Bug 470922 – app-text/asciidoc-8.6.8-r1 - 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_5 python2_6 python2_7 pypy1_9 pypy2_0

• Status: RESOLVED CANTFIX
• Product: Gentoo Linux

[Description Dmitry Isaenko 2013-05-21 22:59:13 UTC]

app-text/asciidoc-8.6.8-r1 failed to emerge because of PYTHON_SINGLE_TARGET collision.
System settings of PYTHON are:
USE_PYTHON="2.7 3.2"
PYTHON_TARGETS="python2_7 python3_2"
PYTHON_SINGLE_TARGET="python3_2"

More info about failure and make.conf + emerge --info below.

This isn't a bug; the error message explains the configuration problem. We set PYTHON_SINGLE_TARGET=python2_7 in the default profile for a reason.

Not all python packages are ready for python3. You can override this using package.env or package.use.

That's explains everything. I didn't know that python2_7 - default for profile, so - my fault. Thank you for your time and explanation, I appreciate that.

[Comment 3 Mike Gilbert 2013-05-22 02:36:04 UTC]

So... why did you just reopen this bug?

If you have reason I'm willing to hear it, but I genuinely believe that this cannot be "fixed" without a major change to the python-single-r1 eclass.
