[Description david 2010-11-02 11:02:32 UTC]

Hi everybody, since almost three weeks i've been experienceing multiple problems with my gentoo box. trying to update the world i receive multiple fatal compile errors.
when i try to emerge sys-libs/glibc-2.11.2(-r2) i receive following error:
-------------------
checking for stdint.h... yes
checking for unistd.h... yes
checking size of long double... 0

checking for forced unwind support... no
configure: error: forced unwind support is required
 * ERROR: sys-libs/glibc-2.11.2 failed:

-------------------

furthermore, if i try to emerge sys-devel/gcc-4.4.3-r2 or sys-devel/gcc-4.4.4-r2 i receive following error:

Do you have LDFLAGS="-Wl,-O1 ${LDFLAGS}" in your /etc/make.conf? If you have, does changing that to LDFLAGS="-W1,-O1, ${LDFLAGS} fix this for you?

LDFLAGS="-W1,-O1,${LDFLAGS}" that is.

That appears to be entirely unrelated, if relevant at all. The emerge --info output looks fine in that respect.

@david: Please attach a complete build log for the failed glibc build, as well as the config.log for the failed configure run.

The gcc issue may or may not be related, but should get its own bug report. If they /are/ related, then you have somehow messed up the build environment since the gcc build seems to think it's building an i386 target:

/usr/x86_64-pc-linux-gnu/bin/ld: i386:x86-64 architecture of input file
`/usr/lib/crti.o' is incompatible with i386 output

so maybe you changed CHOST (or CTARGET) without following [1].

First of all: Thanks for your answers, I'm actually really stuck here ;)

1) I tried chaning LDFLAGS without success, it produces the same error.

2) I didn't change CHOST (or CTARGET, didn't know it existed)

I'm afraid gcc not compiling is a result of glibc not compiling and it actually has someting to do with the 32bit compatibility on my amd64 machine. But never changed any configration, here was no need, it always worked perfectly fine.

Hope you guys have an idea on that one.

Also, attach your "environment" file inside ${PORTAGE_BUILDDIR}/temp . You've broken your toolchain/environment or something. Also paste your "gcc-config -l" output.

I assign this to @toolchain, but in your case, I would consider starting a fresh gentoo isntallation. 

[Comment 8 SpanKY 2010-11-19 07:36:14 UTC]

looks like your multilib is broken.  were you using a no-multilib profile at some point ?

does a simple test like this work:
echo 'main(){}' > test.c
gcc test.c -m32
./a.out

gcc-config -l output:

As far as I can remeber i never used the no-multilib profile.

when i try to compile 32bit code following error occurs:

[Comment 11 SpanKY 2010-11-19 08:58:56 UTC]

so yes, your glibc is screwed up.  run this (after emerging portage-utils):
qlist -vv -e sys-libs/glibc > log
qcheck -vv -e sys-libs/glibc >> log

then post the "log" file as an attachment

glibc looks fine.  what does this show:

hi, seems like even the gentoo-developers don't have an idea what reason my errors could have. So i would like to know, whether somebody could give me a hint how i proceed now with minimal system change or "data/config loss", eg. NOT "just extract stage3 again" to get my gentoo working again.

Thanks, and i wish you a happy new year !

verify you have /usr/lib and /lib as symlinks pointing to lib64, and lib32 is a standard directory.  and you dont have any dumb symlinks like /usr pointing to /mnt/backup/usr.

precompiled packages can be found by googling for "gentoo tinderbox" which you can use to recover your system.

spanKY, you won't believe what - thanks to you - just has happened.
as i was checking if i had any lib-symlinks i found that /usr/lib64 was indeed a symlink to /var/lib64 - i originally moved this because of harddisk space-problems. so after i moved /var/lib64 back to /usr/lib64 EVERYTHING compiled successfully.

I'm thankful, that i finally solved this issue with help !

Wish you all a happy new year 2011 !
