[Py2exe-users] py2exe, wxPython & zipextimporter error

[<ejo...@ea...>]

    I am off to sort of a rough start trying to use py2exe to build a
wxPython GUI and distribute it as a single Windows executable.  Running
the build seems to go OK, but when attempting to run the resulting
executable, I get the following error (put into a logfile by the exe):


C:\Python24\Lib\site-packages\py2exe\samples\singlefile\gui\dist\test_wx.exe\zipextimporter.py:82: DeprecationWarning: The wxPython compatibility package is no longer automatically generated or activly maintained.  Please switch to the wx package as soon as possible.

    I get the same behaviour trying to build the sample file
out of C:\Python24\Lib\site-packages\py2exe\samples\singlefile\gui

    I found this: http://article.gmane.org/gmane.comp.python.py2exe/1006
where Jimmy Retzlaff was responding to a similar question with a
somewhat similar error dump.  Jimmy provides a bare-bones wxPython
application and a setup.py file there which seems to have solved the
OP's problem, but I am seeing the same errors in even trying to do run
those two simple files unmodified. So, being quite green with py2exe, I'm
not sure where to turn next.  (Those two files are copied at the end of
this post for convenience - FYI, running the simple.py file directly,
works fine on my system with wxPython installed.)

    I guess I am also unclear on the idea or terminology of
building a single file executable. In setup.py in the
...\py2exe\samples\singlefile\gui dir, it has the following comments:

# Requires wxPython.  This sample demonstrates:
#
# - single file exe using wxPython as GUI.

and options that imply things should all be bundled into a single file:

setup(
    options = {"py2exe": {"compressed": 1,
                          "optimize": 2,
                          "ascii": 1,
                          "bundle_files": 1}},
    zipfile = None,
    windows = [test_wx],
    )


    But when the build is run, there are several things in the dist
directory, including msvcr71.dll.  That is because of licensing issues
with Microsoft?  Are there other options to explicitly direct py2exe to
link msvcr71.dll into the EXE?

    I found this article: http://www.devpicayune.com/entry/200701291417
which implies that the zipextimporter problem is actually stemming from
a missing msvcp71.dll (notice that's 'p', not 'r'). I tried to resolve
this by finding the DLL in the wxPython distribution
(C:\Python24\Lib\site-packages\wx-2.8-msw-unicode\wx\msvcp71.dll) and
manually copying it into the dist directory built by py2exe (next to
msvcr71.dll), but that doesn't change the behavior (i.e., you still get
an error and log file as above when running the exe).

    So... I'm not really sure what to try next. It's rather frustrating
that the distributed examples don't seem to be working. Is this implying
some sort of fundamental system incompatibility (wx version 2.8.0.1,
Windows 2000 Professional, python 2.4.4, py2exe 0.6.6) or am I simply
misunderstanding something?

    At this point I am more concerned with simplicity than efficiency.
That is, I want a single executable I can distribute that has pretty
much *everything* that would reasonably be required to execute my
wxPython GUI on a Windows system, I understand and accept that the exe
is going to be quite large.

    Working the tutorial found at: http://www.py2exe.org/index.cgi/Tutorial
pretty much makes sense to me and produces a console executable that
does what I would expect so, some things *are* working but I am running
into problems where wx is involved. Changing the setup call in the
tutorial to this:

setup(
    options = {
        "py2exe" : {
            "ascii"        : 1,
            "bundle_files" : 1,
        }
    },
    console=["foo.py"],
)

    still leaves these files in the dist directory, so I'm not clear on
exactly what they are or why they are not linked into the EXE if they
are required.

02/01/2007  01:19p              15,872 foo.exe
02/01/2007  01:19p           2,191,370 library.zip
03/16/2006  03:19p             348,160 MSVCR71.dll
10/18/2006  08:18a               4,608 w9xpopen.exe


    I guess the first step would be to get the two files in Jimmy's post
to work. Anyone else experiencing similar errors with those files? After
that, the sample under .../singlefile/gui ought to work.  Any general
advice for a noobie and information about options to explicitly bundle
DLL's and other files would be greatly appreciated. Links to other
tutorials also appreciated.

    Sorry this is a bit long - thanks for taking the time to read my post.

    Here's some basic information about my environment:

OS: Windows 2000 Professional

C:\Documents and Settings\ej\Desktop\src\dist_test>python

And here's Jimmy's two files I said I would include:

#=======================================================================
'simple.py'
import wx

class MyFrame(wx.Frame):
    def __init__(self, parent, title):
        wx.Frame.__init__(self, parent, -1, title, pos=(150, 150), 
            size=(350, 200))
        panel = wx.Panel(self)
        text = wx.StaticText(panel, -1, "Hello World!", (10, 10))

class MyApp(wx.App):
    def OnInit(self):
        MyFrame(None, "Simple").Show(True)
        return True

app = MyApp(redirect=False)
app.MainLoop()


#=======================================================================
'setup.py'
from distutils.core import setup
import py2exe

setup(
    script_args=['py2exe', '--bundle=1'],
    windows=["simple.py"],
    zipfile=None
)
