I have been successfully using Rcpp for a while, and recently started
trying to use RcppArmadillo. I found it worked fine on linux, but on
Mac OS X 10.7, it fails.
Even the trivial example below fails, with the errors shown at the bottom.
library(inline)
f = cxxfunction(signature(x="numeric"), ";", ,plugin = "RcppArmadillo")
The udnerlying error seems to be that I do not have 'libgfortran'.
This is indeed true, as fortran is not provided in mac os x any more.
I can download and build armadillo examples independantly and they
work fine. They use the command line:
g++ -I /usr/local/include -O1 -o example1 example1.cpp
-larmadillo -framework Accelerate
I'm not sure how R / Rcpp / RcppArmadillo decide how to build, so I'm
not sure where I should be looking to (I assume) change -lgfortran for
-framework Accelerate ?
Full R log follows:
