Re: [Boost-users] does boost::variant support 128 bit integer?

If you just have:

#include #include <string>

boost::variant<__int128, char, std::string> v; v = 56;

This produces an error:

..\..\../boost/variant/variant.hpp:1578:38: error: call of overloaded 'initialize(void*, boost::move_detail::remove_reference::type)' is ambiguous

That's because it /is/ ambiguous. The compiler does not know if you want to set the variant to a '__int128' or to a 'char'. You get the same error message if you substitute 'long' for '__int128'. -- Rainer Deyke (rainerd@eldwood.com)
