[gentoo-devhelp] How does PYTHON_COMPAT work?

[Nikos Chantziaras]

I have an ebuild where:

   PYTHON_COMPAT=( python3_3 python3_4 )
   inherit distutils-r1

works just fine. Now python 3.3 doesn't work anymore for the software, 
so I removed that. But this:

   PYTHON_COMPAT=( python3_4 )
   # or: PYTHON_COMPAT=python3_4
   inherit distutils-r1

doesn't work. During emerge:

Calculating dependencies \

!!! Problem resolving dependencies for net-misc/livestreamer
... done!

!!! The ebuild selected to satisfy "livestreamer" has unmet requirements.
- net-misc/livestreamer-1.9.0::Local USE="" ABI_X86="64" 
PYTHON_TARGETS="-python3_4"

   The following REQUIRED_USE flag constraints are unsatisfied:
     python_targets_python3_4

   The above constraints are a subset of the following complete expression:
     any-of ( python_targets_python3_4 )

Hi,

You have not enable python 3.4 as a python provider in your make.conf.
But for the emerge you need to set at least one python ABI. Just add

net-misc/livestreamer python_targets_python3_4

to your package.use.

I'm not making any progress. I've added:

   USE_PYTHON='3.4'

in my make.conf. I've also done "eselect python set python3.4". I still get:


!!! The ebuild selected to satisfy "livestreamer" has unmet requirements.
- net-misc/livestreamer-1.10.0::Local USE="" ABI_X86="64" 
PYTHON_TARGETS="-python3_4"

   The following REQUIRED_USE flag constraints are unsatisfied:
     python_targets_python3_4

   The above constraints are a subset of the following complete expression:
     any-of ( python_targets_python3_4 )


Doesn't make any sense. So I added:

   net-misc/livestreamer python_targets_python3_4

to my package.use (even though I shouldn't need to, since I've set 
PYTHON_USE). Now the emerge begins, but fails:


  * python3_4: running distutils-r1_run_phase distutils-r1_python_compile
/usr/bin/python3.4 setup.py build
Traceback (most recent call last):
   File "setup.py", line 5, in <module>
     from setuptools import setup
ImportError: No module named 'setuptools'

OK, turns out the ebuild message was lying. USE_PYTHON is useless. I 
need to set these:
