Is there a tool for automatically creating Fortan bindings from the C library header using the iso_c_bindings built-in module from the Fortran 2003 standard?
iso_c_bindings
I'm not interested in translating C into Fortran, but only generating bindings.
An automatic tool was used to get the gtk-fortran bindings. This is a Python script cfwrapper.py . You may be able to adapt it for your needs, although for my small problems I finally decided to make the bindings manually.

Another project to consider is h2m: https://github.com/dan-nagle/h2m
However, at this time on macOS, I cannot compile h2m.
