain. I am using the latest revisions of Rcpp and RcppBDT
(rev 4600).

Is it possible to build a 64-bit version of RcppBDT on Windows? If so,
what do I need to do to make this happen? Do I have to look into using
a separate newer version of gcc to build Rcpp packages? This package
is for internal use only and will not be published on CRAN or anything
so I don't care if I fail certain CRAN checks.

Thank you kindly,
Dino
