** Summary changed:
- not possible to switch between python-wxgtk2.6 or python-wxgtk2.8 as the
default wxPython in Jaunty
+ sudo update-alternatives does not configure the default python-wxgtk in Jaunty
** Description changed:
In Jaunty, when both python-wxgtk2.6 and python-wxgtk2.8 are installed, this
happens by default:
>>> import wx
>>> wx.VERSION
(2, 6, 3, 2, '')
In Intrepid, this happens by default:
>>> import wx
>>> wx.VERSION
(2, 8, 8, 0, '')
- The behaviour in Jaunty looks like a bug to me.
+ This switch might be unexpected by programs which run fine under
+ intrepid and depend on 2.8. (In the ideal scenario they should choose
+ the right version with wxversion.)
Moreover in Jaunty 2.8 seems to be configured as the default:
$ ls /etc/alternatives | grep wx
wx2.5.pth
wx2.6.pth
$ sudo update-alternatives --config wx2.6.pth
[sudo] password for stani:
Er zijn 2 alternatieven die 'wx2.6.pth' voorzien.
Selectie Alternatieven
-----------------------------------------------
*+ 1 /usr/lib/wx/python/wx2.8.pth
2 /usr/lib/wx/python/wx2.6.pth
So with "update-alternatives" I can't select that "import wx", imports
wxPython 2.8
+
+ In Debian this looks right:
+ $ sudo update-alternatives --config wx.pth
+ There are 2 choices for the alternative wx.pth (providing
/usr/lib/wx/python/wx.pth).
+
+ Selection Path Priority Status
+ ------------------------------------------------------------
+ * 0 /usr/lib/wx/python/wx2.6.pth 26 auto mode
+ 1 /usr/lib/wx/python/wx2.6.pth 26 manual mode
+ 2 /usr/lib/wx/python/wx2.8.pth 25 manual mode
+
+ When 2 is selected, wx 2.8 will be the default version (in Debian):
+ >>> import sys, wx
+ >>> print wx.VERSION
+ (2, 8, 7, 1, '')
+ >>> print sys.path
+ ['', '/usr/lib/python2.5', '/usr/lib/python2.5/plat-linux2',
'/usr/lib/python2.5/lib-tk', '/usr/lib/python2.5/lib-dynload',
'/usr/local/lib/python2.5/site-packages', '/usr/lib/python2.5/site-packages',
'/usr/lib/python2.5/site-packages/PIL',
'/usr/lib/python2.5/site-packages/gst-0.10', '/usr/lib/pymodules/python2.5',
'/usr/lib/pymodules/python2.5/gtk-2.0',
'/usr/lib/python2.5/site-packages/wx-2.8-gtk2-unicode']
In Jaunty if I look to wx.pth:
$ cat /usr/lib/python2.6/dist-packages/wx.pth
wx-2.8-gtk2-unicode
In Jaunty many wx*.pth are added in comparison to Intrepid (but this is
probably irrelevant):
$ locate .pth | grep wx
/etc/alternatives/wx2.5.pth
/etc/alternatives/wx2.6.pth
/usr/lib/python2.5/site-packages/wx-2.8-gtk2-unicode.pth
/usr/lib/python2.5/site-packages/wx.pth
/usr/lib/python2.5/site-packages/wx-2.8-gtk2-unicode/wx.pth
/usr/lib/python2.6/dist-packages/wx-2.8-gtk2-unicode.pth
/usr/lib/python2.6/dist-packages/wx.pth
/usr/lib/python2.6/dist-packages/wx-2.8-gtk2-unicode/wx.pth
/usr/lib/wx/python/wx2.8.pth
/usr/share/pyshared/wx-2.8-gtk2-unicode.pth
/usr/share/pyshared/wx-2.8-gtk2-unicode/wx.pth
/var/lib/dpkg/alternatives/wx2.5.pth
/var/lib/dpkg/alternatives/wx2.6.pth
In Intrepid this gives:
$ locate .pth | grep wx
/etc/alternatives/wx2.4.pth
/etc/alternatives/wx2.5.pth
/usr/lib/python2.4/site-packages/wx.pth
/usr/lib/python2.5/site-packages/wx.pth
/usr/lib/wx/python/wx2.6.pth
/usr/lib/wx/python/wx2.8.pth
/var/lib/dpkg/alternatives/wx2.4.pth
/var/lib/dpkg/alternatives/wx2.5.pth
In Jaunty:
>>> import sys
>>> sys.path
['', '/usr/lib/python2.6', '/usr/lib/python2.6/plat-linux2',
'/usr/lib/python2.6/lib-tk', '/usr/lib/python2.6/lib-old',
'/usr/lib/python2.6/lib-dynload', '/usr/lib/python2.6/dist-packages',
'/usr/lib/python2.6/dist-packages/Numeric',
'/usr/lib/python2.6/dist-packages/PIL',
'/usr/lib/python2.6/dist-packages/gst-0.10',
'/var/lib/python-support/python2.6',
'/usr/lib/python2.6/dist-packages/gtk-2.0',
'/var/lib/python-support/python2.6/gtk-2.0',
'/usr/lib/python2.6/dist-packages/wx-2.6-gtk2-unicode',
'/usr/lib/python2.6/dist-packages/wx-2.8-gtk2-unicode']
In Intrepid:
>>> import sys
>>> sys.path
['', '/usr/lib/python2.5', '/usr/lib/python2.5/plat-linux2',
'/usr/lib/python2.5/lib-tk', '/usr/lib/python2.5/lib-dynload',
'/usr/local/lib/python2.5/site-packages', '/usr/lib/python2.5/site-packages',
'/usr/lib/python2.5/site-packages/Numeric',
'/usr/lib/python2.5/site-packages/PIL',
'/usr/lib/python2.5/site-packages/gst-0.10',
'/var/lib/python-support/python2.5',
'/var/lib/python-support/python2.5/gtk-2.0',
'/usr/lib/python2.5/site-packages/wx-2.8-gtk2-unicode']
So in Jaunty both wx-2.6 and wx2.8 are added to the sys.path, while in
Intrepid only wx-2.8 was present.
To me it seems like a bug that both wx 2.6 and 2.8 are in sys.path
See also this discussion on the wxpython users mailing list upstream:
http://thread.gmane.org/gmane.comp.python.wxpython/70340
Some wxpython programs are now showing bugs as they are not compatible
anymore with wxpython2.6
- If possible, I would like to see this fixed that in Jaunty (like in
- intrepid) wxPython 2.8 is the default if both 2.6 and 2.8 are installed
- or that at least the user can configure it in a way.
+ If possible, it would be nice that in Jaunty (like in intrepid) wxPython

+ update-alternatives should work for wxpython, so that at least the user
+ can configure it the default wxpython version.
