[Boost-users] [test] BOOST_CHECK_EQUAL type to stream

I understand why the types of the arguments to BOOST_CHECK_EQUAL (and
BOOST_CHECK_PREDICATE, etc.) must have operator<< correctly defined.
Otherwise, the failure message could not be properly printed.

The type I want to check is vector<int>. But it seems not to be enough to
simply define the following function:

ostream& operator<<(ostream& out, const vector<int>& vec);

The error message is long and very templatey, but the essence is:

.../test_tools.hpp:298: error: no match for 'operator<<' in 'ostr << t'

What more should I do to be able to use vector<int> in these tests?

Thanks!
