Bug 413869 – sys-libs/glibc-2.15 / MIPS: build failure plus fix

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description Manuel Lauss 2012-04-28 12:58:50 UTC]

glibc-2.15[-r1] fails to build on MIPS and to cross-build for MIPS in the install phase.
The good folks at timesys have a patch which fixes the build both in cross and native environments.

http://repository.timesys.com/buildsources/g/glibc/glibc-2.15/glibc-2.15-mips-syscall-list-abi.patch

Please include it in the glibc-2.15 patch archive.

Reproducible: Always

no actual details as to what is failing.  this change isn't in upstream glibc, so i'm not inclined to pick it up until we have real details.

[Comment 2 Manuel Lauss 2012-05-02 05:04:49 UTC]

Right, sorry about that:

Install phase, near the end.  (Bugzilla won't let me upload the compressed
build log).

here's the full build log.

[Comment 4 SpanKY 2012-08-12 03:40:48 UTC]

why doesn't your gcc support -march=mips32 ?  my gcc supports it just fine.

[Comment 5 Manuel Lauss 2012-08-12 04:37:57 UTC]

it does support mips32.  But the whole thing is moot now; I've upgraded to 2.16 when it hit portage.
