[Bug fortran/37953] New: undefined reference to '_gfortran_*'

["successful dot jiang at gmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

hi there,
I am testing a package with three source files.
I saw lots of information about solving 'undefined reference to ###', but it
stucks me.

compile the object file with
   'gfortran -c optnhp3ma.f middle3.f optnhp3.f'

when I run these objects, coupled with a problem input. Things happen...

optnhp3ma.f:(.text+0x2c): undefined reference to `_gfortran_set_std'
optnhp3ma.f:(.text+0xe0): undefined reference to `_gfortran_st_write'
optnhp3ma.f:(.text+0xfe): undefined reference to `_gfortran_transfer_character'
optnhp3ma.f:(.text+0x163): undefined reference to `_gfortran_transfer_array'
optnhp3ma.f:(.text+0x171): undefined reference to `_gfortran_st_write_done'
optnhp3ma.f:(.text+0x1e3): undefined reference to `_gfortran_st_write'
optnhp3ma.f:(.text+0x201): undefined reference to
`_gfortran_transfer_character'
optnhp3ma.f:(.text+0x221): undefined reference to `_gfortran_transfer_real'
optnhp3ma.f:(.text+0x22f): undefined reference to `_gfortran_st_write_done'


How can solve this out? it is a little urgent...

if I add the -lgfortran, like that 'gfortran -c optnhp3ma.f middle3.f optnhp3.f
-L/usr/lib -lgfortran'

errro message:
'gfortran: -lgfortran: linker input file unused because linking not done'


Please give me a hand
