Hi did you try cfortran ?

It is a header only file what allow to link fortran with C and vice versa.

I use debian package and i maintain upstream.

http://packages.qa.debian.org/c/cfortran.html

Please report bug here
http://bugs.debian.org/cgi-bin/pkgreport.cgi?repeatmerged=no&src=cfortran

And download from here

http://bugs.debian.org/cgi-bin/pkgreport.cgi?repeatmerged=no&src=cfortran

I plan to modernize it, so please test it and report any error.

Please test plain old fortran call first not function that are part of module.
