The new Math statistical distributions and special functions code currently fails with Sun's compiler http://beta.boost.org/development/tests/trunk/developer/output/Sandia-sun-bo... with error messages such as: "../boost/math/concepts/real_concept.hpp", line 333: Error: Could not find a match for boost::math::tools::epsilon<boost::math::tools::T>(). "../boost/math/special_functions/detail/unchecked_factorial.hpp", line 268: Error: Could not find a match for boost::math::unchecked_factorial<boost::math::RT>(unsigned). "../boost/math/special_functions/detail/unchecked_factorial.hpp", line 269: Error: Could not find a match for boost::math::unchecked_factorial<boost::math::RT>(unsigned) needed in boost::math::unchecked_factorial<boost::math::RT>(unsigned). The gcc results on that platform are pretty good, so it seems a shame not to support Sun as well, anyone have ideas? Thanks, John Maddock.
