Re: [m-users.] [Beginner] Using a functions from 'libs'

My bad. What is the problem here? Is it a problem with
https://github.com/Mercury-Language/mercury/blob/master/compiler/md5.m

Making Mercury/int3s/a05.int3
Making Mercury/ints/a05.int
Making Mercury/cs/a05.c
Making Mercury/cs/md5.c
Making Mercury/os/a05.o
Making Mercury/os/md5.o
Making a05
Making md5
** Error making `md5'.
Mercury/os/md5_init.o:md5_init.c:function mercury_init: error:
undefined reference to '<predicate 'main'/2 mode 0>'
collect2: error: ld returned 1 exit status
