Autoftp and autorpm are not *console* tools.
A console tool is one that is tied to a console, typically using a
user interface based on ncurses, slang, or newt.
In contrast, autoftp and autorpm don't have any such requirement; they
may be spawned without any TTY connection. As such, they might make
wonderful components that would be spawned by a GUI application.
Examine the architecture of EXMH; it provides a full-featured mail
client that makes use of the components in MH (for mail handling), PGP
(for encryption), glimpse (text database searching).

Don't recreate them; have your program *use* autoftp and autorpm as
components, and thus assimilate all of their functionality.
Added bonuses:
- You don't have to debug their functionality!
- If their authors add functionality, you can benefit from this.

I rather think that an RPM-specific version that would be *highly*
supportive of RPM-based distributions (in the way that dselect/apt are
thus supportive of Debian) would be more worthwhile.

Gotta ask "why?"
Why do you want to have your utility invoke another utility
(kpackage) that invokes another utility (rpm) to install packages?
I see no benefit in bothering with using kpackage if your package
can do a perfectly good job of running RPM itself.
>- ability to warn the user on certain packages.
This requires that you maintain and distribute database of
warnings...

You want something more intelligent than this; filenames can
mislead...

Meaning?

If you do coverage of just RPM-based distributions, then you're
doing quite well.

Hum?
InstallShield isn't scintillatingly wonderful, but does *some* similar
things.
And I suspect that you've not made use of the binary packaging systems
for "true" UNIXes; they *do* exist...

At serious computing sites, you most certainly *do* need to think
about software upgrades, because ensuring that important systems work
correctly after an upgrade is a distinctly nontrivial problem.
Perhaps you're talking about computing systems that are run by
"witless cattle."

Subject: Using a shared library... Why won't my code compile.
Date: Sat, 22 May 1999 04:14:51 -0700
Warning. I just starting out with C/C++ on the Linux platform... here
goes.
I am trying to use a library: libftp. Only problem is that I can't get
it to work.
Here is my code:
--
extern void ftpInit(void);
int main(){
//ftpInit();
}
--
I am compiling like this:
--
c++ -DHAVE_CONFIG_H -I. -I. -I.. -O0 -g1 -Wall -c cupgrademon.cpp
c++ -DHAVE_CONFIG_H -I. -I. -I.. -O0 -g1 -Wall -c main.cpp
c++ -O0 -g1 -Wall -o upgrademon cupgrademon.o main.o -lftp
--
(-lftp is supposed to link to my shared library)
I do an ldd on my binary...
--
> ldd upgrademon
libftp.so.0 => /usr/lib/libftp.so.0 (0x4001a000)
libstdc++.so.2.8 => /usr/lib/libstdc++.so.2.8 (0x4001e000)
libm.so.6 => /lib/libm.so.6 (0x4005f000)
libc.so.6 => /lib/libc.so.6 (0x4007d000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
--
(well what do you know... it is shared linked)
So it is shared right?
Then I uncomment line 5 (//ftpInit) to start using libftp.so.0 and my
compile fails.
--
c++ -DHAVE_CONFIG_H -I. -I. -I.. -O0 -g1 -Wall -c cupgrademon.cpp
c++ -DHAVE_CONFIG_H -I. -I. -I.. -O0 -g1 -Wall -c main.cpp
c++ -O0 -g1 -Wall -o upgrademon cupgrademon.o main.o -lftp
main.o: In function `main':
/root/upgrademon/upgrademon/main.cpp(.text+0x4): undefined reference to
`ftpInit(void)'
collect2: ld returned 1 exit status
gmake: *** [upgrademon] Error 1
--
My library does have the ftpInit function because I did an "nm" on it
and it was there:
> nm /usr/lib/libftp.so.0 |grep ftpInit
00000e10 T ftpInit
What am I doing wrong? I would really appreciate some assistance here!
Could it be that ftpInit is in a different name space?
Thanks alot!

I notice that the RH6.0 has two gcc compilers in
/usr/bin/i386-glibc20-linux-gcc
/usr/bin/i386-redhat-linux-gcc
and the default one is /usr/bin/i386-redhat-linux-gcc. Anyone
know what is different between them? Because I have found some
programs fail to be compiled using the redhat one but successful
if using /usr/bin/i386-glibc20-linux-gcc.

Reply-To: [EMAIL PROTECTED]
Experiencing weirdness with Linux 2.2.6 kernel booting on a diskless
Alpha client. When mounting the local filesystems I see:
RPC: sendmsg returned error 51
RPC: sendmsg returned error 51
RPC: sendmsg returned error 51
RPC: sendmsg returned error 51
portmap: server localhost not responding, timed out
lockd_up: makesock failed, error=-5
This happens numerous times. However, if I wait long enough all my
filesystems get mounted properly. Anybody else see this? Is there a
patch?

Bruce,
Why then does my vnc setup only displays the
'x' ie a blank screen and not x windows itself
is there a command I have to type on the linux
box like
export DISPLAY ????
I have set the perl strings and location correctly
and have started Xnc on the linux box which includes
the sign on passwords.
When I start it on the NT box I type in the
same command (passwords and I connect)
ps -a shows that everything is working (vnc)
but am I missing something else ?
Many thanks
Matt

Extremely good. I'm incorporating it into my system management
procedures immediately.
My variant thereof I'm planning to make a little more, hmmm, overkilled,
as these systems get attacked by several different admins (this is
modified from my posting to the internal admins newsgroup here
announcing the imminent change):
Before making any change as root to any system, we run something called,
let's say, `pre-change', giving it a description of the change. After
the change, we run `post-change'.
`pre-change' would create a lock file (to stop two people making changes
at the same time), create /usr/changelog/stamp.{datetime}, and append
the description to a big file of descriptions, with the date and name of
the difference file prepended to it, like
990524 20:10:00 nix /usr/changelog/changed-{datetime}-start.gz Upgraded ImageMagick to
4.2.5
(It gets the username from the owner of your tty, which saving someone
playing silly buggers and running rxvt as root, would always give the
person who `su'ed to root on that terminal.)
By virtue of the lock file, it would refuse to run again until
`post-change' had been run, which creates *another* stamp file and
changed-files file, and sticks a line like this into the description
file:
990524 20:22:00 nix /usr/changelog/changed-{datetime}-end.gz [Done]
Then it kills the lock file, so you can run `pre-change' again.
This provides several additional features over bill's system, if we're
careful to run pre-change and post-change:
- We can see what changes were made when no human was making changes (eg
the logs will change, home directory stuff will change --- we may want
to exclude /home and /var/log from the changed-files lists; we will want
to exclude /proc and /var/spool/{news,wwwoffle,mqueue} and similar
directories)
- We can see what changes were made when humans *were* making changes,
to help in diagnosis &c, and this is differentiated from the
no-humans-around case by the description (the `start' stuff is what
changed between a post-change and pre-change call, so no human did
it, at least not as root)
- We can see who made changes so we can jump up and down on them when
they break
- With a suitable find command, we can see what's changed between *any*
stamped date and now. (OK, Bill's system provides this, too...)
The downsides are that it makes making changes more labourious, because
that find command is not going to be fast :( and that, well, people can
tell that *you* broke something now ;)
Something *has* to be wrong with this system. It seems too *right*; it'd
be more widely known than this if it didn't have some hidden, deadly
flaw.
Why didn't you mention this scheme a year ago, Bill? ;)

Or, rather, gcc is dead, and egcs will be renamed.
Not quite the same thing. The gcc-2.8.1 <-> egcs/gcc>=2.9.5

Can someone explain to me why we need update at all? Now that we've got
kernel threads, wouldn't it be more elegant to have everything that
update used to do in a thread? What does update do that couldn't be done
by kflushd/kswapd?
On a similar note, I'd like to see the kernel spawn a thread every minute
or so to remove unused modules. The current method - running rmmod from
cron - is just ugly.

Pentium processors have an RDTSC instruction (0x0F, 0x31) which
returns a 64 bit CPU cycle value in the EDX:EAX register pair.
This is useful because it counts CPU clocks rather than absolute
time. If you know the clock speed of the processor, the interval
between two readings can easily be converted into time.

I use xanim to view all sorts of animations.
It is open source, except for the code to do
Quicktime animations, so it would be quite possible
to grab single frame with a little hacking.
