[R-SIG-Mac] installing Rcpp on R compiled with intel composer on OSX Yosemite

[Rohit Narula]

Inspite of succeeding with the compilation of R-3.1.2 using the intel suite of compilers ver.2015.0.077 including MKL on my late 2014 MacBook Pro running Yosemite (outlined here <http://feng.li/r-with-icc-mkl/>), I am unable to install the excellent Rcpp package that I have been thoroughly enjoying thus far via the prepackaged binary R for Mavericks. Now, I would like to speed things up a bit, in particular use OpenMP that is seemingly incompatible with the default clang. I am aware of the OpenMP/clang project but it seems that installation on Yosemite is still dodgy.

Apart from several mentions of Warning in strptime during make -j8, make installcompletes successfully and I am able to install most packages on the freshly compiled R. The Rcpp package nevertheless fails with:

> install.packages("Rcpp")

compilation aborted for Date.cpp (code 2)
make: *** [Date.o] Error 2
ERROR: compilation failed for package ‘Rcpp’
Is there a way to fix this? Alternatively, how can I switch compilers to be able to invoke 'OpenMP' via Rcpp on my MacBook?
