bug#21879: WeeChat does not start

[Luis Felipe López Acevedo]

Hi,

I installed WeeChat 1.3 using Guix 0.9.0 on Debian 8, but It doesn't
start when I run it. I get this error instead:

Seems like you are using weechat from Guix using Python 2.7 from Debian,
which is a bit weird. Also, _sysconfigdata_nd is Debian-specific. What
is your PYTHONPATH?

On closer inspection, this comes from the fact that Weechat looks for a
‘python’ executable in $PATH.  See src/plugins/python/weechat-python.c
in Weechat.

In your case, it ended up running Debian’s Python, which then failed for
reasons that are unclear to me.

I believe this is fixed by a9346fa and 7be4a4b.  Could you confirm?
You could run ‘guix pull’ or pull from a current ‘master’ checkout.

Thanks,
Ludo’.

In a different machine, but still Debian 8 and Guix 0.9.0:

1. I ran 'guix pull'
2. Installed weechat

I get the same error.

On Debian Sid + Guix, I installed weechat in a "guix environment", and
could not reproduce the issue (weechat properly starts). However,
running "PATH=/usr/bin:$PATH weechat" leads to the same error you witnessed.

Could you post you PATH and PYTHONPATH?

Cyril.

Could you double-check what’s happening, possibly running it through
strace to see if it’s actually executing /usr/bin/python?

Maybe my attempt was misguided and the problem is actually not in the
Python plugin but in some core part?

Thanks,

I'm pretty sure it does that. It even loads libraries from the Debian
Python path, that is why it tries to import a Debian-specific module.

Weird.  Could you check with strace and/or GDB to confirm and see where
it’s coming from?

When I run it through strace, I don’t see any attempt to exec python.

TIA.  :-)

I tried this:

  guix environment --container --ad-hoc weechat strace coreutils \
     findutils sed grep less --expose=$(which false)=/usr/bin/python

which installs ‘false’ as /usr/bin/python, but it still works fine.

Felipe, could you report the values of the ‘PYTHONPATH’, ‘PATH’, and
‘LD_LIBRARY_PATH’ variables on your system?

Are you able to work around the problem with:

  guix environment --ad-hoc weechat --pure -- weechat

?

TIA,
Ludo’.

Oh, I didn't get Cyril's messages on the bug... But this is the 
information:

PYTHONPATH and LD_LIBRARY_PATH are empty. PATH has this value:

/home/anonimo/.guix-profile/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games

Additional info:

$ guix package --search-paths
export PATH="/home/anonimo/.guix-profile/bin"

WeeChat starts correctly if I run it that way.

What if you do:

  guix package -i python-2
  weechat

?

Hmm, hmm!  In commit cb7bd0c, I fixed a build issue with the Python
plugin (it was statically linking libpython.a, which is undesirable.)

Could you check if that makes a difference, removing Python from your
profile?

Thanks for your help!

- Removed Python and WeeChat from my profile.
- Did guix pull.
- Reinstalled WeeChat.

The error persists.

I noticed this as well on a foreign distro and pushed a workaround in
507809be152049dff26bffdb58e1a90b638f046b.

Didn't study the source enough to figure out why the substitution was
insufficient, but strace confirmed it was still looking in PATH even
though the strings were replaced.

The commit that worked around the issue was applied after the 0.12.0
release. Have you updated your copy of Guix (with `guix pull`) since the
0.12.0 release?

Thanks, Leo. I installed WeeChat after "guix pull" and it worked.

A while ago Leo or someone else uponed a bug on improving the
Documentation about the relevance and usage of package+system updates.

It seems to me as if that's the case here, the documentation not being
clear enough.
Do you have any improvement suggestions?

Good! Documentation is one part. I'll read the bug you mention (https://debbugs.gnu.org/cgi/bugreport.cgi?bug=25852) and see if I have anything to contribute.

Thank you, ng0.
