python-psyco is always installed in python2.6 dir

[Maarten Bosmans]

Even when I have only python 2.7 installed, psyco still installs in /usr/lib/python2.6/dist-packages/psyco
This causes the 'import psyco' executed from the default (2.7) python to throw an error.

not expected. you should include more information

[Maarten Bosmans (mkbosmans)]

> expected

Do you mean that python2.7 is supposed to pickup that library in usr/lib/python2.6, or that the files installed in /usr/share/pyshared/psyco/ suffice for all versions?

psyco does not support python.27 and probably never will

[Maarten Bosmans (mkbosmans)]

OK, that is clear thank you.

However, I don't see that fact reflected in the dependencies of python-psyco. It just has python >= 2.2. Am I missing something?

[Expired for psyco (Ubuntu) because there has been no activity for 60 days.]

[Maarten Bosmans (mkbosmans)]

Can the package dependencies of python-psyco be updated to reflect the fact that 2.7 is not supported?

We could make it depend on python2.6 instead of python, that's about it. It needs to still be installable, because it's still usable from Python 2.6, which we still have (just not as default).

This can of course be removed, too. We'll be dropping 2.6 before we open the p- archive.

[Marius B. Kotsbak (mariusko)]

Changing deps would not help me as I have both python 2.6.x and 2.7.x installed. For running "bitbake" without complaints about missing Psyco I changed the soft links in /usr/bin/ directory to python 2.6.

[Stefano Rivera (stefanor)]

You can safely ignore those warnings. bitbake doesn't depend on or recommend psyco.

[Marius B. Kotsbak (mariusko)]

Bitbake does not require it, but it is recommended for better performance (if not 2.7.x has better performance without...). From its manpage:

       -d, --disable-psyco
              disable using the psyco just-in-time compiler (not recommended)

[Scott Kitterman (kitterman)]

Last I checked, psyco didn't support Python 2.7 yet. If that's changed we can see about updating it.

Not closing this bug since I guess people might want to reintroduce it at some point - but since we don't have python2.6 in precise there's no point in keeping this.
