wxPython 2.9 for Ubuntu 12.04

[Bruce Sherwood]

I see that there isn't a package for wxPython 2.9 for Ubuntu 12.04. If I were to attempt to build 2.9 from source, what version of wxwidgets is required? Is wxwidgets 2.8 sufficient (it's the one available on Ubuntu 12.04).

And there probably won't be. I don't have time nor desire to maintain
the .deb packaging scripts, and the Debian/Ubuntu folks don't seem to
care about providing binaries for a release from the "development"
release series even though some would say it is better and more stable
than the last "stable" release.

No, you need to use a matching version of wxWidgets. You're in luck
though, as the wxWidgets code is also in the wxPython-src tarball, and
wxPython's build-wxpython.py script will also build wxWidgets for you.
Be sure to get and apply the 2.9.4.1 patch that I mentioned yesterday
though.

I built and installed wxPython 2.9 on Ubuntu 12.04, with the recent
patch, but when I import wx I get this error:

File "userpoll.py", line 2, in <module>
from wxpoll import *
File "/home/bruce/Documents/wxPython/wxpoll.py", line 2, in <module>
import wx
File "/usr/local/lib/python2.7/dist-packages/wx/__init__.py", line
45, in <module>
from wx._core import *
File "/usr/local/lib/python2.7/dist-packages/wx/_core.py", line 4, in <module>
import _core_
ImportError: libwx_gtk2u_adv-2.9.so.4: cannot open shared object file:
No such file or directory

However, I find this file:

/usr/local/lib/libwx_gtk2u_adv-2.9.so.4

Any idea what I could be doing wrong?

You need to tell the system to look for shared libs in that path. You
can do that by setting LD_LIBRARY_PATH or you can edit /etc/ld.so.conf
and then run ldconfig to update the system search paths.

Thanks! Silly me, I thought that /usr/local/lib was on the library
search path by default. It all works now.
