OK, looking at the results I have an idea where the problem *may* lie for some of the failures, can you try the attached updated test_constants.cpp and see if it passes or not on QNX?
It passes. What's the easiest way to (re-)run a single test?
Oh :-( Single tests can be run by: cd into libs/math/test bjam toolsetname test_name Anyhow, I'm stumped by what the issue could be now, so can you let me have the output of the program below? Many thanks, John. #define BOOST_MATH_INSTRUMENT #include <boost/math/special_functions/ellint_1.hpp> #include <boost/math/concepts/real_concept.hpp> int main() { std::cout << std::setprecision(30); boost::math::concepts::real_concept r = boost::math::ellint_1<boost::math::concepts::real_concept>(0.5, -10); std::cout << r << std::endl; }
