I guess you are using Xcode 4.2 or later. There the new llvm compiler is used for g++ which is causing problems with Rcpp. This compiler is working for some Rcpp things but mainly fails. I had similar errors and couldn't get the llmv compiler to work with Rcpp. It seems that mainly all vector operations fail (like repp sugar and also your example)
You can either downgrade to Xcode 4.1 or install a gnu compiler. I would recommend installing a gnu compiler. You can find the installation package and a tutorial here: http://woss.name/2012/01/24/how-to-install-a-working-set-of-compilers-on-mac-os-x-10-7-lion/ for me after changing the compiler everything worked. josef ---------------------------------------------------------------------- Message: 1 Date: Mon, 27 Feb 2012 12:01:52 +0100 From: Sacha Epskamp <sacha.epsk...@gmail.com<mailto:sacha.epsk...@gmail.com>> To: rcpp-de...@r-forge.wu-wien.ac.at<mailto:rcpp-de...@r-forge.wu-wien.ac.at> Subject: Re: [Rcpp-devel] Problems on a new Mac Message-ID: <cahldboiym2oc1-rhpqeulupofdbbxr2cjg9v+2ulqvlmmxe...@mail.gmail.com<mailto:cahldboiym2oc1-rhpqeulupofdbbxr2cjg9v+2ulqvlmmxe...@mail.gmail.com>> Content-Type: text/plain; charset=ISO-8859-1 Thanks for the responses.

If I put the code in a package, there is no problem. But what I am getting is: library(Rcpp) dyn.load("add.so") mod=Module("adding") add=new(mod$adding,1.2,3.4) Error in Module(module, mustStart = TRUE) : Failed to initialize module pointer: Error in FUN("_rcpp_module_boot_adding"[[1L]], ...): no such symbol _rcpp_module_boot_adding in package .GlobalEnv The packages that you reference are all, well, packages, and from what I can tell about .onLoad(), that applies only to packages. And the loadRcppModules function, apparently, must be called from an .onLoad function (because I get an error message to that effect). I have never had a problem loading compiled functions this way; it appears to be only an issue with modules. I would appreciate some helpful suggestions from anyone in R-land who may have had some success with this (e.g., specific documentation pages to look at, code snippets that have worked for others, or other useful suggestions on what to try next). Of course, if what I want to do is known to be impossible, that would also be a helpful response.

Here is an example: My personal approach is to follow the path of least resistance on __start from an existing package__ having the feature I want to use. Rcpp comes with modules-using packages as part of the documentation (Rcpp modules vignette) and unit tests. And there is even a package skeleton generator (for which you can set an option to use modules). And among the now 55 CRAN packages using Rcpp (!!), a few use modules too. One is my RcppBDT package, there are the two packages by Baptiste (cda, planar) and probably a few more but one can't tell from the DESCRIPTION. Your code may have been fine, but you also need to look at the .onLoad or .onAttach function etc. So starting from a working stanza really strikes me as easiest.

Basically, I'm trying to build R's RcppArmadillo, and although the build does succeed, it has undefined symbols in the binary library file RcppAramdillo.so which causes R's Forecast library, which depends on RcppArmadillo, not to build as a result of these undefined symbols. I'm trying to build Forecast 3.16 using RcppArmadillo 0.2.34 and Rcpp 0.9.9. Here are the undefined symbols dealing with "version": nm RcppArmadillo.so| grep -i version 000000000001022e t _GLOBAL__I_armadillo_version U _ZN4arma12arma_version5majorE U _ZN4arma12arma_version5minorE U _ZN4arma12arma_version5patchE Here are the error messages I get when trying to build R's Forecast library: Error in dyn.load(file, DLLpath = DLLpath, ...) : unable to load shared object '/rhel5pdi/workplace/comanor-ws/build/RsRcppArmadillo/RsRcppArmadillo-0.2.34/RHEL5_64/DEV.STD.PTHREAD/build/lib64/R/library/RcppArmadillo/libs/RcppArmadillo.so': /rhel5pdi/workplace/comanor-ws/build/RsRcppArmadillo/RsRcppArmadillo-0.2.34/RHEL5_64/DEV.STD.PTHREAD/build/lib64/R/library/RcppArmadillo/libs/RcppArmadillo.so: undefined symbol: _ZN4arma12arma_version5majorE Error : package ?RcppArmadillo? could not be loaded ERROR: lazy loading failed for package ?forecast? ---- Is there a specific compiler option that's necessary when building RcppArmadillo?
