[Hana] "basic_tuple.hpp" bug when building with VS2017

Visual Studio 2017 is known to be unable to compile Hana (and other libraries such as Range-v3).
I will be working with the Microsoft folks to make it work as they explicitly reached out to me
with that intent.

Cheers,
Louis

"Visual Studio 2017" refers to four different compilers now, and the latest
of these can compile many things the earliest could not, so if you haven't
checked how 2017 fares in a while, a second look may be worth it.

Re: [Hana] "basic_tuple.hpp" bug when building with VS2017

I should clarify that I am using VC++ v141 toolset. I just installed VS2017 last week so I think this is the latest release.

Adding /permissive- or not does not fix the issue.
I tried all the following flags as well: /std:c++14, /std:c++17 and /std:c++latest.

FYI, I submitted the issue on Microsoft's end as well. Link here: https://developercommunity.visualstudio.com/content/problem/255672/boosthana-bug-when-building-with-vs2017.html

I am almost certain it is a MSVC++ compiler issue since I switched to the Clang compiler and it successfully built.

Could you please give a minimal source file that triggers the error?

...failed updating 510 targets...
...skipped 1528 targets...
...updated 6019 targets...

Many of the failures are because

C:\boost-git\develop\libs\hana\test\_include\laws/base.hpp(105): error
C2580:
'boost::hana::test::trap_construct::trap_construct(boost::hana::test::trap_construct
&)': multiple versions of a defaulted special member functions are not
allowed

With that fixed, the result is

...failed updating 151 targets...
...skipped 451 targets...
...updated 1810 targets...

So it's not like everything works (the compiler crashes quite a few times),
but on the other hand, things look far from totally unusable.

Compiles for me. Visual Studio 2017 15.7.2. _MSC_VER=1914.

I can't reproduce your error, sorry. There's something different between our
configurations and I don't know what that is.

Boost - Dev mailing list
I'm actively working with the MSVC folks at fixing their issues here:

  https://github.com/boostorg/hana/issues?q=label%3AMSVC+

If you see additional problems that are not being addressed up there,
please submit an issue on GitHub -- this is the preferred way to track
issues with Hana.
