See "Writing R Extensions"; this is not a Rcpp issue (though Rcpp offers you the Rcpp::Rcout "device" to send output to in order to have it synced with the R standard output). | This post referenced a similar issue: http://comments.gmane.org/ | gmane.comp.lang.r.rcpp/3071 | | A Google search seems to indicate many packages have similar notes:https:// | www.google.com/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=Found+ | '_ZSt4cout'+note+package | | For example, bayes-tree: http://www2.uaem.mx/r-mirror/bin/windows/contrib/3.1/ | check/BayesTree-check.log | | This is the only note remaining -- everything else went through without issue | and '_ZSt4cout' was not part of any code that I had written. I am importing | Rcpp and RcppArmadillo for 2 functions used in the package. I am stumped, but By default we take care of this: // Rcpp has its own stream object which cooperates more nicely with R's i/o // And as of Armadillo 2.4.3, we can use this stream object as well #if !defined(ARMA_DEFAULT_OSTREAM) #define ARMA_DEFAULT_OSTREAM Rcpp::Rcout #endif Maybe you accidentally undefined this... | assume that I would not be allowed to push a package to CRAN which has this | note. Any help would be most appreciated! The message is rather explicit, something in the object code dboot_multi.o refers to std::cout. You need to clean that up. (I think some folks have some clever macros in their headers to automate this. I have in the past resorted to explicitly alterting code, or to macro use to switch to our Rcout as above.)
