[solved] Howto adjust PYTHON_SINGLE_TARGET per-package

[DeIM]

I've problem while upgrade world with new installed asciidoc:

Code: Select all

!!! The ebuild selected to satisfy "asciidoc" has unmet requirements.
- app-text/asciidoc-8.6.9-r1::gentoo USE="-examples -graphviz -highlight -test -vim-syntax" ABI_X86="64" PYTHON_SINGLE_TARGET="-pypy -python2_7" PYTHON_TARGETS="python2_7 -pypy"

  The following REQUIRED_USE flag constraints are unsatisfied:
    exactly-one-of ( python_single_target_pypy python_single_target_python2_7 )

  The above constraints are a subset of the following complete expression:
    exactly-one-of ( python_single_target_pypy python_single_target_python2_7 ) python_single_target_pypy? ( python_targets_pypy ) python_single_target_python2_7? ( python_targets_python2_7 )

Since I've set PYTHON_SINGLE_TARGET="python3_4", it can't proceed
In https://wiki.gentoo.org/wiki/Project:Py ... ON_TARGETS is that PYTHON_SINGLE_TARGET can be set per-package, but I didn't find how. Thanks for help.

To just add the value python2_7, use

app-text/asciidoc PYTHON_SINGLE_TARGET: python2_7

which is just another syntax for

app-text/asciidoc python_single_target_python2_7

However, if you want to replace the old value, use

app-text/asciidoc PYTHON_SINGLE_TARGET: -* python2_7

In your particular case, all is the same, because python_single_target_python3_4 is ignored by the ebuild. However, for packages which support both, the situation might be different.

Thank you for the nice little tutorial on the REQUIRED_USE syntax. It did the trick with installing asciidoc!
