Hi ... I've just compiled an untainted SVN and ... : cd src/optional/python-bindings/example_scripts export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python2.6/site-packages gnucash-env python simple_business_create.py sqlite3:///$HOME/test.gnucash Opening the test.gnucash file shows the correct entries. No use of the ParitIT stuff at all as some of the stuff on their site is a little out of date. The latest scripts should be in SVN r19582. Any idea why your modules are in /usr/lib/python2.5/site-packages/gnucash/ ? I found that using ipython and running scripts line-by-line (copy / paste style ) useful for debugging. I'm using Fedora12 by the way so not terribly familiar with Ubuntu. http://ipython.scipy.org/moin/ Ah, I just read your mail again! You're using gnucash 2.2.9? The latest unstable release is 2.3.15, which is what I have. Do think it's worth trying to get the old versions working when a new GnuCash release is imminent? There are new functions available in the new version that you may find useful.
