[Rcpp-devel] Rcpp release candidate

I am using  "R version 3.1.0 Patched (2014-05-09 r65562)" but its
working now so perhaps you changed more than described.

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:

Does that work for you? You can install with:

devtools::install_github("RcppCore/Rcpp", ref = "feature/windows-c++0x")

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. Of those 18 a number where due
to
package sirt not building because ... I use FC='ccache gfortran' which
is not
gfortran so its configure failed. Grrr. I would pass next time.

Anyway, 195 packages passed just fine, so we should be good.  But if
there is
something anyone of you would like to test, now would be a good time as
I may
upload the current version to CRAN in the next few days unless I hear
objections.

There seems to be a problem using Rcpp::plugins("cpp11") on Windows
8.1.  It gives the error:
cc1plus.exe: error: unrecognized command line option '-std=c++11'

I am using Rtools 3.1.0.1942 (which is the latest version) and for
that it needs -std=c++0x or -std=gnu++0x

If I remove the plugins line and instead issue this line first then it
all works (except as per prior email I built Rcpp without vignettes to
get around that problem):
Sys.setenv("PKG_CXXFLAGS"="-std=c++0x") # for gcc 4.6.3
