DDE Debugger

Ian Cattrell — Wed, 25 Oct 2000 08:25:16 GMT

Is it still possible to download the DDE debugger from the HP website? From what I've seen WDB seems to be the replacement for DDE, but I have not been able to use it to obtain real time call stack/register info from a running process (Due to WDB stopping the process when you attach to it). Is there a way to view stack info in real time with WDB or is DDE still available for download?

Thanks

Sorry no nothing about the real time question but maybe the following will help nevertheless ?

Q. What is HP's direction with debugger support?
My customer is currently a DDE user and would like to continue using it, but they have some concern about us moving to WDB only. Is our
direction to continue supporting both?

A. Currently, HP supports both DDE and WDB on 11.0, but WDB is becoming the standard HP debugger for high-level languages. New features
are being added to WDB to support compiler features such as +objdebug. The last few DDE releases have been maintenance releases and included
only defect fixes. DDE will not be available on new architectures such as IA-64.

HP has not decided when/if to obsolete DDE. However, we are encouraging customers to move to WDB as the debugger of choice. Plans are
underway to add more functionality to WDB (such as more Fortran support) to make the transition easier. Customers can obtain the latest version of WDB from the HP Web at: http://www.hp.com/go/wdb/.

The DDE lab has built a new version of DDE for 11.x.
Version 4.23 is available on the June 2000 HP-UX Application CDs

Hi Ian,

It is not possible to download the DDE debugger from the HP website; it is available only via applications CDs through any of the compiler installs.

What do you mean by WDB stopping the process? Do you mean it kills the process, or that it temporarily stops execution when you attach letting you resume with a continue afterwards? If its the latter this is the intended behaviour of the debuggers, both DDE and WDB. It is impossible for either debugger to obtain a stack trace without stopping the process first.

If you are having problems with WDB make sure you have the latest version from the website.
