I went back and tried to compile the tutorial - and it failed in the same circumstance with the same message. I tried this with current release branch and version 1.54 . I'm pretty much at loss here. I can't believe that I'm the first person to have this problem.
The following code was extracted from something that compiles and is working with 1.53: #include <boost/units/absolute.hpp> #include <boost/units/cmath.hpp> #include <boost/units/io.hpp> #include <boost/units/make_scaled_unit.hpp> #include <boost/units/systems/si/length.hpp> #include <boost/units/systems/si/prefixes.hpp> #include <boost/units/systems/si/time.hpp> #include <boost/units/systems/si/velocity.hpp> #include <boost/units/quantity.hpp> namespace app { namespace units { using boost::units::quantity; using boost::units::quantity_cast; using boost::units::si::length; using boost::units::si::meter; using boost::units::si::meters; using boost::units::si::time; using boost::units::si::second; using boost::units::si::seconds; using boost::units::si::velocity; using boost::units::si::meter_per_second; using boost::units::si::meters_per_second; typedef quantity<length> Length; typedef quantity<time> Time; typedef quantity<velocity> Velocity; } // ... void set_speed(units::Velocity speed); // ... conveyor.set_speed(0.5 * units::meters_per_second); }
