I want to define a dimension stroke_rate, or flow_rate, for that matter. Not
too out of the ordinary for our application. So I am starting with something
like this for my dimensions.
#include
#include
#include
typedef
boost::units::derived_dimensionboost::units::dimensionless_type,1,boost::units::time_base_dimension,-1::type
stroke_rate_dimension;
typedef
boost::units::derived_dimensionboost::units::length_dimension,3,boost::units::time_dimension,-1::type
flow_rate_dimension;
typedef
boost::units::unitourns::units::stroke_rate_dimension,boost::units::si::system
stroke_rate;
typedef
boost::units::unitourns::units::flow_rate_dimension,boost::units::si::system
flow_rate;
However, I am receiving compiler errors when I try and include the units,
Error 1 error C2039: 'value' : is not a member of
'boost::units::detail::dimension_list_tag'
C:\Source\Simulations\tools\boost-msvc90-pro\boost\mpl\aux_\preprocessed\plain\less.hpp
20 CS.Calculations.Managed
Error 2 error C2065: 'value' : undeclared identifier
C:\Source\Simulations\tools\boost-msvc90-pro\boost\mpl\aux_\preprocessed\plain\less.hpp
21 CS.Calculations.Managed
Error 3 error C2039: 'value' : is not a member of
'boost::units::detail::dimension_list_tag'
C:\Source\Simulations\tools\boost-msvc90-pro\boost\mpl\aux_\preprocessed\plain\less.hpp
21 CS.Calculations.Managed
Error 4 error C2065: 'value' : undeclared identifier
C:\Source\Simulations\tools\boost-msvc90-pro\boost\mpl\aux_\preprocessed\plain\less.hpp
22 CS.Calculations.Managed
And so on along these lines. What am I doing wrong with the units and/or
dimensions?
This is quite similar to energy_density_dimension, for example.
typedef
derived_dimension::type
energy_density_dimension;
However, I am failing to see any appreciable difference.
Any thoughts?
Thanks,
Michael
