Under cl(MS)/icl(Intel) compiler hash-def '_DLL' denotes dynamic
linking of the C runtime library. Therefore, signals library should
not use this to determine linkage (I may wish to statically link the
signals library, while dynamically linking c-runtime.)
see file boost/signals/detail/signals_common.hpp where the following
snippet is invalid:
#if defined(_MSC_VER) && defined(_DLL)
# define BOOST_SIGNALS_HAS_DLL_RUNTIME
#endif
#if defined(BOOST_SIGNALS_HAS_DLL_RUNTIME) && !defined
(BOOST_SIGNALS_STATIC_LINK)
# if defined(BOOST_SIGNALS_IN_LIBRARY_SOURCE)
# define BOOST_SIGNALS_DECL __declspec(dllexport)
# define BOOST_SIGNALS_BUILD_DLL
# else
# define BOOST_SIGNALS_DECL __declspec(dllimport)
# endif
#endif
here BOOST_SIGNALS_DECL is defined as __declspec(dllimport) as a
consequence of linking the c-runtime dynamically under cl/icl
compilers. But that's not what I wanted - I wanted to link
signals.lib statically.
This same bug is in the regex library. In fact, anyone able to fix
this, should search for _DLL in the BOOST headers.
Cheers,
