xdvi-pl15, taken from iacrs1.unibe.ch (130.92.11.3), pub/xdvi-pl15.tar.Z,
compiles and installs with absolutely no problems under 3.2.1 when

But they do.
AIX 3.2 has xpreview which can display postscript files if the server
has the DPS extension.

It took them a little time, but still, better late...

xlc, as opposed to cc, defaults to keeping string literals in read-only
storage.  If you want to use xlc, add the option

    -qnoro

With this, your program works properly when compiled with xlc.

It's a feature, not a bug. Try hitting "CtrlAltBackspace", which will
close the X server.

	Please don't worry about major numbers,
	mkvg will automatically generate a major number for you,
	based on what is available in the /etc/objrepos/CuDvDr class.
	It uses an internal command called lvgenmajor which uses
	genmajor() from libcfg.a.

	You don't have to give it a major number.  The only people
	who need to worry about major numbers are HANFS people,
	or other who use twin-tailed disks.

	Yes!  Again, mkvg and importvg will take care of this 
	for you.

	Yup, in fact it helps performance wise, but may hurt if
	you lose one disk, you've basically lost the whole logical
	volume.

	That means you need to increase your / filesytem.  Each volume
	group can take up to 1meg of space in / when it creates the
	map file if you leave the default of 32 PV's.  If you specify 
	a smaller number with the -d option for mkvg, the map file
	will be smaller.

   I would guess that it is store as part of the shell.  It is
   really easy to extract the programs name out of the the core using
   this the sequence:

   If anyone can explain why my program doesn't work, and what the _=
   sequence is and who generates it I would appreciate it greatly .

"_" is a ksh variable meaning "last command run from the shell"

BTW. "dbx /bin/ls core" will print "core file program () does not match..."
with the () filled in with the program name from the core file.

Hello,
you can get mtools from a lot of ftp-sites
(e.g. sun.rz.tu-clausthal.de, 139.174.1.3),
but you have to modify two lines in one
module of the sources:
Have a look at DEVICE.C, there the disk-drive-
characteristics are defined, but there is no
definition for AIX, never mind!
Take the definition for SUN-SPARC-stations,
remove #IFDEF SPARC and #ENDIF and that's it.
 
Good luck

First off, a 486/33 is not really an "AT" clone.  ATs are traditionally
286-class machines, at least in my book.  It's quite possible you have an
AT keyboard with an AT bus, but this doesn't make your box an AT clone. 

Secondly, if you want to get AIX for your PC so you can move work between
RS6k and your PC, or if you want to learn more about AIX at home, you're
probably better off going with SVR4 and something like gcc for cross-
compiling.  Or if you want a Mach kernel, you can go for <laughs>
Windows NT or NeXTStep, but this is probably more masochistic than PC AIX.   

As far as hardware requirements, I was running AIX on a 16 MB 386/33
with 400 MB of disk.  However, the OS had enough stability problems
that it was quickly dumped.  Though I've heard that there are lots of
developers off in IBM-land in Florida working on a better AIX for PCs,
I certainly wouldn't get AIX for a PC (or RT, for that matter) where
better alternatives clearly exist.  Clearly, the most important bit of
hardware in a PC running AIX is an easily-accessible on/off switch.

Thanks to all who mailed me regarding the problems I was having using -O on the xlc compiler.  A new set of binaries are winging their way to me from IBM.  Now, I have another problem.  Somewhere I have read that it is inadvisable to use -g with -O.  Why?  I am asking because I wish to use PURIFY, a memory allocation tool and it would be useful if the -g switch could be used.  Am I correct in assuming the only reason it shouldn't be used is because the output (post-optimisation) may not be reliable?

The problem is with your sendmail -- it doesn't understand how to 
resolve MX records.  MX records are used to make email addresses
for machines that may not be directly on the Internet.

In the interim, you can probably get your mail to ghost@aladdin.com
by sending to one of the following addresses:

ghost%aladdin.com@ctrvx1.vanderbilt.edu (routing through your "smarter" VAX)
ghost%aladdin.com@uunet.uu.net (routing through UUNET, center of the universe)
ghost%aladdin.com@uucp-gw-1.pa.dec.com (routing through aladdin's mail handler)

Now there's probably some twisty little token tweak somewhere that
makes IBM's sendmail know how to handle MX records, and I imagine
that someone will post "Oh, you have to do such-and-such and rebuild
this frozen configuration and kill and restart the magic poofdahs
and whammo zammo bammo everything works!"  Or...

You can FTP smail 3.1.26.  (Check archie for sites -- I got it from
ftp.uu.net.)  smail is a replacement for sendmail, and my experience
with local admins is that smail works and that rules files are typically 
a few comprehensible lines, not 15k of obscure tokens.

Can anyone help?

Are there any known bugs with the optimisation feature on
xlc (AIX 3.2).  When compiling on one particular file,
the compiler appears to "hand" for 10 minutes.  When I
inspect memory usage, it shows that AVM is being used at
a very high rate, during the last few minutes, the process
is only slowed by the pagin in and out of memory!

The compilation eventually fails with the message 
"compilation failed - out of space" (or something like that).
Meanwhile, the server warns it is low on paging space.
Obviously, there is something in this file which causes the
optimiser to fail - I have no idea what it could be.  There
are no tight loops - help would be appreciated.

Post or E-Mail.
