Bug 498356 – app-admin/eselect-python: python-wrapper ignores EPREFIX

• Status: RESOLVED FIXED
• Product: Gentoo/Alt

[Description Justin Lecher (RETIRED) 2014-01-17 14:06:31 UTC]

"eselect python show" says "python2.7" but python -V says 3.3.3.

 $ type python
python is EPREFIX/usr/bin/python


 $ eix eselect-python
[I] app-admin/eselect-python
     Available versions:  20111108 20131210

     Description:         Eselect module for management of multiple Python versions

 $ eix -e python

$ eselect python list
Available Python interpreters:

 $ eselect python show

$ ll /opt/scisoft64/usr/bin/python
lrwxrwxrwx 1 scisoft scisoft 14 Jan 17 14:58 /opt/scisoft64/usr/bin/python -> python-wrapper


 $ strace -e open python -V

...

open("/etc/ld.so.cache", O_RDONLY|O_CLOEXEC) = 3
open("/lib64/libc.so.6", O_RDONLY|O_CLOEXEC) = 3
open("/etc/env.d/python/config", O_RDONLY) = -1 ENOENT (No such file or directory)

...


Seems to be an error there.

Simply fixing the hardcoded path to the config file solves this problem.

[Comment 2 Fabian Groffen 2014-01-17 16:05:07 UTC]

oh oh, feels like the code doesn't take the prefix into account

[Comment 3 Mike Gilbert 2014-01-19 08:35:39 UTC]

This should fix it. Please test, and if successful I will cut another release.

[Comment 4 Fabian Groffen 2014-01-19 09:19:15 UTC]

that should do, I just have to investigate if we need to do something about the hardcoded fall-back PATH.

[Comment 5 Fabian Groffen 2014-01-24 19:47:51 UTC]

Ok, tested, seems to work ok.  Please release.
