I am faced with a situation wherein since Ubuntu 12.04 uses Python 2.7 and Houdini 12.5 uses Python2.6, The trouble is with Installing PyQt4 for Houdini 12.5

I created the folders
/opt/hfs12.5.316.22/houdini/pyqt/houdini12/lib/python2.6
/opt/hfs12.5.316.22/houdini/pyqt/houdini12/include/python2.6
/opt/hfs12.5.316.22/houdini/pyqt/houdini12/share/sip
/opt/hfs12.5.316.22/houdini/pyqt/houdini12/bin
Downloaded the latest SIP version for Linux from the Riverbankcomputing website.

Installed updates from Terminal

sudo apt-get install python-qt4
sudo apt-get install g++

Then proceeded with the custom build of PyQt using the Houdini12 Hython interpreter.

/opt/hfs12.5.316.22/bin/hython configure.py –bindir=/opt/hfs12.5.316.22/houdini/pyqt/houdini12/bin –destdir=/opt/hfs12.5.316.22/houdini/pyqt/houdini12/lib/python2.6 –incdir=/opt/hfs12.5.316.22/houdini/pyqt/houdini12/include/python2.6 –sipdir=/opt/hfs12.5.316.22/houdini/pyqt/houdini12/share/sip

sudo make
sudo make install

sudo /opt/hfs12.5.316.22/bin/hython configure.py –bindir=/opt/hfs12.5.316.22/houdini/pyqt/houdini12/bin –destdir=/opt/hfs12.5.316.22/houdini/pyqt/houdini12/lib/python2.6 –plugin-destdir=/opt/hfs12.5.316.22/houdini/pyqt/houdini12/plugins –sipdir=/opt/hfs12.5.316.22/houdini/pyqt/houdini12/share/sip –assume-shared
This is SIP 4.14.5 for Python 2.6.4 on linux2.
Usage: python configure.py

configure.py: error: no such option: –plugin-destdir

sudo /opt/hfs12.5.316.22/bin/hython configure.py –bindir=/opt/hfs12.5.316.22/houdini/pyqt/houdini12/bin –destdir=/opt/hfs12.5.316.22/houdini/pyqt/houdini12/lib/python2.6 –sipdir=/opt/hfs12.5.316.22/houdini/pyqt/houdini12/share/sip –assume-shared
This is SIP 4.14.5 for Python 2.6.4 on linux2.
Usage: python configure.py

sudo make
sudo make install

export PYTHONPATH=/opt/hfs12.5.316.22/houdini/pyqt/houdini12/lib/python2.6

sudo cp /opt/hfs12.5.316.22/houdini/help/hom/cookbook/pyqt/part2/pyqt_thread_helper.py /opt/hfs12.5.316.22/python/lib/python2.6/site-packages

echo $PYTHONPATH
/opt/hfs12.5.316.22/houdini/pyqt/houdini12/lib/python2.6




The only change I did was to edit/remove the –plugin-destdir and the –assume-shared flags due to the above errors.

Iḿ not sure what else I have to do to get PyQt4 to work with Houdini.

Any help would be greatly appreciated.

Thanks,

Nikhil.

Looks like u used options plugin-destdir and assumed shared to compile sip. It s only available for the pyqt compilation.

And be sure to be in the right folder ,sine there s a configure.py for sip and another inthe pyqt distrib before running hython

I installed Ubuntu and followed my updated post (read about sipconfig)

and it worked
from PyQt4.QtCore import *
returns no error

let me know if u have problems
Cheers

Hi,

Thanks for your reply and for the further steps you suggested regarding the sigconfig too.

I also included the line to appened the sipconfig path within the configure.py within the PyQt folder. This time around repeated the SIP make and install steps and then moved into the PyQt directory and ran the following:

MacBookPro:~/openSource/PyQt$ sudo /opt/hfs12.5.316.22/bin/hython configure.py –bindir=/opt/hfs12.5.316.22/houdini/pyqt/houdini12/bin –destdir=/opt/hfs12.5.316.22/houdini/pyqt/houdini12/lib/python2.6 –plugin-destdir=/opt/hfs12.5.316.22/houdini/pyqt/houdini12/plugins –sipdir=/opt/hfs12.5.316.22/houdini/pyqt/houdini12/share/sip –assume-shared
Error: Make sure you have a working Qt qmake on your PATH or use the -q
argument to explicitly specify a working Qt qmake.

This is the error I received while trying to install PyQt using the Hython interpreter. Would you have any suggestions?

Thanks again.

Cheers,

Nikhil.

The error looks like either
-qt doesnt exist on your system : if u are on ubuntu as u suggested, try to instll qt4 with the apt-get command (google a bit if not familiar with it). Before that u can use the command apt-cache i think to list available packges for ur system.

- If it is installed but not in your path, add it in your path as suggested by the error.
export PATH=your-path:$PATH

Thanks so much for the tip.

I got PyQt too to compile properly after installing QT using this line of code:

sudo apt-get install libqt4-*

Now my custom PyQt tools work perfectly within Houdini.

Appreciate all the help!
