Re: [boost] Coroutine2 examples - Cannot link properly.

      thx, Carlos for verifying this issue

It seems I was right.
Boost libs for Arch Linux are not compiled using the standard C++14.
Because of this, Boost.Context cannot support Boost.Coroutine2.
I recompiled Boost-libs with C++14, then reinstalled and now the Fibonacci
example compiles and links correctly with the system libs.
I hope this helps other developers with similar problems.

Ok I was mistaken. It seems that the gnu++14 standard is only used by
default for GCC 6 release, which means that Boost.Context for Arch Linux
was probably not compiled using the C++14 standard.
The macro BOOST_NO_CXX14_INITIALIZED_LAMBDA_CAPTURES is defined if a
standard bellow c++14 is used and consequently,
BOOST_CONTEXT_NO_EXECUTION_CONTEXT macro is defined.
This is probably the reason why GCC is unable to successfully link the
Fibonacci example with the Boost.context system lib.
I will try to compile Boost for Arch linux, forcing the C++14 standard
and
then report here my results.

As I though, none of the macros are defined.
I don't really understand what is going on. I thought the Boost-libs
package from Arch Linux might have been compiled without C++14 support,
but
GCC 5.3 uses -std=c++14 by default, if no standard is provided by the
client.

None of them seem to be defined. I have checked one by one using the
header
files included in the fibonacci example and none of those macros seem
to be
defined.
Is there a test or a "boost" way for me to confirm and to be sure that
none
of those macros are defined?
Just a C++ way <g>. Add to an included header file:
#include 
#if defined(BOOST_NO_CXX11_AUTO_DECLARATIONS) || \
    defined(BOOST_NO_CXX11_CONSTEXPR) || \
    defined(BOOST_NO_CXX11_DEFAULTED_FUNCTIONS) || \
    defined(BOOST_NO_CXX11_FINAL) || \
    defined(BOOST_NO_CXX11_HDR_TUPLE) || \
    defined(BOOST_NO_CXX11_NOEXCEPT) || \
    defined(BOOST_NO_CXX11_NULLPTR) || \
    defined(BOOST_NO_CXX11_RVALUE_REFERENCES) || \
    defined(BOOST_NO_CXX11_TEMPLATE_ALIASES) || \
    defined(BOOST_NO_CXX11_UNIFIED_INITIALISATION_SYNTAX) || \
    defined(BOOST_NO_CXX11_VARIADIC_TEMPLATES) || \
    defined(BOOST_NO_HDR_ATOMIC) || \
    defined(BOOST_NO_HDR_TUPLE)
