The idea > of putting SystemRequirements: C++ in the DESCRIPTION file was to A question here, though: I thought that by using "SystemRequirements: C++11" we make it easy for the user to know that (e.g., it is explicitly shown by both CRAN's and BioConductor's information about a package). But commenting that out, it is no longer explicit (but then, maybe it is not that big a deal). > provide a shortcut for packages that have no Makevars file. From your Aha, I see. I think I removed the Makevars file after Rcpp 0.11 was released. I just added a src/Makevars file, and following Dirk's response I also added entries in .R/Makevars for CXX1XSTD CXX1XFLAGS and these, as well as possible entries for CC CXX CXX1X all are now followed. > description, it sounds like this shortcut has the unintended consequence > of overriding the user's Makevars file. > > I will look into it, but you can make this task a lot easier by telling > me which packages using C++11 are affected and give me some examples of > specific Makevars entries that are ignored. > This is a BioConductor package: http://www.bioconductor.org/packages/devel/bioc/html/OncoSimulR.html (the version right now at bioc fails in Windows and Mac but that should be fixed). with github repo here: https://github.com/rdiaz02/OncoSimul I can of course send you the tar.gz with the latest sources that build OK with both gcc and clang. Makevars entries ignored: things such as: CC=clang CXX=clang++-libc++ CXXFLAGS= -g -O3 -Wall -Wextra -pedantic Best, R. > Martyn > > On Fri, 2015-06-19 at 12:01 +0200, Ramon Diaz-Uriarte wrote: >> Dear All, >> >> Some of my packages use >> >> SystemRequirements: C++11 >> >> in the DESCRIPTION.
