[R-pkg-devel] CXX14 not defined on Windows
I am testing building a package on Windows. The package requires C++14. I have installed the latest versions of R (3.6.2), RTools (3.5), and RStudio. The package builds fine under Linux. I get the following error: > devtools::install_github("gdkrmr/zarr-R") ... C++14 standard requested but CXX14 is not defined ... I have also set `~/.R/Makevars.win` as suggested in the manual "Writing R extensions", Section 1.2.5 "Using C++14 code". When typing `R CMD config CXX14` in the RStudio terminal, I get a reply ("c:/Rtools/mingw_64/bin/g++"). When trying to install the package manually with `R CMD INSTALL ...` from the RStudio terminal, I get the same error. What am I doing wrong? Thanks!

What exactly do you have in src/Makevars.win? Just the simple CXX_STD = CXX14 or the more complex set-up from the end of section 1.2.5.. The rstan package is on CRAN including windows binaries and uses C++14. In src/Makevars.win they have CXX_STD = CXX14 CXX14STD = -std=c++1y c.f. https://github.com/stan-dev/rstan/blob/40e93534e771d8c536ddb60fc62e86a5b55596de/rstan/rstan/src/Makevars.win#L2-L3 cheerio ralf __ R-package-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-package-devel

I think I also noticed at least one other package using C++14 with the current toolchain (xtensor) and it used eg by one other package (rray) which has an even simpler src/Makevars.win just setting CXX_STD as advised (plus tweaks to PKG_CXXFLAGS, see https://github.com/r-lib/rray/blob/master/src/Makevars.win So notwithstanding my earlier message Guido's package should work with the current Rtools.

Re: [R-pkg-devel] CXX14 not defined on Windows
I have used the same setup as in Section 1.2.5 of the manual and have set CXX_STD=CXX14 in src/Makevars.win. No I also remember that, when I sent the package to winbuilder, some time ago, it started compiling (the compile failed, but at least it tried).

Re: [R-pkg-devel] CXX14 not defined on Windows
I had some success using RTools40 and the corresponding R testing version. I had to do a lot of MSYS shenanigans and couldn't get static compilation to work, but the binary package seems to work just fine in R 3.6.2. It makes me very happy to see that R will get an updated toolchain and a proper MSYS environment with a package manager! Is there a due date for R 4.0.0?
