[Rcpp-devel] Rcpp problem related to sourceCpp_1.so

[aakremena at aol.com]

Hi everyone,

My name is Anguel and I am new to this list.

    1. 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") :

                         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
