PyQt is not accessible from python3

[Michael Helmling]

Binary package hint: python-qt4

With python3 and python-qt4 from current karmic packages, it's not possible to use the PyQt bindings, although PyQt supports python3 since version 4.5:
http://www.riverbankcomputing.co.uk/news/pyqt-45

But I get this:
Python 3.0.1+ (r301:69556, Apr 15 2009, 17:25:52)
[GCC 4.3.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import PyQt4
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named PyQt4

This is such a pity since python-3.x is _so_ much nicer than 2.x. ;-) Are there any problems with building pyqt for py3k?

[Michael Helmling (supermihi)]

I have just compiled PyQt4 (and before SIP 4, which is needed for compiling pyqt, and which is also not available in its python3 version in the ubuntu repos) without any problems on a current 9.10 beta machine.

[Philip Muškovac (yofel)]

Still doesn't work in lucid.

[Eric Lacombe (goretux)]

Hi,

I would like to know if this wish will be fulfill on Maverick?

Thanks.

[Scott Kitterman (kitterman)]

Maybe. Work on this is going on in Debian. It's not clear if we will get there in time for Maverick.

[Christian González (droetker)]

Doesnt work in maverick.

[Scott Kitterman (kitterman)]

That is correct. The packaging work to support this didn't get done for Maverick.

[IKT (ikt)]

As someone who was quite unhappy at this issue I was surprised to find it works in natty.

Was this fixed somewhere down the line?

[IKT (ikt)]

Wops, to early, the module seems to import, but it doesn't seem to do anything else :s

[Scott Kitterman (kitterman)]

We've made progress on the packaging in Natty. Sip4 is now packaged to
support Python3 and it's one of the prerequisites for PyQt4. It's not there
yet though.

[IKT (ikt)]

What else needs to be done, is there somewhere I can track progress?

[Christian González (droetker)]

Can I help too? - I need this.

[Scott Kitterman (kitterman)]

Look at what was done in the sip4 packaging. PyQt4 needs similar. If you
think you make sense of it and have questions or a proposed solution feel free
to ping me on #kubuntu-devel on freenode (I'm ScottK there) or here in the
bug.

[Dmitry Shachnev (mitya57)]

Since Oneiric is moving to Python 3 by default, we really need it.
The upstream PyQt supports Python 3 for a very long time.

Of course, we need a separate package like python3-qt4.

[Vitaly Chesnokov (chesn)]

BTW, SUSE already has python3-qt4 package:
http://pkgs.org/download/python3-qt4

Maybe, it's possible to make use of their experience?

[Scott Kitterman (kitterman)]

I've got it mostly done, but I'll have a look.
