Bug 397815 – net-p2p/deluge-1.3.3 breakage: net-libs/rb_libtorrent-0.15.9 requires the python2 interpreter, but depends on dev-libs/boost-1.47.0-r1 which can be compiled with the python3 interpreter.

• Status: RESOLVED DUPLICATE of bug 382711
• Product: Gentoo Linux

[Description Martijn Schmidt 2012-01-05 23:51:51 UTC]

Compiling net-p2p/deluge-1.3.3 with dev-lang/python-3.2.2 set as main Python
interpreter results in a deluge-gtk crash at runtime. The UI briefly pops up,
but crashes after just moments.

martijn@martijnlaptop ~ $ deluge-gtk 
/usr/bin/python2.7: symbol lookup error:
/usr/lib64/python2.7/site-packages/libtorrent.so: undefined symbol:
_ZN5boost6python6detail11init_moduleEPKcPFvvE

This crash can be avoided by setting the classic_mode flag to false in
~/.config/deluge/gtkui.conf - I have provided a sample config in the attachments
for your convenience. I can then connect to a remote daemon and the rest of the
application works as normal.

Which leads me to believe that the crash is caused by
net-libs/rb_libtorrent-0.15.9 depending on dev-libs/boost-1.47.0-r1, as the
error message indicates.

Deluge depends on rb_libtorrent, and they both require python2. Rb_libtorrent
depends on boost, which accepts both versions of python - in my case I have
chosen python3. Mixing these is apparently a bad idea.

Could this be solved in an elegant way, or is this an issue that needs to be reported upstream to the rb_libtorrent dev team?

Reproducible: Always

Steps to Reproduce:
1. Use eselect to set your main python interpreter to 3.x

2. emerge =dev-libs/boost =net-libs/rb_torrent =net-p2p/deluge

3. Remove ~/.config/deluge/gtkui.conf in case you've had Deluge installed previously.

4. deluge-gtk from the console so you can view stdout

5. Notice crash due to rb_libtorrent depending on boost.

6. Set the classic_mode flag to false in ~/.config/deluge/gtkui.conf

7. deluge-gtk starts and works properly now, as long as you don't try to start a local daemon.
Actual Results:  
Can't run a deluge daemon locally.

Expected Results:  
Deluge daemon runs as normal, OR it's made clear at buildtime that rb_libtorrent doesn't work with boost linked to python3.

Quick clarification, the crash of rb_libtorrent can't be avoided, but you do circumvent it this way because rb_libtorrent is never called in thin client mode.
