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. <div>
<br></div><div>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. </div><div><br></div><div>Thank your for help and suggestions. Terrance<br>

<div>Dear Rcpp experts, I'm finding difficulty to build a package (created on Win) that uses Rcpp and RcppArmadillo on the Mac. I've attempted the build on multiple machines to rule out local issues. I find a June 27 post on the Rcpp list (<a href="http://lists.r-forge.r-project.org/pipermail/rcpp-devel/2011-June/002548.html" target="_blank">http://lists.r-forge.r-project.org/pipermail/rcpp-devel/2011-June/002548.html</a>) that experiences very similar "dlopen" issues as I show below, though the cause is attributed to proper construction of C++ templates. In my case, I do not create any templated classes; only use those in Rcpp and RcppArmadillo. In this regard, please note the upstream syntax errors when attempting to include libRcpp.a.</div>
