Objet : Re: [Boost-users] [Boost.Test] How to handle std::valarray<>w/BOOST_CHECK or BOOST_CHECK_EQUAL

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…
