Surely this is when you try to link your shared objects...

Are you sure you didn't just forget to define the member function

  TASRNlSmlResult::str() const

as denoted in the error message?  The message gives the impression
that it's supposed to be part of your code.  If not,

extension TASRNlSmlResult
: # sources
  whatever.cpp
  
  # requirements and dependencies for Boost.Python extensions
  <template>@boost/libs/python/build/extension

  : # additional requirements
    <library-file>path/to/library/containing/that/function.lib
  ;

HTH,
