[R-SIG-Mac] Updating to Mavericks

[peter dalgaard]

Thanks Brian.

One more item: If building from SVN, you may need to run "svn upgrade" in the source directory (at top level).

I suppose that's a consequence of upgrading Xcode rather than Mavericks per se, but might as well mention it here.

Do we have any authoritative advice as to what should go into config.site? Mine seems to work unchanged, but I'm not sure I have a clue about what they are doing anymore.

Otherwise you could select clang as your compiler: see http://cran.r-project.org/doc/manuals/r-release/R-admin.html#OS-X-packages . There are also compilers called 'gcc' and 'g++' in Xcode 5.0.1: these are clang-based but are not quite the same as clang/clang++.  Although g++ reports

The external software at http://r.research.att.com/libs/ which I know does is gdal and zeromq. It would be prudent to compile Rcpp with the same compiler as a Rcpp-using package, although not always necessary.
