Boost.Log: Linker error with MSVC14

[marci_r@…]

MSVC14 has a completely refactored CRT: ​http://blogs.msdn.com/b/vcblog/archive/2014/06/10/the-great-crt-refactoring.aspx

Trying to compile Boost.Log with it gives a linker error because there is no function _getptd (referenced in src\unhandled_exception_count.cpp).

The function is now called __vcrt_getptd. It returns a pointer to a new struct __vcrt_ptd. The part before _NLG_dwCode from the old struct _tiddata is missing, apart from that it looks the same.

See VC\crt\src\vcruntime\vcruntime_internal.h in the MSVC14 directory.

Wow, that was fast! Thank you very much!

As of Visual Studio 2015 CTP 6, the __vcrt_getptd symbol isn't exported, but Microsoft have introduced __processing_throw as a direct accessor for the required value, which we can hope will be maintained going forward.

For whatever reason the latest MSVC CTP does not install half of the headers on my system and as a result is completely unusable. This looks worse than an alpha release to me. I'll probably not support CTPs and wait until the final release is out. If it's still not working then, I'll deal with it as the compiler gets officially supported by Boost.

I tried to install MSVC on a clean system and it worked. Here is the fix: ​https://github.com/boostorg/log/commit/4751a165366dd9d1cf55252c290eaacf39a59552.
