Hi James and Dirk, James, I want to take the opportunity to thank you again for your competent advice. It worked.
Dirk, does it seem like a reasonable suggestion to you to put the first of these links in your Rcpp FAQ file? This may go a long way to prevent some initial frustration with working with Rcpp for a OS X Maverick user. Thanks again.

I am trying to implement some simple example of a C++ compiled function from Hadley Wickham's website (http://adv-r.had.co.nz/Rcpp.html#rcpp). In fact the function I am trying to compile is the first one: library(Rcpp) cppFunction('int add(int x, int y, int z) { int sum = x + y + z; return sum;}') 2. Unfortunately I have immediately run into a problem, getting an error message: Error in dyn.load("/var/folders/12/bqytpkx93w97r3s3_h9q9k_00000gn/T//RtmprqDXCj/sourcecpp_23c71c355072/sourceCpp_1.so") : unable to load shared object '/var/folders/12/bqytpkx93w97r3s3_h9q9k_00000gn/T//RtmprqDXCj/sourcecpp_23c71c355072/sourceCpp_1.so': dlopen(/var/folders/12/bqytpkx93w97r3s3_h9q9k_00000gn/T//RtmprqDXCj/sourcecpp_23c71c355072/sourceCpp_1.so, 6): Symbol not found: ___addtf3 Referenced from: /usr/local/lib/libquadmath.0.dylib Expected in: /usr/local/lib/libgcc_s.1.dylib in /usr/local/lib/libquadmath.0.dylib 3. I am working on OS X Maverics (10.9.3) and I am using R3.2.0 platform x86_64-apple-darwin13.4.0 arch x86_64 os darwin13.4.0 system x86_64, darwin13.4.0 status major 3 minor 2.0 year 2015 month 04 day 16 svn rev 68180 language R version.string R version 3.2.0 (2015-04-16) nickname Full of Ingredients 4. I'm also using RcppArmadillo_0.6.500.4.0 and Rcpp_0.12.3 5. I can't seem to find any suggestions on the Internet concerning such a problem (maybe somebody will direct me in this regard). 6. I'll be extremely thankful to everybody who can direct me as to how to proceed from here. Of course, I'll be glad to provide any other information should you decide to answer my e-mail and request it. Thank you in advance. Anguel
