Bug 426330 – net-irc/weechat-3.7 and net-irc/weechat-3.8 have crippled python3 support

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description M. B. 2012-07-12 15:03:17 UTC]

The python detection mechanism in weechat is broken. This results the following message at startup of weechat:
15:52:40 =!= | Fehler: Kann Erweiterung "/usr/lib64/weechat/plugins/python.so" nicht installieren: /usr/lib64/weechat/plugins/python.so: undefined symbol: PyBytes_AsString

My system-python is set to 3.2 (via eselect); i still have python-2.7 installed.

My reasoning behind stating that their detection mechanism is broken:
ebuild /usr/portage/net-irc/weechat-0.3.8/weechat-0.3.8.ebuild unpack &&
cd /var/tmp/portage/net-irc/weechat-0.3.8/work/weechat-0.3.8 &&
cmake . -LA | grep -i python

gives:
PYTHON_EXECUTABLE:FILEPATH=/usr/bin/python
PYTHON_INCLUDE_PATH:PATH=/usr/include/python3.2
PYTHON_LIBRARY:FILEPATH=/usr/lib64/libpython2.7.so

Quickfix: eselect to python-2, emerge, then eselect back to python3. though probably python-updater will break it again upon next run.

PS: I will file a bug with weechat on savannah as well.

Reproducible: Always

patch proposal for weechat.ebuild

I fixed weechat to compile the python plugin properly against a USE-flag chosen implementation of python.

Reassigning to @python as I myself don't have py3 anywhere and don't want to fck up anything.

Could anyone of you guys look on this and tell me what to do?
Thanks

Update: upstream has fixed build in trunk to default to python2. Still there's no support in weechat's build system to choose for the python version except for my hack.

[Comment 8 Tomáš Chvátal (RETIRED) 2012-08-21 13:26:41 UTC]

Ok I updated live ebuild and 0.3.8 to always pick the python2 until decided otherwise.

Marking as fixed for 4.0 (different fashion with python-single-r1).

Open a new bug if you find some problems with it please.
