The latest version of binutils (2.13.90.0.4) actually won't install my kernel and modules correct. There are a lot of "unresolved symbols" errors when
it comes to depmod. It's definitely not a kernel config issue since compiling and installing works nice with binutils 2.11 . If you know a workaround (best would be fixing kernel sources so they get along with the latest binutils version) then please let me know.

Greetings,

Actually I'm running gentoo 1.4b but that shouldn't matter. ;) The problem is the discrepancy between binutils and kernel sources (in my case gentoo-sources).

I'm having the same problem now. Just built a base 1.4b system, with the kernel failing. It boots and i can insmod the modules in the correct order, but i feel fucked up.

I want cumbrelocks, so i cannot downgrade binutils.

I'm using vanilla-sources 2.4.19 patched with the xfs big patch for it.

Moving from Installing Gentoo to Other Things Gentoo, since it's outside the scope of the initial installation.

If the comment in bug 6730 about ignoring the messages doesn't work for you, the CPU you are using might be of interest to people who could try to help.

binutils-2.12.90.0.7 also have combreloc enabled by default.

Maybe check your config again ... Verwilst and Gerk havent
reported any of these problems. What kernel btw?

I forgot to mention that it indeed works
with binutils-2.12.90.0.7. Other versions
higher than that won't work on my system.
I had the same problem on a Debian system
with binutils-2.12.90.0.15 installed. There it
was an official bug; and there was an "official"
workaround for that. Watch my comments on
BUG #6730 on bugs.gentoo.org. :) Sorry bout
the format of this text, Im writing this
within lynx. ;)

I've made some research and found out
that maybe it isn't a binutils issue but
a conflict of binutils with the current
version of modutils found in the portage tree. Some
people didn't have any problems
building kernels, some (including me) have.
It's possibly an architecture problem.
My system as described below:
Athlon TB 800 Mhz
512 MB Ram
Gentoo 1.4b (with gcc-3.2)

I'm now going to install the old
version of binutils again as this should
work.

same issue here:

fresh Gentoo 1.4 (final?), gentoo-source-2.4.19-r7, binutils 2.13.xxx:

lots of unresolved Symbols with the kernel modules

now trying binutils 2.12.90.0.7 ... will report back later

I had the same problem. I don't know if ignoring it will work for me or not because I'm still compiling the rest of the system. I'll update y'all when I know more.

P3 (mobile) -1000 MHz and binutils 2.13.90.0.4

going back to 2.12.90.0.7 helped here:

no issues with the kernel and building the rest of the system works so far:
X is done, mozilla is done ... working on gnome2 etc ...

You can:

Downgrade binutils: You lose combrelocks and other nice things :(.
Workarround with insmod: Kernel and its modules works perfecly if you load the modules you need in the correct order with insmod. The problem is with modprobe, that will be unable to resolve the dependences between modules, but if you use insmod there's no major pain until a real fix comes.

Because this issue seems to only affect kernel modules and some people do not want to switch back to some older version of binutils a workaround is to just compile everything you need into the kernel -- without modules.

The only module which I load is the NVidia kernel module, which works just fine.

Cheers,
Andreas

Like I already stated, 2.12.90.0.7 do have combreloc
enabled. As a fact, it was enabled by default from 2.12.*,
so as long as you do not downgrade to 2.11.*, you will
be fine.

Ok, here it is: It is indeed a modutils issue.
I made a quick ebuild hack for the
latest version of modutils (2.4.19). Then
kernel building works like a charme.
I will attach this ebuild to BUG #6730 .
For all the impatient: You may download
this file from http://www.databoogie.net/modutils-2.4.19.ebuild to satisfy your
installation needs with Gentoo 1.4 :)

Hi all,

(tried posting this in a new thread since it's not really related to the thread subject, except for the fact that we are talking about modutils, but a mod. locked it. So anyway, here goes:)

i upgraded to 2.13.90.0.4 yesterday morning (after having upgraded to GCC3 and having the system up and running perfectly for about a day), and now I cannot get anything to compile with dynamic linking... not even "Hello, world". Any executables immediately segfault, running an strace on them just shows that they load ld.so, but fail on some sort of mmap syscall.

I've tried downgrading/memerging binutils through setting CFLAGS="-O0 -static", but that fails with the following error message:

Code:

echo $f > tofiles

Line 95 in libbfd.h is

Code:

extern bfd_error_handler_type _bfd_error_handler;


and it seems that the bfd_error_handler_type is not defined. This causes the parse error. Just on a whim i tried to search for the bfd_error_handler in the kernel tree, and sure enough, it's defined in a header called bfd.h in /usr/src/linux somewhere. However the version that's in there seems to be an old leftover from when i used GCC 2.95.X to compile the kernel.

Anyone have any clues as to what's going on and how I can get back to a usable system? (Well, the system is usable, but I can't emerge anything without "-static" which is kind of a bummer...

This seems to be a major problem with updating binutils. If you're only using the version of binutils installed when bootstrapping then you should have no problems. Otherwise you will fail
to compile anything. I hope this is being worked out. So, for the moment it's the best to bootstrap with the latest version of binutils and modutils.

Nevermind. After reworking the binutils ebuild slightly i finally got it to compile, but unfortunately the binaries were completely hosed. Oh,well... off to build a stage2 system and making binary packages...

Well, that was discouraging. I've just tried starting from the stage1-1.4b tarball, doing exactly as described in the install doc:

  1. tar xfj stage1-...
  2. setting CFLAGS, PROXY, etc. in /etc/make.conf
  3. emerge sync
  4. (cd /usr/portage; scripts/bootstrap.sh)

and that also fails, producing binutils which don't work. (Btw, this was done in a chroot, so it is a completely clean environment).

I'll try removing "-fomit-frame-pointer" from the CFLAGS and bootstrap from stage1 again to see if that works better.

Well...what exactly didn't work for you while bootstrapping? binutils seems to compile fine. The ony problems lies within building a kernel with modules (but that's a problem of modutils-2.4.16). :roll:

Like I said, binutils wouldn't work, for example gcc would compile hello_world.c, but the executable would immediately segfault. But I have now isolated the problem. It seems that the new binutils will simply break (NOTE: the b0rked binutils will install, breaking your installation completely) if you use the "-fomit-frame-pointer" flag to the compiler (this was with GCC3.2).

Once I removed that flag, the new binutils seemed to work fine.
I've added this to the current binutils bug on bugs.gentoo.org, so hopefully something will be done to remove the "-fomit-frame-pointer" flag before compilation of binutils in a new revision of the binutils ebuild.

Should be fine if you can get it merged now and your
rsync server is up to date, as Verwilst have already fixed
this on CVS.
