py2exe problems

[Alessandro Crugnola *sephiroth*]

Hi,
i'm trying to compile a .py script using py2exe into a win .exe file.
In that script i'm using xml.dom.minidom to parse an xml file (with the iso8859-1 encoding)

i've included in the setup command line the --packages encodings
but once i launch the exe file i receive this error in the console window:

Traceback (most recent call last):
File "<string>", line 51, in Notify
File "<string>", line 105, in __init__
File "WindowsSnippets.pyc", line 27, in __init__
File "WindowsSnippets.pyc", line 135, in loadXML
File "xml\dom\minidom.pyc", line 1915, in parse
File "xml\dom\expatbuilder.pyc", line 924, in parse
File "xml\dom\expatbuilder.pyc", line 207, in parseFile
LookupError: no codec search functions registered: can't find encoding

how can i solve the issue?
Mayn thanks

Which Python version are you using? 2.3 doesn't yet work correctly, but
2.2 should be ok.

The canonical test I use is to run the test_c14n.py test from the
PyXML source distribution through py2exe. It works for me, on Windows XP
Pro, SP 1, py2exe-0.4.1, Python 2.2.2, PyXML-0.8.3, with the command line
'python setup.py py2exe p encodings'
and this script:

from distutils.core import setup
import py2exe

setup(name='test_c14n', scripts=['test_c14n.py'], version='0')

If I don't include the '-p encodings' flag, the exe fails with this error:

C:\PyXML-0.8.3\test\dist\test_c14n>test_c14n
Traceback (most recent call last):
File "<string>", line 170, in ?
File "imputil.pyc", line 132, in _import_hook

File "<string>", line 128, in _process_result
File "xml\dom\ext\reader\__init__.pyc", line 20, in ?
LookupError: unknown encoding: utf-8

Can you try this and report back?

Thanks,

Thomas

PS: With Python 2.3 and py2exe-0.4.1, the traceback is this (even if -p
encodings had been given), note the different error message:

C:\PyXML-0.8.3\test\dist\test_c14n>test_c14n

Then I have no idea. Installing 2.2.3 instead of 2.2.2 is something I
cannot currently do (and I doubt it would help).

i've installed python 2.2.2 and now it seems working well.
Excuse, me but what are the issues with the other python versions?

So, there is a workaround for you, at least.

Sigh, in this case I should also install 2.2.3 and look into this.
The problem with 2.3 is that some imports seem to happen very early,
when the interpreter is initialized. And the py2exe import hook is
installed later, but it seems too late for warnings and encodings, at
least. Thanks for finding this.

Ok, I've installed 2.2.3 and verified the behaviour you observed.
And I have a workaround:

run the setup script with these options, and the test_c14n.py script
works as executable:

python py2exe --packages encodings --force-imports encodings

(I had nearly forgotten the force-imports option, and I still don't
remember exactly what it does :-)

This trick even helps with Python 2.3. I've added a comment to the web
page.
