Note that R is sensitive to the name of the file and to the file
extension in C and C++ mode. The name of the wrapper file must be the
name of the library. Also in C++ mode, the file extension must be .cpp
rather than .cxx for the R compile command to recognize it.
Note that R is sensitive to the names of the files.
The name of the wrapper file must be the
name of the library unless you use the -o option to R when building the library, for example:
</p>
<div class="shell">
<pre>
swig -c++ -r -o example_wrap.cpp example.i
R CMD SHLIB -o example.so example_wrap.cpp example.cpp
</pre>
</div>
<p>
R is also sensitive to the name of the file
extension in C and C++ mode. In C++ mode, the file extension must be .cpp
rather than .cxx for the R compile command to recognize it. If your C++ code is
in a file using something other than a .cpp extension, then it may still work using PKG_LIBS:
</p>
<div class="shell">
<pre>
swig -c++ -r -o example_wrap.cpp example.i
PKG_LIBS="example.cxx" R CMD SHLIB -o example example_wrap.cpp
</pre>
</div>
<p>
The commands produces two files. A dynamic shared object file called
example.so, or example.dll, and an R wrapper file called example.R. To load these
