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.


#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;
