             Bug #: 54797
           Summary: Gnu Fortran compiler does not recognize module file it
                    created
    Classification: Unclassified
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: christopher.romick@gmail.com


I am trying to compile a library of module files using make for use later in
codes, that may require mpi or on earlier created modules. I have tested the
compilation with pgfortran and intel compilers on linux with open-mpi 1.4.5 and
it works perfectly. I have additionally tested it on linux using open-mpi 1.4.5
and gfortran 4.2.1 and on Mac OSx 10.6 with open-mpi 1.4.3 and gfortran 4.6,
with both failing with the following error:

Fatal Error: File 'odesoldat.mod' opened at (1) is not a GFORTRAN module file

I have checked to make sure that I throughly cleaned the folders to make sure
the module file as well as the object file are deleted prior to compilation. 

I am using the following compilation flags:
FLAGS = -O3 -fdefault-real-8 -fdefault-double-8  -J $(MODULE)

If anyone has insights they would be most welcome.
