Hello:

The following code compiles fine under C++ 2.1.1:

#include <iostream.h>

main()
{
    char a = 'a';
    cout << a << '\n';
}


However, under C++ 3.0 I get errors:

/usr/bin/ld:
Undefined:
ostream::ls_complicated(char)


I've tried linking with libC but I get the same problem.  Is this a
bug, or do I need to link/include something new?  I've checked the
release notes but saw nothing applicable.  Thanks for any help!

Paul takes the prize.  Each of the copies of the scribbled mtab that I had
saved for posterity showed up as BAD/DUP in phase 1 of the fsck.

Of course, how they got that way in the first place is a mystery since I
kept creating new mtab files which kept having this happen to them.

Thanks Paul!

Looks to me like your mtab and /etc/wtmp files are cohabitating.  That
is, they are both using a particular block of the file system.

I'd suggest you go into single user mode and fsck /.  Expect some
things such as DUP blocks.

The other day, I needed to install the cdsio software from the 4.0.5
distribution. Since I've installed this option many times before, I know
that it contains a single file, /usr/sysgen/boot/cdsio.o.

Inst claims that the file must be installed from the mini-root, and
absolutely refuses to install it while running multi-user. Now, I know that
there's only one file in there, and I know how to type '/etc/autoconfig -f'
and 'telinit q' to build a new kernel and install it.

Instead, I had to take the machine down, load the mini-root (across the net,
ugh), install, and reboot. This took much longer than it should have.

For my future reference, Is there an "Expert Administrator" option for inst?
(I know this is all fixed in The Next Release, so I'm not going to bother
asking for a fix...)

I've come across a failure of the su command to actually set the uid,
but doesn't report the failure.  The situation is this:

A directory on an NFS mounted file system (exported rw, no restrictions)
is owned by me, owned by a group that my Indigo doesn't know about, is
mode 2750.

drwxr-s---   2 cruff    1558         512 Jan 28 09:22 .

I am not a member of group 1558 as far as my Indigo knows, either.  When
inside this directory, a plain 'su' command reads the root password but fails
to set uid=0 and doesn't say anything.  Is does return status 1, however.

I had exactly this problem when I first received C++ 3.0, under IRIX 4.0.1.
It was due to having an incompatible version of libC.a, which is not included
on the C++ 3.0 distribution, but rather is part of IDO (dev.sw.libC).
When the next 4.0.XXX CD arrived, it updated libC.a, and the problem went
away.

==> IDO 4.1 is required for C++ 3.0.

I would comment that the CPU upgrade is probably the more worthwhile and
cost effective. The G graphics options are pretty good, and unless you're
doing some really heavy-duty graphics Elan just isn't worth it. We had
20G's and Irix 4.0 wasn't usable. Bump up the CPU and they beat the
heck out of most other machines.

>As for cost effectiveness,  you'll have to contact your local SGI sales 
>person for pricing...

I think ours was about $7K per trade-in. SGI sent out their Atlanta area
support guy to do the changeouts as well. The kit includes things like
a different fan assembly to change the air-flow rate. It's a little
more than just an E-mod swap. Of course our cost also reflects that
we were upgrading memory-wise, but keeping the 24-bit z-buffered G cards.
Prices have probably gone down a bit.

No, it isn't available at all under 4.0.X; yes, it is part of 5.0, and

I'm not sure that I see how DSO's are going to reduce your development

I've seen problems on complex networks with lots o' subnets, but haven't
heard of any problems on the same subnet.  Is there a heavy load on the
network?  Does ping show 0% packet loss between the diskless and non-diskless
machines?
 
|> Occasionly bz on the diskless stations doesn't see any other
|> bz programs running.

Bz will only add a player after it 1) receives game packets from the other
player's machine, and 2) it receives a acknowledgement packet from the
other machine that it is receiving packets.  If you have packet loss, it's
conceivable that the acknowledgement packets just happen to be among
those being dropped (so the other players aren't added).

Check the log file, /usr/tmp/bz.log.  It may provide some clue as to who is
not receiving the packets (check on all machines involved).

If you're playing the default game (with team flags enabled), bz has to do
a bit more validation of players to make sure that everybody can see
everybody else (due to the way flags are treated).  When you play "bz -noflag",
this constraint is relaxed.  In this case it is only necessary that you
and the candidate player to be added see each other, not that he see
everybody else that you can see.  This may or may not make any sense in the
way I have described it, but just try "bz -noflag" (on all the machines) to
see if that helps.  You'll be able to choose teams, but no flags will appear.

Perhaps one of the SGI networking gurus can suggest other possibilities.

By the way, what's the configuration of the diskless stations, particularly
memory?  The process size of bz is ~8MB according to ps.  If your diskless
systems have less than 32MB, you're probably swapping which could be impacting
the net. :^)

I have a problem with one of my 4D20s.  It will occasionally crash with
a memory error (PANIC: IRIX killed due to memory error at physical address
0xXXXXXX).  It will do this about 4 times over a couple of days, and then
it's fine for a month or more.  Then it does it again.

The problem is that the error is not always in the same place -- not even

nothing wrong with the machine at all.

Any suggestions will be most welcome.

The 4D/80 uses the ENP ethernet board. It's likely the PROMs on your
board don't support multicasting. Run "hinv" and look for 
    ENP-10 Ethernet controller: enp0, firmware version 4 (SGI)
If the version is not 4, contact your support person for the ENP PROM upgrade,
which is documented in Field Bulletin 87.

You're nuts! A _good_ mechanical mouse is much better than an optical
mouse IMHO. Of course the operant word is _good_ since I'm not very happy
with the low quality of SGI's current litter -- they keep dying on us
with frightening regularity (the mice fail to move the cursor in one
or both directions). This isn't a cleaning problem either since we
know how to clean the little critters and it doesn't fix the problem.

If you want to look a GOOD mechanical mouse, look at MicroSoft's --
now that's a MOUSE!

 8       volhdr                0  (   0)         3816   (   3)
10       volume                0  (   0)      2107704   (1657)

It used to have no partition 5, and partition 6 was everthing
from the end of partition 1 (cyl 666) to end of disk (cyl 1657),
but I split p6 up into p5 and p6 and did mkfs on p5.

Okay -- now I want to use growfs to expand p1 to include p5.
I gather from "man growfs" that I can do this without using logical 
volumes if I just change partition setup so that p1 expands to 
include p5, i.e.

 1          efs  yes      338352  ( 266)      1188048   ( 934)   /usr/people

and then do  growfs -s 1188048 /dev/dsk/dks0d3s1.

So the big questions are these:
Is this all okay?  Any reason such a thing should not be done?

(I experimented first by expanding p5 to include p6 and then growfs
on p5.  It seemed to work okay, so then I adjusted partitions again to
split p5 and p6 up again to the state shown above.  Before I go
ahead and try it for real on /usr/people, I thought I'd better ask.
Yes I'll do backups first.)

Sort of related question: if I decide to chicken out of all this,
how do I make partition 5 go away?  I see how to use fx to
restore p6 to its original parameters but I don't see how
to tell it to get rid of p5.

Thanks for your words of chastisement and/or reassurance.
