<div>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)</div>
<div><br>
</div>
<div>You can either downgrade to Xcode 4.1 or install a gnu compiler. </div>
<div>I would recommend installing a gnu compiler. You can find the installation package and a tutorial here:</div>

Thanks for the responses. We have tried installing from source and<br>
made sure no other versions are installed. Unfortunately without<br>
success. Could there be anything else missing?<br>

Subject: [Rcpp-devel] Problem with undefined symbols when building<br>
<span class="Apple-tab-span" style="white-space:pre"></span>RcppArmadillo<br>
Message-ID: <CB716C74.34EB%comanor@amazon.com><br>

<br>
Hello Dirk,<br>
<br>
I went through the thread at: http://www.digipedia.pl/usenet/thread/14655/781/ as I seem to be running into the same problem, but wasn't able to determine a possible solution.<br>
<br>
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.<br>
<br>
Here are the undefined symbols dealing with "version":<br>
<br>
nm RcppArmadillo.so| grep -i version<br>
000000000001022e t _GLOBAL__I_armadillo_version<br>
U _ZN4arma12arma_version5majorE<br>

Here are the error messages I get when trying to build R's Forecast library:<br>
Error in dyn.load(file, DLLpath = DLLpath, ...) :<br>
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':<br>
/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<br>
Error : package ?RcppArmadillo? could not be loaded<br>
ERROR: lazy loading failed for package ?forecast?<br>
<br>
----<br>
Is there a specific compiler option that's necessary when building RcppArmadillo? Is this a known bug that was fixed in version 0.2.35?<br>
<br>
Thank you for your help with this issue. Much appreciated,<br>
<br>
