Hi Andrew.
As I'm not running SUSE, the packaging is different
because it has been independently packaged by a SUSE
user for use on non-SUSE platforms.
The dual versions of qrtools.py is not a problem
as it merely means that python will use the version
that matches its own environment.
I would suggest the first thing to do is to run
python from a terminal session, and make a note
of what version is configured as the default.
("rpm -q python" should also be informative.)
It could be that SUSE has python 3.3 as the default.
If multiple versions of python are installed, you
will find that the versions probably have symlinks
to names like python2, python2.7, python3, python3.3
etc.
That would allow you to merely edit the /usr/bin/qtqr
script file and set the python version explicitly to
python2.7 for instance.
#!/bin/sh
exec /usr/bin/python /usr/bin/qtqr.py "$@"
would become:
#!/bin/sh
exec /usr/bin/python2.7 /usr/bin/qtqr.py "$@"
You may also need to make an alteration to the
/usr/bin/qtqr.py script, and replace
#!/usr/bin/env python
with
#!/usr/bin/env python2.7
Looking at the qtqr.py script, there are not
a lot of libraries being included.
sys, os and math are all standard python
libraries. gtk, PyQt4 and qrtools however
would need to be installed.
Please note however, that I only dabble with
python, I'm certainly no expert.
See how you go.
Regards,
Morrie.

Ok Morrie,
I had a look myself thanks to your guidance:
andrewg@andrewg:/> rpm -ql python-qrtools
/
/usr
/usr/lib
/usr/lib/python2.6
/usr/lib/python2.6/dist-packages
/usr/lib/python2.6/dist-packages/qrtools.py
/usr/lib/python2.7
/usr/lib/python2.7/dist-packages
/usr/lib/python2.7/dist-packages/qrtools.py
/usr/share
/usr/share/doc
/usr/share/doc/python-qrtools
/usr/share/doc/python-qrtools/changelog.gz
/usr/share/doc/python-qrtools/copyright
/usr/share/python-qrtools
and it is definitely in the dist-packages directories but does not work. Is it
confused by the two dist-packages addresses? Should I delete the file from the
python2.6/dist-packages location?
Thanks
Andrew

Hi Andrew.
Just tried the same on my Fedora 20 box at home, and
had exactly the same error.
The problem is easily discovered using:
rpm -ql python-qrtools
/qrtools.py
/usr/share/doc/python-qrtools
/usr/share/doc/python-qrtools/LICENCE
/usr/share/doc/python-qrtools/copyright
You will not that the qrtools.py ends up under the
root directory, not in the usual site-packages
directory /usr/lib/python2.7/site-packages/
I'm guessing the reason is that Fedora 20, and
probably Suse too, have python versions 2.7 and 3.3
both simultaneously installed, so the packager took
the lazy way out, leaving it up to the end user
to put qrtools.py in in a more sensible place.
I just moved qrtools.py to the above site-packages
directory, and away it went.
(It also doesn't seem to work under python3, probably
as the various other python modules are not present
under the /usr/lib/python3.3/site-packages/ directory.)
So give it a try and see how you go.
Regards,
Morrie.

Subject: QR code generator
Hi all,
Could I please get some advice concerning my failure to get the QtQR program
running under SuSe 13.1
I have downloaded the rpm and installed qtqr as well as python-qrtools
I have no joy from the GUI "run" process
and from the cli I get
andrewg@andrewg:~> /usr/bin/qtqr
Traceback (most recent call last):
File "/usr/bin/qtqr", line 15, in <module>
from qrtools import QR
ImportError: No module named qrtools
andrewg@andrewg:~>
I tried modprobe but that command no longer works.
I have a project where I need to generate around 350 different QR codes, all of
the same format.
And then I need to print them in such a way as to recognise each label easily
to correctly locate them.
Thanks
Andrew Greig
