Hello again Rcpp Experts, I would appreciate any insight or guidance you may offer on the errors (noted in red, below) when trying to build a package composed under Windows on the Mac. My package uses Rcpp and RcppArmadillo with no added self-defined template constructions. The Macs on which I've attempted build have the latest versions of R, Rcpp and RcppArmadillo and are able to run C++ code with these classes using inline.
The "dlopen" error message is similar to a previous post and suggests some sort of template definition problem. I do not define any templated classes, however. Thank your for help and suggestions.
