[Rcpp-devel] OpenACC, Rcpp and RStudio on Windows (Emmanuel Hamel)

[Dmitriy Selivanov]

Hi Emmanuel. Probably you take a look to the approach taken by Microsoft
in LightGBM R package. I do not know details (so approach could be
irrelevant to what you've asked), but on windows they build package (even
with gpu support) using Visual Studio toolchain. You can check here -
https://github.com/Microsoft/LightGBM/tree/master/R-package.

If you will find it useful please report back to this mailing list, so we
will be aware of it. Thanks.
