execution_context.hpp gives errors when building with VS2015RC

[robvdnieuwenhof@…]

When building boost 1_58 wirh VS2015RC it gives the following errors:

Unknown compiler version - please run the configure tests and report the results

Unknown compiler version - please run the configure tests and report the results

This is the message Boost.Config shows as error when the compiler version is not supported.

I don't know if this is a version to support. Anyway, moving the ticket to Boost.Config

[John Maddock]

Sorry to ping this back to you - but the Config message is exactly that - an informative message to say you're using a version of Boost released before the compiler you're using. In point of fact we do have some VC2015 support in 1.58, but it might not be up to date with the latest VC RC (which does have a few new features I believe).

The first *error* is definitely a Boost.Thread issue.

[John Maddock]

Forgot to say - we don't officially support pre-release compilers.

[viboes]

The errors are from Boost.Context :)

moving the ticket to Boost.Context in case there is something to fix there.

then how to solve the problem?

FYI, this same error message is now happening with VS 2015 RTM. I hope this is being fixed in Boost 1.59.0.

[John Maddock]

It appears to build fine in the master branch, so I believe this should be fixed in the next release (I haven't checked the release candidate though).

seams to be fixed - so closed
