older Linux: undefined reference to `clock_gettime'

[cstrotm]

Hi,

I'm trying to install oksh on an older Debian 6 ARM linux (on a machine that cannot run a newer linux because of custom kernel. But I like the machine and would like to keep it running).

I install via pkgsrc. However the issue seems to be a oksh issue, not with pkgsrc.

The linking step fails with

cc -O2 -D_FORTIFY_SOURCE=2 -DEMACS -DVI -w -D_GNU_SOURCE  -c vis.c
cc -Wl,-R/usr/pkg/lib -o oksh alloc.o asprintf.o c_ksh.o c_sh.o c_test.o c_ulimit.o edit.o  emacs.o eval.o exec.o expr.o history.o io.o jobs.o lex.o mail.o  main.o misc.o path.o shf.o syn.o table.o trap.o tree.o tty.o var.o  version.o vi.o confstr.o reallocarray.o siglist.o signame.o  strlcat.o strlcpy.o strtonum.o unvis.o vis.o -lcurses

This can be fixed by linking with "librt"

${PROG}: ${OBJS}        ${CC} ${LDFLAGS} -o ${PROG} ${OBJS} -lcurses -lrt

Maybe this can be detected in the configure script and added if needed.

Should be fixed now. Thanks for reporting!
