how to start the intel debugger with dgb in emacs

how to start the intel debugger with dgb in emacs

[Mirko]

Hello,

I am trying to invoke the intel debugger (idb) within emacs 22.1 (on
windows).  According to the documentation, I am supposed to invoke gdb
with the following command:

C:\Program files\Intel\IDB\10.0\Bin\idb -gdb -fullname myprogram

However, the space in "Program files" causes a problem. (Searching for
program, no such file)

I have tried putting the path into quotes, and also to quote the space
"\ " while switching to forward-slashes for the rest of the path.  But
that did not help.

I also tried making a shortcut to the executable as C:\idb.exe.lnk.
In that case I get an error message Spawning child process: invalid
argument.  I guess I am making some progress, but I really don't know
where to go from here.

So, I am running out of ideas.

Any suggestions?

Thanks,

Mirko

Try using "C:\PROGRA~1\Intel\IDB\10.0\Bin\idb" instead.

Shortcuts only work if the program is invoked via the Shell API, which
is not what Emacs does.

Thank you Eli.  That did work.

Now that it works, Ii have some other questions, but I'll try to
figure them out by myself first.

I recently made a commit to the CVS repository that fixes this I think.  If you
can't get the CVS version of Emacs, please apply the patch below to gud.el and
evaluate the function string->strings.  Then

"C:\Program files\Intel\IDB\10.0\Bin\idb" -gdb -fullname myprogram

should work.

Shouldn't this patch be applied to the Emacs 22.x branch as well?

It's probably a safe change but I don't know who decides what goes on the
branch.  Using filenames with spaces in seems pretty stupid to me but if it's
commonplace on Windows and I worked on those platforms, I'd probably think
otherwise.

Nick,

I applied your patch, but my emacs complained about undefined variable
string->strings.

I am using Emacs 22.1.1

Thanks to Eli's suggestion, I am not in dire straights.  But I will
not mind testing further modifications, if you have time to supply
them.

That's the additional function Nick sent in addition to the patch (see
above).  You need to put it somewhere, e.g. in your .emacs file.

dum, dum, di-dum, dum (sung with an appropriate tune).  I am not an
expert in patch, and something looked fishy.  Now I understand.

Thank you, and with apologies to Nick for misusing his patch.
