[gentoo-user] How to get rid of Python2 (where possible)
Hi,
would anybody please explain Portage's technique for selecting Python
versions for packages
from dev-python and similar.
I'd like to set up things such that Portage installs only the
Python-3.{3,4} version unless the
packages doesn't support Python-3.x
Currently I have
PYTHON_COMPAT=python2_7 python3_3 python3_4
PYTHON_TARGETS=python2_7 python3_3 python3_4
# PYTHON_SINGLE_TARGET=python2_7
PYTHON_SINGLE_TARGET=python3_3
in my /etc/portage/make.conf and portage itself is Python3-based.
I have to toggle the two PYTHON_SINGLE_TARGET lines depending
on some packages, e.g., dev-util/eric requires
PYTHON_SINGLE_TARGET=python3_3
which causes other packages not to install.
I have tried to remove python2_7 from PYTHON_TARGETS but then
I cannot re-install portage although it is based on Python3.
As you can see I am lost?
Many thanks for shedding some light onto these issues,
Helmut

Can anyone tell me why portage is insisting on upgrading me from

I would not expect portage to want to do this because:
1. opencv-2.4.8 is unstable (and I run a stable system)
2. opencv-2.4.5 is masked
Thank you,

Hello,
Can anyone tell me why portage is insisting on upgrading me from
opencv-2.4.5 to opencv-2.4.8?
It's not doing that.
You need opencv as it's a dep for something, and portage wants you to
have a version that's in the tree. The only stable version is 2.4.5 but
you have masked that in package.mask
So you have left portage no choice but to ask you to upgrade to a higher
version, all of which are marked ~arch. Therefore portage is giving you
the package.unmask entries to accomplish that and thereby asking you
pretty please to make everything consistent again on your machine.
Or you could remove that entry from package.mask and deal with what happens.
I would not expect portage to want to do this because:
1. opencv-2.4.8 is unstable (and I run a stable system)
2. opencv-2.4.5 is masked
Thank you,
Chris

It's quite funny actually :-) You did post emerge output using -t and it shows up at the top level which is a bit odd, it implies portage wants to update opencv anyway, not as a result of it being a dep. Are you sure you didn't keyword opencv and forget about it? grep -r opencv /etc/portage and to be complete, what are the deps for the package: equery depends opencv -- Alan McKinnon alan.mckin...@gmail.com

I agree it's odd and I agree it appears that portage isn't updating opencv because it's a dep. FWIW, an emerge -pv opencv wants to reinstall opencv-2.4.5 while an emerge -Dauv world wants to upgrade me to 2.4.8. grep -r opencv /etc/portage Yes, I was looking at that too.
