[python-uk] RaspberryPi related request for help

[René Dudfield]

Ok, here's a start... I gathered more information, and found an
alternative[0].


Seems i2c-tools needs to make a new release first? That would be the place
to ask first. http://www.lm-sensors.org/browser/i2c-tools/trunk

Then the Debian package can be updated:
    https://packages.debian.org/wheezy/python-smbus

By posting a bug report here, which will alert the maintainers.

https://bugs.debian.org/cgi-bin/pkgreport.cgi?pkg=python-smbus;dist=unstable

You can see all the Debian package info here, like the change log, the
debian packaging files, and maintainer email addresses:
    https://packages.qa.debian.org/i/i2c-tools.html

They last made a release on March 8th, so they would seem to be responsive.



Debian packages can be made with patches on top of upstream releases if
needed. Which they have done already in this package.

You need to have a separate .diff file patch for the feature. Which you can
get from here: http://www.lm-sensors.org/changeset/6267/i2c-tools/trunk

See the Debian python packaging guide:
https://wiki.debian.org/Python/Packaging
I'm sure the maintainers would be happy to help someone out if they have
questions.


best,


[0] There's a cffi implementation with python 3 support. That can be pip
installed, so there is no need for a debian package.
https://github.com/bivab/smbus-cffi

ps. what's the benefit of conda (to people, not to the company selling it)
now that there are wheels and devpi? Seems to only divide the python
community and add more confusion now.
