hey,
so i found this,
https://cran.r-project.org/web/checks/check_flavors.html#r-devel-macos-x86_64-clang
this lists the configuration for CRAN checks as:
Apple LLVM version 5.1 (clang-503.0.38) (based on LLVM 3.4svn), gfortran
4.8.2
which is probably the versions used by CRAN for builds.
just posting this in case others are interested in what build
configuration CRAN possibly uses.
cheers

hi folks,
i'm wanting to configure my macOS system so that it builds R packages
using the same versions of the build tools as CRAN. my motivation is
that i use some packages which make use of Rcpp, and i'd like my
builds of them to be compatible with Rcpp from CRAN.
looking at the document here, describes the toolchain versions for
lion (xcode 4.2):
http://r.research.att.com/tools/
but it seems likely to me that the newer mavericks (10.9+) builds on
CRAN are built with something newer.
could someone confirm the version of xcode, et al. that i'll need to
achieve c++ binary compatibility with the macOS binaries on CRAN?
with thanks
jonathon
