Dear List,
Just a super naive (dumb) question: after upgrading to
RcppArmadillo_0.6.700.3.0 Rcpp_0.12.4, I receive compilation warning ''log_max'
has been explicitly marked deprecated here” on every line of my code that uses
‘trunc_exp’ or ‘trunc_log’.
I wonder how to fix this. The code to reproduce the warning and the log are
pasted below. I got the same warning on Linux server as well.
Thanks a lot in advance,
Yue
Code:
#include <RcppArmadillo.h>
// [[Rcpp::depends("RcppArmadillo")]]
// [[Rcpp::export]]
double trunc_exp_Rcpp(double x) {
return arma::trunc_exp(x);
}
Outputs log:
> Rcpp::sourceCpp('tmp.cpp')
