Hi,
Did you build it using boost bootstrapping or you have to do some “hacks”?
Does your experience apply to 1.61 RC or 1.60 too?

I've successfully compiled Boost 1.61.0 Beta 1 Release Candidate with VC14 (no Clang-Cl.exe) in debug and release.
This has exposed the "hacks" I mentioned earlier in this thread. When compiling my test program with Clang-Cl (latest) and VC14, the following errors are reported. (in my hacks I just added std:: to the boost code in the appropriate places, untill Clang stopped complaining.

Then there are more errors, but they are either the same as the ones I've reported earlier, or the result of the above errors.
Have a good day,
