Thank you for guidance, Dirk. My package with inclusion of symmatl() builds and loads without issue under Windows using the Rtools toolchain for R-2.13.1. Since my package must build on all platforms supported by R to successfully upload to C-RAN, I will remove symmatl(). This may not be the only Armadillo function not supported under g++4.2.1, however. If anyone is aware of other such functions, please let us know so that we may take it into account in coding packages with RcppArmadillo intended for release on C-RAN. I surely hope the licensing issue resolves and these problems are temporary.<div>

OS X is stuck at a known buggy version of g++, namely g++-4.2.1. Conrad has<br>
some issues with that upstream, we mostly cope.<br>
<br>
I just did a quick grep and symmatl() is defined in a short file<br>
fn_symmat.hpp without any #define or #if statement, and that file is directly<br>
included.<br>
<br>
If the code works on other systems, you may be out of luck. Go complain to<br>
Apple (about not including a g++ version from this decade) or the FSF (for<br>
changing the gcc/g++ license). I don't pick sides here, but I also do not<br>
work on OS X.<br>
