The following snippet does not compile with VS2015 and boost 1.61. What should the correct way to do it? Thanks.
// compile with cl.exe /EHSc
#define BOOST_TEST_MODULE pair
#include
std::pair v()
{
return std::make_pair(0, 0);
}
BOOST_AUTO_TEST_CASE(range)
{
BOOST_TEST(std::make_pair(0, 0) == v());
}
Here's the error message:
