You might want to check out KAI 's compiler. There compiler has always been
extremely close to the standard and they're multi-platform.

Depends on which driver you are using. For printing info for linux, visit
http://www.linuxprinting.org/
For the HP Deskjet 1120C, you can either use the cdj850 driver or the
gnome-print stp driver which should give (eventually) better results.
http://www.linuxprinting.org/database.html
has the details on all the printers.

gcc follows the standard as closely as possible (if it doesn't, then
its a bug and you should report it to the gcc developers) in -ansi
mode. I presume your third party code is sufficiently non-ansi that
gcc refuses to compile it?
I detect a slight dissonance here with your otherwise commendable
standards :) But if you have to use some non-compliant 3rd party code
then that's the way it is...
Its possible that your third party code is using features missing from
the stl which ships with gcc. If so, note that a more recent port of
the stl is slightly more fully featured. Check http://www.boost.org/
for some details.

Subject: lilo and minimize linux
Date: Thu, 19 Oct 2000 22:35:54 GMT
I am trying to fit linux onto a 60 MB harddrive. Obviously, the
drive is too small for a standard linux installation.
My first question is how to install lilo on the drive and make it
boot linux. I tried to partition the drive using: fdisk /dev/hdc (the
drive is connected as secondary IDE master). I just assign
a single partition #1 (hdc1). Then I make the file system using mkfs, and
then mount the harddrive as /mnt/d. Then I copy a few file from
my original RedHat 6.1 over. Here is an output from "ls -l /mnt/d"
total 927
-rw-r--r-- 1 root root 4568 Oct 17 14:33 boot.b
-rw-r--r-- 1 root root 285018 Oct 17 16:19 initrd.img
-rw-r--r-- 1 root root 250 Oct 17 17:17 lilo.conf
drwxr-xr-x 2 root root 12288 Oct 17 14:30 lost+found
-rw------- 1 root root 13312 Oct 17 16:21 map
-rw-r--r-- 1 root root 622784 Oct 17 16:18 vmlinuz
The new modified lilo.config is as followed:
boot=/dev/hdc
map=/mnt/d/map
install=/mnt/d/boot.b
prompt
timeout=50
default=linux
image=/mnt/d/vmlinuz
label=linux
initrd=/mnt/d/initrd.img
read-only
root=/dev/hdc1
I then run: /sbin/lilo -C /mnt/d/lilo.conf
I then reboot the system and configure the BIOS to boot from the
secondary master IDE (it can boot up fine from a secondary master IDE
with DOS). However, I only get a bunch of 01 01 01 ... on the screen.
What did I do wrong ? What am I missing ?
I apologize for the long email. Any advice is appreciated.
Thank you in advance,
hung

You're on a class B network, so the default netmask is 255.255.0.0, and it's
logical: the default broadcast is based on the default netmask.
So, you *must* manually set broadcast if you want to use a sub-net.

I should observe, as the one that initially suggested "bluster," that
the disputing over Qt/KDE has historically included a sizable
population of people that _don't program_ that, for whatever reason,
decided that they felt GNOME was Their One True Answer, and that used
the licensing of Qt as an _excuse_ for "blustering" about it.
There were also people [particularly associated with Debian] that were
_concerned_ about the licensing of KDE and Qt, concerned that the GPL
was not compatible with the TrollTech license.
There is a distinct difference between these two groups; the latter
have been happy enough to let KDE enter the "blessing" of Debian once
their perceived licensing issue was sorted out.
In contrast, those that were "blustering against KDE" were _really_
holding to a dogmatic position that "Qt/KDE are Bad," and that dogma
doesn't change just because of a license change.
That may not clear things up, but it's worth a try...

Subject: making a boot disk
Date: Fri, 20 Oct 2000 05:30:07 -0000
I am trying to make a boot disk from a 2.2.16 kernel I obtained from
www.kernel.org. I follow their directions exactly and everything compiles,
no errors. I am using the command "make bzdisk" to compile the final
kernel. Every time I try and boot from the floppy I get a kernel panic.
VFS:Cannot open root device 00:11
Kernel panic: VFS:Unable to mount root fs on 00:11
This apparently means that it cannot find my file system. I want it to
use my hard drive's filesystem, rather than create one on a floppy. I've
tried using the "rdev" command to fix this but I get the same error. The
hard drives are both scsi, hdb1 and hda. Right now the system is running
RedHat 6.2. (In case anyone is wondering, I need 2.2.16 to compile some
modules for my LRP box which runs 2.2.16. RedHat's RPM kernel of 2.2.16-3
will not work.) I've read through the documentation HOW-TO on creating a
boot disk, but some of it is still foreign to me. Any help on how to fix
this would be greatly appreciated

Hi,
A good starting point would be to get hold of a copy of "Linux Device
Drivers" by Allessandro Rubini (ISBN 1-56592-292-1) at a bookshop near
you.
Failing that have a look at the source code for say one of Don Becker's
ethernet drivers in /usr/src/linux/drivers/net.
Another useful repository of information is the Linux cross-reference
site (http://lxr.linux.no/). With this you can piece together what calls
what and find macro/function definitions etc.
Here is a simple 'hello world' for a module...
#define MODULE
#include <linux/module.h>
int init_module(void)
{
printk("Hello World from modulespace\n");
return(0);
}
void cleanup_module(void)
{
printk("<1>Goodbye....\n");
}
Compile with:
gcc -c -o hello_mod.o hello_mod.c
Then (as root) install it with:
insmod hello_mod.o
Check it is there with
lsmod
& remove it with
rmmod hello_mod
Note: the printk statements will appear on the root console so if
running from an X term (or other such terminal from X) you won't see any
output but you should see them in the system log file
(/var/log/messages).
HTH

Try this instead...in hosts.allow put:
in.telnetd: 127.0.0.0: ALLOW
in.telnetd: 192.168.0.0: ALLOW
ALL: ALL: DENY
Then delete hosts.deny. The read the man page hosts_options(5), which defines
a number of extensions to the ACL, like the ALLOW and DENY keywwords, and
essentially does away with hosts.deny. This is how my system is setup, using
just hosts.allow, and it makes things much easier to manage.
Note that in hosts.allow I've given the full network address (ie, all four
octets). This may also have been a problem, but its what I do here and it
works :)

Since the only 'reboot' (i.e. "shutdown -r now") I know in linux will
start with the boot message of the Graphics card followed by counting
and testing the RAM this is probably not what you want.
And I see no way of doing a real reboot and keeping RAM untouched (How
would you know where you put your data?)
But do you really need a reboot? What would the reboot be for? Maybe a
switching down to single user mode and back up and restarting all
demons and services is enough?
