Re: [Boost-users] boost float128 and Intel's _Quad with Tux Eigen
Thanks John,
The good news is that Intel on Linux does support GCC's __float128 type, so my suggestion would be to: * Remove the #define BOOST_MP_USE_QUAD * Build with -std=gnu++14 rather than -std=c++14 * Remove the -Qoption,cpp,--extended_float_type option.
Unfortunately that didn't work, I get the new compiler error; /home/alex/boost/boost_1_71_0/boost/multiprecision/detail/number_base.hpp(216): error: static assertion failed with "is_integral<T>::value || is_enum<T>::value || std::numeric_limits<T>::is_specialized" BOOST_STATIC_ASSERT(is_integral<T>::value || is_enum<T>::value || std::numeric_limits<T>::is_specialized); Are you able to help?

It shouldn't be required but try adding -DBOOST_HAS_FLOAT128 to the command line. John.

Thanks John,
It shouldn't be required but try adding -DBOOST_HAS_FLOAT128 to the command line.
Unfortunately it now complains of the redefinition of the macro BOOST_HAS_FLOAT128 as well as the previous compile errors. You mentioned that perhaps support was broken somewhere down the lines, would it work with an earlier version of boost do you think?
