Hi I was wondering how to include files into your
project without actually adding them to your project view
in Borland 5.02?
What I do is I  go to options->project->directories and set
the path to the required header files (cpp files in same path
as the header files). Then I include the header for the object I need
within the header file that I need the definition.

example inside of TimerAgent.h

#include "TransientAgent.h" //which is in a different dir

then I declare a class
class TimerAgent: public TransientAgent

constructor deffinition
TimerAgent::TimerAgent(int port,string name):TransientAgent(port,name){}

now it compiles fine until the linking then I get many
unresolved external errors example:

Error: Unresolved external 'TransientAgent::TransientAgent(int,string)'
 referenced from ...

I know it finds the header file for TransientAgent because TransientAgent
inherits from AbstractProcess which is not directly used in this project and
some of the unresolved externals refer to AbstractProcess. Now the file
structure
 is huge for all the nesting involved in the creation of Transient Agent and
I have
 no wish to have 40 extra files cluttering my workspace. The TransientAgent
code has been tested and works fine as a stand alone project so what I want
to
know is how does one use files in another dir without adding them explicitly
to
your project?If that is what my problem is...

Thanks for any help in advance
Trevor
