Edit: This guide is now fairly out of date, I strongly recommend people move to Ubuntu 12.04 LTS where pyqt4 and qt4 designer are already packaged, no compiling required!

Hopefully this will give it a bit more coverage on the interwebs:

1) Before compiling any software ensure build-essential is installed

sudo apt-get install build-essential

(11.10 users go to step 3)

2) Open the synaptic package manager and install python 3.2

3) Next open a terminal emulator and type:

sudo apt-get install libqt4-dev

4) Download the program SIP from:


5) extract the folder using tar -xzf sip-X.XX.X.tar.gz, cd into folder.

6) in terminal emultator, type:

python3.2 configure.py


sudo make install

SIP should now be installed.

If you receive the error:

siplib.c:20:20: fatal error: Python.h: No such file or directory
compilation terminated.
make[1]: *** [siplib.o] Error 1

You will need to install python3.2-dev (sudo apt-get install python3.2-dev) and repeat the above.

7) install pyqt4 with the command:

sudo apt-get install python-qt4 qt4-dev-tools python-qt4-dev pyqt4-dev-tools

You can then try step 8.

If that didn’t work for you, download pyqt4 from: http://www.riverbankcomputing.co.uk/software/pyqt/download

Untar and install pyqt4 the same way you installed SIP.

1) in terminal extract the folder using tar -xzf PyQt-x11-gpl-X.X.X.tar.gz and then cd into the folder.

2) in terminal emultator, type:

python3.2 configure.py


sudo make install

8) You should then be able to type in terminal (case sensitive):


>>import sys

>>from PyQt4 import QtGui

If this works without error PyQt4 is installed and works with Python 3.2! Hurrah!
