Hi all,
How can we export symbols of a module in linux 2.4 ?
I know that in later versions of linux, we use the register_symtab
fonction to export symbols to the kernel symbol table. However this
fonction seems to no longer exist.
Thanks
Tahar

Klaus,
I am keenly interested in using this new debugger. After recompiling
against the 2.2.18 source tree,
and then trying to load it, I get:
# insmod pice.o
pice.o: unresolved symbol memcpy
What am I doing wrong?
Regards,
Dave Hill

It is probably worth finding out why there are so many open files.
I recently cleaned out a hacked system, which had exactly this symptom
because the hacker was a script-kiddie, and my machine didn't fit his
script exactly. So bind was eating up lots of sockets.
So when you get the machine working again, it might be worthwhile to look
for evidence of hackery: on my machine it was the existence of
/dev/.lib/lib/*
and a missing /etc/hosts.deny.

Subject: pthreads and shared objects
Date: Sat, 24 Mar 2001 05:27:31 GMT
Hi,
I am playing with pthreads library and I am stuck with creating a class
library to wrap some of the pthreads API. Purpose: to have a class
/classes that wrap pthreads API. The .so library compiles fine but
pthread_create fails in pthread_allocate_stack (SIGSEGV) when run as
root. When run as regular user the errno is 1 which is operation not
permitted. Any insight about classes exported from .so and pthreads?
Any obvious (for you) faults?
Compilation flags for both library and test app are:
-fPIC -D_REENTRANT
Link flags:
-fPIC
TIA

Exactly how, in your experience, would a CPU "crash"?
Processes crash. Hard disks crash. CPUs do not crash.

You're asking someone who doesn't know, having never contributed a
line of code to the kernel. (ok, I have actually exchanged email with
Linus, but that doesn't exactly qualify me to talk about linux does it
:) )
Anyway, it seems to me that there's no individual who does 'linux
filesystems' in general, although running the code past Theodore T'so
and/or Stephen Tweedie (ext2 developers) might be worthwhile.
Put the patch on linux-kernel and see what happens :)

goodevening every,i wanna look for a linux software which like the Visual
Source Safe(VSS)under windows98(NT).it both manage the source codes and
libs,i know that the CVS is very useful source contol.But our boss
need the libs contol also...So does anyone tell me how to do it? Thanks!

I've had a Pentium Pro 200 replaced by Compaq after the server it was
in started to crash at random. Compaq Insight Manager was reporting
ECC errors on one of the cpus. One day it was working, the next it
wasn't.

cvs, rcs, prcs, cssc (according to my knowledge and that of apt)
btw: _two_ posts, both with the same content? You bad, bad boy!
