I couldn't reproduce this on Windows 7 with R 3.1 (which should have been using USE_CXX1X="yes" under the hood resulting in -std=c++0x passed to gcc).
However, I have this change which should make the cpp11 plugin automatically pass -std=c++0x when on R <= 3.0: https://github.com/RcppCore/Rcpp/pull/148 Does that work for you? You can install with: devtools::install_github("RcppCore/Rcpp", ref = "feature/windows-c++0x") On Thu, Jun 5, 2014 at 3:36 AM, Gabor Grothendieck <ggrothendi...@gmail.com> wrote: > On Wed, Jun 4, 2014 at 11:21 PM, Dirk Eddelbuettel <e...@debian.org> wrote: > > > > Rcpp 0.11.2 should be ready. > > > > If anybody wants to jump in and do last minute testing, please do so now. > > > > I ran two complete tests against CRAN last weekend, the results are > > summarized as usual in the GitHub repo at > > > > https://github.com/RcppCore/rcpp-logs > > > > Of 215 CRAN packages, all but 18 passed.
