py25-wxpython causes an error message in the Python interactive interpreter help().

[paidhi@…]

After installing py25-wxpython trying to show all available modules in the Python interpreter fails with an error message.

Here is how to reproduce it:

$ python
Python 2.5.2 (r252:60911, Aug  8 2008, 22:25:12) 
[GCC 4.0.1 (Apple Inc. build 5484)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> help()

Welcome to Python 2.5!  This is the online help utility.

If this is your first time using Python, you should definitely check out
the tutorial on the Internet at http://www.python.org/doc/tut/.

Enter the name of any module, keyword, or topic to get help on writing
Python programs and using Python modules.  To quit this help utility and
return to the interpreter, just type "quit".

To get a list of available modules, keywords, or topics, type "modules",
"keywords", or "topics".  Each module also comes with a one-line summary
of what it does; to list the modules whose summaries contain a given word
such as "spam", type "modules spam".

help> modules

Please wait a moment while I gather a list of all available modules...

My environment:

MacOS 10.5.4

$ port version
Version: 1.600

$ port installed |grep wx
  py25-wxpython @2.8.8.1_0 (active)
  wxWidgets @2.8.8_0 (active)

After uninstalling py25-wxpython it works.

Thanks for any help,

I just tried with version 2.8.9.1 of py25-wxpython and it simply hangs.

I notice that this ticket is 5 years old and probably a lot has changed in the meantime. I don't experience the problem with the new 64-bit py27-wxpython-2.8 +gtk, but I most probably need a volunteer to test it with py25-wxpython-2.8 +carbon on an "outdated OS".

[mojca (Mojca Miklavec)]

I tested this with py25-wxpython-2.8 +carbon on 10.6 and it seems to work. What fails is

help> wx
problem in wx - <type 'exceptions.ImportError'>: dlopen(/opt/local/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/wx-2.8-mac-unicode/wx/_core_.so, 2): no suitable image found.  Did find:
	/opt/local/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/wx-2.8-mac-unicode/wx/_core_.so: mach-o, but wrong architecture

but honestly I have no clue how to properly run Python as i386 in 10.6 and this is also out of scope for this ticket.

I'm closing the ticket, but if anyone can still reproduce the error or has other problems with it, don't hesitate to reopen the ticket.
