BODY { font-family:Arial, Helvetica, sans-serif;font-size:12px; }This is the result of searching for that library, also i dont get the error when running python normally only when its embeded, so something must be different when you embed for the error to only occur when when running code in the embeded version. locate /usr/lib/libpyglib /usr/lib/libpyglib-2.0-python2.6.so.0 /usr/lib/libpyglib-2.0-python2.6.so.0.0.0 I have double checked and i have all the python-dev packages and all the dev packages for things like gtk and the other libraries i require and have search for the .h files and they seem to be present and in place. On Fri 29/10/10 8:39 AM , Jamie Kirkpatrick jkp(a)kirkconsulting.co.uk sent: Well, do you have that library on your system? The problem is that you are loading a Python module that uses a C extension module under the hood so your python runtime is looking to load in that library as you import that module but its not finding it. How have you "installed" the gtk module so your embedded Python can see it? I've never embedded Python in a C application before but I'll do what I can to help you :) BTW: A great site for quick answers to questions like this (if you don't already know it) is stackoverflow.com [1] Jamie On 28 October 2010 22:46, Oliver Marks wrote: Hi i am a new member on this list and thought if some people may be able to enlighten me to the error below ?

PyCon co-presenter sought for OpenGL talk
by Jonathan Hartley Oct. 29, 2010

Oct. 29, 2010

Hey folks, I'm searching for a co-presenter for a talk I've proposed at PyCon (Atlanta 2011). The title is 'Algorithmically Generated OpenGL Geometry', and it's currently envisioned as an improved version of a talk I already gave at EuroPython under the title 'Hobbyist OpenGL : Flying High' (blogged with screenshots here: http://tartley.com/?p=1207) The talk presents a simple and Pythonic way to model 3D polyhedra, shows how to convert those into the arrays that OpenGL expects, and then plays around with a bunch with algorithms that act on the polyhedra class, to generate fun & interesting virtual sculptures. I'd like a co-presenter simply because I think it would be more fun to prepare and present with someone else than by myself, plus of course the talk will benefit from the imagination of two people being applied to it. People I asked to date are either too busy or shy or can't attend, so I thought I'd try this more scattershot approach. If you have any interest (even if you have reservations, e.g. would like to work on it, but are too shy to present, or would like to present, but don't have much time to help prepare), then let me know.

Next Cambridge & East Anglia Meeting: Tue 2nd November
by Tony Ibbs Oct. 26, 2010

Oct. 26, 2010

As announced on the CamPUG Google Group: The next meeting will be a talks meeting, Tuesday 2nd November, 7.30pm at RealVNC (http://tinyurl.com/realvncoffices). I believe we have one offer of a talk, and going by previous meetings other people will have things too. Meetings after that should be: * Tuesday 7th December, a dojo meeting * notionally Tuesday 4th January (2011), but I'd propose actually having the January meeting on the 11th. This would be a talks meeting * Tuesday 1st February, another dojo meeting. If anyone wants to suggest different dates for January/February, please do so. Tibs

processing input from multiple files
by Christopher Steele Oct. 15, 2010

Oct. 15, 2010

Hi I've been trying to decode a series of observations from multiple files (each file is a different time) and put each type of observation into their own separate file. The script runs successfully for one file but whenever I try it for more they just overwrite each other. I'm new to python and I'm not sure how to go about efficiently running through the process once and then appending to the output file for all other input files. Has anyone done something similar to this before? cheers Chris

Fwd: [PyCon-Organizers] PyCon 2011 Poster Session CFP Now Open!
by Rami Chowdhury Oct. 11, 2010

Oct. 11, 2010

==== PyCon 2011 Call for Posters ==== PyCon 2011 will be held March 9th-17th, 2011 in Atlanta, Georgia, USA. (Home of some of the best southern food you can possibly find on Earth!) The PyCon conference days will be March 11-13, preceded by two tutorial days (March 9-10), and followed by four days of development sprints (March 14-17). This is the second year that PyCon is offering a poster pession. A poster is a 4' x 4' graphical summary of the key points about your project, and a poster session provides another way of presenting that encourages more one-on-one communication between the presenter and the audience. Poster sessions are particularly suited for topics of interest to a subset of the community and/or presenters who are more comfortable interacting with smaller groups. Poster sessions also are a great incubator for further hallway track discussions. Poster proposals will be accepted on a rolling basis until January 19 or we reach the limit of 35 posters. For general information on the poster session visit the PyCon site at http://us.pycon.org/2011/speaker/posters/ , for a list of last year's posters go to http://us.pycon.org/2010/conference/posters/accepted/, or see the full CFP for poster proposals at http://us.pycon.org/2011/speaker/posters/cfp/. To submit a poster proposal use the PyCon speaker submission system found at http://us.pycon.org/2011/speaker/ See you in Atlanta!
