If you are compiling code yourself (not using R itself), there are a few things to watch out for:
</p>
<ul>
<li>The output shared library name (to the left of the file extension) MUST match the module name, or alternatively, you can also set the -package NAME command line argument. See swig -r -help for more information
<li>If you do not set the output file name appropriately, you might see errors like
<div class="shell">
<pre>
> fact(4)
Error in .Call("R_swig_fact", s_arg1, as.logical(.copy), PACKAGE = "example") :
"R_swig_fact" not available for .Call() for package "example"
</pre>
</div>
<li>Make sure the architecture of the shared library(x64 for instance), matches the architecture of the R program you want to load your shared library into
</ul>
