[SOLVED] live-build i domyślny python w systemie

Chciałem sobie zbudować nieco bardziej aktualny obraz live na pena ale dostałem taki komunikat:

Kod:

# lb build
[2013-10-20 22:53:29] lb build 
P: Executing auto/build script.

Jestem podpięty pod ten śmieszny system mailingowy debiana live i tam był podobny przypadek. Z tym, że koleś napisał:

The Python code "print('E: config/build - no such file', file=sys.stderr)"
works fine for me in python 3.3.2, but the default python on my system is
2.7.5, and it doesn't work there.[/quote]
Cały bug tutaj: http://lists.debian.org/debian-live/2013/10/msg00051.html

Mam obecnie zainstalowane dwa pythony — 2.7 i 3.3.

W /usr/bin mam:

Kod:

# ls -al /usr/bin/python*
lrwxrwxrwx 1 root root    9 Oct 20 22:33 /usr/bin/python -> python2.7*
lrwxrwxrwx 1 root root    9 Sep 13 23:40 /usr/bin/python2 -> python2.7*
-rwxr-xr-x 1 root root 3.1M Sep 17 21:32 /usr/bin/python2.7*
lrwxrwxrwx 1 root root    9 Sep 23 21:44 /usr/bin/python3 -> python3.3*
-rwxr-xr-x 2 root root 3.6M Sep 23 23:53 /usr/bin/python3.3*
-rwxr-xr-x 2 root root 3.6M Sep 23 23:53 /usr/bin/python3.3m*
lrwxrwxrwx 1 root root   10 Sep 23 21:44 /usr/bin/python3m -> python3.3m*

Zgodnie z tym co piszą na wiki archa: https://wiki.archlinux.org/index.php/python — miałem poczynić poniższe kroki by domyślnym pythonem w systemie był ten 3.3 zamiast 2.7:

Kod:

# cd /root
root:~# mkdir bin
root:~# ln -s /usr/bin/python3.3 ~/bin/python
root:~# tree /root/bin/
/root/bin/
└── python3.3 -> /usr/bin/python3.3

0 directories, 1 file
root:~# export PATH=~/bin:$PATH
root:~# echo $PATH
/root/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

Myślałem, że to załatwi sprawę ale podczas próby zbudowania obrazu, dostałem znowu ten sam komunikat. Patrzę dalej na wiki archa i tam jest:

To check which python interpreter is being used by env, use the following command:

$ which python[/quote]
No to wpisałem mu powyższe polecenie:

Kod:

# which python
/usr/bin/python

Czyli nie używa tego linku w /root/bin.

Na wiki archa był jeszcze python2-config ale tutaj u mnie nie ma żadnego python + config w /usr/bin/ .

Jako, że w /usr/bin/ python jest podlinkowany pod 2.7 , to usunąłem to dowiązanie i i podlinkowałem go bezpośrednio do 3.3:

Kod:

# cd /usr/bin/
root:/usr/bin# rm python
root:/usr/bin# ln -s python3.3 python
root:/usr/bin# ls -al python*
lrwxrwxrwx 1 root root    9 Oct 20 23:09 python -> python3.3*
lrwxrwxrwx 1 root root    9 Sep 13 23:40 python2 -> python2.7*
-rwxr-xr-x 1 root root 3.1M Sep 17 21:32 python2.7*
lrwxrwxrwx 1 root root    9 Sep 23 21:44 python3 -> python3.3*
-rwxr-xr-x 2 root root 3.6M Sep 23 23:53 python3.3*
-rwxr-xr-x 2 root root 3.6M Sep 23 23:53 python3.3m*
lrwxrwxrwx 1 root root   10 Sep 23 21:44 python3m -> python3.3m*

Ale to też nie pomaga, z tym, że teraz dostaje nieco inny błąd przy budowaniu obrazu:

Kod:

# lb build

Wersja live-build jest z experimentala bo z tą z testinga były jakieś problemy.

Kod:

# dpkg -l | grep live-build
ii  live-build                                                  4.0~alpha27-1                       all          Live System Build Components

Ostatni obraz budowałem jakiś czas temu i wszystko było w porządku ale to dziwne, że tej osobie z listy mailingowej się buduje na pythonie 3.3, a u mnie nie chce. xD Jakieś pomysły?

Re: [SOLVED] live-build i domyślny python w systemie

Wygląda na to, że problem został poprawiony w  live-build v. 4.0~alpha29-1 :

Kod:

Changes: 
 live-build (4.0~alpha29-1) experimental; urgency=low
 .
   * Updating to standards version 3.9.5.
   * Rewriting bootstrap_hooks in python.
   * Making various things in bootstrap manpages more consistent.
   * Also processing config/hooks/*.hook in bootstrap_hooks, if any.
   * Adding lb_bootstrap_hooks manpage.
   * Rewriting chroot_hooks in python.
   * Adding lb_chroot_hooks manpage.
   * Updating file suffixes of the internal default hooks.
   * Automatically symlink hooks upon creation of the configuration tree.
   * Updating configuration path in update-apt-file-cache.hook.chroot.
   * Rewriting binary_hooks in python.
   * Adding lb_binary_hooks manpage.
   * Rewriting source_hooks in python.
   * Adding lb_source_hooks manpage.
   * Adding see also entries in hooks manpages.
   * Moving python stubs to their own subdirectory within the source tree.
   * Manually adding --version to argparse in python stub since python 3.3
     dropped the version keyword.
   * Replacing os.link calls for hooks with shutil.copy to properly
     dereference symlinks in python stubs.
