The #include goes fine but I still get the following error : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int With the code : BOOST_STATIC_ASSERT(( boost::has_operator_left_shift< int, int>::value )); New version here: http://www.boostpro.com/vault/index.php?action=downloadfile&filename=type_traits-dos.tar.bz2&directory=Extension&
Yes this fixes the error. Now : BOOST_STATIC_ASSERT(( boost::has_operator_left_shift< std::ostream, int >::value )); Yields : boost/type_traits/detail/has_binary_operator.hpp(103) : warning C4913: user defined binary operator ',' exists but no overload could convert all operands, default built-in binary operator ',' used boost/type_traits/detail/has_binary_operator.hpp(139) : see reference to class template instantiation 'boost::detail::has_operator_left_shift_impl::has_operator_left_shift_impl<LHS,RHS,RET>' being compiled with [ LHS=std::ostream, RHS=int, RET=void ] (.....) : see reference to class template instantiation 'boost::has_operator_left_shift<LHS,RHS>' being compiled with [ LHS=std::ostream, RHS=int ] But no more errors, and it seems to work fine despite the warning. Thanks ! MAT.
