[Rcpp-devel] Rcpp+bigmemory+inline

The error says that it can't find the boost header file
'boost/interprocess/mapped_region.hpp'. Previously, when the article
was written, this part of boost was packaged as part of bigmemory.
Now, bigmemory links to BH
(http://cran.r-project.org/web/packages/BH/index.html), a CRAN package
assembled by Dirk et al, to get the boost libraries it needs.

This means you likely have to do the same -- change the depends
statement in the C++ to

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

and all should be well -- Rcpp will then know where to find the
necessary boost headers. (Alternatively, of course, you can download
boost yourself.) The article should be updated to reflect that as
well, I think.
