c++ - boost::multiprecision::float128 and C++11 -


i'm trying use boost::multiprecision::float128 (boost 1.55.0) under c++11 (gcc 4.8.1), following compiler error:

/cm/shared/apps/boost/gcc/1.55.0/include/boost/multiprecision/float128.hpp: in static member function ‘static std::numeric_limits<boost::multiprecision::number<boost::multiprecision::backends::float128_backend, et> >::number_type std::numeric_limits<boost::multiprecision::number<boost::multiprecision::backends::float128_backend, et> >::min()’: /cm/shared/apps/boost/gcc/1.55.0/include/boost/multiprecision/float128.hpp:533:55: error: unable find numeric literal operator ‘operator"" q’     static number_type (min)() boost_noexcept { return 3.36210314311209350626267781732175260e-4932q; }

can't use boost::multiprecision::float128 in c++11? or how else working?

edit

just clarify. error generated 

#include <boost/multiprecision/float128.hpp>

the compiler not happy statement

return 3.36210314311209350626267781732175260e-4932q;

in particular q confusing it. used compiler flags -std=c++11 -fabi-version=0 -march=native -mfpmath=sse

it looks known issue. try compiling -fext-numeric-literals.
