Please try to use the boost.context code from branch develop (github) - I think it is related to see #41 (boost.context) 2017-02-24 7:19 GMT+01:00 Gavin Lambert via Boost-users < boost-users@lists.boost.org>:

At the moment I've no Windows system to test it, but the error might be caused by a missing export statement.
In execution_context_v1.hpp change the code to:
struct BOOST_CONTEXT_DECL activation_record ... struct BOOST_CONTEXT_DECL activation_record_initializer ...
Boost 1.60 doesn't have that file. But making those changes in execution_context.ipp causes the errors mentioned in https://svn.boost.org/trac/boost/ticket/11365 ie. being incompatible with thread_local (thread locals need to be behind a pimpl wall; they can't be exported directly).
I'm about to try updating to 1.63 anyway, so we'll see how that goes, I guess.
Good news: looks like this isn't an issue any more with Boost 1.63. My apologies for the noise.
Although now I have a related-but-different problem.
typedef boost::coroutines2::coroutine<void>::push_type coroutine;
std::vector<coroutine> coros; coros.emplace_back(std::bind(std::forward<F>(f), i, std::placeholders::_1)); // where f is a template functor&& and i is a template iterator
This code compiles fine in: - VS2013 (Windows, Boost 1.55, coroutines1) - VS2015 (Windows, Boost 1.55, coroutines1) - GCC 4.8.2 (Linux, Boost 1.55, coroutines1) - VS2015 (Windows, Boost 1.63, coroutines1 & coroutines2) - GCC 4.8.2 (Linux, Boost 1.63, coroutines1)
But using GCC with Boost 1.63 and coroutines2 I get some quite verbose errors that I'm having trouble making sense of. (Clang 3.4 gives a similar error.) Is this a bug or am I doing something weird?
