Build on windows using rwinlib and BH

[jeroen]

Not saying that this is how you need to do it, but at least this will work on win builder so you can download the binary packages put them on your drat.

[eddelbuettel]

It's a little unusual to remove old attribution so I'll probably put this back in.

[eddelbuettel]

I have to think this through. I am not sure yet if that is good. Maybe using the same Boost that QL was build with is better.

But this helps for win-builder. Maybe I just fold it in and out as needed.

[eddelbuettel]

The fail could be

• mixing Boost 1.55 with BH
• related to the older QL 1.11

or something else.

[eddelbuettel]

Your branch fails for me too here, whereas my master passes. I suspect BH + Boost.

[eddelbuettel]

And then it passes.

So with that can you please make three changes to the PR:

1. Pretty-please add the first seven lines of the current src/Makevars.win
2. Remove BH from LinkingTo
3. Maybe add OS_type: unix back in (I am ambivalent about this)

All this gives me a way to build a binary and may keep RQL still off CRAN.

[jeroen]

Without BH we don't have the required boost headers. Also R will refuse to build anything on Windows that has OS_type: unix.

[eddelbuettel]

With BH you bomb on Travis. Travis has had Boost -dev packages installed for years, else it would not work. So we a) do not need BH and b) it creates problems.

What I am basically suggesting that the PR to master restores the Linux functionality. I will then (at least for now) "manually" mod DESCRIPTION to play on Win-Builder.

Does that make sense?

[eddelbuettel]

And you rock. I was just about to ask you to add the Boost headers to the quantlib library in rwinlib, and I see you are already on it. 🥇

[jeroen]

I doubt this will fix it but we'll see. Boost is 120MB of headers alone 😨

[eddelbuettel]

So on Debian/Ubuntu I do libboost-dev libboost-test-dev which will still be lots, but not all. We could do what BH does and use bcp to create the subset we need.

But this is now mergeable, no longer has a conditional DESCRIPTION -- so let me try and see if this will build on win-builder (without OS_type).

[jeroen]

Yes if we can somehow extract the subset of boost headers that quantlib needs that would relieve some of the weight.

[eddelbuettel]

Glance at this script used by BH. Maybe if we just point at 'test'?

[jeroen]

Is it specified anywhere which boostlibs are used by quantlib?

[eddelbuettel]

'Base' (not sure what the name is) for boost::shared_ptr and all that, the boost test framework and maybe one more.

For the Debian package I add the same two as I add for Travis: libboost-dev, libboost-test-dev

[jeroen]

But libboost-dev has everything so that doesn't help us: https://packages.ubuntu.com/bionic/amd64/libboost1.65-dev/filelist

[eddelbuettel]

It does have a lot, as there are interdependencies. But there are a dozen more libboost$FOO-dev. See:

Description: Boost C++ Libraries development files (ALL) (default version)
 The Boost web site provides free, peer-reviewed, portable C++ source
 libraries. The emphasis is on libraries which work well with the C++
 Standard Library. One goal is to establish "existing practice" and
 provide reference implementations so that the Boost libraries are
 suitable for eventual standardization. Some of the libraries have
 already been proposed for inclusion in the C++ Standards Committee's
 upcoming C++ Standard Library Technical Report.
 .
 This metapackage provides the complete Boost development environment,
 including all separately-packaged libraries.
 .
 This package is a dependency package, which depends on Debian's default
 Boost version (currently 1.62).
