I've been using pdb under emacs on an Ubuntu box to debug python
programs. I just upgraded from Ubuntu Edgy to Feisty and this combo
has stopped working. Python is at 2.5.1 now, and emacs is at 21.41.1.
It used to be I could just "M-x pdb RET pdb <script-name> RET" and be
presented with a prompt where I could debug my script, as well as an
arrow in another source code buffer indicating where I am in the
source code.
Now however, when I do "M-x pdb RET pdb ~/grabbers/npr-grabber.py -s
WESUN", I get this is in a buffer called *gud*:
Current directory is /home/levander/grabbers/
No prompt or anything follows it, just that one line. It doesn't pop
up an arrow in the other buffer either. None of the regular commands
like 'n', 's', or 'l' do anything here. So, I did a 'Ctrl-C' and got:
> /home/levander/grabbers/npr-grabber.py(24)<module>()
-> """

It's wierd because at the bottom of that call stack, it does look like
it's wating for input, but no input works... And, after I hit Ctrl-C
I do get a prompt as you see at the bottom of that listing just
above. Now I type "quit" and get:
Post mortem debugger finished. The /home/cponder/grabbers/npr-
grabber.py will be restarted
Anybody can tell me who to get pdb working under emacs on Ubuntu
Feisty?
