Re: Getting a symbol table from Gnat 3.15p on Windows

["Marin David Condic" <mcondic.auntie.spam@acm.org>]

That depends on what you mean by the "Debugger". I've got embedded code that
contains within it a "monitor" that will plug to addresses and read from
addresses. It gets requests/data from a communications mechanism and sends
replies/data down the same wire. This is relatively easy to do in an
embedded project. What I'd like to do is build something at the other end
that knows the addresses of the linked image and can send requests to plug
certain ones and get back the contents of certain other ones. I already have
something that does this with the embedded system. So if I basically took
the same code and did what I needed to it to get it to run on a PC, I'd just
need the symbol table so I could be sending the correct addresses. I don't
think I need the debugger - I just need the addresses and the ability to
build an image where nothing is going to stop me from reading/writing to
those addresses.

The whole project is considerably more complicated than this, but it is
predicated on being able to make this (or some similar) "Monitor" inside the
code work on a PC/Workstation and be able to get the symbol table for the
linked image so you know what to tell the monitor to plug & chug. I don't
want to involve a debugger if I don't have to and I don't see how having one
would help me here.
