[wxpython-users] WXU_2.8 not defined in file libwx_gtk2u_core-2.8.so.0

[ja...@email.arizona.edu]

When I import wx I get this error message.

Traceback (most recent call last):
File "main.py", line 1, in <module>
import wx
File "/usr/lib/python2.5/site-packages/wx-2.8-gtk2-unicode/wx/__init__.py",
line 45, in <module>
from wx._core import *
File "/usr/lib/python2.5/site-packages/wx-2.8-gtk2-unicode/wx/_core.py", line
4, in <module>
import _core_
ImportError: /usr/lib/python2.5/site-packages/wx-2.8-gtk2-unicode/wx/_core_.so:
symbol _ZN5wxApp10InitializeERiPPw, version WXU_2.8 not defined in file
libwx_gtk2u_core-2.8.so.0 with link time reference

I don't have a clue what this means, I've downloaded and installed several
things several times, wxWidgets, glib, wxPython, gtk, maybe others. All of
them from source and from synaptic(I'm using Ubuntu 8.04) except for gtk which
won't let me install it from source until I remove the version I installed from
the Ubuntu repositories which demands that I remove every program dependent on
glib if I do so from synaptic, even though I already have a more recent version
then the one I'm removing.

I also thought the u in WXU and gtk2u might suggest something to do with unicode
so I configured wxWidgets and wxPython with --enable-unicode.

All in all I've been at it for a while, it's late, and I have gotten absolutely
nowhere.

Hi,

> ___________

I just followed the directions on the wiki and it worked for me:
http://wiki.wxpython.org/InstallingOnUbuntuOrDebian

I don't think the key is required any more though as I always get an
error from the repositories that I add. The ones in the official Ubuntu
repositories seem to work fine, so I just use Apt-get to install it.
Unless you have a compelling reason to, you probably don't need to build
it yourself.

It probably means that the wx libs being found at runtime are not the
same ones that wxPython was built with.

Hi,
I have the similar problem. Whenever I import wx, the message error appear
like this:

>>> import wx

Traceback (most recent call last):

I have installed the following:

libgtkspell-3-0
libgtksourceview-3.0-0
libgtksourceview-3.0-common
libgtkmm-3.0-1
libgtkspell-3-0

I'm using Ubuntu 12.04 LTS (precise), which doesn't have support in
http://wiki.wxpython.org/InstallingOnUbuntuOrDebian
So all I have done is installing via "Synaptic Package Manager".


Please help. note: I'm a newbie for linux/unix, so please kindly describe
the solution in detail.


The other version seems to not be my choice. I have some detail below (u can
skip it XD).

--When I install wxpython in version 2.6, the "import wx" did work, but the
version was too old, I can't use that. (It give me a compile error for the
source code I'm working on, because my colleagues use the higher version
2.8) . I've tried to compile 2.8 myself from the sourcecode but it
complain about opengl, and I did tried to do my best, and finally gave up.
I've also tried to build 2.9 (not official version), I compiled successfully
without problem. but when I use this version to run the program which wrote
by my colleague. There is some kind of exception, some kind of error from
wx itself. So I think choose stick with version 2.8--

Best Regard

Usually that means that there is a mismatch between the wxWidgets
library and wxPython. That should not happen with packages installed
from the repository unless the package manager has done something weird,
but double check that the python-wxgtk2.8 and libwx* packages all have
the same version number.

You may also want to run ldd on one of the wxPython .so files to see
which wx libraries it is loading dynamically. It's possible that it is
finding the wrong ones, especially if you have tried building your own.

Using the 11.04 packages from there should still work okay on a 12.04
system, but it should not be needed.
