</span>See "Writing R Extensions"; this is not a Rcpp issue (though Rcpp offers you<br>
the Rcpp::Rcout "device" to send output to in order to have it synced with<br>
the R standard output).<br>

</span>By default we take care of this:<br>
<br>
// Rcpp has its own stream object which cooperates more nicely with R's i/o<br>
// And as of Armadillo 2.4.3, we can use this stream object as well<br>
#if !defined(ARMA_DEFAULT_OSTREAM)<br>
#define ARMA_DEFAULT_OSTREAM Rcpp::Rcout<br>
#endif<br>
<br>
Maybe you accidentally undefined this...<br>

<br>
</span>The message is rather explicit, something in the object code dboot_multi.o<br>
refers to std::cout. You need to clean that up.<br>
<br>
(I think some folks have some clever macros in their headers to automate<br>
this. I have in the past resorted to explicitly alterting code, or to macro<br>
use to switch to our Rcout as above.)<br>
