I am looking for the Source Code for "elm". I run SCO Xenix on a 386 machine
and am using a 386 box. I would like to find this code (ready to compile if
possible) on my system. If you can help or know where I could find this please
write me at ....!{ihnp4,uwvax}!uwmcsd1!lakesys!stevenjon@gaia.UUCP (Jonathan Corbet) (05/08/87)

The Elm code is highly non-portable, especially to machines that require special care with pointers, such as an AT. I dug around in it for a while (I'm actually running Microport, but the situation will be the same with Xenix), and finally gave up -- too many core dumps for my taste. -- Jonathan Corbet {seismo | hplabs | gatech}!hao!gaia!jon {ucbvax | allegra | cbosgd}!nbires!gaia!jon

Well, there is some cavalier handling of NULL as a pointer to a null string that causes some problems but otherwise there are only a couple problems with pointers and longs. Dave seems to have incorporated most of the fixes I sent him in the latest patches. There are still a couple problems left. You need to #undef toupper and tolower in each module that includes ctype.h. Also, building this beast on a small machine is a bit tricky. The original 1.5 distribution is working fine here under SCO Sys V V2.1 and under Intel Xenix/286 which is sort of system 3 Xenix. Following is the Makefile I used. Contained therin are most of the secrets of building this beast. There were a couple library problems with SCO that may be fixed in later versions. For SCO add -LARGE to CFLAGS. Also, add -SEG#256 (undocumented flag) to the cc line hat links elm. If a fixup error occurs during the linking, extract the module, signal.o, from /lib/Llibc.a and include the module so extracted in line 53 prior to ${OBJS}. This will cause signal.o to end up in the correct segment and make the fixup error go away. Also, you need a working version of xstr. The SCO version I have seems a bit flakey. I used the Intel Xenix version of xstr to build elm. -------------------------- line ------------------------------------------ # # Makefile for the ELM mail program. # # (C) Copyright 1986, Dave Taylor # # Last modification: August 15th, 1986 SHELL=/bin/sh DEFINE= LIB2 = # IF you're on an ACSnet system (Australia) then # you'll want to uncomment the following; # DEFINE= ${DEFINE} -DACSNET ############################## CFILES= addr_utils.c alias.c aliasdb.c aliaslib.c args.c bounceback.c \ builtin.c calendar.c connect_to.c curses.c date.c delete.c \ domains.c edit.c editmsg.c elm.c encode.c errno.c file.c \ file_utils.c fileio.c forms.c getopt.c hdrconfg.c help.c \ initialize.c input_utils.c leavembox.c limit.c mailmsg1.c \ mailmsg2.c mailtime.c mkhdrs.c newmbox.c opt_utils.c options.c \ output_utils.c pattern.c pmalloc.c quit.c read_rc.c remail.c \ reply.c return_addr.c savecopy.c screen.c showmsg.c signals.c \ softkeys.c sort.c string2.c strings.c syscall.c utils.c \ save_opts.c validname.c HEADERS=../hdrs/curses.h ../hdrs/defs.h ../hdrs/headers.h ../hdrs/sysdefs.h OBJS = addr_utils.o alias.o aliasdb.o aliaslib.o args.o bounceback.o \ builtin.o calendar.o connect_to.o curses.o date.o delete.o \ domains.o edit.o editmsg.o elm.o encode.o errno.o file.o \ file_utils.o fileio.o forms.o getopt.o hdrconfg.o help.o \ initialize.o input_utils.o leavembox.o limit.o mailmsg1.o \ mailmsg2.o mailtime.o mkhdrs.o newmbox.o opt_utils.o options.o \ output_utils.o pattern.o pmalloc.o quit.o read_rc.o remail.o \ reply.o return_addr.o savecopy.o screen.o showmsg.o signals.o \ softkeys.o sort.o string2.o strings.o syscall.o utils.o \ save_opts.o validname.o BIN= ../bin LIBS= -ltermcap CFLAGS= -O -Ml -K -I../hdrs CC= /bin/cc RM= /bin/rm -f ../bin/elm: ${OBJS} ${EXTRA} ${HEADERS} ../hdrs/elm.h xstr ${CC} -c -Ml -ND STRING xs.c ${CC} -F 8000 -o ${BIN}/elm -Ml -m elm.map ${OBJS} xs.o ${LIBS} ${LIB2} chgrp mail ../bin/elm .c.o: ${HEADERS} xstr -c $*.c ${CC} -c ${CFLAGS} -NM $* -NT $* ${DEFINE} x.c mv x.o $*.o curses.o: curses.c ../hdrs/curses.h ${CC} -c ${CFLAGS} -DRAWMODE ${DEFINE} curses.c # #initialize.o: initialize.c # ${CC} -c ${CFLAGS} -DHOSTNAME=\"gryphon\" ${DEFINE} initialize.c # # curses.c : curses.q # @../bin/quickscreen curses.q # # curses.q : # @cp curses.c curses.q clean: ${RM} ${OBJS} LINT.OUT ../bin/elm lint: LINT.OUT LINT.OUT: ${CFILES} lint -DRAWMODE -I../hdrs ${CFILES} -ltermcap > LINT.OUT listing: LISTING LISTING: Makefile INDEX ${HEADERS} ${CFILES} @echo adding file 'Makefile'... @/bin/echo \\f > LISTING @cat Makefile >> LISTING @echo adding file 'INDEX'... @/bin/echo \\f >> LISTING @cat INDEX >> LISTING @../bin/makelisting ${HEADERS} ${CFILES} @echo LISTING generated. index: INDEX INDEX: ${CFILES} ${HEADERS} @echo Creating function definition index @index *.c | sort > INDEX @echo File INDEX generated -- Greg Laskin Trailing Edge Technologies, Ltd.
