<br>

<font size="3">My name is Anguel and I am new to this list.<br>

<br>

    1. I am trying to implement some simple example of a C++ compiled function from Hadley Wickham's website (<a href="http://adv-r.had.co.nz/Rcpp.html#rcpp" target="_blank">http://adv-r.had.co.nz/Rcpp.html#rcpp</a>).<br>

In fact the function I am trying to compile is the first one:</font></font><br>

<pre class="sourceCode r"><code class="sourceCode r"><span class="kw">library</span>(Rcpp)
<span class="co"></span>
<span class="kw">cppFunction</span>(<span class="st">'int add(int x, int y, int z) {</span>
<span class="st">  int sum = x + y + z;</span>
<span class="st">  return sum;</span>
<span class="st">}'</span>)<br>

<br>

</code><font face="Arial, Helvetica, sans-serif" size="3">       2. Unfortunately I have immediately run into a problem, getting an error message:<br>

                         Error in dyn.load("/var/folders/12/bqytpkx93w97r3s3_h9q9k_00000gn/T//RtmprqDXCj/sourcecpp_23c71c355072/sourceCpp_1.so") : <br>

<br>
                                    Rcpp_0.12.3<br>

<br>

        5. I can't seem to find any suggestions on the Internet concerning such a problem (maybe somebody will direct me in this regard).
<br>

        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.<br>

<br>

Thank you in advance.<br>
