merging python 2.4.6 in the 2.4 slot fails with the message:

emerge --info

[Comment 2 Justin Lecher (RETIRED) 2009-05-29 08:55:12 UTC]

Does it work with MAKEOPTS=""?
And please use -O2 instead of -Os for testing.

[Comment 3 Robin Johnson 2009-05-29 20:18:39 UTC]

python: maybe parallel build issue?

[Comment 4 zvasylvv 2009-12-11 21:02:10 UTC]

Got same when tried to update from 2.6.2-r1 to 2.6.4

MAKEOPTS='-j5', Intel(R) Core(TM)2 CPU T5600 @ 1.83GHz

Yes, all is OK with '-j1'

[Comment 6 Samu Voutilainen 2010-08-07 13:05:20 UTC]

This happens with 2.6.5(-r2 to -r3 upgrade) too... -j6, with Paludis. I suppose it is caused randomly by paraller compilation.

Solved by -j1.

[Comment 7 Brian Harring (RETIRED) 2010-08-07 13:56:11 UTC]

Post the build log please...

Output of the build

There you go.

[Comment 9 Brian Harring (RETIRED) 2010-08-07 14:47:43 UTC]

ctypes module also isn't parallelization safe (just nailed that on first run with a make -j100... and no, my hardware isn't that good, just a good way to piss off parallelization issues).

I'd really rather not see this get -j1'd... anyone feel like building up some patches?

_ctypes module is built by distutils and distutils doesn't support parallel building/installation.

This bug will be fixed in 2.7.2, 3.1.4 and 3.2.

[Comment 14 Balint SZENTE 2011-06-25 14:39:28 UTC]

I encountered this issue with -j6 on an Intel Core i7 2630QM, but an
# emerge --resume
immediately after the build error compiled the package correctly. Perhaps the error manifests randomly, depending on the compilation scheduling.

[Comment 15 Dirkjan Ochtman (RETIRED) 2011-06-27 09:26:01 UTC]

2.7.2, 3.1.4 and 3.2 are now in the tree, this issue should be fixed (thanks Arfrever).
