Linking several object files

[Roberto Bellasio]

Hi,
I hope this is the correct place to post my question, otherwise I
apologise.
I'm trying to compile an atmospheric dispersion model written
mainly in Fortran and with a single file containing some C
routines. There are a total of about 360 files. My previous
attempts with Lahey Fortran90 are failed due to the presence of
the C routines and to the fact that Lahey F90 seems to be
compatible only with MS Visual C and to an old version of Borland
C (and maybe to my bad knowledge of C).
Yesterday I discovered gfortran, I tried to compile a
simple Fortran main with a C routine and the attempt went well.

The 360 files are placed in 12 different directories, a makefile
would be very useful but, if I understood well, it is not yet
available. Therefore, using DOS batch files and Perl, cycling in
all the directories, I have produced all the object files of the
Fortran and C routines, and now I need to link them. This is
where I have the problem, since if I use

gfortran -o myprog.exe f1.o f2.o ... fN.0

(where fi.o are the object files with their path) the list of
object file is too long and I get an error (from DOS, not from
gfortran). Is there any way to create something similar to a
response file and to refer to it during linking? Do you have any
suggestion to solve my (probably trivial) problem?
Thank you in advance.

Best regards
Roberto
