Addition of (all of) boost/polygon (to also include voronoi.hpp)

[Jean-Romain]

I'm currently using boost/polygon/voronoi.hpp to make a fast Delaunay triangulation of large point cloud. Everything was good and I was very happy until I tested the package on CRAN. It does not compile because fatal error: boost/polygon/voronoi.hpp: No such file or directory

I was perplex until I found that on my machine (linux) all the boost header are installed but some are missing in BH. This is why it compiles on my machine but not on CRAN.

I understand that some boost stuff are not in BH but it seems to me that the voronoi stuff is header only. Actually only 3 voronoi_*.hpp headers are missing but most of them are actually present in BH.

So I'm wondering why they are missing? if they can be added in BH? and if it is a viable option to include these files in my own package as a workaround.

BH adds by Boost library, so your issue really may be whether polygon can be added. (Boost headers tends to inter-depend quite a bit so it is never "just three files".)

That said, Boost polygen appears to be a standard header-only library. We appear to have some files from it already (that happens prevcisely via the aforementioned interdepencies resolved by the bcp tool also used to build BH). So by adding all of polygon you should be set.

I will retitle the Subject: and put it on TODO list.

Thank you Dirk. I now understand why polygon is only partially included in BH. polygon is not actually included in BH at all it is only a side effect of interdependencies in other included parts of boost.

As a workaround I temporarily included polygon in my own package. At least it compiles on CRAN and on rhub. I'm wainting for an update of BH. Anyway I won't release before 2020.

Best.

Yes, locally adding polygon (preferably from the same Boost release as BH) is the best next step in the very short term. I will try to add polygon to BH at the next update, but I make those fairly infrequently. So if you're not in a rush either we're all good for now. But this should get addressed in due course.

Preparing BH 1.72.0 now based on last week's Boost 1.72 release -- with polygon.
