Re: [Quantlib-users] error C2039: 'rate': is not member of 'QuantLib::io

[Jonathan S. <sw...@gm...>]

Hi Donghee,

   1. All of the cpp files including fixedratebond.cpp are compiled and
   then linked together into the QuantLib library, so yes they are essential
   in the way that the library is currently built. But as a user of the
   QuantLib library, you don’t need to use any of the features that you don’t
   need.

   2. In order to use QuantLib::io::rate you will need to include the
   appropriate header file, just like using a function defined in any other
   library. Please trying adding the following line at the top of all files
   where you use QuantLib::io::rate:

   #include <ql/utilities/dataformatters.hpp>
