bug#1489: gud.el not working with idb

Hello,
I just recompiled emacs (latest version from CVS) but I noticed that gud.el
is not working anymore when used in combination with the intel idb debugger.
After "M-x gdb" I provide the debugger command "idb -gdb -fullname myexe"
(as reported on the idb manual) and the main gud window is loaded. At this
point, whatever I do gud just hangs. For example if I type "r" to run the
executable, gud gets stuck like this:

Current directory is ~/
Intel(R) Debugger for applications running on IA-32, Version 10.1-32 , Build
20070828
------------------
object file name: ciao
Reading symbols from /home/abuttari/ciao...done.
(idb) r



This used to work perfectly until some time ago.

Not being an expert lisp programmer, I just tried to go back in the gud.el
history until I found a revision that works. So in the main branch the
problem is between revision 1.136 (working) and 1.137 (not working).
Revision 1.137 was committed by developer "miles".
Could you please fix this?

Thanks a lot

Alfredo Buttari

I don't have idb available, so I can only try to guess what went wrong.
First of all, does anything change if you change the variable
gud-gdb-command-name from "gdb --fullname" to "gdb --annotate=3"?

This isn't really an Emacs bug as gud.el wasn't designed for idb, but
`M-x gud-gdb' gives the old functionality that you probably want.

Dear Chong,
thanks for taking the time to rspond my question. No, unfortunately it
doesn't change anything and I would be surprised if it did (please correct
me if I'm wrong) since I don't use the default gdb command but

idb -gdb -fullname

Thanks again

Alfredo

Dear Nick,
M-x gud-gdb does not work at all. This is the error I get:

call-interactively: Autoloading failed to define function gud-gdb

Yes I agree this shouldn't be considered a bug. However I imagine it should
be relatively easy to fix since idb provides a gdb compatibility mode (see
the -gdb flag in the debugger command) and would make many users happy. I
may try to learn some lisp and look into this problem myself although
revision 1.136 has everything I need.
Thanks a lot

Alfredo

This error looks very suspect.
Could it be that you have an old gud.el lying around in your load-path?

yes yes my fault. I've tried so many versions that some ended up in my
load-path and was not properly removed.
Thanks a lot
