This seems quite odd, given that /proc has the correct

There are no newer versions of ps that I can find, and
the source is proving less than easy to wade through.

Hi,
I have to port the gnu c and *all* libraries to another OS. The problem
is that there=B4s no c-compiler on that system, so I don=B4t have even
standard libraries. It=B4s an OS using the ELF standard and i386 CPUs, so=
I think it should be possible to invoke the most code Linux-similar.
But: where can I find the stdlib, and how are functions like "fopen" and
so on supported by it? The don=B4t seem to be found in the glibc...

But there are counter examples, although on an international scale.
Take the german c't (published bimonthly, approx. 300 pages per issue
at ~ $3), where I *know* that ad sales and editorial department are
strictly separated, ad sales has *no* influence on editorial contents
and a strict rule that editorial contents is _markedly_ over 50%. So
if they sold more ads, the editorial part gets expanded.

Well, counting DDJ as PC magazine would be doing them great injustice.
DDJ was and is a programmers magazine, in the same league as CUJ. And
the market for both is rather small, at least compared to that for PC
magazines like Byte, PC mag etc. .

Subject: Problem with compiling vfat in 2.3 kernel
Date: Wed, 04 Aug 1999 12:40:58 -0700
Hi All,
I had to move to a development kernel (2.3.12) so that I could use my
Tekram DC-390U2W controller, but I've encountered some compile errors
with the kernel. So far, the paraport-pc does not compile, nor does
fat/vfat support. I have a windows partition which I would like to
access
from linux, so I need to get this fixed.
I am compiling fat/vfat directly into the kernel and not as a module.
The problem is that when linking, there is an undefined symbol which is
used in:
<linuxroot>/fs/fat/file.c, line 440:
update_vm_cache(inode, *ppos, bh->b_data + (*ppos & (SECTOR_SIZE-1)),
written);
Which feature/module must I compile in addition to fat/vfat to define
this
symbol?
Thanks in advance,

Does anybody know a process that uses Port 6000, I was writing an app that
used that port and I could never get it, I tried telneting to it and I
connect but that was about it. I'm running RedHat 6.0. I looked in the
services file but there was nothing listed for that port. I even tried to
reboot in case a previous process somehow didn't release it but it was
there when I rebooted which leads me to believe that its some sort of
system process, however my 2.0.36 machine has that port open. Its not
that important since I can use any other port, Its just a little
disconcerning knowing that there is an app running on that port and I have
no idea what it is.

Freer options, but less mature, are "guavac" or the java to native code

After RTFM ;-), I installed the latest stable binutils (2.9.1.0.25) from
ftp.varesearch.com and my kernel compiled perfectly. Well, not quite. Keep
a backup of your old "objdump" as the kernel build may require it.
Right now I'm running 2.0.37 on my Redhat 4.2 system and it appears to be
working fine.

VFAT is broken in development kernels.
If you need working VFAT use older kernels. It doesn't
compile because a non-compiling VFAT module is better than
a corrupted one.
These issues would be perfectly clear to you if you did as
you should when using a development kernel - read the kernel
mailing list and archives. www.kernelnotes.com
I think if you read the kernel configuration notes for
kernel 2.2.10 you will find support for VFAT works as
well as support for your SCSI board.
