Our BH package provides a sizeable portion of the Boost C++ libraries as a set of template headers for use by R. It is quite popular, and frequently used together with Rcpp. The BH CRAN page shows e.g. that it is used by rstan, dplyr as well as a few other packages. The current count of reverse dependencies is at 159.
Boost releases every four months. The last release we packaged was 1.66 from February---and a new Boost 1.69 just came out. So I packaged it, being somewhat careful as usual as CRAN insists on suppressing compiler diagnostics #pragma statements and a few other things, see the BH GitHub repo for details.
Given the rather ginormous footprint of BH -- in this release about 154mb installed -- I am proceeding carefully as usual. I started with two full reverse-depends checks on the weekend which lead to three regressions for which I will contact the two corresponding maintainers (as it affects me for the third package). Details follow. In short, we should be in good shape to release in due course. Details are below on how to access the package now for testing and local use.
Upgrading BH on CRAN from 1.66 to 1.69
We ran two initial reverse-dependency checks, with results pushed to the usual repo. The finally summary is in this file with the moneyline being
141 successes, 10 failures, and 8 skipped packages.
Of the 10 failures, four are due to missing depends or suggests: these packages passed once installed. Of the remaining six, three are recurring issues we also have with e.g. Rcpp. That leaves three new regressions, or as CRAN calls it, 'change to worse'. We also verified that these packages do indeed pass with the CRAN version of BH, i.e, 1.66.
What follows is a short discussion of each respective package.
First regression: phonics
The package uses
which flattens namespaces---and with Boost 1.69 now gets a collision as distance() is no longer unique. Simply prefixing the four or five occurrances with std:: fixes it. The complete (and very short) patch follows.

Second regression: RcppStreams
Here we end up with a linking error. The following symbol, expanded with c++filt is coming up as missing:
I am the upstream author/maintainer here. This looks somewhat tricky, but a quick commenting-out of an optional / verbose display call does the trick. So that is what we may end up doing.
Third regression: TDA
This generated a lot of messages with error: ‘next’ is not a member of ‘boost’ when boost::next(somevar) was invoked. A quick Google search suggests that the declaration moved to another header file and that including boost/next_prior.hpp should fix it -- and it does. One-line patch follows.
That may not be the best place for the include but it demonstrated that we simply need to add it somewhere so that diag.cpp compiles.
Package Access
We installed the release candiate package in the ghrr drat repo. To install BH 1.69.0-0, either install the drat package and set the repo as described at the ghrr drat repo, or just do
This will allow for continued testing of BH 1.69.0 before we upload it to CRAN, probably early January.
Comments and suggestions about BH are welcome via the mailing list or the issue tracker at the GitHub repo.
