Indeed Rcpp is really awesome.
I have some questions :
- Can we have access to your example (test2.cpp) ?
- Which version of clang do you use ?
And finally what is the output of the following code :
library(Rcpp)
library(RcppArmadillo)
cppFunction(code =
'arma::mat armatrans(arma::mat A) {
return arma::trans(A);
}', depends = "RcppArmadillo")
armatrans(matrix(1:6, ncol = 3))
## [,1] [,2]
## [1,] 1 2
## [2,] 3 4
## [3,] 5 6
Now if this code doesn't work you also check if you have a working fortran
compiler (e.g http://r.research.att.com/libs/gfortran-4.8.2-darwin13.tar.bz2),
you will have more info at
http://cran.r-project.org/doc/manuals/R-admin.html#Mavericks
You can finally try to search the
R-sig-mac<https://stat.ethz.ch/mailman/listinfo/r-sig-mac>archives
too, you will probably find some intersting threads.
Hope it helps
