What architecture are you building for? These intrinsic headers come from boost/integer/common_factor_rt.hpp and: #if ((defined(BOOST_MSVC) && (BOOST_MSVC >= 1600)) || (defined(__clang__) && defined(__c2__)) || (defined(BOOST_INTEL) && defined(_MSC_VER))) && (defined(_M_IX86) || defined(_M_X64)) #include <intrin.h> #endif I'm wondering if the check for x86 needs to be applied to the BOOST_MSVC check as well as the intel one? John.
I'm guessing this might be solvable by updating to a newer version of boost (currently I'm running ver 1.71.0) but before updating, I wondered if there might be something obvious that 'm missing....
I'm building with Visual Studio 2019 and I get a whole bunch of errors simply by adding this line to an empty source file:-
#include "boost/rational.hpp"
It seems to be the same 6 errors but at various different lines - i.e. these errors, over & over again:-
Visual Studio\2019\Community\VC\Tools\MSVC\14.29.30133\include\ammintrin.h(146,19): error C4430: missing type specifier - int assumed.

I just wondered if this might ring a bell with someone? e.g. might there be some preprocesser #define that I should've defined? (or a #define that I shouldn't be defining...)
Thanks for any suggestions, John _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org https://lists.boost.org/mailman/listinfo.cgi/boost-users
