I tried to debug a source file named "test.py", which contained only
one
line: "i = 1". In windows command-line, I could debug it with PDB
correctly, but couldn't have it worked properly in emacs.
The version of emacs on my machine is:
GNU Emacs 22.1.1 (i386-mingw-nt5.1.2600) of 2007-06-02 on RELEASE.
After inputting "M-x pdb", and then "python -m c:\python25\Lib\pdb.py
test.py", I got the following error message:
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
Current directory is c:/python25/Lib/
Traceback (most recent call last):
File "c:\python25\lib\runpy.py", line 85, in run_module

The debug message was not displayed immediately when the debug command

Using "python c:\python25/Lib/pdb.py test.py", I got:

Any suggection will be appericiated. Thank you.

default-directory is set to c:/python25/Lib from your previous attempt.
Specifying the path to test.py should work:
python c:\python25/Lib/pdb.py c:/yourpath/to/test.py
If you don't specify the path to test.py you need to make sure that
default-directory is the directory test.py is in, e.g., by doing M-x dired
in that directory first.
Why not just do:
pdb c:/yourpath/to/test.py
or
pdb test.py
?
as the default name for gud-pdb-command-name is just "pdb".

Thank you for your response.
But my emacs cannot execute such commands:
"apply: Searching for program: no such file or directory, pdb"
I copied "pdb.pyc" and "pdb.py" to "c:\Python25\".
Running "pdb.pyc test.py", the response was:
apply: Searching for program: no such file or directory, pdb.pyc
Running "c:\python25\Lib\pdb.pyc test.py", the response was:
"apply: Spawning child process: invalid argument"
With "pdb.py", I got the same result.

Did you set the path to pdb.py ?
(setq gud-pdb-command-name "~/bin/pdb.py")
Have you gdb installed on your system ?

They don't (Vista added them), but if that Python is Cygwin-compiled,
perhaps the Cygwin emulation of symbolic links could be involved.

Thank you for your help. I have tried all the method you suggested :)
I can have the PDB worked. I just cannot have it done this
interactively. I mean,
the debug message was not displayed immediately when the debug
command
was inputted, but was thrown out all together after the "q" was
given.:
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
Current directory is c:/
l
n
c
q
> c:\test.py(1)<module>()
-> i = 1
(Pdb) 1 -> i = 1
[EOF]

> c:\test.py(1)<module>()->None
-> i = 1
(Pdb) The program finished and will be restarted
> c:\test.py(1)<module>()
-> i = 1
(Pdb)
Debugger finished

Today I found a topic, which gives a clean description about this:
http://www.gnu.org/software/emacs/windows/faq7.html#subproc-buffer
The output of PDB is buffered (by python.exe, not emacs) and cannot
been displayed.
Now it works with this command:
python -u -m pdb test.py
-u : unbuffered binary stdout and stderr (also PYTHONUNBUFFERED=x)
see man page for details on internal buffering relating to '-
u'
Many thanks to you, to Thierry Volpiatto, to Eli Zaretskii.
Thank you for your kindly help :)

Perhaps then we should make the change below. Does this workd for you?
Does it work for anybody else with Python on Windows?
