Mixing Fortran 77 and Fortran 90 code

Mixing Fortran 77 and Fortran 90 code

[victor marian]

Sorry,

I found -fg77-calls on the web but it is for g95 not
gfortran.
I recompiled splib (Fortran77 code) with gfortran. 

but when I write
gfortran -o fileexe file.f splib.a
it still does not work. Do I need an extra option?
What about -f2c? What does it mean?

hi victor,

it is best if you can show the exact errors you are
getting.  

does it not link or are the results of the program
execution not what you expect ?

bud davis

Mixing Fortran 77 and Fortran 90 code

[victor marian]

Hello,

I want to build a program called spherical.o (Fortran
90 code) compiled with gfortran with a library splib.a
(Fortran 77 code) compiled with g77
I give the command

gfortran -o sphericalexe spherical.o -gf77-calls
splib.a

but it gives me o lot of errors as if the option
-gf77-calls were not recognised.
What could be the problem? Please Help.
I am working under cygwin.
                                                      
                                    Thank you

Victor MARIAN
