Hi,
In 2012, boost::base_from_member was equipped with variadics machinery to perfect-forward construction arguments to the contained member. Unfortunately, Solaris Studio 12.5 on Intel chokes on it (http://tinyurl.com/no7trgb ):
"../boost/utility/base_from_member.hpp", line 137: Error: Parameter pack 'x' not expanded with '...' [...]
Oddly enough, the same compiler does work fine on Sparc. May I suggest that lines 129-132 of boost/utility/base_from_member.hpp
#if !defined(BOOST_NO_CXX11_RVALUE_REFERENCES) && \ !defined(BOOST_NO_CXX11_VARIADIC_TEMPLATES) && \ !defined(BOOST_NO_CXX11_FUNCTION_TEMPLATE_DEFAULT_ARGS) && \ !(defined(__GNUC__) && (__GNUC__ == 4) && (__GNUC_MINOR__ < 4))
be added a special provision for this environment (the same way it already has for GCC 4 and prior)?
#if !defined(BOOST_NO_CXX11_RVALUE_REFERENCES) && \ !defined(BOOST_NO_CXX11_VARIADIC_TEMPLATES) && \ !defined(BOOST_NO_CXX11_FUNCTION_TEMPLATE_DEFAULT_ARGS) && \ !(defined(__GNUC__) && (__GNUC__ == 4) && (__GNUC_MINOR__ < 4)) && \ !(defined(__SUNPRO_CC) && defined(__i386) && (__SUNPRO_CC <= 0x5140))
I can't unfortunately test this myself as I don't have access to the compiler. FWIW, my interest in having this fixed is that it's seemingly the only bug preventing Oracle Solaris Studio 12.5 on Intel from supporting Boost.MultiIndex. Thank you for reporting this. I will follow up on this.
