‘trunc_exp’ or ‘trunc_log’.

pasted below. I got the same warning on Linux server as well.
Many of us use Rcpp and RcppArmadillo daily but I have not seen this. I
gather that you use OS X -- so I presume this is clang? What version?
Do you set particular compiler flags? I often use --pendantic.
Did you try adding -Wno-deprecated-declarations as suggested?
Did you chase down which header files this is from?
Lastly, did you poke into the Armadillo header? From the top of my head I
seem to recall that there is a define to suppress error mesages too.
