This is sort of piggy-backing on the thread with Michael and Romain. I can't get RccpArmadillo working properly and am looking for suggestions.
I have installed: R 3.0.2 Xcode 5.0.1 and command line tools gfortran libs (i.e., gfortran-4.9-bin.tar) Rcpp package from source (i.e., Rcpp_0.10.6.tgz) RcppArmadillo package from source (i.e., RcppArmadillo_0.3.920.1.tgz) below, "rowSums.cpp" contains a function Romain Francis wrote, and can be seen in the middle of this post: http://www.mail-archive.com/[email protected]/msg05742.html In the R session, I have: > evalCpp("1+1") [1] 2 > sourceCpp("rowSums.cpp") Error in dyn.load("/var/folders/x6/r9tqs57504z47hfz0y3hzplw0000gn/T//RtmppKYsAU/sourcecpp_1b0162749aaa/sourceCpp_8960.so") : unable to load shared object '/var/folders/x6/r9tqs57504z47hfz0y3hzplw0000gn/T//RtmppKYsAU/sourcecpp_1b0162749aaa/sourceCpp_8960.so': dlopen(/var/folders/x6/r9tqs57504z47hfz0y3hzplw0000gn/T//RtmppKYsAU/sourcecpp_1b0162749aaa/sourceCpp_8960.so, 6): Symbol not found: __ZNK4Rcpp7RObject4attrERKNSt3__112basic_stringIcNS1_11char_traitsIcEENS1_9allocatorIcEEEE Referenced from: /var/folders/x6/r9tqs57504z47hfz0y3hzplw0000gn/T//RtmppKYsAU/sourcecpp_1b0162749aaa/sourceCpp_8960.so Expected in: flat namespace in /var/folders/x6/r9tqs57504z47hfz0y3hzplw0000gn/T//RtmppKYsAU/sourcecpp_1b0162749aaa/sourceCpp_8960.so > sessionInfo() R version 3.0.2 (2013-09-25) Platform: x86_64-apple-darwin10.8.0 (64-bit) locale: [1] en_US.UTF-8/en_US.UTF-8/en_US.UTF-8/C/en_US.UTF-8/en_US.UTF-8 attached base packages: [1] stats graphics grDevices utils datasets methods base other attached packages: [1] RcppArmadillo_0.3.920.1 Rcpp_0.10.6 loaded via a namespace (and not attached): [1] tools_3.0.2 Any suggestions?
