Description Michael Hofmann 2018-12-23 18:43:17 UTC

emerge =net-misc/ntp-4.2.8_p11 works as expected

emerge =net-misc/ntp-4.2.8_p12 aborts with:

There's already a bug report upstream: http://bugs.ntp.org/show_bug.cgi?id=3539

Developers have a patch: http://bugs.ntp.org/attachment.cgi?id=1628

I tested the patch. I can confirm that the patch solves the problem.

Comment 4 Michael Hofmann 2018-12-24 11:22:43 UTC

This bug seems to occur if ntp is emerged without USE flag 'threads'. I can reproduce the error on non-affected machines with: USE="-threads" emerge ntp.

Or the other way round: another solution would be to emerge ntp WITH use flag 'threads'.
