Yesterday’s release of RcppBDT 0.2.3
lead to an odd build error. If one used at the same time a 32-bit OS, a
compiler as recent as g++ 4.7 and the Boost 1.54.0 headers (directly or via
the BH package) then the file Want to share your content on R-bloggers? click here if you have a blog, or here if you don't.
lexical_cast.hpp barked and failed to
compile for lack of an 128-bit integer (which is not a surprise on a 32-bit OS).
After looking at this for a bit, and looking at some related bug report, I
came up with a simple fix (which I mentioned in an update to the
RcppBDT 0.2.3 release post).
Sleeping over it, and comparing to the Boost 1.55 file, showed that the hunch
was right, and I have since made a new release 1.54.0-2 of the
BH package which
contains the fix.
Courtesy of CRANberries, there is also a diffstat report for the most recent release. Comments and suggestions are welcome via the mailing list or issue tracker at the GitHub repo.Changes in version 1.54.0-2 (2014-04-14)
Bug fix to
lexical_cast.hppwhich now uses the test for INT128 which the rest of Boost uses, consistent with Boost 1.55 too.
