[gentoo-user] PYTHON_SINGLE_TARGET

[gentoo-user] PYTHON_SINGLE_TARGET

[Helmut Jarausch]

Hi,

suddenly emerging some packages like app-office/libreoffice or
media-gfx/blender fail due to

No Python implementation selected for the build. Please set
  * the PYTHON_SINGLE_TARGET variable in your make.conf to one
  * of the following values:
  *
  * python2_7 python3_3


but in /etc/portage/make.conf  (there is no /etc/make.conf anymore)
I have


USE_PYTHON="2.7 3.3"
PYTHON_TARGETS="python2_7 python3_3"
PYTHON_SINGLE_TARGET="python3_3"


What am I missing?

Many thanks for a hint,
Helmut.

python3_3 useflags are masked, you probably did not unmask them:

-python_targets_python3_3
-python_single_target_python3_3

in /etc/portage/profile/use.mask

Sorry, I didn't search the web long enough.
It looks like the devs have reintroduced a USE MASK for Python3_3

Here is the old message (2 years old) which is in effect again:
https://forums.gentoo.org/viewtopic-p-6596639.html?sid=bf9c099c72029cd3b9c1dd7efd3a2635

How can I find out what has been changed during a profile update?

Helmut.

Thanks, that must have been reintroduced during a recent profile update.
