[how to permanently USE-flag for one package]

Thank you for the replies!

The way from cardinal worked well.

The way from j-g- doesn't, but it would be quite nice if the solution would be that easy.

[how to permanently USE-flag for one package]

Hi forum,

 

recently I tried

emerge -aDNuv --with-bdeps=y @world

but got only

!!! The ebuild selected to satisfy "media-libs/lensfun" has unmet requirements.
- media-libs/lensfun-0.3.2::gentoo USE="-doc -test" CPU_FLAGS_X86="sse sse2" PYTHON_SINGLE_TARGET="python3_3 python3_4 -python3_5" PYTHON_TARGETS="python3_3 -python3_4 -python3_5"

  The following REQUIRED_USE flag constraints are unsatisfied:
    exactly-one-of ( python_single_target_python3_3 python_single_target_python3_4 python_single_target_python3_5 ) python_single_target_python3_4? ( python_targets_python3_4 )

So I do

PYTHON_SINGLE_TARGET="python3_3" emerge -av lensfun

that worked!

 

But if I try now

emerge -aDNuv --with-bdeps=y @world

it's the same problem.

 

How can I declare only for the lensfun package the PYTHON_SINGLE_TARGET permanently?

 

Merry xmas to all.

 

[Why does updates bring much new packages?]

With todays update, asciidoc updated without the whole texlive stuff.

 

Since I use btrfs I also need the documentation. But there are much more packages that need asciidoc for documentation, i.e. the X-server and some x-libraries and git.

HI j-g-,

 

no I haven't enabled test.anywhere. The output from the emerge tells:

 

[ebuild     U  ] app-text/asciidoc-8.6.9-r2::gentoo [8.6.9-r1::gentoo] USE="-examples -graphviz -highlight {-test} -vim-syntax" PYTHON_SINGLE_TARGET="python2_7 -pypy" PYTHON_TARGETS="python2_7 -pypy" 0 KiB

 

And regarding ruby: I don't like applications that bring much versions of the 'same' thing. On my box a emerge -pv --depclean tells:

 

dev-lang/ruby
    selected: 1.9.3_p551-r1
   protected: none
     omitted: 2.0.0_p647-r1 2.1.7 2.2.3-r1

 

If it was only the last one (2.2.3-r1) i don't complain about it.

Thank you for your reply.

 

And to edit my first entry: it was wxGTK that needs in the new version 3.0 not only some ruby related stuff, it brings also webkit as a dependency.

If it was not for this particular one package I can live good without this.

 

I will look for a solution of this in the Gentoo forums.

[Why does updates bring much new packages?]

Some time ago I was not amused to see that the update to ncurses 6 brings ruby to my box. Why is this necessary?

 

Now I have a new issue like this: the update of asciidoc needs a full texlive! Why?

My box runs well without these packages. But should I mask the updates to hold my system small? Or is there another way?

 

Thank you for some hints or solutions.
