[TUHS] Trying to compile cron

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. -- WWL 📚
