perl build log

Fails on arm (imx6q and tegra) with gcc-4.9.3, both linkers, and pretty much any combination of normal/safe/sane flags.

Portage 2.2.27 (python 2.7.11-final-0, default/linux/arm/13.0/armv7a/desktop, gcc-4.9.3, glibc-2.22-r1, 4.4.0-armv7-x3.1 armv7l)

Comment 1 Vladimir Smirnov (RETIRED) gentoo-dev 2016-02-24 08:36:51 UTC
I can't reproduce this. I've tried to build perl with the same use flags you've got and with gcc 4.9.3, but it's still ok for me.

Are you sure that it's not related to distcc somehow?
Comment 2 Vladimir Smirnov (RETIRED) gentoo-dev 2016-02-24 15:43:53 UTC
I've also talked to zlogene, he said that dev-lang/perl is known to have problems with distcc. So please test that you have the same problem with distcc disabled.

I left a message on the #p5p channel (irc.perl.org) and got some feedback. 

1) We found what *triggers* the problem:
"memcpy() NOT found."

Do you know anything whether memcpy really does not exist in that case or whether the detection is somehow returning a bogus result?

[The replacement that is #defined when memcpy is not found is broken, so far noone noticed since "everyone" has memcpy.]

2) I'll add some code to the perl ebuild that outputs additional debug info, and ask you to re-run the log. Not yet, though.

Comment 6 Steve Arnold archtester gentoo-dev 2016-04-27 21:52:49 UTC
I have no idea *why* it fails (other than being broken) but the mis-detected functions are definitely there.  Perl configure just fails at finding them, regardless of features/flags.  It also fails somewhat differently on armv7 vs amrv8 (but the profiles aren't optimized for the latter quite yet).  So let's just say perl sucks at arm.  I'll test it on mips when I get a round tuit but right now my plate isn't nearly big enough...
Comment 7 Steve Arnold archtester gentoo-dev 2016-05-09 02:40:03 UTC
Apparently my udoo board picked up the perl upgrade and the "test" failed (now with a different error).  Hang on and I'll attach a build/config log...
Comment 8 Steve Arnold archtester gentoo-dev 2016-05-09 02:58:00 UTC
Just reopen this one:

Comment 9 Steve Arnold archtester gentoo-dev 2016-05-09 05:01:12 UTC
Nope, same configure bug as before; both -flto and -fwhole-program make it look like ^^ that bug.
Comment 10 Steve Arnold archtester gentoo-dev 2016-06-13 04:53:49 UTC
Seems to be "fixed" so far in 5.24 (no local patches, just plain cflags.conf in the env).

Excellent. Closing since 5.24 is now stable on arm.
