I ran Caldera 2.3 for a while (not the best idea) and I recall it
installing lots of stuff to /usr/local. Perhaps I'm wrong, it's been a
few months.

gcc ist the frontend of the C-Compiler. So it doesn't link the C++
standard library ( which contains cout) automatically and you will
need to add a -lstdc++ to link with that library.

hello everyone:
I want to use gdb to see my GDTR/LDTR/TTR and segment register
invisiable part(x86)
so in gdb I enter "p/x $gdtr"....etc
but the result is "$6 = Value can't be converted to integer"
and in gdb I enter "p/x $cs"
the only result is the CS, just visiable part
can anyone tell me how to view these value??
thanks for your answer

Subject: Memory issue of process under Linux
Date: Sat, 20 May 2000 15:55:17 +0800
Can anyone gives me some hints on how to make a detail measure of
memory usage of running process under Linux?
It seems that 'top', 'ps', 'free' all gives different statistics of a
running process.
Also, I have tried to compile a program by 'gcc a.c' where a.c is:
int main(void)
{
while(1);
return 1;
}
The output is a.out.
After using 'strip' to cut down the size to 3Kb and run it, 'top' said
it used up 292Kb in Size column and 252Kb in SHARED column, 'free' said
it used up about 60Kb and 200Kb shared (Calculated by free memory before
& while running the process).
Can anyone tell me where the memory goes? Thanks alot.
Jacky

QT licenses DONATE all derived works back to Trolltech. That
includes all modifications of the code. You literally cannot
patch the code without giving them the patch.
Further, if you modify the code, you can only distribute your
modifications as patches. Not as another version of QT. The
license actively prevents forking in this way. Only Trolltech
is allowed to release versions of QT.
Further, if you even LINK to QT, you have to make your program
more FREE than QT. You have to make your program's source
redistributable and make modifications of your program's
source redistributable.
Further, if you create a program that links with QT and
is private, behind your own firewall, you have to make its
source available to Trolltech upon request.
Consider the loss of freedom relative to the LGPL. With LGPL
you can create any program that only dynamically links with
the library, be it open source, closed source, or behind the
firewall. There is NEVER a requirement that you give copyright
from every program that links to an LGPL library to FSF.
Any LGPL program can be forked and redistributed under
a new name, as long as it remains LGPL.
I don't think QT does qualify as open source. It clearly
fails allowing the creation of derived works licensed under
the same license. If you create a derived work, Trolltech
has copyright of that work. You may only distribute it as
a patch, whereas Trolltech make take your modification and
distribute as their copyright. They own your work. Their
license is horribly tilted towards Trolltech. Should they
ever try to use these rights granted under their license,
there will be a true uproar.

All I ever hear is complaints from people about the fact that RAD technology
has not made it to Linux yet.
I am sick of waiting for the Borland Kylix product and found the following
product...
OMNIS Studio - see http://www.omnis.net
Also see a couple of independent reviews below....
OMNIS Studio is a Work of Art (ZDNet) -
http://www.zdnet.com/sr/stories/issue/0,4537,2421330,00.html
and OMNIS Studio brings Database Application Development to Linux
(LinuxPlanet) - http://www.linuxplanet.com/linuxplanet/reviews/1710/1/
Fully OO, connects to all the big DB's and has its own if you don't have a
big requirement, and best of all, you write one set of code and with NO
recompilation it runs on all Win platforms as well, and Mac (if you are
interested in that).
Do check it out!

The above shouldn't change your hardware config. at all. In Debian hardware
configuration is pretty much a manual affair anyway.

I imagine you could repeate the above any time you wanted to sync the client
machines' packages but I can't say I've ever tried it. Most people just use
"apt-get update" "apt-get upgrade" to keep their packages up to date. If
you have several machines that you really want to stay identical then you
might be better nfs mounting the / dir from the server or maybe using rsync.

You can have lines in your /etc/apt/sources.list like:
deb ftp://USER:[EMAIL PROTECTED]/my_custom_debs/local
and then put any custom built packages on your ftp server.

Hi Markus,
You were right. Adding -lstdc++ cured the problem. I was not
specific in the description of the problem which was:
tmp/ccmy4nbs.o: In function main:
tmp/ccmy4nbs.o: Undefined reference to 'cout'
tmp/ccmy4nbs.o: Undefined reference to 'stream::operator(char const*)'
Thanks david

The onlything Peter left out was autoconf. Granted, not every user
wants to use this install method; however, an install method it is.
Many, many people have used it as such.

To some extent I agree. Installing an operating system is not for the
faint of heart. I would _never_ ask my mother (or my dad for that
matter) to install an operating system.
While I don't think OS installs are the exclusive domain of
technitians in computer shops, operating systems don't install
themselves. MS-Windows nearly installs itself mainly because it makes
all kinds of decisions for you. I think that Mandrake and RedHat are
fairly easy to install. I'm sure others are as well, but I've never
tried any of them. The only think I find really lacking is on screen
documentation explaining what the options mean. Mandrake tries and
makes a good effort, but still needs improvement.

Althoug CRTSCTS does have RTS in its name, RTS is not affected by
CRTSCTS. Its function simply is to stop the data transmitter, when
CTS is not active.
