3b1, sc w/shared libs

[John R Ruckstuhl Jr]

Recent references to "sc" (public-domain spreadsheet software) in this
newsgroup suggest there may be experts who can advise me.

When I attempt to run "sc", I get a 2.5 Mb core dump accompanied by the
message: "Memory fault - core dumped"
I know little about software and hardware and nothing about debuggers,
but I tried to "sdb" so that this article would have at least *some*
information for those that might try to help me.  Of course I do not
know if this is relevant.

Another interesting side effect of the "sc" failure is that within that
window, it seems the escape key is remapped to *2* escapes.  I remember
that there was discussion about how effect occurs when one runs "tetrix".
Was there ever an explanation of the effect, or a patch?

I think the failure is related to my attempt to cleverly use the
libraries on the UNIX PC (without knowing how).  
I modified the Makefile as:
	0a1,2
	> SHAREDLIB = /lib/crt0s.o /lib/shlib.ifile
	> 
	57a60,64
	> # AT&T UNIX PC (3b1/7300)
	> CFLAGS = -O -DSYSIII
	> LDFLAGS =
	> LIB= -lm -lcurses -ltermcap
	> 
	69c76,77
	< 	$(CC) ${CFLAGS} ${LDFLAGS} ${OBJS} ${LIB} -o $(name)
	---
	> 	$(LD) $(LDFLAGS) -r $(SHAREDLIB) -o temp.o $(OBJS)
	> 	$(LD) $(LDFLAGS) temp.o $(LIB) -o $@
	75,76c83,84
	< 	$(CC) ${CFLAGS} -o p$(name) psc.c
	< 	cp p$(name) $(EXDIR)/p$(name)
	---
	> 	$(CC) $(CFLAGS) -c psc.c
	> 	$(LD) $(LDFLAGS) $(SHAREDLIB) -o p$(name) psc.o

It compiled and linked okay! :)
Maybe someone will see something obvious from the above... "Hey John, it
doesn't make sense to link in both curses & termcap libraries."

If you have compiled & installed "sc" successfully on the UNIX PC, and 
have a Makefile that takes advantage of shared libs, please mail a copy
to me.

    This software was is described by Bob Bond (rgb at sequent) in the 
    file "README" as the following:
    "This is a much modified version of the public domain spread sheet 
    sc, posted several years ago by Mark Weiser as vc, originally by 
    James Gosling."
    Files in this package with RCS identification are identified as
    Revision 6.1, except "help.c", which is identified as Revision 6.2.

sphere uses release 3.51 of foundation set, and uses release 3.5 utilities.

Thank you for any suggestions.
