The developers at RH *do* produce code. They *do* do more than just
collect Linux apps into one.
Various things they do have been pointed out here in this thread. Among
them are sysadmin apps, and the install process, as well as RPM itsself.
To ignore these facts, and claim they donothing other than collect
stuff, is to appear foolish.

Why look at diffs? Just look at the patches. If you are the sort of
person who is comfortable with kernel compiling, you damn well better be
able to look at patches. The patches are applied in the process of
building the rpm. The sources are pristine. You want to know what
differences their patches make? DL the soource rpm and look at the
patches themselves. Want some, but not others? Remove the ones you don't
want and build the rpm, or apply only the ones you do want and compile
the kernel on your own. Before making remarks like this, it would help
if you actually looked at the process and source before posting
misinformation.

Wile I am not the one who posted that you lied, I will say that you are
posting information which is innacurate.
To have lied would mean you did so intentionally. RH does not have to
lead you around by the nose. If you are willing to learn system
administration, or already know it, you can use the redhat tools for a
great many things. I admin a few dozen Linux boxes, and have converted
them to either RH or added rpm to them simply because it makes my life
that much easier. As with anything, once you begin to look at it in
depth, you realize there is a lot more there.

Well...you had two options:
1. run lilo with with -u switch (this restores the boot sector
information to its pre-lilo state.
but since you killed the linux partitions this option is out and you are
left with...
2. boot from an MS-DOS floppy disk with the FDISK.EXE program on it and
after booting to MS-DOS run FDISK with the /MBR flag. This will
recreate a normal MS-DOS boot record
The above advice assumes that you want to boot to either MS-DOS or Win
95 or 98. Windows NT handles things slightly differently.

I've made a little CGI-program that is ran from .shtml. It outputs
only one line, but the problem is with that it's really made for:
It keeps track of visitor and show times and such and makes a
log. However according to my logfile it records only about half of the
visitors our counter does. Could the problem be with the file system
i'm using (fopen "a" and fprintf) if there's many hundreds of
users online at the same time? Please help someone.
Oh, I'm programming with C.

It's my understanding that Alphas are currently limited to 1 or 2 GB
of RAM under Linux, though.

Don't forget about /dev/random and /dev/urandom if you need strong
random numbers. Probably not an issue if you're using crypt(), but...

The stack size is usually unrelated to the type of compiler - why do you
think there is a problem with the stack in your program?
You can set the stack size by using ulimit (try ulimit -a, then ulimit -s [1])
but on my machine the size is 8 megabytes already - do you really have need
for a stack greater than that?
The memory is not really used until it's actually touched however, so it's
not 8 megabyte that every program uses. The stack just grows downwards,
expanding as necessary until it hits the limit set by ulimit -s.
[1] or limit in *csh

Please note though that there is no point in using COM/DCOM in a
linux app except possibly to communicate with an existing Windows DCOM
server. For all other purposes, use CORBA.

Run the preprocessor on the C code, i.e.:
gcc -E file.c | less
and look at what's around that line 179 - compare it to what it looks like
before you run the preprocessor on it.
Perhaps you have something like
void some_fun (some_type x) {
}
but "some_type" is #defined to be nothing.

Have you used "flex" elsewhere though? There are some differences between
lex and flex (whcih are described in e.g. the O'Reilly lex&yacc book -
perhaps 'info flex' mentions it too).
In the worst case you could just use lex/yacc on the other platform and
take the generated code from there and compile it on Linux. Or 'rsh' over
to another machine to run lex/yacc :)
Now it's time for Easter vacation :)

In other words, it's only the case if you want to use WinNT or Linux
and probably a couple others (don't know about *BSD, ...).

Ok, I might be able to do this. I think I might be able to pursade our admin
to let me do this.
I'll have to read the manuals on how to get at the windows mail. Can I just
use mapi to do
this?

I don't think that's going to happen. The current mail system works well
enough for
everyone except me and I think exchange is quite expensive isn't it?
Thanks for the help.

Pff :-) Old error... You got a kernel where the IDE Driver is compiled
as a module (kernel part which is loaded during run time).
So what you got is a hen and egg problem: To load the IDE Driver you
need the IDE Driver already in Memory.
Solution: Get (compile) a kernel which has the IDE Driver included
(not build as module).
I can't tell from your mail if you use a distribution. If you
do, it might be possible that you use a SCSI Kernel, which
supports SCSI (without modules) but not IDE. In that case
use an IDE kernel.
so long

Pure evil, isn�t it?
Do you have SCSI or IDE disk(s)? How many drives? Where did you install Linux,
and where does Win reside, what drives/partitions? Give us a copy of your
/etc/lilo.conf and possibly a copy of your master boot record. A partition list
shown by linux fdisk and Windows fdisk would help also.
Once upon a time, there was a bug in Windows 95 filesystem driver that yould
cause exactly the same problem under certain circumstances. I thought MS has
resolved that "issue" allready, but who knows?
