set raw LDFLAGS

[Comment 2 Justin Lecher (RETIRED) 2012-08-24 01:04:08 UTC]

i never had problems with that. Waht is wrong here?

build.log

[Comment 4 Dennis Schridde 2012-08-24 08:34:46 UTC]

It appears that the kernel buildsystem calls ld directly, instead of via GCC:
/usr/src/linux-3.5.2-gentoo/Makefile: LD              = $(CROSS_COMPILE)ld

[Comment 5 Justin Lecher (RETIRED) 2012-08-26 09:38:59 UTC]

Here it doesn't call ld directly. Please attach the build.log with MAKEOPTS="V=1"

[Comment 6 Dennis Schridde 2012-08-27 11:09:45 UTC]

build.log (MAKEOPTS='V=1')

Could you please grep ^LD /usr/src/linux/Makefile? I'd be interested what it calls on your side.

[Comment 8 Justin Lecher (RETIRED) 2012-08-27 11:16:51 UTC]

# grep ^LD /usr/src/linux/Makefile
LD		= $(CROSS_COMPILE)ld
LDFLAGS_MODULE  =
LDFLAGS_BUILD_ID = $(patsubst -Wl$(comma)%,%,\
LDFLAGS_vmlinux += $(LDFLAGS_BUILD_ID)
LDFLAGS_vmlinux	+= $(call ld-option, -X,)

[Comment 9 Justin Lecher (RETIRED) 2012-08-27 11:19:19 UTC]

Oh I was wrong. ld gets called but without LDFLAGS.

[Comment 10 Dennis Schridde 2012-09-13 12:46:35 UTC]

Were you able to reproduce this?

[Comment 11 Justin Lecher (RETIRED) 2012-09-13 14:16:56 UTC]

Not yet. I will fix all the current bugs with the next bump for linux-3.5. I will have no real time for this until 2. week of october.

Was this dropped again? It seems LDFLAGS was dropped from the emake commandline again, and flag-o-matic is no longer inherited.
