How to configure PyQt4 for Python 3 in Ubuntu?

Question

This question was originally asked in askubuntu.com but got no attention so I think maybe this is a better place to ask.

I installed PyQt4 with synaptic.

I'm using Python3 so I need to configure the path for PyQt4 in eclipse, but it seems synaptic only installed PyQt4 for python 2 since I only found relative files and folders under python 2.6 and 2.7.

So how can I make PyQt4 to work with Python 3 and eclipse ?

Thanks.

UPDATE：

I tried to configure it following this post: http://ubuntuforums.org/showthread.php?p=10914908#post10914908

But after following all the instructions without any error occurs in the way, I get error from running this code in python 3.2:

>>> import PyQt4 

The error message is :

Traceback (most recent call last):   File "<stdin>", line 1, in <module> ImportError: No module named PyQt4 

But the strange thing is that the same code results NO error in python 2.7 (I have both 2.7 and 3.2 installed on my machine)

Answer 1

You should be able to install the python 3 version of PyQt4 in ubuntu. Open a terminal and type:

sudo apt-get install python3-pyqt4 

This way you don't have to compile Qt4 from source. I have also tested this and pyqt4 works with python3.

Install packages needed for compiling (I am not sure these all are needed):

sudo apt install build-essential python3-dev libqt4-dev 

Download sources of the latest SIP - sip-4.12.4.tar.gz (Linux, UNIX, MacOS/X source).

Unpack them and enter the directory:

vic@wic:~/Desktop/sip-4.12.4$ python3 configure.py  This is SIP 4.12.4 for Python 3.2 on linux2. The SIP code generator will be installed in /usr/bin. ...

Download the sources of the latest PyQt - PyQt-x11-gpl-4.8.5.tar.gz (Linux, UNIX source), and install it:

vic@wic:~/Desktop/PyQt-x11-gpl-4.8.5$ python3 configure.py  Determining the layout of your Qt installation...

Note, that I am launching python3 instead of python.
