SYS V undump (needed)

[Alan Whitton]

Munch, munch, munch

Hello,

I am looking for an undump utility for system V. We are currently running
on a Plexus P55 and are trying to get a preloaded version of TeX to
work with NO success. The utility takes an executable and core image as
input and creates an executable which has initialized variables (using
those set before the core was dumped). Is there another way of doing
this on SYS V? (someone has suggested adb but I cannot see how). We are
also running SYS III on a P60, if anyone knows of an undump for that
please respond. Please respond via mail as our news is a bit flakey right
now.

Thanks

sure answer anyway, my language skills may be our only barrier.

I frequently receive requests for an undump for this or that system (I
am the original author). While I am pleased the people like the program
so much, I have not been maintaining it for a long time (nor do I know
anyone who has). It has, for the most part, been superseded by
"unexec", a function that can be called from a running program to create
an "a.out" image (of that program). It is available for many different
systems (including SYS V), and is part of the Gnu Emacs distribution.

For those of you on the internet, the GNU Emacs distribution is on
prep.ai.mit.edu in /u2/emacs/edist.tar. You could also try sending mail
to gnu-r...@prep.ai.mit.edu. (I'm not positive this works.)
The administrators of louie.udel.edu also maintains copies of GNU
Emacs. The files are available via anonymous ftp under directory
~ftp/gnu. louie's addresses are (as of 24 Oct 1986):
10.0.0.96 louie.udel.edu udel-louie.arpa udel-louie louie udel-relay udel .

OSU is distributing GNU Emacs via uucp. Details from Karl Kleinpaste
<osu-eddie!karl> or <ka...@ohio-state.CSNET>

I can send individual copies, but my turnaround is usually pretty long
these days.

I know this isn't what the original poster was looking for, but perhaps
looking at the unexec source will suggest how to fix undump.

Has anyone hacked unexec to work with SV/286? The problem with that
system is that a given section may consist of more than one segment.
The unexec code expects three sections, period. This makes porting
GNU to, say, the 6300+ almost impossible, even if one could solve
other ugly problems.
