New submission from David Coconut <coco...@redbrick.dcu.ie>:
Operating system: Ubuntu 10.04 Lucid Lynx (Beta)
This worked with Python 3.1 on 9.10 Karmic Koala. The same error appears on two
separate installations of Lucid.
Issue 3770 does not seem to be relevant here.
Traceback (most recent call last):
File "/usr/lib/python3.1/multiprocessing/synchronize.py", line 28, in <module>
from _multiprocessing import SemLock
ImportError: cannot import name SemLock
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File
"main.py", line 16, in <module>
q = JoinableQueue()
File "/usr/lib/python3.1/multiprocessing/__init__.py", line 218, in
JoinableQueue
from multiprocessing.queues import JoinableQueue
File "/usr/lib/python3.1/multiprocessing/queues.py", line 22, in <module>
from multiprocessing.synchronize import Lock, BoundedSemaphore, Semaphore,
Condition
File "/usr/lib/python3.1/multiprocessing/synchronize.py", line 33, in <module>
" function, see issue 3770.")
ImportError: This platform lacks a functioning sem_open implementation,
therefore, the required synchronization primitives needed will not function,
see issue 3770.
