Hi. I am trying to compile cron for the 3b2-400 and 3b2-700
and am apparently missing required libraries. The reason is
on the 3b2-400 after boot up it complains there is corruption
in the crontab for every user lp, sysadm, root and so on.

# make cron
        cc -O  cron.c -o cron
undefined                       first referenced
 symbol                             in file
el_add                              cron.o
el_delete                           cron.o
el_empty                            cron.o
el_first                            cron.o
el_init                             cron.o
xmalloc                             cron.o
el_remove                           cron.o
num                                 cron.o
days_in_mon                         cron.o
days_btwn                           cron.o
ld fatal: Symbol referencing errors. No output written to cron
*** Error code 13

Stop.

Does anyone have these libraries? Thanks.

At first I thought the el_ code was editline code but that doesn't make 
sense in cron, but then I found the General-Purpose Event List Manager.

See
https://www.tuhs.org/cgi-bin/utree.pl?file=SysVR4/cmd/cron/elm.c
and
https://www.tuhs.org/cgi-bin/utree.pl?file=SysVR4/cmd/cron/funcs.c

Does your cron source come with this other code?

By the way, how to browse the SysVR4 code at TUHS?

Try just cc *.c -o cron

I forgot to mention it is running System-5 r3 not r4..

One thing that would INCREDIBLY help people trying to help you is find
where the symbol is used, look up the variable types in the function call,
and create a prototype.  For example, both of these are valid xmalloc
instances:
   char *xmalloc(int size);
   char *xmalloc(int size, unsigned char fillvalue)
Seeing the use in the code you are trying to compile will help avoid wrong
answers.

People already likely gave you the answers, but a little leg work on your
own before posting will help.

If you're building on SVR3, cd /usr/src/cmd/cron && make -f cron.mk should suffice, all four variations on SVR3 sources I have have a cron.mk included.

Curiously, my SVR3.2 for 3B2 sources are missing elm.c and some other bits, and actually wouldn't build, if you've specifically snagged SVR3.2, you might try sources from another revision, if we pulled from the same source you're probably also missing elm.c in that specific revision. There's also an M68k version of SVR3.1 floating around out there somewhere that appears to have the necessary bits, I can't imagine there's anything platform specific in cron.

Finally, there's always good old "grep -r 'el_add' /usr/src" and "find /usr/src -name elm.c"

Best of luck!

As I messed with making a custom cron in the late 80s,
remembered the the el_ functions are for event list processing.
But you didn't specify the source of your source, by the hardware
it needs to be of System V heritage.  And a lot of that source is hard
to offically come by due to licensing.  Good way to view old SVR4 is
to look at OpenIndiana, Illumos, or OpenSolaris code bases that you can
find. You're in luck, as TUHS has a copy, see -- https://www.tuhs.org/cgi-bin/utree.pl?file=OpenSolaris_b135/cmd/cron/elm.c

Look at the Makefile for the other files you need to compile into it too.
