How to invoke idb from emacs

[mirko_vukovic]

Hi,

I am having trouble following the debugger documentation to invoke the idb(V10) debugger from within emacs 22 (on windowsXP+cygwin)

My procedure is to load the source file, and invoke gdb. I am then prompted as follows:

Run gdb (like this):

To which I reply:
C:Program FilesIntelIDB10.0IA32inidb -gdb -fullname mycode.exe

Emacs complains about spawning child process: invalid argument. I think the problem lies in the space in "Program Files". I tried various combinations of backward slashes, quotes, etc, but no success.

Many thanks,

Mirko

Emacs in the cygwin environment will spawn via the cygwin libraries. My recommendations is to try the "unix path" version of the IDB. Type
cygpath --unix "C:Program FilesIntelIDB10.0IA32binidb"
Note the to escape the
Use the translated path instead and see if that works.
The other part of the equation is that idb will expect a Windows style name. Thus, the argument you pass to idb as the file name needs to be something that idb understands.

James,

I was not clear enough in my post (too many installed components on my computer) . I am using the windows version of emacs (downloaded from the gnu web site)

I asked the question on gnu.emacs.help, and got an answer that got me somewhere. I should invoke idb with:

c:progra~1intel...
(that may need to go as a correction for the documentation)

Now the debugger works. The display in emacs is not quite right, but the interaction with the debugger seems to work.

Thanks,

Mirko

As a follow up on this thread, there is a resolution for this issue.

Nick Roberts posted a patch for gud.el on gnu.emacs.help. You can find it on this thread:

how to start the intel debugger with dgb in emacs

It basically consists of calling string->strings instead of string-strings. His post contains the definition of string->strings function.

At the same time, I learned the intel is dropping idb development after this release. So the issue may be moot :-(

Just to clarify - we will no longer be developing idb for Windows. idb for Linux and MacOS will still be there. Windows users seem to universally prefer the MS debugger, though I can understand why you might want to use idb from Cygwin.

It's not going away for a while yet, though.
