convert 'C' code to 'Fortran'

sam

Hi,
Can anyone help me find a software that can convert a code in 'C'
to 'Fortran77/90' automatically?

Thanks in advance.

Sam.

This is not really on-topic.
However, there is a slightly more topical version: Why fix something
that is not broken?
C modules can communicate with fortran modules.
Now the problem is just how to fit the two together.
Google for "mix fortran and C". It basically comes down to
providing interfaces, creating the right headers and intelligent
makefiles.

Cheers

Good luck. You'll need it. C concepts like pointers don't
translate very well into FORTRAN.

This is off-topic for this newsgroup. However, I suggest using a search
engine for f2c.

So you can use it to check your result, in the unexpected case that the
original C code fell within the subset of C used by f2c, and your OS gets
along with the f2c conventions.

Try searching for c2f then.

Maybe because the Fortran compiler's optimization is better than the
platform's C compiler. Or to make calling the code from Fortran easier.
Or a small number of other possible reasons.

Obviously, going the other way is a lot more common. The Fortran FAQ
I'll link to later says that there aren't any tools to automate the c2f
conversion.

| C modules can communicate with fortran modules.

True, but it isn't always easy. There are more issues involved in this
than I'll go into here, but there is a (long) discussion of it at
section 3.1.3 of the Fortran FAQ at this address:

And it is, indeed, a problem. ;)

Well, as the OP did not give a _good_ reasons, I assumed (s)he was not
aware of this way.

Obviously, going the other way is a lot more common. The Fortran FAQ
I'll link to later says that there aren't any tools to automate the c2f
conversion.
Yep, this I know. I would rather go for the f2c but the OP seemed
to want to have Fortran.

*g* Maybe.
Up to now, I only had the dubious pleasure of getting F77 code
to work together with C code, always the C code calling -- and
this went always straight by recipe.

Thanks for the additional information :-)
