Python on the Power PC

[Peter Milliken]

Hi,

I (think I have :-)) installed Python on my Pocket PC (obtained from
http://fore.validus.com/~kashtan/).

There were Tkinter binaries with it so I installed those as well. When I
attempt to run the most simplistic of python programs using Tkinter, I get
an error message stating that Python can't find any tkinter module.

Any ideas what I have done wrong anybody?

Thanks
Peter

import Tkinter

if __name__ == '__main__':
root = Tkinter.Tk()

root.title('Hel lo World?')

root.mainloop()

what does "import _tkinter" say ?

where is the _tkinter.so module (or whatever that's called on the pocket pc,
or power pc, or what it is you're using) installed ? what is sys.path set to ?

running

python -vv -c 'import _tkinter'

might provide you with additional clues.

Are you sure it didn't say "_tkinter" was what it couldn't find?

On my Windows system the Tkinter.py file tries to import an extension
(compiled C) module called _tkinter (provided as _tkinter.dll) that
provides the low-level Tkinter functionality. It's likely that that's
missing.

Re: Python on the Power PC

Unfortunately I am completely new to using the Pocket PC - the Python error
message appear to come up in 2 "waves" or screens - the first screen
contains the error message re can't find tkinter and is only visible for a
fraction of a second (repeated running and trying to get the eyes to focus
on each bit of information is very difficult! :-)) the second screen just
says

Traceback (inner most last):
<NULL> <NULL>

Unfortunately I can't work out any way to access the first screen to get the
exact message.

Also, I don't have any command line interface on the Pocket PC to follow
Fred's suggestion and run Python with command line arguments set. I seem to
be limited to just running a .py file from the File Explorer.

In the "Program Filess\Python\L ib" path there is a _tkinter file but it is a
..pyd not a .dll.

Re: Python on the Power PC

I'm using the same distribution (or at least that is what I started
with). Try using the following sitecustomize.p y file:

###### sitecustomize.p y ######
import sys
syspath = sys.path
libpath = '\\Program Files\\Python\\ Lib'
syspath.append( libpath+'\\lib-tk')
sys.path = none
sys.path = syspath
############### ###############

You will need to extract the python23.zip into \Program
Files\Python\Li b, then add the sitecustomize.p y file to the same
directory. Then Python should be able to find the Tkinter module that
it is complaining about.

Re: Python on the Power PC

Thanks for the reply Matt - you must have customised things though from the
distribution because this can't (and doesn't! :-)) work i.e. I have
(already) placed the python23.zip into \Program Files\Python\Li b but there
is no lib-tk off that point (which is what I believe the .append instruction
does in the customize script).

In fact, looking at my Python24 installation on my PC, I can see a lib-tk
directory off c:\Python24\Lib - but there is no such directory on my Pocket
PC - can I just "copy" this directory directly onto my Pocket PC? <see
below!>

OK, copying the lib-tk directory over to my Pocket PC seems to make the file
work - thanks for the help! :-)

Re: Python on the Power PC

Nope, spoke too soon! The Pocket PC seemed to be doing something and I
thought it was OK - obviously you can't just copy "lib-tk" into the Pocket
PC Python\Lib directory.

What else might I be missing?
