I have a project with lots of .c and .f files, which builds OK in UNIX. I am
new to g77.
My make does all compiles, then bombs with lots of undefined references from
.f SUBROUTINEs. I think I need to force trailing underscores, but I don't
know how. Maybe I need a different library. The undefined references are:
s_rdue
do_uio
e_rdue
s_wdue
e_wdue
s_wsle
do_lio
e_wsle
s_stop
s_copy
f_open
f_clos
s_paus
d_mod
s_wsfi
do_fio
e_wsfi
s_wsfe
e_wsfe
Mostly, I would appreciate a reference to documentation which explains this
specific problem.
Thanx,
Marvin E Walden

These are all routines from the Fortran run time library (libg2c.a).
Are you using g77 for linking ? (or gcc - in that case you have to
specify the location of libg2c.a)
