pthread_setname_np and musl don't seem to like each other?

Comment 2 Felix Janda 2016-09-07 11:37:28 UTC
musl doesn't have pthread_setname_np. "np" stands for non-portable, and
indeed for different systems the number and type of arguments differs.
To make firefox happy, musl would need to implement the same variant as
glibc or Mac OSX. In

the musl author says that there are no major objections to adding it.

patch for sys-libs/musl
Comment 4 tt_1 2016-09-16 18:56:05 UTC
The patch for musl solves the compile error of firefox. Is it a copy from glibc?
Comment 5 Felix Janda 2016-09-17 01:08:30 UTC
No, the function is written from scratch using the man page. An
improved version of this patch is currently being reviewed on the musl
mailing list.
Comment 6 Nicholas Fish 2016-09-17 15:43:40 UTC
I was also able to build and run www-client/firefox-49.0_beta10 against  musl-1.1.15 with the improved version of Felix's patch from .
Comment 7 Ian Stakenvicius (RETIRED) gentoo-dev 2016-09-21 14:27:07 UTC
So if musl is what needs the patch, is there anything I should do before I commit firefox-49.0 to the tree?
Comment 8 tt_1 2016-10-20 08:30:16 UTC
The patch has been commited upstream at
Comment 9 tt_1 2017-01-13 21:21:35 UTC
this has been fixed in musl-1.1.16
