The following snippet does not compile with VS2015 and boost 1.61. What should the correct way to do it? Thanks.

This is not a boost question per se. Besides, the solution is described in the error. Good luck.

// 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()); }
