operator==( std::valarray<double> const&, std::valarray<double> const& )
 
returns 
 
std::valarray<bool>
 
which is not bool convertible value
 
You will either have to use by element comparison or write your own predicate that compare the valarrays
 
BOOS_CHECK_PREDICATE( my_valarray_comp, (v1)(v2) );

        Hello,
         
        I am using the Boost.Test framework, but I not able to use std::valarray<> with BOOST_CHECK or BOOST_CHECK_EQUAL macro.  
         
        For example:
        <\code>
        static void print_valarray(std::ostream& os, std::valarray<double> const& v)
        {
          // TODO
        }
         
        namespace std {
        std::ostream&
        operator<< (std::ostream& os, std::valarray<double> const& v)
        {
          print_valarray(os, v) ;
          return os ;
        }
        } ;
         
        std::valarray<double> v(10) ;
        BOOST_CHECK_EQUAL(v, v); 
        <\code>
         
        Failed with the following compilation error:
        c:\Dev\MViala\ADV\Library\boost-1_33_1\boost\test\predicate_result.hpp(51): error C2664: 'boost::test_tools::predicate_result::readonly_property57::readonly_property57(const boost::test_tools::predicate_result::readonly_property57::write_param_t)' : impossible de convertir le paramètre 1 de 'std::_Boolarray' en 'const boost::test_tools::predicate_result::readonly_property57::write_param_t'
         
        Configuration:
        Platform: Win32
        Compiler: Microsoft Visual C++ version 7.1
        STL     : Dinkumware standard library version 313
        Boost   : 1.33.1
         
        Any help will be appreciated...
