Anguel,

Thanks for taking the time to report back -- appreciated.

Seconded.

Yes -- right after James posted this I asked him off-list to take a look at
what is currentlyn the Rcpp FAQ, which he very kindly agreed to do.  The
version is the package is stale-est, the one on GitHub received a recent
updated -- but all this needs work.  I'll also ping other OS X users like
Kevin or Bob Rudis (who, if memory serves, recently wrote a 'R on OS X'
checklist/howto). 

One idea could be to put something basic in the Rcpp FAQ and maybe link to
the wiki within the Rcpp repo -- which we basically don't use at all right
now -- to have a more dynamic reference too.  Thoughts?

Absolutely.  I am spoiled because things tend to 'just work' on Linux [1] so
we all need to keep an eye on current and helpful OS X documentation.  Ditto
for Windows but Rtools is a bit standard(ized) already.

[1] That is unless Ubuntu fscks up clang++ header use, but then again I
mostly use g++.

| 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") :

|         3. I am working on OS X Maverics (10.9.3) and I am using R3.2.0

| 
| 
| 
| 
| 
|         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.
