Every run of emerge makes system segfaulting

[Jinidog]

Cheers,

the whole mess started when I tried to update to glibc 2.7.

The compile went fine but when portage copied the glibc-files into the filesystem, it stopped somewhere in the process with a segfault.
After that the system was not useable anymore. Simple console commands resulted in segfaults.
When booting the system now segfaults just when the kernel calls init.

I repaired the damage by building a glibc-2.6 package somewhere else and copying all its files into the filesystem. After that everything works again.

Well, I tried to merge glibc-2.7, 2.8 and 2.6.1 again. Every time the systems was unuseable after merging the files into the filesystem.
EVEN when I want portage to install the glibc package that I use to rescue my system (by copying its content to / ) I only get segfaults.
Every run of emerge does it. For example I run "emerge dialog" and after that my whole system segfaults and works again when I copy the working glibc-files by hand.

What is going on here?

Can you post your "emerge --info" ?

[Jinidog]

Posted above. Changed the problem description and the title. It is not only a problem with glibc anymore. Every run of emerge makes my system segfaulting. Even when I compile such small and unimportant things like dialog.

Portage 2.1.4.4 (default-linux/amd64/2007.0, gcc-4.2.4, glibc-2.7-r2,glibc-2.6.1-r0, 2.6.24-gentoo-r8 x86_64)

As far as I know, sys-libs/glibc is not a slotted package, so something is really broken if you have 2 different versions installed at the same time.


ps. Are you trying to upgrade your whole system to ~ARCH ?

[Jinidog]

Well, the problem started when portage tried to merge the first glibc 2.7 package.
During this operation the system got unuseable and it didn't complete.
So it left me with a half installed glibc 2.7.

Every operation to unmerge glibc 2.7 or 2.6 can not complete because it segfaults.

Well, I'm currently building a fresh gentoo install. Don't believe I can repair this.

are you sure it's no hardware problem?
it could be memory modules or motherboard issues.

Have you tried with sane CFLAGS? Something like "-O2 -march=native -pipe" should do. You can switch -march to "native" because you're using >=GCC4.2. That will automatically determine the best -march= option based on the processor info. That also includes the -msse3 switch. Also "-fomit-frame-pointer" isn't needed on AMD64 architecture because GCC enables it with -O2 on AMD64. If you want to compile glibc with "-fomit-frame-pointer" you can use the local package USE "glibc-omitfp". The other flags are known to be unstable in some cases, especially "-mfpmath".
If I'm right glibc should filter out unstable CFLAGS by default, but you may give it a try anyway.

[Jinidog]

Well, well.
But as I wrote. I could even do a
"emerge dialog" or "emerge nbench" and the result is a unuseable system.
My CFLAGS are quite sane, I would say. At least they worked for one year

Hardware problem is not likely. I'm currently building a new gentoo in a chroot and there I have no problem.
