I do not condone my actions, and I am rarely proud of flaming. But few
things in life annoy me more than ignorance. The concept of someone
admitting they knew *nothing* of a subject, and yet still taking the
time out of their day to argue over it. I was annoyed, I don't
necessarily agree with you, although some points of your post were fair,
and I certainly dont agree with Chris Browne's points . I found it
bizarre to read a post more recently from him that seems very
intelligent, well thought out, and even knowledgable, but still, it goes
to show, you are a fool to prejudge on usenet. Oh well, until next

Okay, this is annoying. A Usenet gateway of some sort. People post

I've already got an OS that isn't a pain in the ass to install, maintain,
and use. Thanks for the feedback, but I don't consider learning a few wee
concepts a hefty cost, compared to the cost of not learning them and
depending on poorly integrated "wizards" to figure out which limited
options are least painful for me.
By the way, it's Linus who wants World Domination, I don't use Linux.

The Amiga was pretty good at that, given the resources they had to work
with, and NeXT allegedly did a reasonably good job, though I haven't had
much opportunity to play with it. I understand that QNX is going to make
a consumer version of Neutrino, which should be interesting.
But the issue isn't pitting the inexperienced against the experienced, it's
whether it's worthwhile learning to drive before getting behind the wheel.

What do you mean? I have downloaded their WordPerfect 8 for linux some months ago
from linux.corel.com or something like that. It works quite well and runs
properly as a X application (i.e. not as resource hungry as StarOffice, which is
more fully featured), but you only get to have the word processor, not anything
like spread sheet or presentations. Didn't try for long as I am mainly a latex
person. I think you mean a full Office (e.g. "CorelOffice" or something like
that) suite?

Traditionally, vfork() is/was the fast and sloppy flavour of fork(),
only meant to be used in the fork()/exec() idiom. In the olden days
(before copy-on-write was discovered), fork() did a full memcpy() of the
parent's local/global variables when creating the child. This was
considered wasteful in the common case where the first thing done by the
child was an exec(), throwing away the inherited core copy. So, to
optimise that case, the wise invented vfork(), which instead of copying
data simply let parent and child share the same copy (somewhat like
threads, but no useful mutexes). After the vfork() one party (usually
the child) had to exec() or die, anything else could cause races with
the parent.
Nowadays, with copy-on-write, vfork() is usually (definitely on
Linux) a synonym to fork(). But you'll never know when your code is run
on a PDP-11 where they are not the same.
(In case you're wondering, copy-on-write means that the memory is
initially shared, but when the child (or parent) tries to write to a
variable, the OS (with some help from the MMU) makes separate copies of
that variable. So only those variables that must be copied are copied).
ObTechnical:
Yes, I know that c-o-w has a granularity of one page instead of one
word, and that page tables must be duplicated on a fork(). But I wanted
to keep the explanation simple.

Subject: Help Compiling GCC 2.95.1 (Please!! )
Date: Thu, 02 Sep 1999 18:19:51 GMT
Okay, so I'm trying to install Gcc 2.95.1 on an Ultra Enterprise 450,
running Solaris 2.5.1.
Here's what I do, and here's what happens: (And please help!)
1. Untar gcc-2.95.1.tar.gz into /u7/gcc-2.95.1/
2. Mkdir /u7/objdir
3. Chdir /u7/objdir
4. '../gcc-2.95.1/configure --prefix=/u7/installs/gcc-2.95.1 \
--with-local-prefix=/u7/installs/gcc-2.95.1\
--with-gxx-include-dir=/u7/installs/gcc-2.95.1/include/g++'
5. Configure whirrs on for a while, doing its thing...
6. No errors, normal termination of configure.
7. 'make bootstrap MAKE="make -j 4" -j 4'
8. This whirrs on for about 15 minutes (on 4 processors, oh yeah!)
9. A few warnings, but no errors. Normal termination of make.
10. 'make install'
11. Copies files, everything still seems okay.
Now, I changedir to /u7/installs/gcc-2.95.1/, and the binaries are in
/bin, and the libs are in /lib, and everything seems alright, except
there are NO INCLUDE files in /include. The g++ include files are in
/include/g++, but there are no other headers in this distribution.
This seems a bit puzzling to me, and my stuff tends to fail when I'm
unable to include the necessary files... Hmm..
BTW: I did downlad the full 12.x meg gcc-2.95.1.tar, so don't go
there! :)
Anyone have any ideas? Is it possible that the install is noting that
I already have include headers somewhere else, so its not installing
them? They didn't get put in /usr/include, or /usr/local/include, so
I don't know what happened to them or if perhaps they simply weren't
included....
HELP!?!?!?!?! PLEASE!!!!
We've been working on this for days now, its really depressing and a
bit pathetic... :)

The most-up-to-date version, automatically formatted from the very

Another version, corresponding to Cygnus' GNUPro release, may be

Searching altavista for GDB, Stallman, and Pesch together turn up some

It's hard for anyone to do this for you because they need the same kernel
image that you have. One thing you can do is disassemble your vmlinuz image
and look for the instruction pattern '8b 03 03 43 08 39 ...' that is
shown on the last line of the oops. That will tell you where you are.
You know that you are somewhere near (or rather not so near) the eepro100_init
function, so it's the eepro driver that seems to be the culprit. If it's a
module, then disassemble the module .o file, rather than vmlinuz, with:
objdump -d <module_name>
Then look for that instruction pattern to find out where exactly it's
crashing and why. Search for a short substring like '8b 03'. There may be
multiple matches, so find the one that is followed by 03 43 08, etc.
The disassembly should show you static symbols, so
you can find what actual function the problem was in: the oops message
only relates the crash to a nearby *external* symbol like eepro100_init,
but drivers are full of static functions that do the work and often have
relatively few external functions.
If you mailed me a copy of the exact eepro100.o and eepro100.c that you are
using, along with a courtesy copy of the oops message, I could have a look at
it to determine the location in the code and the cause of the crash.
It looks like the ethernet driver was invoked at interrupt time and did
something wrong; the problem is unlikely to be related to the MD driver.

Any sufficiently advanced operating system is indistinguishable from

I'm seeing a possibly related problem with 2.3.1x - I can't login in on a
console terminal. When I type in the username (root), it simply refreshes the
line and reprompts me for the username. I'm able to do a Vulcan NeckPinch
(ctrl-alt-del) to cleanly shut the system down, and have found in the
/var/log/messages file several complaints from 'mingetty' about illegal
characters. I can run 2.1.11/12 just fine.
I'm used to dealing with strange bugs in
whatever experimental kernel series is
around, but this one's got me baffled. I
didn't see any obvious references in the
Kernel Traffic logs for the kernel mailing
list (I know I really should subscribe, but
I need to do some other things first.)
One suggestion I've been given was that
it might be a PAM problem, but I'm scared
to death to paint myself into a corner if I
change something in /etc/pam.d incorrectly
as I'm not real familiar with PAM. Thanks
in advance.
