Yes, as 

  fatal error: boost/interprocess/mapped_region.hpp: No such file or directory

is pretty explicit. You don't seem to have a full set of boost headers.  When
I do 'locate mapped_region.hpp' on my system I get a few hits from boost
itself, from our BH package (as well as from the dev, sources of BH). So filtered:

edd at max:~$ locate mapped_region.hpp | grep "/usr"
/usr/include/boost/interprocess/mapped_region.hpp
/usr/local/lib/R/site-library/BH/include/boost/interprocess/mapped_region.hpp
edd at max:~$ 

Do you have Boost and/or the latest version of our BH package?  If you have
the latter, try adding

   // [[Rcpp::depends(BH)]]

to your file example.cpp
