[gentoo-user] Troubles setting USE flag for inkscape

[gentoo-user] Troubles setting USE flag for inkscape

[tuxic]

Hi,

while updateing/emergeing I got this message:

##  !!! Problem resolving dependencies for media-gfx/inkscape from @selected 
##  
##  !!! The ebuild selected to satisfy "media-gfx/inkscape" has unmet requirements.
##  - media-gfx/inkscape-1.0_rc1::gentoo USE="jpeg nls openmp -cdr -dbus -dia -exif -graphicsmagick -imagemagick -inkjar -jemalloc -lcms -postscript -spell -static-libs -svg2 -visio -wpg" PYTHON_SINGLE_TARGET="python3_6 python3_8 -python3_7"
##  
##    The following REQUIRED_USE flag constraints are unsatisfied:
##      exactly-one-of ( python_single_target_python3_6 python_single_target_python3_7 python_single_target_python3_8 )


Beside other permutations I add this to package.use

    media-gfx/inkscape python_single_target_python3_8

but the message remains.
As far as I know the above is compatible what is written here:
https://wiki.gentoo.org/wiki//etc/portage/package.use


How do I have to specify the python target correctly?

Cheers!
Meino

"Single target" means you've gotta pick just one.

eselect python update/cleanup options should help you move along with this 
package without having to set up a specific single python target for it.  Let 
it inherit the system version.

Try this instead:

media-gfx/inkscape PYTHON_SINGLE_TARGET: -* python3_8

Hi Remy,

that helped !

To be honest ... I never had deduced this from the error message.
Is this pure experience...somehing one had to learn after uears
of trying to cope with The Portage Oracle...or is it one has
and the other one has not...? ;)

...or what manual do I need to read to up with this line?

(NO critism towards you implied!!!)

Cheers!

For the "Oracle" output of portage:
  ##    The following REQUIRED_USE flag constraints are unsatisfied:
  ##    exactly-one-of ( python_single_target_python3_6 python_single_target_python3_7 python_single_target_python3_8 )
        ^^^^^^^^^^^^^^

So "exactly one of the listed use flags".

For the documentation on syntax:
"man portage" and go to the "package.use" section
or visit
https://wiki.gentoo.org/wiki//etc/portage/package.use

He's just masking all Python single targets (-* = disable all)  except  for  one
(python3_8), thus satisfying the requirement that only one is set.

is fixed now and should work out of the box again

I had similiar problems afterwards with
