problem with ski & NUE

[Daniele Velardi]

Hi,
i have already read your mailing list, but i don't try
the answers: many thing are take for granted, and they
aren't in any manual, please help me! excuse me for my
english!
-I am a dummies: can i boot kernel mode with file
bootloader e vmlinux find on hp labs site? i type
inside nue and outside nue: 
"ski bootloader vmlinux simscsi=/var/ski-disks/sd"
where the two files bootloader and vmlinux are locate
in the current directory!The resulting error is:
"BFD:Dwarf Error: Invalid or unhandled FORM value: 14.
Segmentation fault"! 
How can use the parameter "root="? 
i must compile a new kernel depending of my hardware
and the kernel version of my system host? 
-why i need to use this option to boot ski with the
binary hello? i need use this also for boot the
kernel? There is some problems? 
-I have installed ski-0.943.rpm and the other rpm and
all work well, but now i have copied the fiel in
ski-0.981.tar in my disk, but ski don't work: 
ski:/usr/i386-glibc21-linux/lib/libpthread.so.0:
version `GLIBC_2.2' not found (required by ski) 
ski:/usr/i386-glibc21-linux/lib/libpthread.so.0:
version `GLIBC_2.3.2' not found (required by ski) 
What is wrong?

That happens when you use an old bfd library to try to read an object
file created by a recent bfd library.  Form 14 is DW_FORM_strp (string
pointer), which is used by recent bfd versions to optimize away
duplicate strings in the debug info.  This helps reduce object file
size.  But older bfd's that lack DW_FORM_strp support will get confused,
and may fail.

So presumably the problem here is that the ski binary you have was
linked against an old bfd version, and the vmlinux binary you have was
created with a recent bfd (binutils) version.  You are probably out of
luck unless you can get a updated ski version.  If ski is perhaps using
a shared library libbfd.so on your system, then updating that library
(or updating the OS) may help.  Try running ldd on the ski binary.

Stripping the debug info from vmlinux may get you past this problem, but
then you won't be able to debug the linux kernel.

This likely means you have an old OS installed on your system, an OS
that came with glibc-2.1, and ski was compiled on a system with a newer
OS that came with glibc-2.2 and/or glibc-2.3.  You probably have to try
a newer OS.  You could maybe install a newer glibc version on your
system, but building glibc isn't easy.  Installing a newer OS is easier.

on my OS is already installed glibc 2.3.2 (suse 9.0)!
don't seem a problem! 
For install the ski version 0.981 form the tar-ball, i
have overwrite the file of directory NUE created form
the last rpm's:
ski 0.943
nue 1.1.1
nue fs 1.2 
My installation procedure is correct?
Then for the system mode, i have tried to boot ski
bootoloader vmlinux, it is correct or i have to
recompilte all for my machine?
The DW_FORM_strp error result with gcc v 2.96 and then
also with gcc3 (form nue-gcc3-010625.tar.gz) and with
the as v2.13 (gas-030124.tar.gz). it 's all ok?

Then I don't know what the problem.

The problem is clearly not that your OS is too old.  Perhaps the problem
is that the OS is too new then, or perhaps that you are using suse and
the ski binary was compiled under Red Hat Linux.  The nue release you
are using is 3 years old, a lot of things have changed since then.

I haven't used ski in a long time, and there are probably not many other
people still using it, so you may have trouble finding more useful help.

You might try running ldd on the ski binary to see what libraries it has
been linked against, and to check if those libraries are present on your
system.

You need compatible bfds in the generator (as/ld) and the reader (ski). 
Since ski is only available as a binary, and a fairly old one, that
implies that you will have to use an old gcc and binutils releases to be
compatible with it.  Using an old as isn't enough, you need both an old
as and ld.

However, this is all speculation.  You may have to spend some time
investigating these problems yourself.

Please don't use nue --- it's very very old.  Ski from the current
download site should work fine, but you'll need to build yourself (or
get hold of somehow) a recent gcc and binutils built as cross
compilers.   The ones in the nue-fs are too old to build today's
kernels.   See http://gelato.unsw.edu.au/IA64wiki/CrossDevelopment for
more information,including how to build cross compilers etc -- use the
AlternateCrossCompilation link as you're using Suse not Debian.  Or
Dan Kegel's cross compilation building method at
http://kegel.com/crosstool/
