I've been bumping into failures installing Matplotlib 1.2.0-r2: |
| 2 |
|
| 3 |
# cat /tmp/livecd-stage1.log |
| 4 |
… |
| 5 |
/build/lib/matplotlib/tests/baseline_images/test_delaunay |
| 6 |
Traceback (most recent call last): |
| 7 |
File "/usr/lib/python3.2/multiprocessing/synchronize.py", line 54, in <module> |
| 8 |
from _multiprocessing import SemLock |
| 9 |
ImportError: cannot import name SemLock |
| 10 |
… |
| 11 |
ImportError: This platform lacks a functioning sem_open implementation, |
| 12 |
therefore, the required synchronization primitives needed will not function, |
| 13 |
see issue 3770. |
| 14 |
… |
| 15 |
|
| 16 |
Looking through my logs, it seems that some versions of Python 3.2.3 |
| 17 |
found a sem_open implementation, but some did not: |
| 18 |
|
| 19 |
$ cd /var/log/catalyst |
| 20 |
$ grep sem_open dev-lang\:python-3.2.3\:* |
| 21 |
dev-lang:python-3.2.3:20130310-213508.log:checking for sem_open... yes |
| 22 |
dev-lang:python-3.2.3:20130310-222606.log:checking for sem_open... no |
| 23 |
dev-lang:python-3.2.3:20130310-234410.log:checking for sem_open... yes |
| 24 |
|
| 25 |
I cleaned out my logs before my last run, so we can match those build |
| 26 |
times up with stages: |
| 27 |
|
| 28 |
$ grep dev-lang/python-3.2.3 /tmp/*.log |
| 29 |
/tmp/stage1.log:>>> Emerging (14 of 17) dev-lang/python-3.2.3 |
| 30 |
/tmp/stage1.log:>>> Installing (14 of 17) dev-lang/python-3.2.3 |
| 31 |
/tmp/stage1.log:>>> Emerging (72 of 75) dev-lang/python-3.2.3 for /tmp/stage1root/ |
| 32 |
/tmp/stage1.log:>>> Installing (72 of 75) dev-lang/python-3.2.3 to /tmp/stage1root/ |
| 33 |
/tmp/stage3.log:>>> Emerging (99 of 189) dev-lang/python-3.2.3 |
| 34 |
/tmp/stage3.log:>>> Installing (99 of 189) dev-lang/python-3.2.3 |
| 35 |
|
| 36 |
So the stage1 seed_update emerge finds sem_open, but the stage1root |
| 37 |
setup does not. I'm not sure why this would happen, but since the |
| 38 |
stage3 emerge *does* find sem_open, I'm not sure why the Matplotlib |
| 39 |
emerge is failing in livecd-stage1. Does anyone want to take a guess? |
| 40 |

Thanks, |
