I hope this is of interest/value.

• Date: Thu, 28 Apr 2005 14:21:28 +0100

Hi all,

I usually just passively read selected posts here, but this is an area 
of interest to me and my organization.

For some time now Los Alamos National Lab (LANL), Lawrence Livermore 
National Lab (LLNL), and Sandia National Lab (SNL) have combined forces 
to support work by OpenWorks in its effort to spread Valgrind and its 
tools to other platforms and support for a wide variety of compilers in 
the Linux environment.  Additionally, we'll be adding support for use on 
MPI-based parallel applications.  Julian and Nick have done great work here.

This type of IDE integration is something that is of great interest to 
us at LANL.  We have launched a project called the Eclipse Parallel 
Tools Platform (see http://www.eclipse.org/ptp/).  Valgrind-based tools 
being integrated into this environment would be of interest to us.  To 
start, doing an Eclipse Rich Client Interface for them would be great. 
This would allow them to be used as standalone tools with GUIs or used 
as plugins to the Eclipse IDE.  We're always looking for folks who are 
interested in collaborating on projects like this with us.  If this 
would be of interest to you, please contact me directly.

Thanks,
Brett

Here's how I imagine the KDevelop plug-in works:  you invoke Valgrind 
somehow, and KDevelop works out what options to pass to Valgrind, then 
runs Valgrind (and the user program under it), then collects the output 
somehow, parses it, and presents it to the programmer in the IDE somehow.

So basically Valgrind doesn't need any changes, and there's no need for a 
Valgrind library or anything like that.  In principle an IDE could do this 
with almost any batch program, it just needs to manage the inputs and the 
outputs.

Hello Robert, Nicholas,

Thank you both for your replies. I'll try and collate the information from
both and ask some further questions.

I didn't mean to imply that any of the Valgrind developers would have time
for this, rather that I would try to drum up some interest in the idea in
the Gnome/GTK+ community, and more specifically in the Anjuta team.

I was just thinking of the sort of integration into Anjuta that you see
between Purify and VC++. What it does is embed itself in the IDE, so you can
invoke it conveniently like you said, but it goes a little further than that
perhaps implies, for example warnings pop up as you debug, and there is a
general report of problems and issues at the end of a debugging run, all of
this integrated into the IDE UI. So its sort of both of the above, only that
the IDE is the GUI, hopefully that makes sense.

I am sure that would be worth investigating.

So, knowing that people have managed a similar effort in integration into an
IDE, and knowing the level of integration I thought would be nice (i.e that
level I described when discussing Purify), how does the following statement
impact on the idea in general?

Thanks again for information already supplied, and thanks in advance for any
further information, it is much appreciated,

Regards,

Gaz
