Hi Leon (cross-posted to forum)
The "hint" suggests that you run the idl compiler like this:
idl --c++-impl currency.idl
This will generate the same currency.h and currency.cc files as before as well as currency_impl.h and currency_impl.cc. These files should be syntactically and structurally correct but require you to edit them to provide the missing functionality.
You cannot compile any of these files by simply typing
c++ currency_impl.cc
The compiler needs to be provided with additional parameters indicating where to search for header files (eg. CORBA.h) etc. The simplest way of providing these parameters is to make use of a Makefile. Please refer to your tut102 for details.
Regards
Bob
